Shrink a photo to the exact size a form asks for.
Pick a target — 20 KB for an exam form, 200 KB for a marketplace listing — and PhotoToolKit gets your image there without leaving your device.

How it works
01
Add your photo
Drag a JPG, PNG or WebP file in, or tap to choose one from your phone or computer.
02
Choose a target size
Pick a preset like 20 KB or 200 KB, or type any custom size in kilobytes.
03
Download the result
See the new size and percentage saved, then download — nothing is kept or stored.
Built to keep your photos private
Runs entirely in your browser
Compression happens on your own device using the canvas built into your browser. Your image is never sent to a server.
Nothing is stored
There is no account, no upload history, and no database of images — closing the tab clears everything.
Fast, even offline-ready
Because there is no upload or download round-trip, compressing a photo takes moments, even on a slow connection.
Common uses
