OCR or Optical Character Recognition is a sophisticated software technique that allows a computer to extract text from images. In the early days OCR software was pretty rough and unreliable. Now, with the tons of computing power on tap, it’s often the fastest way to convert text in an image into something you can edit with a word processor.
Converting Audio to Text With a Smartphone Speech to text apps for Androids and iPhones can help you generate transcriptions of your audio and video files. Open an app like Speechnotes on your Android device and play the file you’d like to transcribe on your computer to start converting speech into text. Just keep in mind that the text files.

These ten applications offer different takes on the task of OCR, without a price tag and across multiple platforms. If you’ve been looking for a way to turn pictures into words, you’ll almost certainly find the best free ocr software you need below.
FreeOCR (Windows 10)
FreeOCR is a basic free OCR software that offers all the core functionality you’d want from this type of software. For starters, if you have a TWAIN scanner (which is basically all of them) you can directly scan and extract text from paper. Image imports work as you’d expect as well. This includes multi-page documents in TIFF and PDF format as well.
FreeOCR uses an Open Source engine originally developed by Hewlett Packard and eventually released by Google for everyone to use. It’s known as “Tesseract”. Tesseract has some neat features, but one of the most interesting is its automatic layout detection system. This means you don’t need to spend time tediously drawing rectangles around discrete blocks of text.
SimpleOCR (Windows 10)
SimpleOCR is a basic OCR package that can convert typed documents into text, directly from your scanner. The name, SimpleOCR, is quite literal in this case. If you have documents that exhibit any form of complexity, such as columns or that don’t have perfectly crisp scans, SimpleOCR can’t get the job done.
Of course, Simple Software is happy to sell you a more sophisticated solution for a few bucks, but if you just want to OCR some standard blocks of text, this is one option that won’t cost you a penny and is as simple to use as the name suggests. As a bonus, it supports handwriting recognition!
Easy Screen OCR (Windows, Mac, iOS & Android)
Easy Screen OCR is a small, best free OCR software that relies on a cloud-based, Google-powered recognition engine. As you might expect, this means that you need to have an active internet connection for the software to work. If that’s not an issue, you’ll find quite a useful tool here.
This OCR application is intended to extract text from screenshots, letting you copy text from websites or any other text that’s on-screen. What’s particularly cool about this is the support for more than 100 languages. If you want to translate (for example) Japanese text, you can simply take a screenshot and have Easy Screen OCR do it for. If this is something you need to do often, it also helps that you have the option to set custom hotkeys.
While this is not a traditional OCR application, there are plenty of workflows around these days that involve extracting text from the images you’re working with. Easy Screen OCR makes that task as easy as a few keystrokes.
Unfortunately the latest version of the software (1.4.2 and up) requires a subscription fee after 20 uses. However, older versions of the software are still free to use.
Capture2Text (Windows 10)
Capture2Text is an interesting little application with a narrow, but very useful function. It’s used to OCR text from what’s currently on your screen. You press a hotkey, select the zone of the screen you want to OCR and then it sends the result directly to the clipboard, so you can paste it into a word processor.
Capture2Text is a portable application, so you don’t need to install it. Just run the executable and you can use it on any Windows system from version 7 and up. The software is Open Source as well, so you can copy and modify it as you like, as long as you comply with the terms of the GNU license.
It’s not fancy by any means, but if you want to rapidly grab text from images that you are handling, this is a great piece of software to do it.
A9t9 (Windows 10)
If you’ve never ventured onto the Windows Store, you may be surprised to find that there are actually plenty of free and Open Source applications there. The a9t9 app is just such a gem and comes with no strings attached at all. There are no adverts and it promises pretty robust OCR performance.
A9t9 supports quite a long list of languages, although not as extensive as some of the other options on this list. If you’re a Windows 8.1 (or up) user who needs OCR right now and don’t want to spend any money, then simply click a single button on the Windows Store app and seconds later a9t9 will be processing your images into documents you can edit.
Adobe Scan (Android & iOS)
Adobe has an absolute ton of mobile apps out in the wild. Some are pretty great, while many seem to be little more than experiments. Adobe Scan falls into the former category. It’s a polished camera scanning and OCR application that will run on either Android or iOS. There’s no charge and you don’t need to be subscribed to any Adobe services.
Of course, the final document is a PDF, which you can only directly edit with a paid version of Acrobat, but copying the text over to a word processor of your choice is no hassle, if we’re being honest.
One of the best features of the Adobe OCR software is its ability to recognize handwriting. Of course, good quality handwriting will be better recognized. Don’t expect it to decipher something you can’t read yourself. Like your doctor’s prescription notes.
There are a few other reasons to try out Adobe Scan. The ability to automatically scan, OCR and contacts from a business card is very cool. In fact, if you spend a lot of time meeting people, it could save you a heck of a lot of time.
The app also has, as you’d expect from the creators of PhotoShop, a small set of touch-up tools. So you can clean up the images before trying to extract text from them.
Office Lens (Android & iOS)
When the first phones with built-in digital cameras came to market the quality on offer was truly awful. The resulting images weren’t really useful for anything and you certainly couldn’t make out fine detail such as text.
Today, the sophisticated cameras found on even budget models offer high-resolution images that are good enough to use as a replacement for a document scanner. For example, the Google Drive app lets you make some pretty good scans using nothing but your phone camera.
The Office Lens app by Microsoft not only lets you scan documents, it allows you to OCR them on the fly. So you could take a snap of someone’s business card and immediately have the text ready to copy into your contacts list.
Office Lens is a standalone application, but its functionality is being built into other MS Office apps as well, so if you’re already using those it may not be necessary to download this independent app. Then again, sometimes a focused, lightweight app is exactly what the doctor ordered.
