Does rotating by an odd angle rasterize my PDF?

No. The rotation is applied as a transformation matrix on the page's content stream — text, vectors and images keep their original form. Text remains selectable and searchable, and images keep their resolution.

Why does the page get bigger after rotation?

A rectangle rotated by a non-right angle needs a larger bounding box to contain its corners. The tool grows the MediaBox and CropBox to fit, so rotated content is never clipped.

Can I rotate different pages by different angles?

Yes. Each page has its own angle field on the thumbnail grid. Use the batch control to set a starting angle for all pages, then adjust individual pages.

What about negative angles?

Negative values rotate counter-clockwise — -15° is the same as 345°. Both are accepted.

Do links and annotations survive?

Yes. Link rectangles and highlight quads are transformed by the same rotation as the page content, so they land in the right place.

Is my file uploaded anywhere?

No. All processing happens locally in your browser with pdf-lib — nothing is sent to a server.

PDFを任意の角度で回転：傾いたスキャンを無料で補正

1. Upload a PDF

Drop in the document with the tilted or sideways pages — a skewed scan, a rotated chart, a landscape table.

2. Set the angles

Type any degree per page, or apply one angle to the whole document. The thumbnails show the result live.

3. Download

Get a PDF whose page boxes grew to fit the rotated content — nothing rasterized, text still selectable.

Rotate PDF Pages by Any Angle, Not Just 90°

Why 90° steps aren't enough

Every PDF tool can rotate a page by 90 degrees — that fixes a landscape scan saved as portrait. But the rotations people actually need are rarely that tidy. A page fed through a scanner at a slight tilt comes out crooked by 3° or 7°. A chart pasted sideways into a report sits at an odd angle. A signature photo lands at 15° off vertical. For all of these, 90° steps do nothing — you need arbitrary-angle rotation.

This tool rotates any page by any whole-degree angle, clockwise or counter-clockwise. Set one angle for the entire document, or fine-tune individual pages on the thumbnail grid — each thumbnail previews its rotation live, so you can eyeball a deskewed scan until the text lines up.

What happens to the page

Rotating by a non-right angle changes the page's shape: a 612×792 pt page rotated 30° needs a wider, taller box to hold its corners. The tool grows each page's MediaBox and CropBox to fit the rotated content, so nothing is clipped and no white bands appear. Annotations move with the page — link rectangles and highlight quads are transformed by the same rotation matrix.

The rotation is vector math, not a screenshot. Text stays text (selectable, searchable, copyable), vector lines stay sharp at any zoom, and images keep their original resolution. The file size barely changes — a few operators per page, no re-encoding.

What you can do

Arbitrary rotation covers the cases fixed-angle tools can't.

Any whole-degree angle

1° to 359°, clockwise or counter-clockwise — deskew a 4° tilt or flip a page 180°.

Per-page or batch

Apply one angle to every page, or set each page individually on the thumbnail grid.

Live preview

Thumbnails rotate as you type the angle — see the result before you commit.

Private by design

Everything runs in your browser. The file never leaves your device.

Deskewing vs. rotating

If your pages are scanned and uniformly tilted, our Deskew PDF tool detects the angle automatically. Use this tool when you know the angle, when different pages need different corrections, or when the tilt is in the content rather than the scan — a rotated diagram inside an otherwise straight page. For pure 90° orientation fixes, Rotate PDF is the faster path.
