Frequently Asked Questions
Is my image secure and private?
Yes. The entire workflow occurs directly inside your browser window. No files are
uploaded to any server. You can even run the page completely offline.
Which output format is best?
For web applications, WebP offers the best compromise between visual compression and
file size. JPEG works universally but lacks transparency. PNG is recommended only for
diagrams or assets where crisp, lossless rendering is required.
Why does my PNG become larger when converting?
If you select PNG output, it will apply lossless processing. Since WebP and JPEG use
lossy compression, converting them back or forcing PNG output can result in larger file
footprints due to how pixel matrices are stored.