English OCR (iOS)
English OCR is a free OCR app for iPhone and iPad that makes it pretty easy to quickly take a snap of a document and convert the text in the photo into a digital format. It’s released under an Open Source licence, but the developers use adverts to help carry the costs of developing and supporting the application.
There is a paid “Pro” version that has exactly the same functionality as the free edition. The only difference is that the Pro version removes all adverts. So if you are OK with a few ads, you don’t need to put any money down at all.
Reading Between The Lines
The promise of a paperless world has, so far, failed to materialize. Which means OCR technology will remain an important part of the bridge between the digital and analogue worlds.
Armed with the OCR apps above, you should never have to laboriously retype a document ever again and, best of all, they won’t cost you a cent.
June 2017: a key component for these instructions is no longer actively maintained, so these instructions are no longer valid for Modern Mac configurations.
I listen to podcasts. I watch videos. I watch podcasts of different languages. But more than anything I read and write. I practice languages. That’s just how I roll. And sometimes, my ramblings bring me as far as understanding English meaning of some specific kikuyu translation texts.
Frequently I want to save an audio snippet or video clip for future reference. Sure I could save the source media file, if I had unlimited disk space. But what I usually do is keep a link to the original source and text synopsis of the snippet. That both saves on storage and makes future searches for that particular item simpler.
If you’re like me, you really want the original text more than a synopsis. It take s a bit of extra effort, but I have a nice solution that uses only a Mac and open source software. Read below for instructions on converting an MP3 audio file to a text document.
The Basics of Configuring Your Mac to Transcribe .MP3 Audio
Here’s what you need:
- The original media (.mp3 file, for example)
- Soundflower. Soundflower is an application that creates a virtual audio channel and directs audio input and output to physical or virtual devices.
- Audacity. Audacity is a free application for recording and editing sounds.
- TextEdit.app. TextEdit is the default text editor/word processor that is included in Mac OS X.
Follow the instructions on the developer websites to get all of the software installed and working on your system. Once you have the software installed, the next step is to configure your Mac to use Soundflower for dictation.
- Open System Preferences and click on “Dictation & Speech”
- Select the Dictation tab
- Select “Soundflower (2ch)” as the dictation input source
- Click Dictation to “On”
- Tick the “Use Enhanced Dictation” box
Your Mac is ready for dictation. When dictation is turned on in TextEdit (or a another word processing app), your Mac will transcribe sound from the Soundflower input source.
Getting Your Audio and Text Files Ready
Next, you need to queue up the audio file in Audacity and direct output to Soundflower. For those who are new to Audacity, this will be the trickiest step. But relax, you don’t need to learn much about Audacity beyond deciding what section of sound to play and how to select the audio output from the default speakers to Soundflower.
- Launch Audacity
- Import your audio file into audacity (File–> Import, or simply drag the file into the center of the Audacity screen.)
- Click the play button to give it a listen, then click stop once your confident you have the right sound clip/transcription area.
- Choose Audacity –> Preferences –> Devices. Under playback, choose “Soundflower (2ch)” to switch the output from the onboard speakers to Soundflower. Click “OK”
With Audacity and your sound file queued up, its time to turn your attention to TextEdit.
- Launch TextEdit
- Create a “New Document”
- You may want to add some meta data to the document, such as the podcast name, episode #, publish date and URL, to go along with the key transcript.
- Position the cursor in the file where you want the transcript to appear.

And … Action!
It’s time to start audio playback and dictation transcription. Here both sequence and timing are important:
- In Audacity, move the scrubber start location 10-15 seconds before the key transcription area.
- Press “Play.” The scrubber and meters will start moving, though you won’t hear any sound. The audio signal is going to Soundflower instead of to the speakers.
- Put focus on Text edit and position the cursor where you want the transcription to begin.
- Select Edit –> Start Dictation. (or use the hot key combination, Fn Fn). A microphone icon with a “Done” button will appear to the left of your document.
- Text will start appearing in the document. It will likely lag by about 3-5 seconds.
- After approximately 30 seconds press the “done” button. Transcription will continue until complete.
This is the fun part: watch as transcription happens in real time right in the document window. Look Ma, no hands!
And now you have the original text (and most likely a few errors) as text to save. In the future you can easily search and retrieve the information.
Mac Apps To Convert Old Audio Into Text File
An Excellent Alternative: Google Docs Voice Typing
While the solution above works great for offline work, one alternative with a lot of promise is Google Docs. The Voice Typing feature work much like the dictation service in Mac OS. It has the crowdsourcing advantages and privacy disadvantages of other Google products. If you’re OK with that, I found Voice Typing to do an very good job with accuracy and it can go longer that Mac OS dictation.
To use Google Voice Typing, follow all of the steps above with Soundflower, Dictation preferences and configuring Audacity. Instead of using TextEdit, you’ll want to start the Chrome browser and create a Google Doc. Once you are in document, Select Tools –> Voice typing
The user interface and process of starting and stopping transcription is the same as with TextEdit.
Dictation and Transcription Limitations
This process sets you well on you way to the goal of a high fidelity audio transcription. But it will be short of perfect. Here’s what you can do to go from good to perfect:
Convert Text To Audio Online
- Understand that Mac OS dictation transcription works for a maximum of 30 seconds at a time. If you need longer, you may want to use an alternate technology such as Dragon.
- Audio playback needs to start before dictation/transcription begins in TextEdit. TextEdit needs to be in focus for dictation to work. If you set the Audacity scrubber a few seconds ahead of target snippet, you’ll be fine.
- Transcription cannot intuit punctuation. You’ll need to add that after the fact.
- If you have multiple speakers or a noisy background, you may need to complete one additional step of creating a pristine audio file to work from. This can be done by listening to the sound through headphones and speaking the text into an audio recorder. Use the recording of your voice to drive the transcription.
