BMP to PNG

Convert BMP to PNG for free in your browser. Batch-friendly and private. No upload, no sign-up, no watermark.

BMP is the uncompressed Windows bitmap format. Every pixel is stored as-is, so files are very large, but some older programs and devices still require it. PNG is a lossless image format that supports transparency. It’s ideal for screenshots, logos and graphics with sharp edges, but photos saved as PNG are large.

Converting to PNG keeps every pixel exactly (lossless) and preserves transparency – best for editing, screenshots and graphics. The conversion happens entirely in your browser, so your files are never uploaded and there’s no size limit beyond your device’s memory.

How to convert BMP to PNG

  1. Add one or more BMP files.
  2. They’re converted to PNG automatically.
  3. Download them individually or as a ZIP.
