Photo Collage Maker
Arrange 2–6 photos into a collage and download as PNG.
Sobre esta ferramenta
Photo Collage Maker lets you upload 2 to 6 images and arrange them into a beautiful collage using preset layouts: 2×2 grid, 3×2 grid, hero + two (1+2), two + hero (2+1), or auto mosaic. Adjust the gap between photos and pick a border/background color. The collage is rendered on an HTML5 canvas and you can download it as a high-quality PNG — all processing happens client-side.
Como usar
- 1 Click 'Add Photos' and select 2 to 6 images.
- 2 Choose a layout preset (Grid, Hero+Two, Mosaic, etc.).
- 3 Adjust the gap size and background/border color.
- 4 Preview the collage in real time.
- 5 Click 'Download PNG' to save the result.
How a canvas collage is assembled
A photo collage is just several images placed into rectangular regions of a single larger image. This tool does that on an HTML5 <canvas>: it computes a grid of cells based on the layout you pick, then draws each of your photos into its cell. Because the canvas is a fixed 1200×1200 pixel square, the result is a high-resolution PNG you can download and print or post. All of this happens in your browser — your photos are read locally with the FileReader API and never uploaded to any server, which matters when the photos are personal.
The five layouts and how many photos each wants
| Layout | Arrangement | Best photo count |
|---|---|---|
| Grid 2×2 | Four equal cells | 4 |
| Grid 3×2 | Six equal cells | 6 |
| Hero + Two (1+2) | One tall photo left, two stacked right | 3 |
| Two + Hero (2+1) | Two stacked left, one tall photo right | 3 |
| Mosaic (auto) | Chosen automatically by photo count | 2–6 |
The Mosaic layout adapts: two photos become a side-by-side pair, three use the hero arrangement, four fall into a 2×2 grid, five produce a mixed top-and-bottom composition, and six fill a 3×2 grid. If you are not sure which layout suits your set, start with Mosaic and let it choose.
How photos are fit into cells: "cover," not "stretch"
This is the detail that makes the output look professional. Each photo is scaled to cover its cell rather than stretched to fill it. The tool picks the larger of the two scale factors needed to fill the cell's width and height, then crops the overflow evenly from the center. In practice that means a portrait photo dropped into a landscape cell is enlarged until it covers the cell, with the top and bottom trimmed equally — the image is never squashed or distorted. The trade-off is that the edges of a photo may be cropped, so keep your subject near the center of each picture.
A worked example
Add three photos and choose Hero + Two. The canvas is divided into a 2×2 grid of conceptual columns and rows, then the first photo is given a cell spanning both rows on the left (a tall "hero"), while photos two and three take the top-right and bottom-right cells. With the gap set to 8px, an 8-pixel band of your chosen background color separates every photo and frames the whole collage. Increase the gap and the photos shrink slightly to make room for wider borders; the layout always keeps the cells aligned to the grid so nothing overlaps.
Practical tips
- Match photo count to the layout. A 2×2 grid wants four photos and a 3×2 grid wants six. Supplying fewer than a layout expects leaves cells empty, so pick a layout that fits how many images you have — or use Mosaic, which adapts automatically.
- Center your subjects. Because cover-fit crops from the center outward, a face or focal point near the middle survives the crop; one near an edge may get clipped.
- Use the gap as a design choice. A 0px gap creates a seamless, edge-to-edge montage; a larger gap with a white or colored background gives a clean, framed, scrapbook look. Drag the slider and watch the preview update live.
- Pick a background color that complements the photos. The background color is also the border color between cells. White is neutral; a dark color makes bright photos pop; pulling a color from the photos themselves ties the collage together.
- Reorder by removing and re-adding. Photos fill cells in upload order. To change which image is the hero, remove photos with the × on their thumbnail and add them back in the order you want.
Common mistakes
- Adding too few or too many photos. The tool accepts 2 to 6 images and needs at least 2 to render anything. Extra files beyond six are ignored; a single photo produces no collage.
- Expecting no cropping. Cover-fit always crops to avoid distortion. If preserving the full frame matters more than a tidy grid, that trade-off is unavoidable in a fixed-cell collage — choose photos whose composition tolerates a center crop.
- Overlooking aspect-ratio mismatch. Very wide panoramas placed in a near-square cell lose a lot of their sides. Crop such images to a closer aspect ratio beforehand for a better result.
- Forgetting the output is square. The PNG is 1200×1200. If you need a different shape for a specific platform, crop the downloaded file afterward.
Why client-side matters here
Everything — reading your files, fitting them, drawing the canvas, and exporting the PNG — runs in your browser using the Canvas API. Your images are never transmitted, which makes this a private way to combine family photos, product shots, or moodboards. The download is a genuine high-resolution PNG at the full canvas size, suitable for printing, social posts, or dropping into a document.
