FAQ

Does this remove metadata (EXIF)?

Yes. When the browser re-encodes the image onto a canvas to convert it, metadata like GPS location, camera model, and date taken are automatically stripped. This is great for privacy.

Why did my PNG size increase?

If you convert a highly compressed JPG to PNG, the file size will grow significantly. PNG is lossless, meaning it saves every pixel perfectly, whereas JPG discards invisible data to save space. Only use PNG if you need transparency or sharp text.
