Create compressed ZIP files with our easy-to-use and free tool. Our tool lets you upload a PGM (Portable graymap format) file and compress and convert this file to a ZIP (ZIP Archive) file that you can then download and edit or use within your applications.

The PGM file format is a bitmap image format used to store grayscale images in either a text or binary format. The text format, which is known as P2, enables easy manual editing of the image data due to it being stored in a human-readable format.
Greyscale data is stored within the file using values between 0 and 255; this gives 256 levels of gray, with 0 being black and 255 being white, and everything in between being a different shade of gray.

The ZIP file is one of the most common types of compressed file types available and is widely used to compress any file type and give great compression results, leading to smaller file sizes. ZIP files were originally released in 1989, and over time, the format has undergone many revisions.
ZIP archives can contain any number of folders and files and can use many different compression algorithms to perform the file compression, though DEFLATE is the most common one in use. The format has built-in support in many operating systems, including Mac OS and Microsoft Windows.
First click the "Upload..." button, select your PGM file to upload. Select any configuration options. When the PGM to ZIP conversion has completed, you can download your ZIP file straight away.
