📤 Drag images here or click to upload
Supports PNG, JPG, GIF, WebP formats. Upload multiple images at once.
This tool is easy to use. Just follow these simple steps to stitch your images together:
Upload Images: Click the upload area to select images, or drag and drop images directly onto the page. You can upload multiple images at once, or add more in batches. After uploading, thumbnails will appear below the settings area. You can drag thumbnails to rearrange the stitch order.
Choose Stitch Mode: The tool offers three layout modes. Horizontal mode arranges images from left to right, ideal for creating panoramas or wide banners. Vertical mode stacks images from top to bottom, perfect for stitching long screenshots or chat records. Grid layout arranges images in a matrix of rows and columns, great for photo walls or album layouts.
Adjust Parameters: The gap parameter controls the spacing between images in pixels. The background color sets the fill color for any empty areas between images of different sizes. The radius parameter adds rounded corners to each image for a more polished look. When using grid layout, you can also adjust the number of columns (2 to 6).
Generate and Download: Click the "Generate Stitch" button to see the result in the preview area. You can zoom in to inspect details. When satisfied, click "Download" to save the result as PNG or JPG. All processing happens locally in your browser; nothing is uploaded to any server.
The image stitcher has a wide range of practical applications in daily life and work:
Long Screenshot Stitching: When capturing long web pages or chat conversations on a phone, you often need multiple screenshots. This tool lets you stitch them vertically into a single seamless long image for easy saving and sharing. Compared to manual editing with image software, this tool is simpler and more precise.
Photo Wall Creation: When sharing multiple photos on social media or blogs, stitching them into a single image avoids cluttering the feed and creates a more professional layout. Using the grid layout mode, you can easily create photo walls for travel albums, product showcases, and more.
Design Portfolio Layout: UI designers often need to display multiple page mockups together. Horizontal mode is great for showing pages side by side, while vertical mode suits displaying different states of the same page. Consistent spacing and rounded corners make the stitched result look more polished.
E-commerce Image Processing: E-commerce platforms often have limits on the number of product images. Using the grid layout, you can stitch different angles and detail shots into a single composite image. This saves upload slots while giving customers a complete view of the product at a glance.
Canvas Stitching Principle: This tool uses the HTML5 Canvas API to stitch images directly in your browser. Each image is loaded as an Image object and drawn onto the Canvas using the drawImage method. Canvas supports pixel-precise control, ensuring the stitched result matches the originals exactly with no quality loss. After stitching, the toDataURL method exports the Canvas content as PNG or JPEG data URLs, which are then downloaded to your device.
Image Format Comparison: PNG supports transparency, making it ideal for images with transparent backgrounds, but produces larger file sizes. JPEG offers better compression and smaller files, but does not support transparency. This tool defaults to PNG output for maximum quality, while also providing a JPEG option for smaller files. WebP offers superior compression but is not universally supported, so this tool does not output WebP directly.
Benefits of Browser-side Processing: Unlike server-dependent image tools, this tool runs entirely in your browser. Your image data never leaves your device, eliminating any privacy risk. Local processing is also faster since it is not constrained by network speed or server bandwidth. Even high-resolution images can be processed quickly. The tool's speed depends entirely on your device's performance.
No. This tool uses HTML5 Canvas to stitch images at their original pixel precision. The output maintains the exact resolution of your source images without any lossy compression. The final download is a lossless PNG format, ensuring your stitched result is as sharp as the originals.
PNG, JPG/JPEG, GIF, WebP, and BMP formats are supported. Animated GIFs will be captured as a single static frame for stitching. PNG is recommended for the best stitching results, especially when transparency is involved.
There is no hard limit, but browser memory constraints apply. We recommend stitching no more than 50 images in a single session. For very large images (such as 4K photos), consider processing in smaller batches to ensure smooth performance.
Yes. This tool runs entirely in your browser on your local device. Your images are never uploaded to any server. You have full ownership and usage rights over the stitched result, including commercial use.
After uploading, thumbnails appear below the settings area. You can drag and drop thumbnails to rearrange the order, and the preview will update accordingly. Click the delete button in the top-right corner of a thumbnail to remove an unwanted image.
The grid layout supports 2 to 6 columns. The tool automatically calculates the required number of rows based on your image count, distributing images evenly across the grid. If the total number of images is not evenly divisible by the column count, the last row will contain the remaining images.
No. The output contains absolutely no watermarks or branding. You download a clean, pure stitched image that you can use freely without any attribution requirements.
Yes. This tool uses responsive design and works perfectly on phones, tablets, and desktop computers. All features including image upload, drag-to-reorder, parameter adjustment, and download are fully functional on mobile devices.
