Combine multiple images
into one, instantly.
An image stitcher is a tool that lets you join two or more pictures into a single file. Whether you need to stitch images together side by side, stack them top to bottom, or merge photos into one cohesive visual, our free online image stitcher handles it all directly in your browser.
No software to install, no account to create, and your images never leave your device.

One picture tells a story.
Multiple pictures tell it better.
People combine photos into one image for dozens of reasons. A before-and-after comparison makes design changes obvious at a glance. Product photos placed side by side help shoppers compare colors, sizes, or angles without switching tabs. Social media creators merge images online to build eye-catching posts that fill more screen space in a feed.
Screenshot stitching is another popular use case. Developers and testers stitch screenshots together to document bugs, capture full-page views of long web pages, or create step-by-step tutorials. Whether you are building a photo collage, combining scanned document pages, or lining up reference images for a mood board, an image joiner saves time compared to opening a full-blown editor.

When to stitch images horizontally
A horizontal image stitcher places pictures side by side from left to right. This layout works best for before-and-after comparisons, panoramic views, product photos shown in sequence, or any scenario where viewers scan from left to right.
When images have different heights, our tool automatically normalizes their heights proportionally while preserving their aspect ratio, producing a clean, seamless panorama without uneven gaps.
When to stitch images vertically
A vertical image stitcher stacks pictures from top to bottom. It is ideal for merging long screenshots, creating photo strips, combining chat conversation captures, and joining scanned document pages in reading order.
When images have different widths, our tool automatically normalizes their widths proportionally while preserving their aspect ratio, ensuring your vertical strip stacks seamlessly without jagged edges.
Tips for keeping image quality high
A few simple decisions make the difference between a crisp stitched result and a blurry one.
Use images of similar dimensions
When your images share the same width (for vertical stitching) or the same height (for horizontal stitching), the result lines up perfectly with no extra padding. If sizes differ, the stitcher fills the gap with your chosen background color, which still looks clean, but matching dimensions produces the most polished output.
Pick the right output format
PNG preserves every pixel and supports transparency, making it ideal for screenshots, graphics, and anything with crisp edges or text. JPEG compresses better and creates smaller files, making it the smart pick for photographs and social media. WebP offers the best of both worlds with strong compression and quality.
Avoid unnecessary stretching
Our image stitcher never resizes or stretches your original images. Every photo is placed at its native resolution, so text stays sharp and details stay intact. If a final result looks too large, resize the output in a separate step rather than scaling individual inputs before stitching.
Your images stay private
Every step, from uploading to stitching to downloading, happens entirely in your browser. No files are uploaded to any server. This makes our photo stitcher safe for sensitive images like financial documents, private screenshots, or unreleased product designs.
What people use an image stitcher for
Long screenshot stitching
Merge multiple partial screenshots into one scrolling capture. Perfect for preserving entire chat threads, long web pages, or multi-screen app flows.
Comparing designs
Place two design iterations side by side so stakeholders see changes instantly. Works great for UI mockups, logo variations, and color scheme comparisons.
Making a photo strip
Stitch photos together vertically or horizontally to create a classic photo-booth strip. Great for events, gifts, or Instagram stories.
Combining scanned pages
Join images of multi-page documents, receipts, or handwritten notes into a single file for easy sharing or archiving.
E-commerce product views
Combine product photos from different angles into one listing image. Buyers get the full picture without clicking through a gallery.
Panoramic images
Stitch overlapping landscape shots into a wider panoramic view. While not auto-blending, placing them side by side with zero gap creates a quick panorama effect.
A free image joiner built for speed and simplicity
Most online image stitchers either force you to create an account, slap a watermark on your result, or upload your files to a remote server. Our tool does none of that. Everything runs locally in your browser using the HTML5 Canvas API, which means your images are processed instantly and never leave your device. There are no file-size limits, no daily usage caps, and no hidden paywalls.
You get full control over the output. Choose between horizontal and vertical stitching, fine-tune the pixel gap between images, set a background fill color or keep it transparent, and export as PNG, JPEG, or WebP with adjustable quality. Drag-and-drop reordering makes it easy to rearrange the sequence before you stitch.
Whether you need to stitch photos together for a quick collage, merge pictures into one for a presentation, or combine images online for social media, this free image stitcher has you covered. Upload, configure, download. That's it.
