Frequently Asked Questions

Does converting to PNG improve quality?

No. Detail that JPG compression removed cannot come back. PNG only stops more detail from being lost the next time you save.

Why is the PNG so much bigger?

PNG stores every pixel without lossy compression. A phone photo is often two to five times larger as PNG.

Will the PNG have a transparent background?

Not by itself, because a JPG has no transparency to keep. Use Remove background to make the background transparent.

Is the quality slider used?

No. PNG is always lossless, so only the size settings change the result.
