Combine photos in seconds: drop them in, pick a layout, and download one image. No upload, no signup, no watermarks.
or drop images here or paste (Ctrl+V / ⌘+V)
Pick horizontal for side-by-side comparisons, vertical for stacked sequences like tutorials or long screenshots, and grid for collages and product sheets. Each layout adapts automatically as you add, remove, or reorder images, so you spend time on the composition instead of wrestling with the canvas.
Rearrange your images by dragging thumbnails in the side panel. The preview updates instantly, which makes it easy to experiment with sequencing, which matters when the order of a before/after comparison or a storyboard actually changes the meaning.
Spacing and border thickness are expressed as a percentage of the largest image, so the proportions stay consistent whether you are combining phone snapshots or 4K photos. Use zero spacing for seamless joins, or open it up to give each image room to breathe.
Choose any background or border color from the picker. Apply rounded corners up to 50%, or set the image shape to circle for avatar-style collages. A transparent background option is available when exporting to PNG or WebP, which is handy for compositing in design tools afterwards.
When your images have different sizes, choose how they line up: keep originals, magnify the smallest to match the largest, reduce the largest to match the smallest, or crop everything to a uniform size. Each mode trades off quality and consistency differently. The tips section below explains when to use which.
Download the combined image as JPEG, PNG, or WebP at the original combined resolution, up to 8000 pixels on the longest edge. JPEG is best for photos and small file sizes, PNG preserves perfect quality and supports transparency, and WebP delivers modern compression for modern browsers.
Click "Choose Images" to open the file picker, drag photos onto the page, or paste from the clipboard with Ctrl+V (⌘V on Mac). JPG, PNG, WEBP, and GIF are all supported. There is no upload step. Every image stays in your browser, which makes loading instant even for large batches.
Horizontal works for two or three images shown side by side. Vertical suits longer sequences like step-by-step screenshots. Grid is the right choice for four or more images and lets you set the number of columns. You can switch layouts at any time without losing the edits you have already made.
Drag thumbnails to change the order. The buttons on each thumbnail let you rotate in 90° steps, flip horizontally, duplicate, or remove an image. The preview reflects every change immediately, so you can iterate quickly without committing to anything.
Adjust spacing to control how tightly the images sit together, add a border with a custom color, set a background color, or apply rounded corners. For collages where consistency matters, set a fixed aspect ratio (1:1, 4:5, 16:9, 9:16) so the final image fits a specific platform without being cropped on upload.
Click Download and pick a format, or use Copy to place the result directly on your clipboard for pasting into another app. The exported file is at full resolution, with no watermark, no quality loss, and no signup required.
For renovations, makeovers, photo edits, or fitness progress, a horizontal layout with zero spacing produces a clean comparison that reads at a glance. Use "Reduce" mode so both photos line up regardless of their original dimensions, and consider a thin border to visually separate the two halves.
Instagram, Facebook, and Pinterest each favor certain dimensions. A 2×2 or 3×3 grid set to a 1:1 aspect ratio produces a square collage that fits Instagram's feed without cropping. For Stories or Reels, use a vertical layout at 9:16. A small spacing value with a white background creates a clean, modern look that works on either light or dark themes.
If you sell on Etsy, eBay, Shopify, or another marketplace, a single combined image showing multiple angles of one product often performs better than a gallery of separate photos. A 2×3 grid with a white background and consistent crop gives buyers an immediate sense of the item without forcing them to click through.
For recipes, craft guides, or software walkthroughs, a vertical layout creates a self-contained tutorial that is easy to share on blogs or in messaging apps. Duplicate the first image if you want to use it as a hero shot at the top, and add light spacing so the individual steps remain visually distinct.
Combine the highlights of a trip or event into a single image worth sharing. A larger grid (3×3 or higher) lets you tell a fuller story without flooding someone's timeline. Mix portrait and landscape shots by using "Crop" mode to keep cells uniform.
