よくある質問
- How do I rotate PDF pages?
- Drop your PDF onto the page. You'll see thumbnails of every page with rotation buttons. Click to rotate individual pages 90° clockwise, 180°, or 270°. You can also rotate all pages at once with the bulk rotate option.
- Is there a file size limit?
- Free users up to 10 MB, Core subscribers up to 100 MB, Pro subscribers up to 200 MB.
- Is my PDF uploaded to a server?
- No. Rotation runs entirely in your browser using pdf-lib. Your file never leaves your device, and no account is required.
- Can I rotate different pages by different amounts?
- Yes. Each page has its own rotation control. Some scanners produce mixed-orientation PDFs (some pages portrait, some sideways) and this tool handles them per-page.
- Is this tool free?
- Yes — fully free with no account required.
- Does it work on mobile?
- Yes. The rotation tool works in any modern mobile browser.
- Does rotating reduce quality?
- No. Rotation just updates the page metadata — it doesn't re-render or re-encode anything. The output PDF is byte-equivalent in quality to the original.
