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.

01
Open Word counter while connected.
02
Wait for the page to load, then disconnect.
03
Reload, 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.

Don’t trust us? Open your network tab and watch.

No ceremony

Drop a file. That’s it.
