Great app! Finally something local to convert from anything into anything else, instead of every time going to google "convert x into y online".

Lost privacy with tools that send your files to unknown servers
Frustration when a file format isn't supported
Confusion dealing with complicated command-line tools
Risk of exposing sensitive files during conversions
Overwhelm from managing multiple tools for different file types
= Too many headaches with traditional file converters

FAQ
Frequently Asked Questions
- If you purchase, you get access to the official prebuilt app to convert as many files as you need completely offline. You also get support with your file requirements.
- You will get the app with faster conversions and better file support by communicating with sips, LibreOffice, ImageMagick, FFmpeg and Pandoc running locally on your machine. Your purchase supports ongoing development of How to Convert and helps maintain the free demo linked at the top of this site.
See here for a full list of all the supported file conversions.
How to Convert acts as a drag and drop user interface to communicate with its own custom conversion software and a bunch of command-line tools in a way that is accessible to non-developers. It can execute any of the following tools as separate processes via shell commands: sips, FFmpeg, Pandoc, LibreOffice, ImageMagick, MiKTeX (Windows), and MacTeX (macOS). If needed, installing these tools is simple and easy with step-by-step instructions provided in the app. If you face any difficulties, please reach out for help!
It uses some third party tools, simply because they are the best tools for the job, but are difficult to use if you are not comfortable with the command-line. Some of these tools are open source, so you can always modify their separate executables and access their source code. If you're curious, please check out these amazing tools by clicking the above links and consider supporting their developers!
This approach ensures compliance with licenses by maintaining clear separation between How to Convert and other tools - they remain independent programs that are invoked through standard shell commands. Visit the Settings → About section in the app to view full license texts.
Yes, all files are processed locally in your web browser and do not leave your device. If you get the app, then files are converted completely offline.
Your files are not sent to external servers like other file conversion websites or apps. How to Convert or its developer cannot see or store any file you convert.
You can verify this by switching off your Wifi or inspecting with Chrome Developer Tools. Check it yourself.
- How to Convert strives to support almost any file type. If you have a file that is not yet supported, submit an issue on Github to get it added!
- If you have accessibility needs, are a student, or live in a lower-income country, please contact me at jake@howtoconvert.co for a discount. I want to make this tool accessible to everyone who needs it.
- Feel free to contact me anytime at jake@howtoconvert.co. I'm happy to help with any additional queries you may have.
