Photo Collage Pro is a collage maker that runs in the browser. You pick a template, drop in your photos, and download the result. There are around 60 templates covering the usual layouts: grids, stacks, polaroid-style, magazine cover.

What it does

Drag-and-drop editing with live preview, so you can reposition and resize photos before exporting.
High-resolution export, enough for print or for social media.
A free tier that covers the core use case, with optional paid upgrades for extra templates and features.

Where it fits

Casual users who want a collage for a social post, a printed gift, or a school project. Photographers who need to lay out a contact sheet or a quick preview for a client. The tool is not a replacement for a full image editor; it does one job and does it quickly.
