Convert your PNG to FAX image files with our easy-to-use and free tool. Our tool lets you upload a PNG (Portable Network Graphics) file and, from this, create a new image saved in the FAX (Group 3 FAX) 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 PNG image files; up to 200 files at a time can be converted.
Along with converting PNG image files to FAX, 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 PNG 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.

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.

The FAX file format introduced in the 1990's is a raster image file format intended to store digital versions of documents used by Fax (facsimile) machines that were popular at the time.
Although Fax machines have been slowly replaced since then by internet based communications such as Email and Instant Messaging the FAX file format is still used for certain applications and the files can be edited within some 3rd party applications.
