Image Compressor
Shrink image file sizes without uploading them anywhere. Pick a photo, adjust the quality slider, optionally cap the width, and export a smaller JPEG or WebP — with a live before/after size comparison. Everything runs on your device using your browser's canvas, so your images stay private.

Frequently asked questions
Are my images uploaded to a server?
No. Compression happens entirely in your browser with the canvas API, so your images never leave your device.
Should I use JPEG or WebP?
WebP usually produces smaller files at the same quality and supports transparency, but JPEG has the widest compatibility. Try both and compare the resulting sizes.
Will compressing reduce image quality?
Lowering the quality slider trades some visual detail for a smaller file. The live preview lets you find the sweet spot where the image still looks good.
