PDF Page Rotator

How to Rotate PDF Pages
- Upload your PDF. Drag it onto the upload area or click to browse.
- Choose a mode. "All pages" applies the same rotation to every page — the most common case for upside-down scans. "Per page" lets you set a different rotation for each page individually.
- Set the rotation angle. 90° clockwise turns a landscape-sideways page back to portrait. 180° flips an upside-down page. 90° counter-clockwise is the opposite of clockwise.
- Rotate & save. Click the button to apply. The green banner confirms success.
- Download. Click "Download PDF" to save the rotated file.
Which Rotation to Choose
| Problem | Fix |
|---|---|
| Pages are upside down (180° wrong) | 180° |
| Portrait page rotated 90° clockwise (lying on its right side) | 90° counter-clockwise |
| Portrait page rotated 90° counter-clockwise (lying on its left side) | 90° clockwise |
| Landscape page that should stay landscape but is upside down | 180° |
| Mixed: some pages sideways, some upside down | Use Per page mode |
Frequently Asked Questions
Why are my scanned pages upside down?
Flatbed and multi-function scanners vary in which edge they treat as the top. If the document was placed face-down in a different orientation, all pages come out rotated 180°. Mobile scanning apps sometimes misread the device orientation. Rotating 90° clockwise or counter-clockwise fixes a portrait page that came out as landscape, and rotating 180° flips an upside-down document.
Does rotating change the page content or resolution?
No. A PDF rotation is a metadata change — the tool adds a rotation flag to each page object. The actual image or vector data inside the page is untouched. There is no quality loss and no re-rendering.
Can I rotate only specific pages?
Yes. Switch to "Per page" mode and set a rotation for each page individually. Pages set to "No change" are left at their current orientation. Per-page mode shows up to 30 pages; for longer documents use "All pages" mode.
What does "90° counter-clockwise" mean?
If you are looking at the page, 90° clockwise turns the bottom to the right. 90° counter-clockwise turns the bottom to the left. 180° turns the page upside down.
Are my files uploaded to a server?
No. Rotation is applied in your browser using the pdf-lib JavaScript library. Your file never leaves your device.
