BMP to PNG Converter, Free and In Your Browser
PNG compresses better than raw BMP while staying lossless, which helps when a vendor export must feed a PNG-only pipeline.
Upload a BMP below to download PNG at the same dimensions.
Format notes
When to use this output
BMP to PNG keeps lossless pixels while switching to a compressed container PNG tools understand. Useful when a vendor exports BMP but your pipeline expects PNG.
Transparency
Standard BMP is opaque. PNG written here is opaque unless the rare BMP carried alpha data the browser decodes.
Quality
PNG preserves the decoded bitmap without another lossy step. BMP artifacts, if any, remain unchanged.
File size
PNG uses deflate and is usually far smaller than BMP on disk, though still larger than JPG for photographic scans.
FAQ
Better than ZIP for BMP?
PNG is a single-file image format editors open directly; ZIP would still need unpacking.
Will 1-bit BMP scans stay sharp?
Line art should stay crisp in PNG. Check preview zoom for stray gray fringes.
Upload size limit?
25 MB per file and 8000 px per side, consistent with other converters here.
