Why convert BMP to PNG?
Screenshots, diagrams and scanned documents saved as BMP need to shrink without losing a single pixel of sharpness. Converting to PNG applies lossless compression, cutting file size while keeping text and hard edges perfectly crisp.
Quality and transparency
PNG is lossless, so no visual detail is sacrificed, though the result is still noticeably lighter than the original BMP. Any transparency present in the source is fully preserved.
Frequently asked questions
Can I convert several BMP files at once?
Yes — drop as many files as you want and download them individually or as a single ZIP.
Can I convert PNG back to BMP?
Yes. The tool accepts JPG, PNG, WebP and AVIF as input, and you can pick any of them as the output format.
Is my photo uploaded anywhere?
No. Everything runs locally in your browser with WebAssembly — your image never leaves your device, which makes this safe even for ID photos and documents.
