Free Online Rotate PDF
Fix sideways or upside-down PDF pages with a metadata-only rotation
Try these next
Page rotation is a quick fix, but scanned documents usually need more cleanup than just orientation. Adobe Acrobat lets you crop uneven margins, straighten skewed pages, and adjust the layout so the whole file looks clean and consistent. (We may earn a commission, at no cost to you.)
Why use Rotate PDF
- Fixes a whole batch of sideways scans at once -- no need to re-scan anything.
- Metadata-only operation. The /Rotate integer changes; content streams are untouched.
- Processes hundreds of pages in milliseconds.
- Reversible. Apply the complementary angle to undo.
- Works on phones, tablets, and desktops.
- Keeps the original filename so you don't lose track of which file you corrected.
How it works
Each PDF page stores its orientation in a /Rotate entry in the page dictionary (0, 90, 180, or 270 degrees). pdf-lib loads the document, iterates over every page object, reads the current /Rotate value (defaulting to 0 if absent), adds your chosen angle, and writes the result modulo 360 as the new value. No content stream is rewritten, no images are re-encoded, and no text coordinates are recalculated. PDF viewers read /Rotate at render time and rotate the entire page canvas accordingly. The modified document is serialized with pdf-lib's save() and downloaded.
About this tool
Scanned a batch of receipts and half came out sideways? Pick 90, 180, or 270 degrees and the tool corrects every page at once. The fix is instant because it's a metadata-only change -- the /Rotate value in each page dictionary gets updated without rewriting content streams or re-encoding images. Your document stays right here in the browser window. Text stays searchable, vector graphics stay sharp, fonts carry over, and hyperlinks keep working. Form fields, annotations, and bookmarks are unaffected. It's the same document, just oriented correctly. Need to undo? Apply the complementary angle. A 90-degree rotation reverses with 270 degrees. A 180-degree rotation reverses itself. The tool handles hundreds of pages in milliseconds because only a single integer per page changes. The output keeps the original filename for easy identification.
How to use Rotate PDF
- Drop your PDF. Drag the file onto the upload area.
- Pick the angle. Choose 90°, 180°, or 270° clockwise.
- Click Rotate and download. Every page rotates and the corrected file downloads.
Use cases
- Fixing a batch of scanned receipts that came through the automatic feeder sideways before filing them in an accounting system.
- Correcting landscape-oriented CAD site plans that export upside-down and need to display in portrait for a planning submission.
Frequently Asked Questions
Upload the file, pick 90, 180, or 270 degrees, click Rotate. Every page turns by that angle and the result downloads immediately.
This tool rotates every page by the same angle. For page-level control, split out the pages you need, rotate them here, then merge everything back together.
No. It updates a single metadata integer (/Rotate) in each page dictionary. Content streams, images, fonts, and links are untouched. The PDF viewer reads that integer and renders the page at the new angle.
Milliseconds. A 500-page file processes just as quickly as a 5-page one because the tool modifies one number per page -- no content is re-encoded.
Apply the opposite angle. 90° reverses with 270°. 180° reverses itself. The original content is never altered, so there's no degradation from rotating back and forth.
