What AllThatConverter is
Changing a file format or shrinking a large file is something we all need to do, but installing a heavy desktop app every time is a hassle. AllThatConverter is a free toolkit that lets you finish those jobs in a few clicks in your browser. No install, no signup — open the site and use what you need.
Above all, we put a safe approach that never sends your files to an external server first. Every conversion and edit runs on your device (in the browser), so work docs and personal photos never travel over the internet. When you are done, the result stays only on your device.
If you cannot find the conversion you need, please contact us. We keep adding useful tools based on your feedback.

Frequently Asked Questions (FAQ)
Yes. Every tool — 90+ of them — is free to use, with no account or login required.
Absolutely not. Every single conversion and media processing engine operates strictly inside your browser's secure isolated sandbox. Your file data never leaves your computer or mobile device and is immediately purged from RAM upon tab closure.
By default, our tools apply lossless or master-quality encoding presets to preserve maximal visual and acoustic fidelity. You can also manually fine-tune resolution, compression quality, and bitrates according to your needs.
There is no artificial daily quota or file-count paywall. Processing runs in your browser’s memory (RAM), so the practical limit is what your device can handle at once. For very large jobs, split batches into groups of about 10–20 files.
Yes! The platform is fully responsive and optimized for touch interactions across mobile Safari, Chrome, Samsung Internet, and in-app webviews (KakaoTalk, Line, Naver, Instagram).
Yes. You may use it for company reports, YouTube or client deliverables, software development, and other personal or commercial work, with no attribution requirement on the outputs.
No app or browser extension install is required. Open the site in any modern browser on PC, tablet, or phone and start immediately.
For extremely large media files (multiple gigabytes), your browser may temporarily run low on RAM. We recommend closing unused browser tabs or splitting large batches into smaller groups of 10–20 files.
Certain in-app webviews (such as Instagram, Threads, TikTok, or KakaoTalk) enforce strict sandboxing policies that block direct file downloads. AllThatConverter automatically detects in-app environments and provides guidance. Simply tap the menu icon (⋮ or Share) in your app and select 'Open in Default Browser' (Chrome, Safari, etc.) to convert and download files smoothly.
