Frequently asked questions
Can I convert multiple images at once?
This tool accepts one image at a time, up to 5 MB. The output is a data URL rather than a batch of image files.
Does Base64 compress an image?
No. Base64 generally expands the encoded bytes by about one third, plus the short data URL prefix.
