Free online collage maker for your photos.

A grid merge places every image into identical cells - same width, same height, uniform spacing. The JPG Joiner on this site does exactly that. A collage uses varied cell sizes: one large hero image next to two smaller ones, or a dominant top image with three thumbnails below. This asymmetry creates visual hierarchy, which is why collages work better for social media posts and mood boards where you want one image to draw attention first. Grid merges work better for comparison sheets, contact prints, and product catalogs where equal weight matters.

JPG, PNG, and WebP. The tool reads all three formats through the browser Canvas API and outputs a JPG file. If you need lossless PNG output instead, use the PNG Merger tool on this site - it produces pixel-identical output with no compression artifacts. For most collage use cases (social media, messaging, printing), JPG at 85-92% quality is the right choice because the file is 5-8x smaller than PNG with no visible difference at normal viewing size.

Yes. You get three fit modes for each image. Fill crops the photo to completely cover the cell (landscape in a square cell loses the sides). Fit scales the whole image to show inside the cell with no cropping - letterbox bars fill any leftover space using your background color. Stretch distorts the image to fill the cell exactly, which works for abstract textures but warps faces. After choosing a fit mode, click any image in the preview to select it, then zoom from 100% to 400% and reposition with the directional buttons to frame the exact area you want. The 1 Big + 2 Small template works well when you have one landscape shot and two portrait shots.

The templates support 2, 3, 4, or 6 photos. Drop more images than a template needs and the extras are ignored (but kept in the queue so you can switch templates). The 2x2 grid handles 4 photos, the 2x3 grid handles 6, and the 1 Big + 2 Small template handles 3. On a phone with 3-4 GB RAM, 6 high-resolution photos (4000x3000 each) render without lag. On desktop, memory is rarely a concern.

You choose the output size with built-in presets: 1:1 (2000x2000 px) for Instagram feed posts, 4:5 (1600x2000 px) for Instagram portrait, 16:9 (2000x1125 px) for YouTube thumbnails, 9:16 (1125x2000 px) for Stories and Reels, 3:2 (2000x1333 px) for standard photo prints, and 2:3 (1333x2000 px) for Pinterest pins. You can also enter custom width and height values for any non-standard size. All presets produce output large enough for social media and print uses up to roughly 6.5 inches at 300 DPI.

Yes - two separate controls. The gap slider (0-20 px) sets the space between cells, filled by your background color. At 4-6 px you get clean separation; at 15-20 px the background shows through for a framed gallery look. The border control (0-20 px) adds a colored outline around each individual cell with its own color picker, independent of the background. Combine both for layered effects: try a white background with 8 px gap and a 2 px black border on each cell for a classic matted photo look.

Open the Customize Collage panel and click the color picker next to Background Color. White (#ffffff) is the default. Black (#000000) gives a gallery-style frame. The background only shows through the gaps between photos and in any corner rounding. If your gap is set to 0 and border radius is 0, the background is completely hidden behind the images. You can also type a hex code directly if you need an exact brand color.

No. The collage maker runs entirely in your browser using the HTML5 Canvas API. Your images load into local memory, get drawn onto a canvas element, and export as a new JPG file. Zero image data crosses the network. You can verify this: open your browser developer tools (F12), switch to the Network tab, and watch while building your collage. No outgoing image requests appear. Close the tab and everything is gone.

For social media posting, 85-92% is the sweet spot. Instagram recompresses uploads to roughly 70% anyway, so uploading at 100% wastes bandwidth without improving the final result. For printing, use 95-100% to preserve detail. For messaging apps (WhatsApp, Telegram, iMessage), 80-85% keeps file size under 1 MB for fast sending. The default 92% produces a file between 300 KB and 1.2 MB depending on content complexity, which works well for most uses.

It depends on what you need. Canva has the largest template library but requires an account and uploads your images to their servers. BeFunky is powerful but locks many layouts behind a paid plan. This collage maker is the best option when privacy matters and you want zero friction - no account, no upload, no watermark, no storage limits. Your images stay on your device the entire time. For complex multi-page designs with text overlays, Canva is stronger. For quick photo-only collages with full privacy, this tool wins.

This one. There are no daily caps, no watermarks, no file size limits, and no account required. Most free collage makers restrict you to 5-10 collages per day, add watermarks to free-tier output, or limit resolution. This tool has none of those restrictions because it runs entirely in your browser - there is no server to rate-limit. You can build 100 collages in a row if you want. The only practical limit is your device memory, which handles 6 high-resolution photos (4000x3000 each) without issues on any modern phone or laptop.

A photo collage maker is a tool that combines multiple photos into a single image using a layout template. Unlike a simple grid merge that gives every image the same size, a collage maker arranges photos in varied cell sizes - a large featured image alongside smaller supporting ones. The result is a single downloadable image file (usually JPG) that you can post to social media, send via messaging apps, or print. This particular image collage maker runs in your browser using the Canvas API, so it works on any device without installing an app.

Canva is a full design suite with thousands of templates, text overlays, stickers, and brand kits. This tool does one thing: combine photos into collage layouts quickly and privately. Canva requires a free account, uploads your images to their cloud, and adds a watermark to premium templates. This collage maker needs no account, keeps all images on your device, and never watermarks output. For a quick Instagram collage or Pinterest pin from camera photos, this tool is faster - drop images, pick a layout, download. For complex branded designs with typography and illustrations, Canva is the better choice.
