Rotate PDF 180 Degrees

This page opens the PDF rotator with a 180° turn preselected — the one-click cure for upside-down documents. Pages typically end up inverted when a paper stack is fed into an automatic document feeder the wrong way around, or when a duplex scan flips every back side; a 180° rotation puts them right side up again.

Rotate the whole file, or switch the scope to a page range such as 2, 4, 6 when only alternating pages are inverted — a common outcome of double-sided scanning. The page count appears immediately after you drop the file, and an impossible range is rejected with a clear message rather than producing a broken document.

Under the hood the tool updates each page's rotation flag with pdf-lib instead of redrawing the content, so the fix is lossless: fonts, images and vector graphics are untouched and the file stays the same size. Everything runs locally in the browser — no server, no queue, no watermark on the corrected PDF.
