How to rotate PDF
- Choose the PDF with pages facing the wrong way.
- Pick the rotation, and whether it applies to every page or only some.
- Press rotate. The corrected PDF downloads to your device.
How it works
Rotating a page in a PDF does not move any content. Each page carries a small piece of metadata called /Rotate, which tells a reader how far to turn the page clockwise before displaying it. Legal values are 0, 90, 180 and 270 degrees. This tool reads that number, adds your rotation to it, normalises the result back into that range, and writes it out again.
That design has a useful consequence: rotation is completely lossless and essentially instant, even on a 500-page document. Nothing is re-rendered and no pixels are touched, so file size barely changes and text remains selectable and searchable.
It also explains a common surprise. Because rotation is cumulative, applying 90° to a page that a scanner already marked as 270° gives you 0°, not 90°. If a page looks correct in one reader and sideways in another, the underlying rotation flag is usually the reason — and saving it through this tool bakes the correct value into the file for every reader.
The work happens in your browser. The file is read from disk into memory, the flags are edited by JavaScript running on your device, and the new bytes are handed back to you as a download. Nothing is transmitted.
A worked example
A colleague sends you contract-scan.pdf, 12 pages from an office scanner. Pages 1 to 11 are upright, but page 12 — the signature page, fed in sideways — appears rotated 90° counter-clockwise. You need to file it correctly.
Choose the file. Set the rotation to 90° clockwise, then change Apply to from Every page to Selected pages and type 12.
Press Rotate and download. You get contract-scan-rotated.pdf with a confirmation reading Rotated 1 page by 90°. Page 12 now displays upright in every reader, and the other 11 pages are untouched.
Here is the cumulative behaviour in practice. Page 12 started at /Rotate 270. Adding 90 gives 360, which normalises to 0 — upright. Had you guessed and applied 180° instead, you would have landed on 90° and the page would be sideways the other way. If that happens, do not start over: simply apply another rotation to the file you just downloaded until it looks right. Since the operation is lossless, there is no penalty for iterating.
Questions
How do I fix a page that is upside down or sideways?
Select it and choose 180 degrees for upside down, or 90 for a page scanned in landscape that should be portrait. The correction is written into the file, so it survives being emailed.
Does this change the page orientation permanently?
It writes the rotation into the page, which every reader obeys. The content itself is untouched, so nothing is re-encoded or degraded.
Does rotating a PDF reduce its quality?
No. Rotation only changes a metadata flag on each page; the page content is not re-rendered or re-compressed. The output is byte-for-byte identical in content and looks exactly as sharp as the original.
Why did the page not end up where I expected?
Rotation is cumulative on top of the value already stored in the file. A scanner may have written 90 or 270 degrees already, so your rotation is added to that. Just apply another rotation to the downloaded file until the page is upright — it costs nothing.
My PDF viewer lets me rotate already. Why use this?
Most readers rotate only the on-screen view and forget it when you close the file. This tool writes the rotation into the document itself, so it stays correct for whoever opens it next, including when it is printed or emailed.
Can I rotate only some pages?
Yes. Switch "Apply to" to "Selected pages" and enter a selection like 2, 5-7. Numbering starts at 1 and matches your PDF reader.
Is the file uploaded to a server?
No. There is no server. The page is a static file and the rotation runs in your browser, so the document never leaves your device. You can go offline after the page loads and it still works.
Will it work on a scanned document?
Yes. Scanned pages are images inside a PDF, and the rotation flag applies to them the same way it applies to text pages.
Does the file size change?
Only marginally. Saving rewrites the document structure, so the result may differ by a few kilobytes in either direction, but the page content itself is unchanged.
Can I rotate by an angle other than 90, 180 or 270?
Not through the rotation flag — the PDF specification only permits those values. Rotating by an arbitrary angle would mean re-rendering the page content, which is a different and lossy operation.
Can I turn a PDF that scanned in sideways?
That is exactly what this is for. Turn PDF pages 90 degrees either way, or 180 for one that came in upside down. You can rotate PDF files a page at a time rather than all at once, which matters for a scan where only some sheets went through the feeder the wrong way.
Can I rotate PDFs where only some pages are sideways?
That is the usual case with a scanner, and it is handled: turn PDFs a page at a time rather than all at once. Rotate PDF files individually or select only the pages that went through the feeder the wrong way.
