How to convert BMP to PNG
Transform your BMP images into PNG in seconds. Everything runs in your browser — no file ever leaves your device.
Almost always — convert to any other modern format (PNG or JPG). You need transparency, exact quality, or are working with graphics or screenshots.
What is BMP?
Windows-native bitmap format, uncompressed (or minimally so). Each pixel is stored individually, producing huge files. Obsolete for web and mobile today, still shows up in some Windows workflows and legacy devices.
- Compatibility with old Windows applications
- Very old print pipelines that require BMP
- Cases where you need exact pixels with zero compression
Why convert to PNG
A lossless-compressed image format created in 1996 as a free alternative to GIF. Supports per-pixel transparency through an alpha channel, keeps exact quality, and is the standard for graphics, icons, screenshots, and any image with text or flat color areas.
- Images with transparency (logos, icons)
- Screenshots and screen captures
- Graphics, diagrams, infographics with text
- Material that will be edited multiple times (quality preserved)
Step-by-step: convert your image
1. Upload the file
Drag your BMP file into the upload area, or click to select it from your computer. You can upload several files at once — they'll be converted in batch.
2. Check the quality setting
PNG has adjustable quality in most cases. Leave it at 85-90% for the best size/quality balance. For professional material, bump it to 95-100%.
3. Click convert and download
Processing is near-instant (seconds per image) because it happens right in your browser. When it's done, download each file individually or all together as a ZIP.
BMP vs PNG: technical comparison
Before converting, it's worth understanding what each format brings to the table:
BMP — best for:
- Compatibility with old Windows applications
- Very old print pipelines that require BMP
- Cases where you need exact pixels with zero compression
BMP — limitations:
- Massive file size (10-50× larger than JPG)
- No transparency support by default
- Inefficient for anything modern
PNG — best for:
- Images with transparency (logos, icons)
- Screenshots and screen captures
- Graphics, diagrams, infographics with text
- Material that will be edited multiple times (quality preserved)
PNG — limitations:
- Files significantly larger than JPG or WebP
- Not ideal for photos (less efficient compression)
- No animation support (use APNG or GIF)
When converting from BMP to PNG makes sense
Typical scenarios where this conversion solves a real problem:
- Compatibility with old Windows applications
- Very old print pipelines that require BMP
- Images with transparency (logos, icons)
- Screenshots and screen captures
