About BMP to PNG conversion

PNG (Portable Network Graphics) uses lossless compression, meaning no image quality is lost during conversion. Unlike JPEG, PNG perfectly preserves sharp edges, text, and transparency. Converting BMP to PNG typically reduces file size by 50-80% while maintaining perfect quality.

When to convert BMP to PNG

You need smaller files but cannot accept any quality loss. PNG is ideal for screenshots, diagrams, logos, and images with text where JPEG artifacts would be visible.

This tool converts your BMP to PNG with optimal compression. The resulting file will be smaller than the original BMP while looking exactly the same.

For photos where some quality loss is acceptable, JPEG will produce smaller files. But for graphics, screenshots, or images with transparency, PNG is the better choice.

Frequently asked questions

How much smaller will my PNG file be?
Typically 50-80% smaller than the original BMP, depending on image content. Images with large areas of solid color compress better.
Is there any quality loss?
No, PNG uses lossless compression. Your converted image will look exactly like the original BMP, pixel for pixel.
Should I choose PNG or JPEG?
Choose PNG for screenshots, graphics, logos, or images with text. Choose JPEG for photos where smaller file size matters more than perfect quality.
Does PNG support transparency?
Yes, PNG supports full alpha transparency. If your BMP has no transparency, the PNG will simply have a solid background.
Is my file stored on your servers?
Files are kept only long enough for you to download the result. Everything is automatically deleted within 24 hours. We do not store, share, or analyze your images.
