Frequently asked questions

What happens to transparent areas in my PNG?

They turn solid white — standard 24-bit BMP has no alpha channel, so the canvas is filled white before your image is drawn on top.

Why is the BMP file so much larger than the PNG?

BMP stores pixel data uncompressed, so file size scales directly with image dimensions — there's no compression algorithm shrinking it the way PNG's does.

Is the conversion done on a server?

No — the BMP is built directly from the canvas's raw pixel data in your browser; nothing is uploaded.
