How it works
The frame and the matte
Pick a shape (portrait presets, or landscape with the swap box) and an output width of 1080, 1200, 1440 or 2048 px. The photo is scaled to fit inside the frame, centred, with optional space around it.
The empty space is filled with a blurred, enlarged copy of the photo, a solid colour, or a two-colour gradient at an angle you set. Auto uses the photo's average colour and a darker shade of it.
Limits
The long side of the output stays within 8192 px, so wide presets cap the width. Download gives a PNG named after the photo with the output size.
