Questions
Is my image uploaded anywhere?
No. Conversion runs entirely in your browser on the Canvas API — the file never leaves your machine.
Why is my JPG smaller than the PNG?
JPG uses lossy compression and drops transparency, so it is usually much smaller. PNG and WebP keep an alpha channel.
What is the file size limit?
There is no server limit since nothing is uploaded; very large images are bounded only by your browser memory.
