How does compression work?

Each image is drawn to a canvas and re-encoded at the chosen quality — for JPEG and WebP that's real quality-controlled compression.

No. Every image is processed locally and zipped in your browser.

What's the size limit?

The main limit is browser memory. Hundreds of average-sized photos work; multi-hundred-MB batches may struggle.
