Tips

JPEG is best for photos — 70–85% quality is usually indistinguishable from the original
WebP produces smaller files than JPEG at the same quality for most images
WebP also supports transparency — useful for compressed versions of removed-bg images
For web use, aim for under 200 kB for hero images and under 100 kB for thumbnails

Frequently asked questions

What quality setting should I use?

For web use, 75–85 strikes the right balance — visually near-identical to the original but 30–70% smaller. Go lower only for thumbnails where file size matters more than fine detail.

Is WebP always better than JPEG?

WebP typically produces 25–35% smaller files than JPEG at the same perceptual quality. Use JPEG only if you need maximum compatibility with very old software or browsers.

What is the maximum image size I can compress?

There is no hard size limit — the canvas API processes whatever the browser can decode. Very large images (>20 MP) may take a few seconds on mobile devices.
