It can also capture opened Feishu / Lark PPT and presentation previews slide by slide. Capture the whole, preserve with restraint. Why install ScrollCatch - Capture a complete page, continue downward from the current position, or select a custom range. - Continue extremely long pages in linked sections while preserving the exact end position. - Review captures quickly, then open one unified workbench only when you need precision editing. - Crop freely, enter precise values, add custom page breaks, reorder sections, and combine exports. - Export real A3, A4, A5, B5, Letter, Legal, and Tabloid PDF sizes in portrait or landscape. - Export full PNG or JPEG images, paginated image ZIP files, individual PDFs, or one combined PDF. - Capture opened Feishu / Lark presentation previews slide by slide and export by page. - Press Esc to stop an active capture and keep completed content, or cancel range selection. - Switch between English and Chinese; English is the default and an explicit Chinese choice is remembered locally. A workflow designed for long content ScrollCatch does not force an extremely long page into one unsafe canvas. When a section reaches the practical limit, it saves the result and the end position. Review the seam, return to the source, continue with the next section, then reorder, crop, paginate, and combine everything in the same workbench. The workbench uses lightweight previews to stay responsive. Temporary softness in the preview does not affect exports; PNG, JPEG, and PDF output is rendered again from the original locally stored capture slices. Privacy ScrollCatch is local-first. Screenshots, editing drafts, and temporary cache remain in browser extension storage and are not uploaded to external servers. The extension contains no account system, advertising, analytics, or remote code. Project homepage: github.com/Yifo98/ScrollCatch
