PNG does not use the quality setting. PNG/WebP preserve transparency; JPG uses the selected background. Re-encoding removes metadata and may increase file size. Check the preview and size.
How to use

Convert still JPG, PNG and WebP images. PNG/WebP preserve transparency; JPG uses your selected background color. Output names include sequence numbers and the correct extension.
Supports still JPG, PNG and WebP only, not GIF, animated PNG/WebP, HEIC or SVG. Up to 10 MiB each, 10 files, 50 MiB for inputs and outputs each, 24 million pixels and 16,384 pixels per side per image, and 60 million pixels combined. Images are re-encoded after applying EXIF orientation; metadata is not retained. Encoding results may vary by browser.
Processing runs in a separate worker and stops after 30 seconds. Editing inputs or options clears previous results. Limits raise errors instead of truncating files.
