Your files don’t leave your device
Your browser shows everything a page sends. Try it:
- Open a tool, then the developer tools (F12).
- Go to the Network tab.
- Process a file: its content appears in no request.
Exception: a few tools that need public online data (such as the elevation of a place) query an external service.
Frequently asked questions
Are my files really sent anywhere?
No. Conversions and compression run in your browser (JavaScript and WebAssembly): your files stay on your device and are never uploaded to a server, unless a tool's page explicitly says otherwise.
Do I need an account or to pay?
No. Every tool is free and works without signing up.
Which file types can I process?
Images (HEIC, JPG, PNG, WebP, AVIF, SVG), PDF, audio and video (MP3, WAV, MP4, MOV, GIF), data (JSON, CSV, XML, Excel), text, plus generators and security tools.
What file size is supported?
There is no server-side limit because nothing is uploaded: the limit depends on your device's memory. A recent browser (Chrome, Firefox, Safari or Edge) is recommended.
