Rotate PDF
Fix scanned pages that came out sideways — rotation is saved into the file.
How to fix a sideways PDF
- Drop your PDF onto the box or click to browse. The tool confirms the filename and page count.
- Choose the rotation: 90° clockwise, 180° for upside-down pages, or 270° for counter-clockwise.
- Leave the pages field empty to rotate the whole document, or enter a selection like 2, 5-7 to rotate only those pages.
- Click Rotate and download. The corrected file arrives as yourname-rotated.pdf.
A worked example: the half-sideways scan
A ten page scan came off the office copier with pages 4 and 9 rotated a quarter turn left, a classic result of one sheet fed sideways. Load the file, select 90° clockwise, type 4, 9 in the pages field, and click Rotate and download. The status line reports "Rotated 2 pages by 90°," and the download shows every page upright while pages 1 through 3, 5 through 8, and 10 are untouched. If you rotate the wrong direction by mistake, just load the downloaded file and rotate the same pages again; rotations stack, so a wrong 90° plus a 180° lands you at the correct 270°.
Why the fix sticks in every viewer
This tool does not rasterize or redraw your pages. It changes each selected page's rotation property, a standard field inside the PDF format that every compliant viewer honors, using the pdf-lib library running in your browser. The new angle is added to whatever rotation the page already carried, then normalized, so a page a previous tool had already turned is handled correctly instead of being blindly overwritten. Because the page content is untouched, text remains selectable, file size stays essentially the same, and quality cannot degrade. And since the whole operation happens on your device with no upload, rotating a contract or a medical record here exposes it to nobody.
Honest limitations
Rotation is limited to the three right angles. There is no small-angle deskewing, so a scan that is crooked by 2 degrees rather than 90 needs a scanner utility with straightening, since fixing that requires re-rendering the image, which this deliberately never does. There is no preview pane either; you pick pages by number, download, and check, which is fast in practice but means you need to know which pages are wrong before you start. Open the original in any viewer, note the page numbers, then come here. Password protected files usually fail to load, and if a stubborn viewer somewhere ignores the rotation property, that viewer is broken, but the practical fix is to print to PDF from a viewer that displays it correctly.
Frequently asked questions
Will the rotation stick when I share the file?
Yes. The rotation is written into each page's properties inside the PDF, so every viewer — Adobe, Preview, phones, browsers — shows the corrected orientation.
Can I rotate just some pages?
Yes. Enter a page selection like 2, 5-7 to rotate only those pages; leave it empty to rotate the whole document.
Which direction is 90°?
Clockwise. Use 270° for counter-clockwise, and 180° for upside-down pages.
