About compressing an image
Image compression reduces a photo's file size for faster uploads, email, or web use, by lowering quality slightly and stripping metadata. A well-compressed JPG is often a fraction of the original with no visible difference.
The re-encoding happens on a canvas in your browser at the quality level you choose, and the smaller image downloads directly. The original never leaves your device, and you can compare before and after before saving.
How to Compress Image
- 1
Add your image
Drop in a JPG, PNG or WebP — it is decoded in your browser, never uploaded.
- 2
Choose how much to shrink
Drag the quality slider, or type a target size in KB and the tool finds the quality that fits.
- 3
Download
Save the smaller image — the before/after size is shown.

Compress Image — frequently asked questions
Does compressing an image lose quality?+
JPEG and WebP compression is lossy, so there is some quality loss — but at 60–80% quality it is usually invisible while the file shrinks a lot. PNG stays lossless.
Can I compress to an exact file size?+
Yes. Enter a target in KB and the tool binary-searches the quality (and downscales if needed) to land at or just under it.
Is my image uploaded?+
No. The image is decoded and re-encoded with a <canvas> in your browser. It never leaves your device.
What formats are supported?+
JPG, PNG, WebP, plus HEIC/HEIF and TIFF as input.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
