KissPDF Resize PDF Pages
Make mixed PDF pages one consistent size for printing, publishing, or sharing. Complete pages are scaled proportionally and centered, so no content is cropped.
Uniform page dimensions make mixed documents easier to print, bind, publish, and review.
KissPDF changes page geometry in browser memory instead of uploading your document to a processing server.
Resize a PDF locally in four steps.
Choose one PDF from your device.
Select a paper preset or enter a custom width and height.
KissPDF fits and centers each complete page without cropping.
Save the resized copy while your original stays unchanged.
Practical guide
Resize every PDF page to one physical paper size without cropping the original content. Convert a PDF to A4, A3, A5, Letter, Legal, or a custom canvas while KissPDF fits and centers each complete page proportionally and keeps ordinary text and vector graphics sharp.
This tool changes physical page dimensions such as A4 or Letter. It does not target a number of kilobytes or reduce image resolution. Use Compress PDF when the download size is the problem.
KissPDF uses the complete MediaBox of each source page, scales it by the same amount horizontally and vertically, and centers it on the new page. This matches PDF2Go, including pages whose CropBox previously hid outer content. If the source and target proportions differ, white margins remain on two sides so that no page content is cut off or stretched.
Ordinary text, fonts, images, and vector drawing commands remain PDF content instead of being rasterized into page screenshots. Link and annotation coordinates are scaled with the page. The rewrite still changes page geometry, so signed and unusually interactive files require review. Unusual files with non-zero MediaBox origins follow PDF2Go coordinate behavior and can place some content outside the new page.
The selected PDF is read and resized in browser memory. KissPDF does not send the document bytes to a processing API, and it creates a separate download instead of changing the original file.
Clear answers based on how this tool actually works.
No. The complete visible source page is fitted proportionally inside the target page. Different proportions can create white margins instead of cropping.
Yes. Choose A4 and KissPDF applies the same A4 visual page size to every page, including mixed-size and rotated pages.
Not necessarily. This tool changes page dimensions, not image quality or target file size. Use Compress PDF for size reduction.
Ordinary text remains PDF text because the page is transformed rather than rasterized. Unusual PDF structures may still be normalized when saved.
The original page is scaled until it fully fits and then centered. White margins appear on the remaining sides.
No. Page resizing runs locally in your browser and the original file remains unchanged.
