Resize PDF Pages

To resize a PDF online for free, upload your file into the dropzone above, choose a target paper format (such as A4 or US Letter) or input custom width and height dimensions, select Fit & Scale, and click Resize and Download PDF. The entire document is processed locally in your browser memory with zero server uploads.

Select US Letter (8.5 x 11 in) from the Standard Page Sizes dropdown or click the A4 → US Letter quick preset. Our tool applies proportional Fit & Scale to downscale page elements by ~6% and add balanced margins, converting international documents to North American Letter paper without clipping footers, headers, or page numbers.

To change PDF size to A4, choose A4 (210 × 297 mm) from the preset selector or click the US Letter → A4 chip. The tool automatically recalculates page geometry and scales content to international ISO 216 dimensions so your document is ready for global printing.

When scanning multi-source documents or merging files created in different software, pages often mix US Letter, A4, or legal dimensions. You can standardize all irregular pages by selecting your desired target size (e.g. A4 or Letter) with Apply to Pages: All Pages. The resizer normalizes every sheet to identical uniform dimensions.

Use the Fit & Scale (Proportional) fitting mode. Rather than cropping edges, Fit & Scale computes proportional scaling and centers content on the target canvas. This ensures print bleed margins are preserved and text along page borders is never trimmed by office printers.

Fit & Scale scales content proportionally to fit within target page boundaries without changing aspect ratios. Stretch to Fill forces content to stretch across both width and height, which may distort fonts and logos. Keep Original (Center) maintains 100% original scale and centers content on the new canvas, adding white margins or clipping overflow.

This tool resizes physical page dimensions (width and height in mm, inches, or points). If your goal is to decrease the file size of a PDF in megabytes (MB) for email or web upload, use our companion Compress PDF tool to downscale embedded images.

No. BrowserPowerToys utilizes native vector translation via pdf-lib Form XObjects. The document is never rasterized into lossy bitmap images. All typography, vector paths, form fields, and embedded high-resolution graphics retain their exact original vector sharpness and print resolution.

Yes. In addition to standard formats, our tool supports A0, A1, A2, A3, and US Tabloid / Ledger (11 × 17 in). Because vector paths are preserved, scaling up engineering schematics, CAD drawings, and poster prints maintains crisp line weights with zero pixelation.

In the Apply to Pages setting, choose Custom Range... and specify your target page numbers (e.g. 1, 3-5, 8). Selected pages are resized to your new target dimensions while all unselected pages remain in their original size and layout.

Our tool provides three orientation modes: Match Original detects each page's aspect ratio and keeps landscape slides landscape and portrait sheets portrait; Force Portrait standardizes all pages upright; and Force Landscape creates horizontal spreads. The live layout preview reflects your active orientation setting in real time.
