Frequently asked questions
Does converting BMP to PNG lose quality?
No. PNG is a lossless format: the decoded pixels are stored exactly, so nothing beyond the original encoding is lost.
Is my file uploaded to a server?
No. This tool runs entirely in your browser. You can open your browser's network tab and verify no request carries your file.
What happens to the metadata?
Re-encoding through the browser produces a clean file: EXIF, GPS and C2PA metadata are not carried over to the output.
