About Image Compressor
Working with images online usually means uploading them to a stranger's server and hoping for the best. Image Compressor avoids that entirely. Compress JPG, PNG and WebP images right in your browser — no upload, no quality loss.
Your images are processed locally in the browser using the Canvas API. Nothing is uploaded, nothing is stored, and you can drop in private photos, screenshots or design mockups with confidence.

Frequently asked questions
Are my images uploaded anywhere?
No. Images are processed in your browser using the Canvas API and never leave your device.
What formats does Image Compressor support?
All common web image formats — JPG, PNG and WebP — and SVG where relevant.
Is there a file-size limit?
There's no hard cap, but very large images may use a lot of memory. Try compressing first if needed.
