Photo Collage

What is Photo Collage?

A collage is the difference between sending six photos individually and sending one image that tells the whole story. For an event recap, a trip summary, a before-and-after, a product variant grid, or a comparison shot, a collage works better in every channel that prefers a single image: Instagram, LinkedIn, email, printed greeting cards. This tool builds collages of 2 to 9 photos from a set of preset layouts (2x1, 2x2, 3x2, 3x3, asymmetric grids) and lets you tune spacing, background color and corner radius. The output is a single high-resolution PNG, exported at the largest dimensions the source images allow. No watermark, no signup, no upload, the entire compositing runs locally.

Why use this tool?

Compositing runs on a Canvas at the largest dimensions any source image supports, so the output is print-ready unless one of the inputs was a small thumbnail. Drag-to-rearrange lets you swap photo positions after the layout is chosen, without re-uploading. Background color and gap thickness are both adjustable. Setting the gap to 0 produces a continuous mural look, setting it to 20-40 pixels with a white background produces the classic photo-paper grid look. Corner radius adds a subtle softness for social-media posts that lean modern.

Common use cases

The most common case is social media. A 3x3 grid is the standard Instagram Reels cover format, a 2x1 horizontal is the standard before/after for fitness, real estate, or product photography. A 1x2 vertical mirrors LinkedIn's two-photo post layout. Other workflows: greeting cards and photo prints, where one composed image is easier to size for a 6x4 print than six separate photos; trip recaps where a 3x3 of the best shots reads better than a dump of fifty; ecommerce listings where multiple angles of a product fit into a single hero image; family newsletters where the year-in-review is one collage instead of an attached folder. Aspect ratios and spacing are tunable so the collage matches the destination format - square for Instagram, 16:9 for YouTube thumbnails, 4:3 for slide decks.

How to use Photo Collage

1. 1Upload 2 to 9 images by drag-drop or file picker
2. 2Pick a layout from the preset gallery (2x1, 2x2, 3x2, 3x3 and asymmetric grids)
3. 3Drag thumbnails to rearrange the order, or click a tile to swap an image
4. 4Tune background color, gap thickness and corner radius
5. 5Click Export, the collage downloads as a high-resolution PNG

Frequently asked questions

What is the maximum number of photos I can use?

Nine. Above nine, individual photos become too small to recognise, the result is busy rather than informative. For larger sets, run two collages and combine them, or use Merge PDF to assemble each batch into a printable photobook page.

Will photos with different aspect ratios look weird in a grid?

By default they are scaled to fit each grid cell and cropped to fill if needed. This produces a clean grid look but discards some of each image. Toggle 'Fit, don't crop' if you prefer to see each photo in full, which leaves small color bars around any image whose aspect does not match the cell.

Can I add text or stickers to the collage?

Not in this tool. Add the collage first, then run the result through Add Text to Image to overlay captions, dates or titles. This two-step approach keeps the collage editor focused and the text tool's typography controls richer.

What resolution is the exported PNG?

The output is sized to the largest dimensions across all source images. If you upload a mix of 4000-pixel-wide photos and 600-pixel phone screenshots, the output canvas is 4000 wide, and the smaller image is upscaled to fit its cell, which can introduce slight softness. For consistent quality, upload images that are roughly the same resolution.

Will the output have a watermark?

No. Many free collage apps add a logo to the corner of the output unless you upgrade. This tool produces a clean PNG with no watermark, no signup, no daily cap.

Are my photos uploaded?

No. The collage is composited entirely in your browser using a single Canvas draw call per source image. Nothing uploads, nothing is stored, and the export downloads directly to your device.

1. 1For Instagram, export at exactly 1080x1080 (square) or 1080x1350 (4:5 portrait). Setting the canvas larger does not improve display quality, and a smaller export will be upscaled and softened by the platform.
2. 2Crop each source photo before adding to the collage (our Crop Image tool, with a locked aspect ratio matching the grid cell). The result is tighter compositions and less hidden content in each cell.
3. 3For before/after fitness or real-estate collages, use a 2x1 horizontal with zero gap and a subtle vertical divider. The continuous frame draws the eye across the comparison rather than treating the two shots as separate images.

How does it compare?

Phone collage apps (Layout, Pic Stitch) are free but add watermarks unless you pay, and tend to compress the output aggressively. This tool exports a clean PNG at full source resolution, no watermark, no compression beyond standard PNG.
