Frequently asked questions
How do I turn several screenshots into one long image?
Choose Vertical, put screenshots in reading order, choose Match width, and set the gap to 0 px. Check the preview before downloading.
Can the tool remove duplicate rows where screenshots overlap?
No. Screenshot Merge does not identify overlap or find a smart seam. Trim duplicated areas first, then merge the screenshots in sequence.
Why can a long screenshot fail to export?
A merged canvas cannot safely exceed 32,767 px on either side or 120 million pixels in total. Split the job into smaller sections or reduce the source image dimensions.
Are my screenshots uploaded or changed?
No. The merge runs locally in your browser and creates a new downloaded or copied image. It does not send, overwrite, or alter the source screenshots.
