BMP to PNG — frequently asked questions

Is the file uploaded?+

No — the BMP is decoded and re-encoded as PNG entirely in your browser.

Any quality loss?+

No, PNG is lossless.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
