Frequently asked questions
Will my PNG transparency be preserved?
PNG output preserves transparency. You can also select WebP for a potentially smaller transparent image.
Why can lossless PNG remain large?
PNG is lossless, so its size may not respond to the quality slider. Reducing dimensions or choosing WebP can produce a larger reduction.
Are PNG files uploaded?
No. Decoding, resizing, and export happen on your device.
