Vergleich der Dateiformate BMP und PNG.

BMP und PNG sind Dateiformate für Bilder von hoher Qualität. Während BMP-Dateien unkomprimierte Rohdaten enthalten, lassen sich PNG-Dateien in kleinere, handlichere Größen komprimieren. Hier erfährst du mehr zu den wichtigsten Unterschieden zwischen BMP und PNG.

Was ist eine BMP-Datei?

BMP ist die Abkürzung für Bitmap, ein universelles Dateiformat, in dem Bilder auf allen Geräten exakt dargestellt werden. BMP-Dateien gewährleisten hohe Bildqualität und Detailgenauigkeit. Jedes einzelne Pixel wird als separate Einheit behandelt. Deshalb sind die meisten BMP-Dateien relativ groß, lassen sich aber auch einfacher bearbeiten.

Was ist eine PNG-Datei?

PNG steht für Portable Network Graphic. Das vielseitige Format wurde ursprünglich für die Bereitstellung und Weitergabe hochwertiger Bilder im Web entwickelt. PNG-Dateien werden bei der Speicherung verlustfrei komprimiert. Sie können ohne Qualitätseinbußen vergrößert und verkleinert werden. PNG ist zwar weniger verbreitet als andere Dateiformate, wird aber gerne von Grafik-Designern verwendet.

What is the difference between BMP and PNG files?

BMP and PNG files have a lot in common. They’re both raster file types that were developed and released the same year. The major difference is in their compression.


BMP files are uncompressed and lossless. They’re large files that retain as much detail as possible. PNG files, on the other hand, are compressed and lossless. When you reduce or expand PNGs, you don’t lose any information. Their smaller file size and compression capabilities can make PNGs easier to use.


Discover some of the other differences between BMP and PNG files.


A truer image. 

BMP files are sometimes known as “true images” because they render each individual pixel within the file. They don’t compress automatically. This makes them large — a collection of BMP files will rapidly consume lots of memory and space. 


PNG files display high-quality images, but unlike BMPs, they use compression. They work well for simple graphics like icons, logos, line drawings, comic strips, and embedded graphics.


File size.

Given the same image or content, BMP files will be larger than PNG files. Both retain as much detail and information as possible, but PNG files automatically compress — and can be compressed again to make the file even smaller. Because of the way they handle individual pixels, BMP files have dimensional restraints, maxing out at 4GB.


Common uses.

BMPs store high-quality images with a maximum amount of detail. When they first launched, this made them ideal for editing. Later file types have surpassed BMP for editing use cases, so today most people use BMP files for storage.


The original purpose of PNG files was to move images around the web. A staple of many websites, they’re a good file type for small illustrations, sketches, drawings, logos, and icons. Graphic designers often use PNGs for stand-alone graphics.


It’s particularly easy to use transparency in PNGs when there’s a singular subject with defined borders and a large block of surrounding space, like a logo or icon. This allows graphic designers to use them, both with layers and as layers, when rendering backgrounds.



Both BMP and PNG files are lossless file formats. This means after compression, you can restore either file type to its full original quality.


BMPs use a simple algorithm to efficiently compress images into small sizes. PNG files compress quickly to small file sizes — plus, you can compress them multiple times.



BMP files have slightly higher quality due to how they handle pixels and their raw format. However, there's not much difference in the quality between BMP and PNG files.



Neither BMP nor PNG files are good choices for printing because both have limitations with physical paper and ink. They especially struggle with the CMYK (cyan, magenta, yellow, key/black) color scale.



BMP vs. PNG files: frequently asked questions.

What programs open BMP files?

BMP files are compatible with a wide range of operating systems and design programs, including Adobe Photoshop and Adobe Illustrator.


Are BMP files bigger than PNGs?

If both files contain an identical image, BMP files will be slightly larger. But because of their fixed dimensions, BMP files generally won’t exceed 4GB in size. There is no size limit to a PNG — they can easily be 140GB or larger.


Is there a difference in how BMP and PNG files treat color?

Both are about the same. They can assign approximately 16,777,216 different colors to pixels. At the same time, BMP files are more efficient with smaller, more limited palettes. Both image types work well in black and white.


Are BMP or PNG files more useful?

BMP files are becoming increasingly less common than PNG files. While BMP files are high-quality and easy to edit (especially with Microsoft programs), other image file types have become more popular for editing and storage. You can use PNG files for high quality images and small, simple designs, plus they’re especially useful for displaying images on the internet.
