How to Stitch Screenshots Together
Creating a long screenshot from multiple captures is simple with our browser-based image stitcher. Follow these steps to merge your images into one:
- Upload screenshots: Drag and drop your images or use the file selector. We support PNG, JPG, and WebP.
- Arrange order: Use drag-and-drop to place your screenshots in the correct sequence. You can also use the up/down arrows for precision.
- Crop repeated areas: Use the crop tool to remove unwanted navigation bars, headers, or repeated content between captures.
- Choose vertical or horizontal: Decide whether to stack your images vertically (perfect for chats) or side-by-side.
- Adjust overlap/spacing: Use manual overlap to create a seamless join or add spacing for a grid-like look.
- Create and download: Click "Create Stitched Image" and download your full-resolution result instantly.
Merge Screenshots Vertically
Vertical stitching is the most popular way to combine screenshots. It's essential for creating long images of chats and conversations, full webpage captures, digital receipts, mobile app screens, and step-by-step tutorials. By stacking images vertically, you preserve the natural scroll of the original content.
Combine Images Horizontally
Side-by-side image stitching is perfect for before-and-after comparisons, creating panoramic views, or displaying product variants. Our horizontal mode automatically normalizes heights to ensure your images align perfectly without stretching or distortion.
Remove Repeated Headers
When taking multiple screenshots of a scrolling page, the header or navigation bar often repeats. Our built-in crop tool allows you to trim the top or bottom of specific images (or all except the first/last) to eliminate these duplicates for a clean, professional stitch.
Seamless Overlap Join
If your screenshots have overlapping content, use the manual overlap control. By sliding images over each other by a precise pixel amount, you can hide repeated segments perfectly. This is the secret to creating truly seamless long screenshots that look like a single capture.
Private Browser Stitching
Privacy is built into the core of our screenshot merger. All image processing—decoding, cropping, stitching, and encoding—happens locally in your browser's memory. Your screenshots are never uploaded to a server, ensuring your private data stays on your device.
PNG vs JPEG vs WebP: Which Format to Choose?
| Format | Best For | Advantages |
|---|---|---|
| PNG | Text, screenshots, icons | Lossless quality, preserves sharp text, supports transparency. |
| JPEG | Photos, realistic images | Smaller file sizes for complex imagery, widely compatible. |
| WebP | Web use, modern apps | Superior compression (usually 30% smaller than PNG/JPG). |
Why Are My Screenshots Different Widths?
It's common for screenshots captured on different devices or browser windows to have varying dimensions. Our image stitcher handles this through normalization. You can choose to match the width of the first image, the widest image, or the narrowest. This ensures a uniform look for your combined image without distorting the original aspect ratio of your screenshots.
Frequently Asked Questions
How do I combine multiple screenshots into one image?
Simply upload your screenshots, arrange them in the desired order, adjust stitching settings like direction and overlap, and click 'Create Stitched Image' to download the final result.
Can I merge screenshots vertically?
Yes, vertical stitching is the default mode. It stacks screenshots one below another, which is ideal for long conversations or full-page captures.
Can I combine images horizontally?
Absolutely. Switch the direction setting to 'Horizontal' to join your images side-by-side, perfect for comparisons.
Can I remove repeated headers?
Yes, use the 'Crop' button on each screenshot to trim top or bottom pixels. This is perfect for removing overlapping navigation bars.
What does screenshot overlap do?
Overlap allows you to slide the next image over the previous one. If your screenshots contain the same content at the join point, manual overlap hides the repetition for a seamless look.
Can I reorder screenshots?
Yes, you can drag and drop screenshots in the list to change their sequence, or use the 'Move Up' and 'Move Down' buttons.
Does stitching reduce image quality?
No. We use your original high-resolution source files for the final stitch. Unless you choose a compressed JPEG/WebP setting, the quality remains lossless.
Can I download the result as PNG?
Yes, PNG is our default export format as it preserves the highest quality for screenshots.
Are my screenshots uploaded to a server?
No. All processing is done 100% locally in your browser. Your images never leave your computer or mobile device.
Is there a watermark on the output?
No, our tool is free to use and does not add any watermarks to your stitched images.
Can I use the tool on mobile?
Yes, the tool is fully responsive and works on iPhone, Android, and tablets directly in the browser.
