PDF Rescale & Resizer Online Tool

How to Resize a PDF

1. Drop your PDF onto the tool, or click Choose PDF File.
2. Pick an Output Size. The buttons are A4, A5, A3, Letter, Legal, Tabloid, 4x6, 5x7 and Custom. With Custom, type a width and height in millimeters.
3. Set the Orientation. Portrait and Landscape force every page to that shape. Auto follows each page's own orientation.
4. Choose a Fit Mode. Fit shows the whole page with its proportions kept. Fill covers the whole sheet and may crop the edges. Stretch fills the sheet exactly and ignores the proportions.
5. Add Page Margins in millimeters and pick a Background Color if you want one. Use Prev and Next to check other pages in the Live Preview.
6. Choose Render Scale and Output Quality, then click Export Rescaled PDF. The file is saved with _rescaled added to the name.

Why Use This PDF Resizer

• Your file stays on your device. The pages are resized by code running in your browser. Nothing is sent to a server.
• Standard and custom sizes. Paper sizes, photo sizes and any width and height from 10 to 2000 mm.
• Three fit modes. Keep the whole page, fill the sheet, or stretch to an exact shape.
• Live preview with sizes. Flip through the pages and compare the original size with the output size before you export.
• Margins and background. Leave a border around the content and fill the empty space with a color.

Good to know: every page is redrawn as a JPEG image, so text in the new file can no longer be selected or searched, and links stop working. Fill crops whatever does not fit, and Stretch distorts the page if its shape differs from the target. A higher Render Scale and Output Quality give sharper pages and a bigger file. To trim a page instead of resizing it, use Crop PDF.

FAQ

How do I change a PDF to A4 size?

Drop your PDF onto the tool, keep A4 selected, choose Fit so nothing is cut off, and click Export Rescaled PDF. Every page is placed on an A4 sheet.

What is the difference between Fit, Fill and Stretch?

Fit scales the page until it fits inside the sheet, keeping its proportions, so you may see empty bands. Fill scales it until the sheet is covered, which can crop the edges. Stretch pulls the page to the exact sheet shape and can distort it.

Will wide pages be turned sideways?

Only if you choose Auto. With Portrait or Landscape, every page gets that orientation, and a page of the other shape is scaled down to fit inside it.

Will the text in my PDF still be selectable?

No. Each page is redrawn as an image, so the new file has no selectable or searchable text. Keep the original if you need that.

Why is my resized PDF bigger than the original?

Pages are saved as images, and a higher Render Scale (up to 3x) and Output Quality (up to 95%) mean more detail and more bytes. Standard (1.5x) with 75% quality gives a smaller file.

Is my PDF uploaded anywhere, and is there a size limit?

No, the PDF stays on your device while it is processed in your browser. Your file size limit is shown on this page, and a free account raises it.
