PDF Resize Tool
AIfreeforever's PDF Resize tool lets you change PDF page dimensions to any standard or custom size directly in your browser. Just upload your PDF, pick a target size like A4 or Letter, choose the orientation, and your resized document will be ready in seconds. You get complete control with four specialized modes: Page Resize for standard formats, Custom Resize for exact dimensions, Fit to Page for intelligent scaling, and Batch Resize for handling multiple files at once. Since everything runs locally on your device, your documents stay completely private.
Page Resize
Easily convert PDF pages to standard formats like A4, Letter, or Legal in both portrait and landscape orientation.
Custom Resize
Define exact page dimensions in millimeters, inches, or points to handle banners, brochures, or custom packaging formats.
Fit to Page
Intelligently scale your content to fit target sizes using Fit, Fill, or Stretch modes to manage different aspect ratios.
Batch Resize
Process multiple PDF files at once and resize them all to the same target dimensions with real-time progress tracking.
Resize PDF Pages to Standard and Custom Sizes
Dealing with mixed-format PDF collections is a common headache when documents come from various sources or software. You can fix that easily with this tool by standardizing your pages in just a few clicks. Pick from eight standard paper sizes or enter your own specific dimensions using the Custom Resize mode. If you enable the Scale content to fit option, your content will automatically reposition and scale to fit the new page boundaries so nothing gets clipped.
Convert Between A4 and Letter with One Click
Most people use this tool to jump between A4 (210 x 297 mm) and US Letter (8.5 x 11 inches). Simply select your target format, turn on the scaling option, and hit Resize. You don't have to worry about the math because the tool calculates the correct ratios and centers everything for you. Your text remains perfectly sharp since the tool only adjusts page coordinates without touching the font data.
Set Custom Dimensions in mm, Inches, or Points
If a standard preset doesn't quite fit your needs, Custom Resize lets you type in any width and height you want. You can use millimeters for metric precision, inches for US standards, or points for design work. Feel free to switch units anytime; the tool handles all the conversions internally to ensure there are no rounding errors.
Online PDF Resize with Batch Processing
While one-by-one resizing is fine for quick fixes, batch processing is a real lifesaver when you have a mountain of documents to standardize. Our Batch Resize mode lets you drag in as many PDFs as you need and process them all with a single click. Every file has its own status indicator and download button, allowing you to grab your results as soon as they are ready without waiting for the whole batch to finish.
Scale Content with Fit, Fill, and Stretch Modes
Fit to Page does more than just resize the page box; it intelligently scales your content too. You can choose Fit mode to keep everything visible with small margins, or use Fill mode to cover the entire page which is perfect for posters where you want to avoid white borders. If exact coverage matters more than proportions, Stretch mode will map your content directly to the new dimensions regardless of the original aspect ratio.
Portrait and Landscape Orientation Control
You can apply any standard size preset in either portrait or landscape orientation with a quick toggle. When you switch orientations, the tool automatically swaps the width and height so you always get the right dimensions without manual math. This is a huge help when you are standardizing a mixed batch of scanned documents where some pages might be sideways.
Free PDF Resize Tool with Complete Privacy
Your PDF files often contain sensitive business or personal info that shouldn't be uploaded to a random server. That is why this tool processes everything right inside your browser tab using local JavaScript. Your PDF loads into memory, gets resized locally, and the finished file is saved directly to your device. Nothing ever leaves your computer, nothing is stored, and you don't even need an account.
No Account, No Upload, No Storage
All four resize modes are ready to use the moment you land on the page with no sign-up required. Your files only exist in your browser's temporary memory while you are working and vanish as soon as you close the tab. You won't find any watermarks on the output, and there are no limits on file size or page count to worry about.
Client-Side Processing for Document Security
Since everything happens locally in your browser, your documents never travel across the internet. You can resize contracts, financial reports, or medical records with full confidence that your private information stays private. Every resized PDF you download is built entirely on your own hardware.
