Is Bitmap A Lossy Or Lossless Format?

Is Bitmap A Lossy Or Lossless Format?

When choosing which file type to use for uploading an image, chances are you will come to find Bitmap (BMP) files. You want to make sure your image retains as much quality as possible, and comparing file types is the best way to do this. One thing to consider is whether a file type is lossy or lossless. So, is bitmap a lossy or lossless format?

Bitmap is a lossless format and is an excellent file type for images, particularly of larger sizes. While BMP files may not typically contain initial features of other file types, BMP files can be altered to better suit your upload needs.

Continue reading to learn more about whether bitmap is a lossy or lossless format as well as other features that make it comparable to various file types. It might not be the best choice in every situation, but there are certainly benefits to using a BMP file.

Is Bitmap A Lossy Or Lossless Format?

Bitmap is a lossless format, making it great for storing large, high-quality images that stay the same when you upload the image. When a file type is lossless, it means that even details on the image that are otherwise unseen by the human eye remain a part of the image upon conversion.

When using an image for your graphic design endeavors, whether it be your preference or simply works better for your design, the ability to maintain the original image while converting and uploading may be essential. So, whenever you save an image as a BMP file, it will remain perfectly accurate upon uploading.

As you will learn shortly, bitmap files provide other attributes that make them useful for certain scenarios. A BMP file’s lossless format, however, is perhaps the most key aspect in making sure the image remains the same when you upload it for a graphic design project. 

Is Bitmap Compressed or Uncompressed?

One thing to note about BMP files is that they are preferred by those looking to save an exceedingly large image. Doing so is a huge advantage for bitmap files, although not everyone sees the attribute as necessary in all cases.

Typically, bitmap files are uncompressed, meaning that saving an image as a BMP file maintains its quality but prevents it from reducing the amount of digital information. This is useful for large images, but it subtracts from the amount of storage on your device more quickly than a compressed file type.

If a file type is compressed, the image will be rid of information that is not essential to the image itself. The file releases non-critical data to save storage space while still being able to appear theoretically the exact same when re-uploaded. For images that could use substantial storage space, compressed file types are practical.

In some cases, you can compress a BMP file. However, note that bitmap files are uncompressed by default. Depending on if your computer has a pre-installed program, you may be able to simply right-click on the image, click “Send To”, and choose the option that says something along the lines of “Compressed Folders”. There are also online programs that allow you to compress your BMP file.

Is Bitmap Better Than PNG?

When comparing lossless, uncompressed BMP files to other file types, one of the most common rivals is Portable Network Graphics (PNG) files. PNG files are lossless, compressed files, making them a familiar favorite among graphic designers.

Bitmap files are better than PNG files in some circumstances, while PNG files are better in others. BMP files are useful for when you have the storage space and want to edit the most minute details in your image, while PNG files provide an almost equally high-quality image while saving space.

If you are experienced in graphic design – particularly with editing intricately – you will appreciate the higher quality of a BMP file over a PNG file. On the other hand, PNG files still retain excellent quality while using compression to save space on your computer. 

One major downside to BMP files is that they typically have a limit of 4GB. While the entire 4 GB can be recovered upon uploading, PNG files can compress and almost fully retain the quality of images up to or more than 140GB. BMP files are favored among graphic designers for storing images over long periods.

Is Bitmap High-Quality?

As you have learned, Bitmap files keep your image definition as crisp as before you convert it into a Bitmap. BMP files are raster formats, meaning they are comprised of a bunch of individual pixels. Each of these pixels is held intact when converted into a Bitmap, making editing even the smallest details on a BMP file a breeze. 

Placeit For Graphic Design

Regarding the creating, saving, converting, and downloading of images and designs, there is no better software to recommend than Placeit. Placeit has thousands of logos, templates, layouts, and designs for you to choose from, customize, and create all of your graphic design projects.


Bitmap is a lossless, uncompressed, raster file type that is great for storing large images and editing small details. While it does not check every box in terms of efficiency and practicality, there are certainly pragmatic uses for BMP files.
