Split by Text: Why the Cut Landed in the Wrong Place
Splitting on text is the closest thing to letting the document divide itself. It works when the marker is consistent, sits in a predictable place, and exists as text rather than pixels.
Why this comes up
Generated statements and reports repeat a heading on every section but do not always carry bookmarks. The heading is the structure, even when the PDF's outline is empty — provided the text layer and the page geometry cooperate.
Check before you run it
- Confirm the marker exists as text. A scanned page has no text to match until OCR adds a layer. Select the heading in a viewer: if it cannot be selected, the splitter cannot read it either.
- Tighten the page area around the heading. The area is set in points from the page's left and top edges. A box that includes the body text can match the marker on pages that should not start a new file.
- Use the starts-with filter for near matches. Pages that carry the same words in a different context can trigger a false split. Restrict the match to the leading text the real sections share.
When to reach for it
- A merged pack of letters repeats the recipient's address. The address changing from page to page is the boundary, so each letter becomes its own file.
- A clinical export repeats a patient identifier on every page. Split on the identifier so each patient's pages stay together without handling the file by hand.
One question we get
What text should I mark?
The words that start each new document — like “Invoice” or “Chapter”. The tool finds every occurrence, shows you a preview, and cuts before each match.
Where it fits
The tools people usually open next to Split by text:
- Resize — Change PDF page size and add margins/padding.
- Split by size — Get multiple smaller documents with specific file sizes.
- Split by pages — Split specific page ranges, or every page into a separate document.
Every tool works on a copy, so the original file is never touched. Uploads are stored under an unguessable id and deleted automatically two hours after you last open them; nothing is listed, shared or indexed. More on the security page.
