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

Sergiy Horef review for How to Convert

Sergiy Horef (Mizyigres)

As seen on

When you normally Google "heic to jpg" ↓

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

🤕

There's an easier way

Convert files securely with an all in one tool

👋 Say goodbye to privacy concerns and unsupported formats.

Use the secure, locally running file conversion app that strives to handle almost any file type. If you find a format that isn't supported, get it added. I'm building in public.

  • Save time by converting batches of files simultaneously. Drop multiple images, videos, or documents and convert them all in one go. Perfect for processing entire folders or photo collections.
  • HEIC to JPG, RAW to JPG, WebP to PNG, PNG to ICO. Configure quality, resize images and compress. Handles professional formats like PSD and camera RAW.
  • Precisely crop images and videos to focus on what matters. Remove unwanted areas, adjust aspect ratios, and create perfect thumbnails. Works with all popular image and video formats.
  • MP4 to MOV, MKV to MP4, AVI to MP4, WebM to MP4, video to GIF. Adjust quality, resolution, and codec settings.
  • MP4 to MP3, WAV to MP3, FLAC to MP3, M4A to MP3. Extract audio from almost any video format. Set bitrate and quality, compression and other settings.
  • MD to PDF, DOCX to HTML, EPUB to PDF, HTML to PDF. Create ebooks, documents and presentations in multiple formats.
  • Convert email files like EML and MSG to HTML, PDF, images, and text.
  • Don't let email and website size limits stop you. Compress images and videos to a fraction of their original size. Reduce file size without losing any noticeable quality.
  • Do 3000+ conversions with advanced configuration options. Runs entirely on your device - your files never leave your computer. Runs on the Web or offline as an app for Windows, Mac and Linux.

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.

  • I'm Jake, an independent developer and PhD student. Purchasing or sharing this tool helps me continue to maintain and improve the site and app. Support is never required but always appreciated. Follow me on GitHub, Medium and X to keep track of what I'm up to or to say hi.
  • 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.
