Can I make an image larger without it blurring?

Enlarging always softens detail because the extra pixels have to be invented. Staying under about 150% of the original size keeps the result acceptable.

Which format does the resized image use?

By default it keeps the original format. You can switch the output format on the Convert image tool if you need something different.

Is there a maximum resolution?

Browsers cap canvas sizes at very large dimensions, so extremely big images may be limited. Anything up to normal camera resolutions works fine.
