Your files never leave your device.
CompressGo runs entirely inside your browser using modern Web APIs. No backend touches your documents — there is no upload to intercept, no server log to leak. Use it for invoices, contracts, ID scans, family photos, anything you would not hand to a stranger.
Built for people who don't want to upload their files
CompressGo works differently from most online tools. Here is exactly what that means for you.
Your files never get uploaded
Every tool runs inside your browser tab using the browser's own image, PDF and archive APIs. Nothing is sent to a server, so there is no copy of your file anywhere but your own device.
It keeps working offline
Once a tool page has loaded, you can disconnect from the internet and it still compresses and converts. Useful on a plane, on mobile data, or on a locked-down office network.
No account, no email
There is no sign-up wall and no verification step. Open the page, drop a file, get the result. We do not ask who you are because we do not need to know.
Nothing is stored afterwards
There is no queue, no temporary server folder and no 'files deleted after 1 hour' promise to trust. When you close the tab, the file is gone from memory.
As fast as your own machine
There is no upload wait and no download wait. Compression speed depends on your device, which for most files means results in a second or two.
No daily limits or paywalls
Because we are not paying for server processing, there is nothing to meter. Compress one file or two hundred, in one sitting, at no cost.
