Make your file fit.
A form rejected your image? Put it in here and find out which rule it breaks: file size, format, or pixels. Then resize, convert or compress it to fit.

How it works
Pick the file a website rejected
It opens in your browser. Nothing is sent anywhere.
Type in what the upload page asked for
A maximum size, a format, a width or height. Whatever you were told.
See what doesn’t match, then fix it
Filnixa says which rule the file breaks and by how much, then resizes, converts or compresses it and checks the result.
The whole thing runs in your browser. The fixed file is written on your own device and downloaded straight from there.
Where your file goes
Nowhere. The whole check runs on your device.
- Your file is opened by your own browser. It is never sent to Filnixa.
- There is no account, and no record is kept of the files you check.
- Remove or replace a file and the browser copy is released straight away.
