Convert BMP to PNG in your browser: lossless like BMP, but compressed and web-friendly. PNG preserves every pixel exactly while shrinking the file to a fraction of the BMP size. Use it for screenshots, pixel art, diagrams, and logos where accuracy matters more than JPG's photographic compression. No upload.

Common questions
Is it lossless?+
Yes — PNG preserves the BMP exactly, pixel for pixel, just with compression applied.
Why PNG instead of JPG?+
Use PNG for pixel-perfect output (graphics, text, screenshots). Use JPG when file size matters most and the image is a photograph.
Uploaded anywhere?+
No — fully in-browser conversion.
When should I pick BMP-to-PNG over BMP-to-JPG?+
Choose PNG when pixel accuracy matters (graphics, logos, screenshots with text). Choose JPG when file size matters most and the image is photographic.
