Frequently Asked Questions
Will converting to PNG improve quality?
No. JPEG compression is already lossy, so PNG preserves what is there but cannot restore detail that was discarded. It does prevent further loss on re-saves.
Are the dimensions preserved?
Yes. The output is pixel-for-pixel the same size as the input.
Will the file get bigger?
Usually yes, because PNG is lossless. The before and after sizes are both shown so there is no surprise.
