Your Sorted PDFs Are Now Searchable

A scanned page is a picture. Your computer can show it, but it can't search it. From today, every document PaperSweep sorts for you comes back with the words on the page built in.

TL;DR — Sorted documents now contain an invisible text layer. You can search inside them, copy text out of them, and your computer's search finds them by their content. It's switched on by default and costs nothing extra.

What changes for you

  • Search inside a document. Open a sorted PDF, press Ctrl+F (or Cmd+F on a Mac) and look for an amount, a contract number or a name.
  • Copy text out. Select an IBAN or an address and paste it somewhere else instead of typing it.
  • Find files by content. Spotlight on a Mac and Windows Search can index the text, so "insurance 2026" finds the right letter even if the file name doesn't say so.

How it works

To sort your documents, PaperSweep already reads every page. Until now, that text was only used for sorting and naming. Now it's also placed into the PDF as an invisible layer, exactly over the printed lines. The page looks the same as before; it just understands its own words.

Because the reading happens anyway, this needs no additional processing and costs nothing extra. Pages that already contain text, for example a PDF you downloaded, are left as they are.

Good to know

On very crumpled or noisy scans, the highlighted area when you search can sit slightly off the word on screen. The search still finds it, and copying still works.

If you prefer the files without a text layer, untick "Make PDFs searchable" before you start sorting.

Try it

Upload a batch on papersweep.eu, open one of the sorted files and search for a word you can see on the page.
