How do I balance quality and file size?

Use the quality slider for JPG/WebP: lower values shrink files but may introduce blocky artifacts. PNG size is reduced mainly through palette optimization and encoding options.

Can I batch compress and convert formats?

Yes. Import multiple images, apply compression settings individually or in bulk, convert between PNG/JPG/WebP, and download the results together.

Is EXIF metadata kept after compression?

Re-encoding usually strips EXIF such as GPS and camera info, which further reduces file size and avoids leaking sensitive metadata.
