Free file tools that never upload your files
Every tool on File Cabin runs entirely inside your browser. Your images are processed on your own device — nothing is uploaded, nothing is stored on a server, and there is no sign-up.

Most online converters upload your file to a server, process it there, and send it back. That means your photos travel across the internet and sit on someone else's disk — even for a one-second job.
File Cabin takes the opposite approach. The tool is downloaded to your browser once; the file you pick never leaves your computer. It is faster (no upload wait), more private (there is nothing on our side to leak), and it keeps working while the page is open even if your connection drops.
Faster
No upload wait — processing starts the moment the page opens, right on your device.
Private
Your files never leave your computer. There is nothing on our side to leak.
Free forever
No servers doing the work means no cost per file — no account, no watermark, no daily limit.
