How to rotate pdf

  1. Drop the PDF. Every page is rendered as a thumbnail so you can see which ones are wrong.
  2. Turn the pages. Rotate all pages at once, or click individual pages to fix only what needs fixing.
  3. Save. The rotation is written into the file, so it opens correctly everywhere.

About rotate pdf

There is a specific irritation to a PDF that opens sideways. Your viewer will happily rotate it on screen, but that rotation is a view setting — it lives in the application, not the document. Send the file on and the recipient gets it sideways again. Print it and it comes out sideways. The fix has to be written into the file itself, which is what this tool does.

Rotation in a PDF is stored per page as a value of 0, 90, 180, or 270 degrees. The tool reads whatever each page already has, adds your change, and normalises the result, so rotating a page that was already at 90 by another 90 gives you 180 rather than an error. Because it is a property change rather than a re-render, the operation is lossless — no pixels are touched, nothing is recompressed, and the file size barely moves.

Mixed documents are the common case and the reason the tool renders thumbnails rather than asking you to type page numbers. A batch scan where the feeder grabbed three sheets the wrong way round needs those three fixed and the rest left alone. Click a thumbnail to rotate just that page. Use the rotate-all control when the whole document went through the scanner in landscape.

One thing worth knowing: rotation does not change the page dimensions recorded in the file, only the display orientation. A page that is 8.5 by 11 inches rotated to 90 degrees is still recorded as 8.5 by 11 with a rotation flag, and viewers handle that correctly. This is the standard behaviour and it is what makes the operation lossless. If you need pages physically resized rather than turned, that is a different job and this is not the tool for it.

Rotate PDF FAQ

Why does my PDF go back to sideways when I send it?

Because the rotation you applied was a view setting in your PDF reader, not a change to the file. This tool writes the rotation into the document so it travels with it.

Does rotating reduce quality?

No. Rotation is a page property, not a re-render. No image is recompressed and no text is rasterised, so the file is unchanged apart from the orientation flag.

Can I rotate only some pages?

Yes. Every page is shown as a thumbnail — click the ones that are wrong. The rotate-all control is there for when the whole document went through the scanner the wrong way.

Will the page size change?

No. A rotated page keeps its recorded dimensions and gains a rotation flag, which is how the PDF format is designed to work. Every standard viewer handles this correctly.

Is my file uploaded?

No. Rendering uses PDF.js and the rotation is written by pdf-lib, both running in this browser tab. No request carries your document anywhere.

Can I rotate a scanned PDF?

Yes, and it is the most common use for this tool. Scans have no text layer, but rotation works on the page regardless of what is on it.
