MatteScale
Keep the picture you fell in love with.
I made MatteScale because a new frame should not have to cost you the edges of a favorite photo. Add a border, try a different shape, and keep the whole picture in Fit mode. If a crop suits it better, switch to Fill.

A walkthrough of framing and batch export
Find a frame you like
Try a square or a tall frame, then choose a border color. This Fit preview keeps the whole photo visible as you experiment.
Frame shape
Matte color
Different photos, one frame shape. All frames adapt in real time to your matte presets. Click any photo to inspect it on the main stage.
Fill the square or keep the whole photo
Both panels use the same 3:2 photo and the same 1:1 canvas. The crop fills it; the matte keeps the complete composition.
Fills the square and trims the wide photo at its left and right edges.
Keeps the whole 3:2 photo and adds white space inside the same square output.
