What this workspace does
A reviewable, ordered screenshot stitch with clear overlap removal.
Image layout · browser local
Join screenshots into one long image
Choose screenshots in the desired order and make one vertical local image. The stitcher detects only clear adjacent overlap to avoid duplicating scroll regions.
Use it accurately
Review the final stitch before sharing: repeating headers or visually similar sections can still need manual attention.
Private browser processing
Selected files are processed in the current browser session. Aftermath has no account, cloud file storage, or server-side file-processing job.
How to use this tool
Join ordered local screenshots into one long image when the source captures belong in a continuous vertical sequence. The browser stitches the selected readable images and offers a separate output for review. Overlaps, inconsistent widths, device chrome, and missing content can affect the result, so inspect the final image before sharing it.
What to choose and what you get
What to choose
- two or more ordered screenshots in a browser-decodable image format
Result
- one separately downloaded long stitched image
Supported formats
- Accepted formats: JPG, PNG, WebP.
- Output formats: JPG, PNG, WebP.
Browser support and permissions
- Modern browser with JavaScript, a supported image decoder, and enough memory for the selected image.
- No camera, microphone, or screen permission is needed.
Worked example
Four overlapping mobile screenshots need one long reference image with duplicate overlap removed manually by placement.
Starting facts
- The screenshots were captured in top-to-bottom order.
- Changing page content between captures can prevent a clean seam.
Observed operation: Arrange the screenshots, inspect overlap and create one vertically stitched image in the current browser.
Review the result: Zoom across each seam for repeated or missing rows and confirm the final order before downloading.
Boundary: The stitcher cannot reconstruct changing content, hidden regions, perfect parallax correction or evidentiary authenticity.
Check your result
- Review the final stitch before sharing: repeating headers or visually similar sections can still need manual attention.
Things to know
- Review the result on the intended device before relying on it.
Privacy boundary
The selected image stays in the current browser session and is not sent to an Aftermath processing service. How local processing is verified.
What this tool verifies
Checks the displayed limits and reports or creates one separately downloaded long stitched image from two or more ordered screenshots in a browser-decodable image format.
Check before sharing
A local measurement or export does not guarantee acceptance by an external destination.
