Merge images online —
combine photos into one
Combine two images into one, or stitch a dozen together side by side or stacked. Drag to reorder, set the spacing, and download — all in your browser.
Drop two or more photos to combine
Add as many images as you like — they'll join side by side or stacked. Everything runs in your browser, so nothing is uploaded and nothing is stored.
Combine photos in under 20 seconds
No account, no upload, no waiting. Here's the whole flow start to finish.
Three steps, explained
Everything you need to combine images online — nothing you don't.
Drop two photos — or a dozen
Drag your images anywhere onto the drop zone, or click to browse. They open instantly because nothing is uploaded: each file is read straight into a canvas on your own machine.
- No cap on how many images you merge
- JPG, PNG, WebP, AVIF, HEIC, GIF, BMP, TIFF, SVG
- Different sizes are matched automatically
Side by side, stacked, or a grid
Pick horizontal to place photos side by side — best for before-and-after comparisons. Pick vertical to stack them top to bottom, which is what you want for stitching long screenshots. Drag the thumbnails to change the order.
- Three layouts, switched with one tap
- Drag thumbnails to reorder instantly
- Preview updates live as you change anything
Add spacing, then download
Slide in a gap between photos, round the corners, and set a background colour — or keep it transparent. Then download as PNG, JPG or WebP. No watermark, no signup, no limits.
- Spacing and corner radius sliders
- Transparent or any custom background colour
- Full resolution — merging never softens your photos
How to merge images into one
Add your photos
Drop in two or more images. They load instantly and stay on your device — no upload, no queue, no account.
Choose a layout
Side by side, stacked, or grid. Drag thumbnails to reorder, and the preview updates the moment you change anything.
Download
Set spacing and background if you want them, then save your combined image as PNG, JPG or WebP.
Built for the joins you actually need
Combine two images into one
The classic before-and-after. Drop both, pick side by side, and you've got a single shareable file in seconds — no design app needed.
Combine multiple images into one
Two, ten, or twenty — merge multiple images online in one pass, and drag the thumbnails to get the order exactly right.
Stitch images into a long screenshot
Vertical mode joins screenshots top to bottom into one tall image — the tidy way to share a whole chat thread or a step-by-step guide.
Nothing gets uploaded
The merger runs on a canvas inside your browser. Your photos never touch a server — which is also why it's instant.
Spacing, corners & background
Most mergers glue photos edge to edge and call it done. Add a gap, round the corners, or drop in a background colour — or keep it transparent.
Full quality, matched sizes
Different dimensions are scaled to line up cleanly, and everything is drawn at full resolution. Export PNG and it's completely lossless.
Horizontal or vertical — which should you pick?
It's the only real decision this tool asks you to make, and it comes down to what the reader needs to do with the result.
Side by side
Puts photos next to each other so the eye can compare them directly. Use it for before-and-after shots, two product options, or a pair of design variants. Heights are matched automatically so the join looks deliberate.
Stacked
Joins photos top to bottom into one tall image. This is the one for stitching screenshots — a long chat, a full webpage, a sequence of steps. Widths are matched so the seam disappears.
What people combine images for
- Before and after. A renovation, an edit, a haircut. Two photos in one frame tell the story that two separate files never quite do.
- Long screenshots. Stitching a conversation or a whole page into one tall image beats making someone scroll through six attachments.
- Product shots. Several angles in a single image, so a listing or a message shows everything at a glance.
- Upload limits. When a form only accepts one file, merging photos online is the quickest way around it.
A note on quality
Merging doesn't degrade anything — your photos are drawn into the new canvas at their original resolution, pixel for pixel. The only thing to watch is the export format: PNG keeps it lossless and supports transparency, JPG re-encodes on save but produces the smallest file for photographs, and WebP lands neatly between the two.
