Supported file formats and limits
What you can upload on each plan, how long a single scan can be, and how to get the cleanest result from a file.

You can paste text on every plan. Uploads are handy for longer documents because we keep paragraphs and headings intact, which makes the highlights easier to follow.
| Format | Plans | Notes |
|---|---|---|
| .docx (Word) | All plans | Tracked changes are ignored; we check the final text. |
| Essential and above | Text-based PDFs. Scanned pages need the image option. | |
| .txt | Essential and above | UTF-8 encoding works best. |
| Images (.png, .jpg, .heic) | Advanced and Team | Photos of printed or handwritten pages, read with OCR. |
Length limits
Each plan has a maximum length per scan: 1,500 words on Free, 25,000 on Essential, and 50,000 on Advanced and Team. Files can be up to 20 MB. If a document is over your limit, we'll ask you to trim it or upgrade before any credits are used.
Getting the best result from a file
- Remove cover pages, tables of contents and reference lists if you can. They aren't prose, and they dilute the result.
- For PDFs exported from slides or forms, paste the text instead. Layout-heavy PDFs can break sentences in odd places.
- For handwriting, photograph one page at a time, flat and straight on, in good light.
