Can I rotate every page at once?

Today, page rotation is per-page via the page thumbnail action button. Bulk "rotate every page" is on the v1.1 backlog. For documents where every page needs the same rotation, the fastest workflow is to use the keyboard shortcut on each thumbnail in sequence — about a second per page.

Does rotating a page move the annotations?

Annotations are anchored to PDF coordinates, so they rotate WITH the page when you flip its rotation. Visually, an annotation in the top-right of an unrotated page will land in the bottom-right after a 90° clockwise rotation — correct PDF behaviour. If you wanted the annotation to stay in the top-right of the new orientation, delete and re-add it after rotating.

Why does my scanner save documents sideways?

Most phone scanner apps detect orientation from text edge analysis. When the document has minimal or rotated text — a stamp, a graphic-heavy form, a Vietnamese ID card with both VN and EN labels — the detection gets confused and saves the page in the original capture orientation rather than the reading orientation. Fixing per-page rotation here is faster than re-scanning.

Can I undo a rotation?

Yes — rotate again to bring the page back. 90° clockwise four times returns to the original. Within the editor session, Cmd/Ctrl+Z undoes the most recent rotation step. The source PDF you originally dropped is held unchanged in browser memory, so you can always reset by closing and re-opening the file.

Do my files leave my browser?

No — at all, today. All editing runs client-side via pdf.js and pdf-lib. The v1.1 paid tier will add opt-in cloud OCR / unlock; even then files are deleted within 60 seconds.

Yes. Everything in the editor today (annotations, AcroForm fill, watermark, page numbers, split, merge, export) is free forever. Paid tier ($1.99/document) covers cloud OCR + AI autofill on scanned PDFs in v1.1.

How do I keep my work between sessions?

Edits autosave to your browser's IndexedDB every 500 ms. The editor URL becomes /app?s=… — copy or bookmark to return. Sessions live entirely on your device.

Can I use this for sensitive documents — tax, medical, legal?

Yes — that's the point of client-side execution. Your tax return, medical record, or legal contract literally never touches our infrastructure. Verify in DevTools' Network tab.

Does Vietnamese text export correctly?

Yes. The export pipeline auto-fetches Roboto-Vietnamese (with full diacritic coverage) when any annotation contains non-ASCII text.

Rotate PDF Pages

The full guide

Everything you need to know about rotating PDF pages.

Why pages end up sideways

The single biggest cause of sideways PDF pages is scanning — a phone's scanner app guesses the orientation from text edge detection, and gets it wrong roughly 5% of the time on documents with mixed orientation cues (a Vietnamese ID card scanned with both languages, for example). Other common causes: a multi-page PDF where one section was scanned in landscape (a wide table or signature block) while the rest is portrait, or a Word export where the orientation flag wasn't set correctly.

Per-page rotation that survives editing

PDFCatalyst sets the page rotation as page metadata in the output PDF — exactly the way Acrobat does it. PDF readers respect that metadata and display the page rotated; printers respect it and print the page rotated; PDF editors honour it and rotate the editing canvas to match. The page's underlying content is unchanged — only the display orientation flips. This means future edits (signatures, annotations) land in the correct visual position regardless of rotation.

Rotating annotations vs. rotating pages

These are two different operations. Rotating a page rotates the entire page (including everything on it). Rotating an annotation rotates just that one annotation around its own center. Use page rotation when the source PDF was scanned wrong; use annotation rotation when you want to angle a `DRAFT` text or a signature for visual emphasis. The page-thumb kebab menu and the per-annotation rotation handle are separate UI for that reason.

Privacy: rotation runs in your browser

Setting page rotation is one of the simplest PDF operations — it's just flipping a metadata flag on the page object. Server-side rotation tools still upload the WHOLE PDF to do it, then upload the modified PDF back. PDFCatalyst rotates in your browser via pdf-lib in well under a second, with zero network round-trip. The bytes never reach our servers.

Rotating then signing or annotating

Rotate first, then annotate. The annotation tools snap to the rotated page coordinate space — what you see on screen is what gets exported. If you annotate first and rotate later, the annotation rotates with the page (which is usually what you want), but if it's positioned near a corner, it might end up in a slightly different visual location than you intended. Best practice: settle the page orientation before signing.

How it works

Rotate PDF Pages in 4 steps.

01
Open the PDF
Drop your PDF onto the editor at /app or click to browse.
02
Find the page
In the Pages panel on the left, locate the page thumbnail you want to rotate.
03
Rotate
Hover the thumbnail — the rotate icon appears. Click to rotate 90° clockwise. Click again for 180°, 270°.
04
Download
Click Download. The exported PDF has the page rotation baked in as metadata; any viewer renders it correctly.

Frequently asked questions

Questions about this tool.

Yes. The rotation is stored as page metadata in the exported PDF (specifically, the `/Rotate` entry on the page object), so any PDF viewer — Acrobat, Preview, Foxit, browser-built-in, mobile reader apps — respects it and displays the page in the rotated orientation. Printers also respect it.

Click the rotate icon on any page thumbnail. The rotation persists in the exported file.
