Fix Upside-Down PDF Pages

Upside-down pages in PDFs are a common result of scanning paper documents placed face-down on the scanner glass, or exporting from certain apps that misread the document orientation. Instead of re-scanning, you can fix the orientation in seconds.

Select "All pages" and a 180° rotation to flip the entire document right-side up. If only some pages are inverted, list those specific page numbers in the pages field and apply the 180° rotation to just those.

The rotation is a metadata operation in the PDF — the content is not re-rendered or rasterized. Text remains selectable, vector graphics remain crisp, and the file size does not increase significantly.

Everything runs locally in your browser using pdf-lib. No upload required.
