Sheetsa Split

Split a drawing set into one PDF per sheet, named from each titleblock — entirely in your browser.

Split reads real, born-digital drawing sets — a scanned or photocopied page with no text layer is flagged for Sheetsa Archive instead of guessed at here.

Sets up to about 300 MB (an 800-sheet plotted set) split in this tab in under a minute; a tab holds roughly six times the file's size in memory while it works, so past about 500 MB it is likely to run out. For those, run the same engine as a local server on your own machine.

Also optimize each sheet (recompress JPEGs, dedupe fonts) — no separate re-upload needed Ask OCR for a second opinion on pages the text layer read weakly (finds numbers on plotted sets; a few seconds per such page — untick for a fast first pass)

Advanced: titleblock region & sheet-number pattern

Sheetsa tries several common titleblock layouts automatically (bottom-right corner, right-edge column, top-left) — leave this blank unless your firm's layout isn't one of those. Filling in a region searches ONLY that box; the pattern defaults to common AEC numbering (A-101, S201, C1.1, M-501A).
