How to rotate a PDF by a few degrees

↻ 1. Why rotate a PDF by a few degrees?

Sometimes a PDF page is not upside down or sideways — it is simply a little crooked. In that case, rotating it by 90 degrees is useless.

The custom rotation feature in 123 PDF Editor PRO lets you rotate selected pages by a precise angle such as 2°, 5°, 10° or 15°.

• ✓ Straighten slightly crooked scanned pages.
• ✓ Correct PDFs created from photos taken at a slight angle.
• ✓ Align forms, receipts, notes and archived documents.
• ✓ Apply the same correction to several selected pages at once.

1 2. Open the PDF

Start by loading the document you want to straighten in 123 PDF Editor PRO.

1. Launch 123 PDF Editor PRO.
2. Click Choose a PDF.
3. Select the document from your computer.
4. Wait for the pages to appear in the editor.

☰ 3. Open Page Organizer

Custom page rotation is available in Page Organizer, where all document pages are shown as thumbnails.

From this screen you can also reorder, delete, duplicate, extract and organise pages, so it is a convenient place to fix the whole PDF before exporting it.

✓ 4. Select the page or pages to straighten

Select the page that needs correction, or select several pages if they all have the same tilt.

This is useful for scanned documents where a batch of pages was captured at the same slight angle.

↻ 5. Apply a custom rotation angle

Instead of being limited to quarter-turn rotations, you can enter a precise angle for the selected pages.

For example, you might use:

• ✓ 1°–2° for a very small alignment correction.
• ✓ 5° for a visibly crooked scan.
• ✓ 10°–15° for a more noticeably tilted page.

The content is rotated inside the page so you can correct the angle without changing the whole document to portrait or landscape orientation.

👁 6. Check the result before finishing

After applying the rotation, check the updated page preview and make sure text lines, borders and images now look straight.

If the page is still slightly tilted, simply adjust the angle again until the content is properly aligned.

This makes custom rotation especially useful for scanned PDFs, where the ideal correction may be only a few degrees.

↶ 7. Undo or reset the rotation

You can experiment with different angles without having to reload the original document.

• ✓ Use Undo to reverse the latest change.
• ✓ Use Reset Rotation to return the selected pages to their original rotation.

This is useful when you are trying several values to find the most accurate correction.

⇩ 8. Download the corrected PDF

Once the pages are straight, apply the changes and save the corrected document.

1. Review the rotated pages in Page Organizer.
2. Confirm the modifications.
3. Return to the main editor if you need to make any other changes.
4. Click Download PDF.

You can continue editing before downloading: add text, images, signatures, annotations, page numbers, headers, footers and other elements if needed.
