Create polished photo collages and long image layouts in minutes

Collage Pro supports JPG, JPEG, PNG, WEBP, and other common image formats. For best results, upload the original or highest-resolution files available, then choose PNG, JPG, or WEBP based on where you plan to publish.

No. Collage creation, cropping, zooming, rotation, and export all run locally in your browser. Your image data is not uploaded to Collage Pro servers. Export or save a local project before refreshing or switching browsers.

Export quality depends on canvas size, source image resolution, export format, and quality settings. PNG is best for crisp text and hard edges, while JPG and WEBP are practical for photo-heavy layouts. For social publishing, use quality settings of 0.9 or higher.

Yes. Use the local Project Library to save editable collages in your current browser with IndexedDB, then continue adjusting images, layouts, and styles later. Collage Pro does not upload your images to cloud storage, so export finished work before clearing browser data.

Yes. Collage Pro is responsive and works on phones, tablets, and desktop browsers. Mobile is great for quick layouts and exports; larger multi-image projects are usually easier on a tablet or desktop.

Photo collage mode supports up to 16 images in a single layout. Long image stitching has no fixed item limit, but large projects depend on device memory; for stable exports, we recommend keeping each stitch under 50 images.

Yes. Core collage, long-image stitching, basic editing, and export features are free with no sign-up required. Pro unlocks extra templates, brand kit tools, and productivity features for users who create frequently or need consistent branding.

Yes. The homepage, editor, articles, tool pages, and docs are available in both English and Chinese, which is helpful for multilingual teams and creators publishing to global platforms.

You can create social media grids, product multi-angle showcases, travel collections, event recaps, portfolio boards, tutorial screenshots, long chat screenshots, and before-and-after comparisons. Start from templates or adjust ratio, spacing, radius, background, and image positioning manually.

Start with sharp source images and avoid stretching low-resolution photos into large frames. Set the canvas size to the pixel width required by your target platform before exporting. Use PNG for layouts with text, logos, or screenshots, and high-quality JPG or WEBP for photo-heavy collages.

Yes. Collage Pro can be used for product images, branded content, client presentations, and marketing assets. Make sure you have the rights to use uploaded photos, logos, fonts, and materials; Collage Pro handles editing and export, not copyright or licensing review.

No. Open the web app and start creating without installing desktop software or signing in for core features. If you need cross-device sync or cloud backup, export your images and keep any source assets separately.
