Long Screenshot - Seamshot

Long Screenshot made simple: stitch a pile of screenshots into one clean, long image with automatic seam removal, scroll capture and PDF export.
Seamshot joins your screen captures into a single scrolling screenshot and removes the repeated seams for you, so the result reads like one continuous page.

STITCH SCREENSHOTS
• Pick screenshots from your gallery and stitch them vertically into one long image
• Overlap detection removes the repeated status bar, toolbar and navigation bar between shots
• Drag to reorder or delete pages, and adjust the seam by hand whenever you want to
• Horizontal stitching too, for panoramas and wide tables

CAPTURE WHILE YOU SCROLL
• Start capture, then scroll any app yourself and tap the floating camera button after each scroll
• Tap the check button to finish, and Seamshot stitches the shots automatically
• No accessibility service, nothing runs in the background

SPLIT & EXPORT
• Split one long image into evenly sized pages (1:1, 4:5, 9:16 or custom) with overlap
• Export as PNG, JPG or a single A4 PDF, great for chat evidence and documents
• Hide parts with mosaic or black bars before you share
• Add a card background and a watermark to finish the look

GETTING STARTED
• To merge existing images: pick your screenshots from the gallery, let overlap detection trim the repeated bars, then reorder, delete or fine-tune any seam
• To capture a scrolling page: start capture, scroll the app yourself, tap the floating camera button after each scroll, then tap the check button to finish
• Export the result as PNG, JPG or an A4 PDF, or split it into pages first

WHO IT IS FOR
• Anyone who wants to combine multiple gallery images into a single vertical image or a horizontal panorama
• People who want to capture long scrolling pages without a background accessibility service
• Anyone who needs to turn a long capture into an A4 PDF document
• Anyone who wants to split a tall image into evenly sized pages for social media
• Users who value privacy and prefer an offline tool with no account or sign-up

TIPS
• Keep the check button for last: tap it only after your final scroll and shot
• If a seam does not look right, adjust it by hand instead of retaking the shots
• Reorder or delete pages if a shot came out twice or in the wrong order
• Use overlap when splitting so no line of text gets cut between pages
• Cover names, numbers or other sensitive details with mosaic or black bars before sharing chat evidence
• Choose horizontal stitching for wide tables and panoramas
