Why convert BMP to PNG?

PNG compresses BMP images without losing a single pixel of quality. You get the same perfect image in a much smaller package. PNG is also far more compatible with modern apps, websites, and design tools than BMP.

Common reasons people convert BMP to PNG:

  • Compressing BMP files without any loss of image detail
  • Converting old BMP images to a modern, compatible format
  • Making BMP files work on websites and design tools
Privacy guarantee: When you convert images here, your files never get sent to any server. The entire process runs in your browser — on your own device. No API is used, no data is collected, nothing is stored. It is the safest way to convert images online.

About BMP files

BMP stands for Bitmap. It is one of the oldest image formats and stores images without any compression. Every single pixel is saved exactly as it is, which creates very large file sizes.

What BMP is good for: BMP images have zero quality loss. They are simple for software to read and write. Most Windows programs can open BMP files without any trouble.

Where BMP falls short: BMP files are massive in size. A simple photo saved as BMP can be 10 to 20 times larger than the same image saved as JPEG. This makes BMP files hard to share by email or upload to websites.

When to use BMP: BMP is rarely the right choice for sharing or storing images. If you have a BMP file, convert it to JPEG, PNG, or WebP to get a much smaller file that is easy to use anywhere.

About PNG files

PNG stands for Portable Network Graphics. It saves every pixel of your image exactly as it is, without any quality loss. PNG files can also have transparent backgrounds, which makes them popular for logos and graphics.

What PNG is good for: PNG gives you perfect image quality every time. You can save it over and over without losing any detail. Transparent backgrounds work great for logos, stickers, and icons that need to sit on different colored backgrounds.

Where PNG falls short: PNG files are usually much larger than JPEG files. For photos with millions of colors, the file size can be very big, which slows down websites and takes up more storage space.

When to use PNG: Use PNG for logos, icons, text images, and any graphic that needs a transparent background. It is also great when you need to keep every single detail of an image for editing.
