Increase the physical page canvas instead of squeezing the document into its original dimensions.
KissPDF changes page geometry in browser memory and creates a separate copy.
Use the PDF margin editor to expand every page in four steps.
Choose one PDF from your device.
Enter four values or drag the preview edges and corners.
Check the first page and the calculated output dimensions.
Create a new PDF with the same margins on every page.
Practical guide
Add margin to PDF pages online for free without shrinking the original content. This PDF margin adder inserts white padding around each page. Set separate top, right, bottom, and left margins from 0 to 3 inches, switch measurement units, or drag the first-page preview boundary.
Each side can use a different value. Link the four fields when the document needs an even white border, or keep them independent to create extra binding, punch, note, or stamp space on one edge.
KissPDF increases the physical page width and height, then moves the existing page content into the requested position. It does not scale the source artwork to fit inside the old paper size.
The workspace previews page one and applies the same visual top, right, bottom, and left measurements to every page. On rotated pages, KissPDF maps those visual sides to the underlying PDF coordinate system.
Content and common annotation coordinates are moved with the page. Changing page geometry still rewrites the PDF and invalidates digital signatures, so forms and unusually structured annotations should be reviewed after download.
Clear answers based on how this tool actually works.
No. KissPDF expands the page canvas and moves the original content. It does not scale the page content down.
Each top, right, bottom, or left margin can be up to 3 inches, which equals 76.2 mm, 7.62 cm, or 216 points.
Yes. Turn off Linked margins, then enter a value for only the edge that needs extra space.
Yes. Top, right, bottom, and left are independent after you turn off the Linked setting.
Yes. One set of visual margin measurements is applied to every page in the selected PDF.
The interactive workspace previews the first page. The page count and the same margin settings apply to the complete document.
Ordinary text remains PDF text because pages are translated rather than rendered as screenshots.
Common annotation coordinates are moved with the page, but unusual interactive PDFs should always be checked after download.
No. Adding margins changes page geometry and invalidates existing digital signatures.
No. The document is processed locally in your browser and saved as a separate file.
