PRO TIPS
Get the Best Results
Use 70–80% for Photos
JPEG at 75% is virtually indistinguishable from 100% to the human eye but cuts file size by 60–70%.
Choose WebP for Web
WebP provides 25–35% smaller files than JPEG at equivalent quality. Supported by all modern browsers.
PNG for Transparency
Use PNG output when your image has a transparent background — JPEG doesn't support transparency.
Max Resolution 1920px
Images wider than 1920px are resized proportionally. This alone can reduce file size dramatically.
GOT QUESTIONS?

Frequently Asked Questions

No. All compression happens entirely in your browser using the Canvas API. Your images never leave your device.
70–80% is ideal for most use cases. Below 50% you'll notice visible quality loss. For web thumbnails, 70% is perfect.
JPEG is best for photos and gives the smallest file sizes. PNG is lossless and supports transparency. WebP offers the best of both — small size and transparency support — for modern browsers.
There's no hard limit. Practically, your browser's memory sets the ceiling. Dozens of images work fine; hundreds may slow your browser.
