Free combine images online tool.

Drop two or more photos onto the combiner (up to nine). Pick a layout: side by side, stacked vertically, or a grid. Adjust the gap and background color if you want, reorder photos with the arrows, then click download. The merged image is built in your browser at full resolution; nothing uploads.

Yes. Side by side is the default layout: drop your photos and they line up horizontally, scaled to a common height so nothing looks stretched. No account, no watermark, no size limits. Use the gap control to add space between them or set it to zero for a seamless join.

Up to nine in a single pass. Two or three work well side by side or stacked; four or more usually look best in a grid (2 × 2 for four, 3 × 3 for nine). For more than nine, combine in passes: merge a batch, download it, then feed that result back in with the rest.

No. Photos are drawn onto the output canvas at their source resolution; nothing is compressed until the final export, where you control the format and quality. Export PNG for lossless output, or JPEG at 95%+ for visually lossless results.

Yes. Each slot scales its photo to fit the layout while keeping its aspect ratio. Mismatched sizes are normalized so the final image looks even, with the background color filling any leftover space.

Yes. No accounts, no daily caps, no watermark, no upload. Everything runs in your browser using canvas; we never see your photos.

That is one of the most common uses: drop the before photo first and the after photo second, keep a thin gap between them, download. Use the arrows to swap the order if they land the wrong way round. For social posts, the vertical stack suits tall before/after layouts.

Input: JPG, PNG, WebP, and iPhone HEIC (decoded in the browser automatically). Output: JPEG, PNG, or WebP with adjustable quality. Transparent PNG inputs keep transparency when you export PNG.

Drop four or more photos, pick the Grid layout, and choose how many columns (Auto picks a square-ish arrangement, or set 2, 3, or 4 yourself). Cell fit decides whether photos are cropped to fill each cell (Fill, tidiest for mixed shapes) or letterboxed whole (Fit, keeps every pixel). Add a gap and pick a background color for classic collage spacing.

They are opposites. Combining merges several photos into one picture. Splitting cuts one picture into equal tiles (for example a 3×3 Instagram mosaic). We have a dedicated tool for each; this page combines.
