Automatically fix upside down scans

Batch rotate PDF pages automatically — no more manually fixing each mis-oriented scan. The Rotate PDF API detects orientation issues and corrects them at scale, keeping your OCR pipeline and document workflows clean.

Why scan orientation breaks your entire pipeline

OCR fails on rotated pages

Text extraction produces garbage on sideways or upside-down scans. Auto-rotation is step one of any reliable OCR pipeline.

Manual correction doesn't scale

Opening each file and rotating pages by hand is unsustainable for batches of 50+ documents. Automation makes it a background task.

Downstream review errors

When reviewers encounter sideways pages mid-document, they lose context and miss key data. Consistent orientation = consistent reviews.

How to add auto-rotation to your document intake

1

Receive scanned PDF — from scanner, email, or upload
2

POST to Rotate PDF API with auto-detect mode
3

Pass corrected PDF to OCR/extraction — all pages correctly oriented

FAQ

Can the API detect and fix orientation automatically (without specifying angles)?

Yes. In auto-detect mode, the API uses text orientation heuristics to identify pages needing rotation (90°, 180°, 270°) and corrects them. You can also specify per-page rotation explicitly.

Does it work with mixed-orientation documents?

Yes. Each page is analyzed independently. A 20-page document with 3 sideways pages will have only those 3 corrected, while the rest remain unchanged.
