KissPDF Mirror a PDF Horizontally or Vertically
Create a mirror image of PDF pages or correct pages that already appear mirrored. Flip the PDF horizontally or vertically, then adjust individual pages before applying the changes.
The global controls set a direction across the document, while the controls on each thumbnail let you keep or remove that flip page by page.
KissPDF applies PDF coordinate transformations in browser memory instead of converting ordinary page content into screenshots.
Mirror or flip PDF pages in three steps.
Select the document containing pages that need to be mirrored.
Use a global direction, then toggle horizontal or vertical flipping on individual pages.
Create and download a new PDF using the state shown on every page.
Practical guide
Mirror PDF pages online by flipping them horizontally from left to right or vertically from top to bottom. Apply one direction to every page, then change individual page settings so a single PDF can contain mirrored, flipped, and unchanged pages without intentionally rasterizing ordinary content.
To mirror a PDF horizontally, flip its page content from left to right; ordinary text will read backward. A vertical PDF flip reflects content from top to bottom. Enable both directions on one page to turn its content through 180 degrees.
The global buttons write the chosen state to every PDF page. Each thumbnail still has its own horizontal and vertical controls, so you can remove or add either transformation on selected pages before choosing Apply changes.
Use horizontal mirroring for scans captured through a mirror or artwork prepared for transfers. Use vertical mirroring when content has been reflected across its top and bottom edge. If the page is merely sideways or upside down, Rotate PDF is usually the clearer operation.
KissPDF wraps selected page content in PDF coordinate transformations in browser memory. Page sizes, crop boxes, and ordinary vector drawing commands are retained, but rewritten annotations, links, forms, and digital signatures should be checked in the downloaded copy.
Clear answers based on how this tool actually works.
Select a PDF, choose Flip horizontally under All pages, turn that setting off on any pages that should remain unchanged, then choose Apply changes.
Yes. KissPDF mirrors PDF pages locally in your browser for free, with no signup or document upload.
Yes. Leave the global controls off and use the horizontal or vertical button next to that page only.
Flipping reflects content like a mirror. Rotation turns content without reversing the direction of text and images.
Yes. The two states are independent, and enabling both produces a visual 180-degree transformation of that page content.
No intentional rasterization is used for ordinary page content. Text and vector drawing commands remain PDF content.
No. Page previews and the transformed PDF are produced locally in your browser.
