How much can I compress an image without losing quality?

For JPEG and WebP, 80–90% quality usually cuts file size by 40–70% with no visible difference. Below 60% you'll start to notice artifacts on detailed images.

Is my image uploaded to a server?

No. Compression happens entirely in your browser using the Canvas API. Your file never leaves your device.

Which format compresses best — JPEG, PNG, or WebP?

WebP typically produces the smallest files at equivalent quality. JPEG is a close second for photos. PNG is lossless so it compresses less but preserves transparency and sharp edges.

Can I compress PNG images?

Yes. PNG compression here re-encodes the image; since PNG is lossless, size reduction is smaller than JPEG/WebP but there's no quality loss.
