Collage Pro vs SnapLayout

Collage Pro is a web-based editor for combining images into photo collages, social image grids, product visuals, and long stitched images. Its collage editor accepts 1–16 photos, with more than 100 preset grids, a custom layout builder, free placement, and text overlays. Editing controls include cropping, zooming, rotation, repositioning, spacing, corners, borders, and backgrounds. Long Image mode stitches images horizontally or vertically, supports batch upload and reordering, and has no fixed item limit, although stable exports are recommended under 50 images. PNG, JPG, and WEBP exports offer quality settings from 0.1 to 1.0. Editing and export run locally in the browser, while projects can be saved in the current browser through IndexedDB rather than cloud storage. The responsive app works on phones, tablets, and desktop browsers.

SnapLayout is a photo collage maker for creating social media posts: choose a layout, add photos, and export at a size suited to a platform. Layouts include split, grid, asymmetric, and single-image options, and a carousel can contain up to 20 slides with all slides exported together. Square, portrait, landscape, and custom canvas sizes are supported; changing formats reflows a design without starting again. Export presets are listed for Instagram, TikTok, Pinterest, Twitter/X, Facebook, and YouTube, with LinkedIn also named on the features page. PNG and JPEG are supported. Free exports are capped at 1080px on the longest edge, while premium exports can reach 4K and add text overlays. The app is available on iOS and macOS. Editing works offline and projects are stored locally; iCloud sync is not available. The maker says photos are not uploaded and an account is not required. Its privacy policy separately says app use may collect device IP address, visited pages and timing, time spent in the app, and mobile operating system.
