Colla is a photo collage generator. It allows you to generate collages from your photos, and comes with a variety of templates and options.


Colla allows you to load photos and generate collages based on presets. It can then save the image back to an image file.

Right now colla, supports PNG, JPEG, TIFF and GIF for loading, and can save in PNG and JPEG formats.

Among the options to customize the collages are margin and gap sized, rounded borders and background color.

Colla is hardware-accellerated for lightning-fast editing.

Download & Install

Right now, I only provide package for debian- and fedora-based linux systems. I did not test all builds extensively.

If you find Colla useful, I encourage you to support my work!
