Built differently

The useful part, without the usual tradeoffs.

01 · Privacy

Private by architecture.

Your file is read and transformed by code on your device. There is no file-processing server to trust.

POST /upload0 requests

02 · Access

No account wall.

Open a tool, finish the task, and download the result. Core tools are free and require no identity.

0forms before your file

03 · Limits

No artificial upload caps.

We do not meter file uploads because files are not uploaded. Your device and each format set the practical boundary.

~~Max file size: 25 MB~~your device decides

04 · Offline

Keep working when the signal drops.

After a tool and its processing assets load once, FileGizmo caches them on this device so the same workflow can run without a connection.

Try the claim

Disconnect the internet. Watch it still work.

Open a tool once while online, then switch off Wi-Fi or mobile data and reload it. A cached workflow keeps processing on this device because there is no conversion server to reach.

01Open Word counter while connected.
02Wait for the page to load, then disconnect.
03Reload, type a sentence, and watch the count update.

First use needs a connection. Tools with large processing engines or models need those assets loaded once too. Clearing FileGizmo site data removes the cached copy.

Your files.Nowhere else.
