Convert BMP to PNG — Lossless, Much Smaller
Turn uncompressed BMP bitmaps into lossless PNG files that are far smaller yet keep every pixel.
Drop files or click to upload
Supports JPG, PNG, WebP, AVIF, HEIC, PDF, and more. Paste (Ctrl+V) works too.
How Our Privacy Engine Works
When you drop an image onto VisualConvert, our code runs entirely inside your device's web browser using modern web standards (Canvas API & WebAssembly). Unlike traditional converters that upload your photos to remote servers, process them there, and send them back, VisualConvert processes everything locally in your computer's memory. You can verify this anytime: open your browser's Developer Tools (F12), switch to the Network tab, and drop a file — you will see zero upload requests!
About converting BMP to PNG
PNG uses lossless compression, so converting BMP to PNG keeps your image pixel-perfect while shrinking the file substantially compared to the raw bitmap. It is the best choice when you can't afford any quality loss.
VisualConvert re-encodes your bitmaps to PNG entirely in the browser. Transparency, if any, is preserved, and nothing is ever uploaded — ideal for archiving scans and graphics.

BMP to PNG — Frequently Asked Questions
Is PNG smaller than BMP?
Yes, significantly. PNG compresses losslessly, so it keeps identical quality at a fraction of the BMP size.
When should I pick PNG over JPG for a bitmap?
Choose PNG when you need lossless quality, sharp edges (like text or line art), or transparency.
Is the conversion private?
Completely. The bitmap is processed in your browser and never uploaded.
