Image Compressor
Shrink JPG, PNG and WebP file sizes right in your browser.
🔒 100% browser-based — your data never leaves your device.
About this tool
Compress photos and images without installing anything and without uploading them anywhere. Pick an image, adjust the quality slider, and download a much smaller JPG or WebP — typical photos shrink by 60–90% with barely visible quality loss.
Smaller images load faster on websites, pass email attachment limits, and fit upload caps on forms and marketplaces. Because compression runs locally with the HTML5 canvas, even private photos are safe to use here.
Frequently asked questions
Is my image uploaded to a server?
No. The image is read and re-encoded entirely inside your browser using the canvas API. It never leaves your device.
Which quality setting should I use?
For photos, 0.7–0.8 is usually the sweet spot: a large size reduction with no visible difference. Go lower only if file size matters more than fine detail.
Why does my PNG become a JPG or WebP?
PNG is lossless, so real size savings come from converting to a lossy format. Choose WebP for the best compression, or JPG for maximum compatibility.
