Convert your PBM to PNG image files with our easy-to-use and free tool. Our tool lets you upload a PBM (Portable bitmap) file and, from this, create a new image saved in the PNG (Portable Network Graphics) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple PBM image files; up to 200 files at a time can be converted.
Along with converting PBM image files to PNG, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available by selecting the Options button. Along with grayscale, you can also mirror or flip the image if needed. For single PBM file uploads, you will also see options to resize and rotate your image.
This option can be used to rotate the image in 90° increments.
When selected, this option will flip the image vertically.
When selected, this option will mirror the image horizontally.
When checked, this will apply a black and white filter to the image, turning any color image into a black and white image.
When checked, this will apply a negative filter to the image, inverting all the colors within the image.
Add a sepia effect to your image using this option. The intensity can be adjusted using the slider control.

A PBM file is a graphics file used to store black-and-white images in a format suitable for use by applications that do not need full color image capability.
The PBM format can store black and white images in a compact and uncompressed binary format, making it perfect for applications of all types.

The PNG graphics file format is a commonly used format for storing 2D images, which can be highly compressed by the use of a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.
PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990s as a superior format to GIF. PNG files are generally used for company logos, icons, and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image, hence the PNG format being unsuitable for most digital photo content.
Yes! Our PBM tool supports full batch conversions. You can upload up to 200 PBM files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the PNG files individually or download them all in a single ZIP file.
First click the "Upload..." button, and select your PBM file to upload. You can also drag and drop your file onto the tool. Once your file is selected, you can set any configuration options. When the PBM to PNG conversion has completed, you can download your PNG file straight away.
We aim to process all PBM to PNG conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the PBM file you submit to us. The resulting PNG file, once created, is stored for 4 hours after upload; after this time it is deleted, and the short-term download link will stop working. You can create a long-term download Url with most tools that will ensure the file is retained for 24 hours, allowing you to download the file when convenient. Our tools also come with a Delete button, allowing you to delete the file immediately.
No. All our conversion tools process your PBM file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted PNG file quickly.
Yes! Our PBM to PNG tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
