Frequently asked questions
Are my images uploaded?
No. Your images stay on your device and are processed by your browser. They are never uploaded to a server, and you do not need an account.
Does PNG preserve transparency?
Yes. PNG keeps transparent areas and saves the decoded image without further lossy compression. It cannot restore detail already lost in the original. Conversion may change color profiles, bit depth or metadata, so original HDR and photo details are not guaranteed to be kept.
Which files can I convert?
Use static images: up to 20 files per batch, 20 MiB per file, 25 megapixels and 10,000 pixels per dimension. Animated and multi-frame images are not supported. Files are checked by their contents, not just their names.
