Photo collage

Combines several photos into one grid image — pick the number of columns, the spacing and the background. Images keep their proportions; rows adapt to the tallest photo in them.

A whole folder of photos to get through?

The Images Bag of Tools desktop app does these jobs by the folder: convert HEIC and AVIF, compress to an exact size in KB, size passport and social photos by name, blur faces and strip GPS — with every file it writes checked before it says it worked. All offline, on your machine, with the same promise: nothing ever leaves it. See everything it does →