Original preserves every image at its own size, which is fine in grids but creates jagged edges in horizontal or vertical layouts. Reduce is the safest default for mixed sizes, since it scales everything down to match the smallest without distortion. Magnify upscales smaller images, so be cautious with low-resolution sources where the softening will be visible. Crop trims from the center to a uniform size, which works well for tightly-packed grids but discards content at the edges.
Use JPEG for photographs that will be shared on social media or by email, since it produces smaller files with quality that is visually indistinguishable from the original at high settings. PNG is the right choice when you need transparency, when the image contains text or sharp edges, or when you plan to edit it further. WebP offers the best of both worlds and is supported by all modern browsers, but double-check that your destination platform accepts it before relying on it.
Heavy borders draw attention to each individual image, which suits product sheets and polaroid-style collages. Thin borders or pure spacing produce a calmer, more cohesive composition. As a rough rule, spacing around 2–4% with no border looks magazine-clean, while a 1% border with no spacing creates a tighter editorial grid.
Instagram feed posts work best at 1:1 (square) or 4:5 (portrait). Stories, Reels, and TikTok use 9:16. YouTube thumbnails are 16:9. Pinterest favors taller 2:3 images. Setting the aspect ratio in the More options panel makes sure the exported file fits the platform without being cropped automatically on upload.
No. Image Combiner runs entirely in your browser using JavaScript and the HTML5 Canvas. Your photos are never sent to our servers or any third party, and they never leave your device. This is also why the tool feels almost instant. There is no network round trip waiting on a remote upload or download.
You can upload JPG, PNG, WEBP, and GIF (the first frame is used for animated GIFs). The combined image can be exported as JPEG, PNG, or WebP. Choose PNG or WebP if you need to preserve transparency; choose JPEG for the smallest file size at high visual quality.
Horizontal suits two or three images you want to read left to right, such as comparisons, panoramas, or progress shots. Vertical works for sequences that flow top to bottom, such as tutorial steps or long screenshots. Grid is the right choice for four or more images, or whenever the overall composition matters more than the reading order.
Original preserves each image at its native size. Magnify enlarges smaller images to match the largest in the set, which can soften low-resolution sources. Reduce scales the largest down to match the smallest, which is the safest default for mixed dimensions because it never enlarges anything. Crop trims from the center to a uniform size, which produces a perfectly even grid but discards content at the edges.
Upload your two images, select the horizontal layout, and set spacing to zero. Use "Reduce" or "Crop" mode so both halves end up the same height. A thin border with a contrasting color (white or black usually works well) makes the dividing line clear without dominating the composition.
Yes. The sizing modes exist exactly for this. "Reduce" is usually the most forgiving, because it never enlarges anything, so quality is preserved. If you need a perfectly uniform grid and you do not mind losing some edge content, switch to "Crop" instead.
Choose the grid layout, set the number of columns to match your photo count (2 columns for 4 images, 3 for 9, and so on), open "More options" and set the aspect ratio to 1:1. The exported image will fit Instagram's feed without being cropped on upload.
There is no fixed limit, but combining a very large number of high-resolution images can slow your browser down because all of the work happens locally on your device. For more than around 30–40 images, grid layouts handle the count better than horizontal or vertical, and lowering the maximum output dimensions in "More options" helps if you run into memory pressure.
The combined image is automatically scaled to fit within 8000 pixels on its longest edge to keep export reliable across browsers. Aspect ratio is always preserved. If you need a smaller file for sharing, set explicit width and height limits in "More options" before downloading.
Yes. The interface adapts to phone and tablet screens, and the drag-to-reorder controls, color pickers, and all other features work with touch. Pasting from the clipboard depends on the mobile browser. Safari and Chrome on recent versions both support it.
A transparent background lets the spacing between images become see-through, which is useful when you plan to place the combined image on top of another design in tools like Photoshop, Figma, or Canva. Transparency is only preserved when exporting to PNG or WebP. JPEG does not support it and will fall back to a solid color.
Yes. There is no signup, no paid tier, no watermark on exported images, and no limit on how many times you can use it. The site is supported by advertising, which is why you may see ads alongside the tool.
