Frequently Asked Questions

What does "Scale to Fit" mean?

Scale to Fit scales the page content proportionally so it fits entirely within the new page size without any cropping. There may be white space on the sides or top/bottom depending on the aspect ratio.

Can I resize only certain pages?

Currently the tool resizes all pages uniformly. Uncheck "Apply to all pages" to resize only the first page — per-page selection is coming in a future update.

Will it change the content of my PDF?

The visual content is scaled or repositioned according to your chosen scaling mode. No text or image data is removed — only the canvas dimensions and content transform change.

Is custom size in mm or pixels?

The custom dimension inputs use millimeters (mm), which are converted internally to PDF points (1 mm=2.835 pt) for precise, print-ready output.

Is my PDF uploaded to a server?

No — all processing is done locally in your browser using PDF-lib. Your document never leaves your device.

Resize PDF — Complete Guide

PDF resizing changes the page size of a PDF to standard formats like A4, A3, Letter, or custom dimensions. It ensures your document fits correctly when printing or submitting to systems that require a specific page size.

🖨️ Correct for printing

If your PDF was created in a non-standard size, resize to A4 or Letter before printing to ensure content fits correctly without cutting off edges.

📋 Submission requirements

Government portals, academic systems, and legal platforms often require documents in specific page sizes. Resize your PDF to meet these requirements instantly.

📄 Standardize documents

When combining PDFs of different page sizes, resize them all to a uniform size first for a consistent, professional-looking merged document.

📱 Mobile reading

Resize large-format PDFs (A3, Tabloid) to A4 or Letter size to make them more readable on laptop screens and tablet devices.

PDF page sizes are defined in points (1 point = 1/72 inch). Common sizes include A4 (595×842 pts), Letter (612×792 pts), and A3 (842×1191 pts). Resizing scales all page content proportionally to fit the new dimensions — maintaining layout and readability while matching your required output size.
