Local File Utilities. No Uploads. Instant Results.

There's no limit set by us. Since everything happens on your own device, the only real ceiling is how much your computer or phone can comfortably handle — very large files might run a little slower on older devices, the same way any big file would in any other app.

Most online tools make you upload your file, wait in a queue, and hope it comes back correctly — and for a few minutes, your file is sitting on someone else's server. FormatGrid skips all of that. Your file never leaves your device, so there's no wait and nothing to worry about.

Nope. Just open the tool you need and start — no account, no download, no browser extension. It works the moment you land on the page.

PDF, image, and audio tools are all available today — merge, sign, edit, compress, convert, trim, and more — with new tools added regularly. Every tool we add follows the same rule: your file stays on your device, no uploads, ever.
