canvas.toDataURL(type, encoderOptions);

MDN\'s description about the type parameter says the following:

type

Answer 1

Per the firefox source code, they seems to support:

• png
• jpeg
• ico
• bmp

Chrome per the source code, should support:

• webp
• png
• jpeg
• bmp

Internet explorer modern versions, should be alike to Firefox(crossing fingers).

If I need to vote the "per today" available options, I will go with: PNG, JPEG, and BMP

Quality influences options:

• JPEG, quality percent, where 0 is 0%, 0.5 is 50% and 1 is 100%
• BMP, BPP, bytes per pixel (thanks to @apsillers for pointing out)
