Converters that run on your device
Every converter on this page runs in your web browser. The conversion code is downloaded once, and your files are read, converted and saved on your own computer or phone. Nothing is uploaded, so there is no waiting for uploads and downloads, and no copy of your file is left on someone else's server.
The converters use the same open-source engines as professional desktop software, compiled to WebAssembly: FFmpeg for video and audio, MozJPEG, libwebp and libavif for images, pdf.js and pdf-lib for PDFs, and libarchive for archives.
How to choose the right format
For photos on websites, WebP and AVIF give the smallest files. For maximum compatibility, use JPG for photos and PNG for screenshots, logos and anything with transparency. For video, MP4 with H.264 plays on every phone, browser and TV. For audio, MP3 is the universal choice, and FLAC or WAV keep full quality for editing.
For documents you want to edit, use DOCX. For documents you want to send or print exactly as they look, use PDF. For ebooks, EPUB works on almost every reader, including Apple Books, Kobo and Kindle through Send to Kindle.
Batch conversion and limits
Most converters accept several files at once and let you download them one by one or together as a ZIP file. There is no daily limit and no watermark. The only limit is your device's memory: phones handle files of a few hundred megabytes, and computers can handle several gigabytes.
Frequently asked questions
Are these file converters really free?
Yes. Every converter is free to use with no account, no watermark, and no limit on the number of files. Because the conversion runs on your device, there are no server costs to pass on to you.
Do I need to install anything?
No. The converters work in current versions of Chrome, Edge, Firefox and Safari on Windows, macOS, Linux, Android and iOS. The code loads with the page, and there are no extensions or apps to install.
Is it safe to convert private files?
Yes. Files never leave your device, so nobody else can see them. You can even disconnect from the internet after the page loads and the converters will keep working.
Why is video conversion slower than images?
Video has to be decoded and encoded frame by frame. In the browser, FFmpeg runs as WebAssembly on your device's processor, which is slower than a native app. Short clips take seconds, and long videos can take several minutes.
Which converter should I use if my format is not listed?
Start with the general converter for the file type, such as the Image Converter, Video Converter, Audio Converter, Document Converter or Archive Converter. They accept the widest range of input formats.
