Privacy

UnderKb is a no-account image tool. We do not create user profiles, and we do not keep a gallery of the photos you drop.

What we process

When you upload a file we decode it on this server, run the job you asked for (compress, convert, resize, flat-background cut, or palette), and keep the result in memory about 30 minutes so you can download it. Then it expires.

Rate limits use your IP for a short window so the 512 MB machine is not flooded. Optional Pro keys are checked from a header or a cookie you stored after opening ?key=. We do not sell a list of your files.

What we do not do

No sign-up, no mailing list, no stored library. Use the tools on images you are allowed to process. We are not affiliated with Google, Adobe, or the camera brands.

Advertising

Reserved ad slots may show Google AdSense when a publisher id is configured. Google and its partners may set cookies or use similar identifiers. See Google’s advertising policies and Ad Settings. Publisher ads.txt is served at /ads.txt when a publisher id is configured.

Browser extension

The optional Chrome extension only opens this website. It does not show Google AdSense inside the popup. Ads stay on these pages.

Analytics

If GA4_ID or PLAUSIBLE_DOMAIN is set on the server, page views are measured so we can see which landings work. No account on this site either way.

Contact

Questions: open an issue on GitHub (set CONTACT_EMAIL on the server to show a mailbox). Terms · Pro.
