BMP to PNG: Modernize Legacy Images

BMP files show up in older Windows workflows, exports from legacy software, and certain scanners. The format is simple, but it is not ideal for modern sharing and web use.

PNG is a better modern replacement: widely supported, lossless, and friendly to editing workflows.

Use: BMP to PNG.

When to convert BMP to PNG

Convert BMP to PNG when:

• You want a lossless format that “just works” across modern apps
• You are putting images on the web
• You plan to edit the image and want predictable results

If file size is your top priority (especially for photos), JPG may be better:

• BMP to JPG

PNG vs BMP: what changes?

From a “pixels” standpoint, you are keeping the same image content, but PNG gives you practical benefits:

• Much better compression than BMP in most cases
• Better compatibility across modern devices and tools
• Support for transparency (if your source image has it)

For document-like images and graphics, PNG is a strong default.

Common BMP issues you can fix by converting

BMP itself isn’t “bad”, it’s just old. Converting to PNG helps when you run into:

• Huge files that are annoying to email or upload
• Apps that won’t preview BMP reliably
• Workflows where you need transparency or clean edits

If you’re converting a photo-like BMP and file size matters more than losslessness, JPG can be the better delivery format:

• BMP to JPG

If you’re converting for the web

PNG is widely supported, but it’s not always the smallest. A good modern workflow is:

1. Convert BMP to PNG for compatibility and clean editing.
2. If you need smaller files for your website, convert PNG to WebP:
   • PNG to WebP

If you’re sharing files directly with people or uploading to unknown systems, PNG is still the most predictable output.

FAQ

• Is PNG always smaller than BMP? Often yes, but not always. PNG compression is usually much more efficient than BMP, especially for large images.
• Can I batch convert multiple BMP files? Yes. You can convert up to 20 files at a time and download the results.
• Should I use WebP instead of PNG? For websites you control, WebP can be smaller. For broad compatibility and editing workflows, PNG is a safer default.
• Is this conversion private? Yes. QuickImager runs locally in your browser and does not upload your files.
