Questions
Which file types can I use?
JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. Because decoding is handled by your browser rather than a conversion server, support tracks whatever your browser can already open.
Is there a file size limit?
No imposed limit — there is no server quota to hit. The real ceiling is your device's memory, since the whole file is held in RAM while it is processed. Desktop browsers cope with very large files; phones give up sooner.
What are the limits on corner radius?
It accepts 0 to 50%, starting at 12%.
