Frequently Asked Questions
What format is the output?
The output is a PNG file. PNG supports alpha channels, so the semi-transparent effect is fully preserved.

You can upload any image format supported by your browser, including JPG, PNG, WebP, and GIF.
Are files uploaded to a server?
No. All processing happens entirely in your browser. Your files are never sent to any server.
