Compression mode
Downscale to 1600px max width, then compress as JPEG.
What makes this useful
Quickly reducing upload sizes for forms, blogs, and design handoff.
Testing whether WebP or JPEG gives the better tradeoff for a given image.
Combining width limits with compression in one step saves repeated re-exports.
Practical notes
PNG output is lossless, so the quality slider only matters for JPEG and WebP.
Large transparent PNGs often compress better after converting to WebP.
Everything happens locally, so private drafts and client assets stay on-device.
