What happens when you mirror a PDF?
This diagram shows a horizontal mirror: the entire page is reflected, including its text. Use rotation instead if your page is sideways and you want its writing to remain readable.
A vertical mirror reverses top and bottom. Both options keep the page dimensions. Downloaded pages remain PDF content rather than screenshots; check links, forms, and annotations separately because page embedding may not preserve them.
What this tool does
Mirror PDF reflects every page of a PDF left-to-right or top-to-bottom. Use horizontal mirroring to reverse a scan or prepare mirrored artwork; use vertical mirroring to reverse the page from top to bottom. Text is reflected along with images and shapes. Preview the result and download a new PDF while keeping the original file unchanged.
How it works
The toolkit uses pdf-lib locally in your browser. Each original page is embedded into a new same-size PDF page and drawn with a negative scale transform, so the document is mirrored without rasterizing pages or uploading files.
When to use Mirror PDF
Mirroring scanned PDF pages that need to be reversed
Creating a left-right or top-bottom mirrored PDF copy
Working locally without installing software
Keeping the original PDF unchanged while exporting a transformed copy
FAQ
Is mirroring the same as rotating a PDF?
No. A mirror reflects the page and reverses its writing. Rotation turns the page 90 or 180 degrees without reflecting the letters. Use Rotate PDF to fix sideways pages.
Does mirrored text stay readable?
The text is reflected with the rest of the page, so a horizontal mirror produces backward writing. Review the preview before downloading, especially if you are preparing a file for printing.
Will PDF forms, links, and comments be preserved?
The tool embeds each original page into a new PDF page. Interactive form fields, links, annotations, and document-level features may not carry over. Keep your source file and check the output if those features matter.
Does this flatten or rasterize the PDF?
No. It applies a PDF page transform using pdf-lib and keeps the output as a PDF.
Are my files uploaded anywhere?
No. Everything runs in your browser and your files never leave your device.
