Your files

Modern phone photos run 4โ€“12 MB each โ€” three attachments and Gmail refuses to send. This preset resizes to 2048 px (plenty for viewing on any screen) at ~500 KB each, so a dozen photos travel in one email. Drop them all at once; each is compressed in your browser.

How it works

  1. Check the target. This page is preset for the spec above โ€” adjust any number to match your exact form.
  2. Drop your photo. ExactKB finds the best quality and dimensions that land inside the size window โ€” including padding files up when a form has a minimum size.
  3. Download. The file fits the requirement on the first try.

FAQ

Will the recipient notice quality loss?

On screen, no โ€” 2048 px at high JPEG quality looks identical in an email client. For print-quality originals, send full files via a link instead.

Is my photo uploaded to a server?

No. ExactKB runs entirely in your browser. Your file never leaves your device โ€” this page even works offline.
