One PDF per run; extra dropped files are ignored.
Use all, *, 4, 2-5, 7-, odd, even, portrait, or landscape.
Existing saved rotation is preserved and combined with this turn.
The source file is never overwritten.
Preserve is neutral: opening Advanced without changes does not alter the rotation plan.
The neutral maximum is 700 selected pages.

A PDF page can open sideways even when its text and images are intact. In many cases the correction is a saved page rotation, not a crop or a new scan. PDF viewers apply that rotation in 90-degree steps when displaying or printing the page, while the underlying page box and content remain in the document.

This distinction matters for mixed packets. A scanner may save most pages upright and one landscape insert sideways; a merged file may already contain 90-degree rotations on selected pages. Applying another turn must be combined with each page's existing angle rather than assuming every page begins at zero.

  • Clockwise 90 degrees moves the top edge to the right.
  • Counterclockwise 90 degrees is stored as a 270-degree clockwise turn.
  • Flip 180 degrees turns an upside-down page without changing portrait versus landscape shape.

Page rotation does not deskew a slightly tilted scan, reorder pages, change printed page labels, perform optical character recognition, or crop margins. Saving a modified PDF can also affect digital signatures and complex document features, so a corrected copy should be verified before it replaces an authoritative original.

How to Use This Tool:

Load one local PDF, select page positions, and save a new copy with combined quarter-turn angles.

  1. Choose a PDF of up to 150 MB and 700 pages. Encrypted, malformed, empty, or unsupported files may not load.
  2. Enter Pages to rotate using all, *, a page such as 4, a range such as 2-5 or 7-, or the selectors odd, even, portrait, and landscape.
  3. Choose a clockwise 90-degree turn, counterclockwise 90-degree turn, or 180-degree flip. Review the selection label and any duplicate or clipped-range warning before rotating.
  4. Keep Document metadata on Preserve unless a generic title or a title based on the source filename is intended. Lower the selected-page guard when a large accidental selection should stop the job.
  5. Open the downloaded copy in a PDF viewer and inspect changed pages, forms, bookmarks, accessibility structure, and signature status before distribution.

Interpreting Results:

The page map is the clearest scope check. For every page it shows whether a turn was applied, the saved source angle, and the final angle. A final angle of 0 does not mean no work occurred; an existing 270-degree rotation plus a new clockwise 90-degree turn correctly returns to 0.

The portrait and landscape selectors use the page box dimensions, with equal width and height treated as landscape. They do not adjust that classification for an existing saved rotation. Confirm the resulting page list when the source already contains rotated pages.

Technical Details:

PDF page rotation is expressed as a multiple of 90 degrees. The operation reads each page's existing saved angle, applies the selected quarter-turn only to matched page positions, reduces the sum modulo 360, and writes the final angle into the new document.

Formula Core

For original angle r and applied turn a, the final saved angle is:

rfinal=(roriginal+a)mod360°

The applied turn is 90, 180, or 270 degrees for selected pages and 0 for every other page. Only source angles equivalent to 0, 90, 180, or 270 degrees are accepted.

Transformation Core

SelectorRule
all or *Select every one-based page position.
odd or evenSelect page positions by parity.
4, 2-5, 7-Select one page, an inclusive range, or from the start page through the final page.
portraitSelect pages whose box width is less than box height.
landscapeSelect pages whose box width is greater than or equal to box height.

Comma-separated selectors are combined into one sorted set. Duplicate matches are applied once and produce a warning. A range ending beyond the document is clipped with a warning, but a range that starts after the last page, descends, uses zero, or contains unsupported syntax is rejected. The plan also stops when the matched count exceeds the selected-page guard.

Preserve mode makes no explicit changes to title, creator, or producer metadata. Neutral mode sets a generic title and identifies the rotator as creator and producer; source-name mode sets a title from the source filename and the same creator and producer. Neither option promises to remove every other metadata field.

The PDF is parsed and serialized as a new file. Page content is not rasterized, and the source is never overwritten, but rewriting can invalidate digital signatures or expose compatibility problems in forms, bookmarks, tags, page labels, annotations, or unusual object structures. Password entry is not supported.

Privacy Notes:

The source bytes, page geometry, rotation plan, and generated PDF remain in the current browser session and are not uploaded. Non-file settings may be carried in the page address, but the selected document and generated bytes are not. Close or reload the page to discard them.
