About PixDesk

PixDesk is a set of image tools that run in your browser. Drop photos on the mat, choose what should happen to them, and save the result.

Nothing is uploaded

Your files are opened and processed by this browser, on your device. They are never sent anywhere: PixDesk has no server that could take them. Close the tab and they’re gone.

What it costs

The tools are free, up to 20 files at a time. There are no accounts and no ads. A one-time Pro upgrade is coming, for more than 20 photos at once, every film look and saved presets.

Readers it may download

Some browsers can’t read every format on their own. When that happens PixDesk downloads a reader from this site, once, and says so with its size. Today that is the HEIC reader for iPhone photos, which Safari doesn’t need.

Who makes it

PixDesk is made by Pentarab, an independent software maker in Seoul.
