支持的格式

输入格式

PDF (any version, including scanned)

输出格式

PDF (rotated)

Rotation updates the page orientation metadata without re-encoding any content. File size remains nearly identical to the original.

示例

Fix an upside-down scanned document

Rotate all pages 180° to correct a document that was scanned upside-down.

输入

Scanned PDF with all pages upside-down

输出

Corrected PDF with all pages right-side up

Fix alternating landscape pages in a double-sided scan

Rotate even pages 90° to correct alternating orientation from a double-sided scan.

输入

Double-sided scan with alternating portrait/landscape pages

输出

PDF with consistent portrait orientation on all pages

Rotation angle is applied in the wrong direction

解决方案

All angles are clockwise. Use 270° to achieve a 90° counter-clockwise rotation.

常见问题

我可以只旋转部分页面吗？

可以——全部、奇数页或偶数页。

原文件会被修改吗？

不会。会下载一个新文件。

What rotation angles are available?

Three angles are supported: 90° clockwise, 180° (upside down), and 270° clockwise (equivalent to 90° counter-clockwise). All angles are applied in the clockwise direction.

Can I rotate a scanned PDF?

Yes. Scanned PDFs consist of image pages embedded in a PDF container. Rotation updates the page orientation flag in the PDF structure, and the scanned images display correctly in any PDF viewer after rotation.

Does rotation affect text searchability?

The embedded text layer and font data are not modified. Most PDF viewers display searchable text relative to the page orientation, so text should remain searchable after rotation.

Can I rotate a password-protected PDF?

No. The PDF must be unlocked before any modifications can be applied. Use the Unlock PDF tool first, then rotate the resulting unprotected file.

What is the difference between rotating odd and even pages?

When a document is scanned double-sided with an automatic feeder, every other page is sometimes captured upside-down. Rotating only odd or even pages corrects the alternating orientation without affecting the correctly-oriented pages.

Will the file size change after rotation?

Rotation adds only a few bytes of orientation metadata to each page. The output file size is virtually identical to the original — no re-encoding occurs.
