Two formats

What you bring, what you leave with.

Source.bmp

BMP

BMP is an uncompressed 24-bit Windows bitmap format. Files are large but pixel-perfect and trivial for any image library to read.

Target.png

PNG

PNG is a lossless raster format with full alpha transparency. Best for screenshots, logos, and graphics where you can't afford any quality loss.

On the matter

Why convert BMP to PNG.

PNG is lossless and supports full alpha transparency. Converting BMP to PNG is the right move when you need pixel-perfect quality, transparent backgrounds, or compatibility with design tools, documentation, and chat apps that strip metadata from other formats.

The procedure.

  1. 01Open this page in any modern browser.
  2. 02Drop a .bmp file onto the zone above, or click to pick.
  3. 03Adjust quality if needed.
  4. 04Download your .png. Nothing is uploaded.

Letters to the editor.

Q.01How do I convert BMP to PNG?+
A.01

Drop your BMP file onto the converter above (or click to pick one), then hit Convert. Your PNG download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.

Q.02Is converting BMP to PNG lossless?+
A.02

Yes. PNG is a lossless format, so the conversion preserves every pixel of your BMP after decoding. If the source BMP was lossy, the file is already at its source quality and won't degrade further.

Q.03Will my BMP files be uploaded to a server?+
A.03

No. Pixelmint runs the entire conversion in your browser using the Canvas API. Your image bytes never touch our servers, which is why this is safe for confidential screenshots, IDs, and proprietary artwork.

Q.04Is there a file size limit?+
A.04

There's no hard limit, but very large images (over ~50 megapixels) can be slow on low-RAM devices because everything happens locally. Most browsers cap canvas size around 32,767 pixels per side.

Q.05Does it cost anything?+
A.05

No. BMP to PNG conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.
