How to Resize PDF Pages on Windows (A4, Letter, Custom)
Scale PDF pages to A4, Letter, or custom dimensions on Windows 10 or 11 in Chrome or Edge — no Acrobat, no software install.
Windows doesn't have a native PDF page resize tool. FixMyPDF's resize tool in Chrome or Edge on Windows lets you scale any PDF to A4, Letter, or custom dimensions — no Acrobat subscription, no software to install.
Open the Resize Tool in Chrome or Edge
Go to fixmypdf.in/tools/resize in Chrome or Edge on your Windows PC. Upload your PDF. The tool shows the current page dimensions.
Choose Target Size
Select A4 (standard in most of the world), Letter (US standard), A3, A5, Legal, or enter custom dimensions in mm or points. For PDFs shared between US (Letter) and international (A4) recipients, resizing to the recipient's standard avoids awkward print scaling.
Resize and Download
Click "Resize PDF" and the scaled PDF downloads to your Downloads folder. Open in Edge to verify — the page dimensions in Edge's Properties panel should show your target size.
Converting Letter PDFs to A4 on Windows
US PDFs (Letter 8.5"×11") sent to European or Asian recipients for printing often print with thin white borders on A4 paper. Resize to A4 first — the content scales 3% taller and narrows slightly, filling A4 correctly without leaving margins.
Resizing for Windows Print Driver Compatibility
Some Windows printer drivers scale PDFs unexpectedly when page size doesn't match loaded paper. Pre-resizing the PDF to match the printer's loaded paper size ensures WYSIWYG printing — what you see on screen is exactly what prints.
Custom Sizes for Non-Standard Windows Use Cases
Enter custom dimensions for trade show banners (A0, A1), architectural drawing sheets (ANSI B, ANSI D), or proprietary in-house document sizes. All in millimetres via the custom input.
After Resizing on Windows
Add page numbers to the resized document, compress for email, or add a password — all free in Chrome or Edge on Windows.
