Scanned Documents: Fix orientation of documents that were scanned upside down or sideways. Perfect for correcting scanner errors where pages were fed incorrectly, making documents readable without having to tilt your screen.
Mixed Orientation PDFs: Correct PDFs with both portrait and landscape pages. Great for presentations, reports, or documents where some pages need to be rotated to match the rest of the document's orientation.
Photo to PDF Conversions: Rotate pages after converting photos to PDF. Useful when phone photos were taken in landscape but appear sideways in the PDF, requiring 90° or 270° rotation.
Document Sharing: Ensure all pages have correct orientation before sharing with colleagues or clients. Professional documents should display correctly without requiring readers to rotate their devices.
Is This For You?
Anyone with a PDF page (or an entire document) that opens sideways or upside down — scanned pages fed into the scanner wrong, a phone photo converted to PDF in the wrong orientation, or a landscape page mixed into an otherwise portrait document.
When a page is genuinely turned 90°, 180°, or 270° from where it should be — the content itself is readable if you tilt your head a quarter or half turn. Use it before sharing, printing, or archiving so every reader sees the page right-side up without rotating their own screen.
If a page is only slightly tilted — a few degrees crooked from an imperfect scan feed, not fully sideways — this tool won't help, since it only turns pages in fixed 90° steps. That's a job for PDFcrest's Deskew PDF tool, which straightens small-angle skew instead.

Workflow Recipes
Rotating is rarely the only step — here are the tool combinations PDFcrest users chain together most often.
Some scanners feed the even-numbered pages of a duplex scan upside down. Rotate just those pages right-side up, then recombine the odd and even batches into one correctly ordered document.
Fixed the orientation of a scanned document? Insert a blank divider or cover page next, so the file is ready to print or bind.
Straighten out a sideways scan first, then invert its colors for a dark-mode-friendly version that's easier to read on screen at night.
Fix the orientation of an entire multi-page document in one pass, then split out only the pages you actually need to share.
A stack of pages scanned back-to-front, each one also upside down? Rotate every page right-side up, then flip the page order back to normal.
Under the Hood
No black box — this is the real per-page rotation math this page runs, taken directly from assets/js/rotate-pdf.js.
Per click, per page (in the browser, before you submit):
pageRotations[i] = (pageRotations[i] + 90) % 360
On "Apply Rotations & Download" (via pdf-lib):
existingRotation = page.getRotation().angle // whatever /Rotate value the PDF already had
newRotation = (existingRotation + pageRotations[i]) % 360
page.setRotation(PDFLib.degrees(newRotation)) // writes the page's /Rotate entry
| Signal | What it actually does |
|---|---|
pageRotations[i] | One integer per page, starting at 0. Each click of that page's rotate button adds exactly 90 and wraps at 360 — so clicking once gives 90°, twice gives 180°, three times gives 270°, a fourth click returns to 0°. There is no arbitrary-angle or freehand rotation; only fixed 90° clockwise steps. |
Rotate All | Loops over every page and adds 90° to each one's current value in a single click — it bumps every page by the same fixed 90° step, it does not let you pick one target angle and apply it to all pages at once. |
page.getRotation().angle | The rotation already stored in the source PDF's page dictionary (most pages start at 0°, but some scanner output or prior edits carry an existing value). PDFcrest adds your chosen rotation on top of this rather than overwriting it, so the final angle is always relative to how the page already opens. |
page.setRotation() | A pdf-lib call that writes the page's standard PDF /Rotate dictionary entry. This is a metadata-level change, not a pixel redraw — the page's text and vector content are never re-rendered or re-rasterized, so nothing loses sharpness no matter how many times a page is rotated. |
/Rotate key), not an image transform, rotating a text-based PDF never degrades its quality or removes its selectable text — unlike tools that flatten pages to images to achieve rotation.Everything you need to know about rotating PDF pages

PDFcrest saves rotation permanently. After rotating and downloading, your PDF will maintain the new orientation when opened in Adobe Reader, Preview, or any PDF viewer.
Upload your PDF to PDFcrest, rotate each page to the correct angle using the visual preview, then click Download. The rotation is permanently written into the PDF file — not a temporary view setting. Every PDF reader will open it at the correct orientation automatically, without you needing to rotate it again.
Click the rotate button once on any page to rotate PDF 90 degrees clockwise. Click twice to rotate PDF 180 degrees (upside down to right-side up). Click three times for 270 degrees. Use the "Rotate All" button to apply the same rotation to every page at once, or rotate individual pages one by one using the per-page controls.
Upload your PDF to PDFcrest and rotate the landscape-oriented pages 90° clockwise or counter-clockwise until they appear portrait in the visual preview. This is the fastest way to change PDF orientation from landscape to portrait (or portrait to landscape). The orientation change is permanently saved in the downloaded file.
PDFcrest is the best free PDF rotator online because it permanently saves rotation, provides a visual page-by-page preview before download, lets you rotate individual pages or all pages at once, requires no signup or watermarks, and works on all devices including iPhone, Android, Mac, and Windows — unlike ilovePDF or SmallPDF which limit free use.
This happens when rotation is saved as a viewer preference rather than embedded in the file — some tools only rotate the display, not the file itself. PDFcrest permanently embeds the rotation into the PDF data, so the file will open correctly in any reader on any device without reverting to the original orientation.
