graphkit.io — image compressor
Drop an image to compress
or browse files · JPG, PNG, WebP · max 50 MB

Runs entirely in your browser — files are only uploaded if you choose “Save to My Graphkit”.

How it works

01
Drop an image
JPG, PNG or WebP. It never leaves your device.
02
Tune quality
Choose JPEG or WebP and drag the slider — the size updates live.
03
Download
Get the optimized file and see exactly how much you saved.

Smaller images load faster and rank better. Graphkit re-encodes your image directly in the browser using the JPEG or WebP encoder built into your browser, so you can find the best balance between quality and file size without uploading anything.
