What does Fix Page Size do?

It normalizes all pages in a PDF to the same target size. Choose a standard size (A4, Letter, etc.) or set custom dimensions, then pick how the content fits: scale, crop, or center.

Is my PDF uploaded to a server?

No. Everything runs in your browser. Nothing leaves your device.

What’s the difference between scale, crop, and center?

Scale fits the whole page inside the target with possible whitespace. Crop fills the target completely but may clip edges. Center places the page at its original size in the center of the target without scaling.

What sizes are available?

A4, US Letter, US Legal, A3, A5, and custom dimensions in PDF points.

Does it work with password-protected PDFs?

Yes. Enter the password when prompted. Processing happens locally.

Will this change the content of my pages?

The content stays the same. Only the page canvas size and positioning change based on the fit mode you select.

Can I process multiple files at once?

Yes. Drop in multiple PDFs and the tool applies the same size settings to all of them.

About Fix Page Size

How Page Size Normalization Works

PDFs can have pages of different sizes within the same document. A scanned letter-size page next to an A4 page next to something oddly sized. Fix Page Size makes every page the same standard size.

OxygenPDF offers three fit modes: scale (fit entire page with whitespace), crop (fill the target size, clipping edges), or center (no scaling, just center the original). Pick your target size — A4, Letter, Legal, A3, A5, or custom — and apply.

Why Normalize Page Sizes

Mixed page sizes cause real problems. Printers choke, viewers jump around, and professional output looks sloppy.

Print Consistency

Printers expect a uniform page size. Mixed sizes cause paper tray switches, alignment issues, and wasted sheets.

Corporate Standards

When merging documents from different sources, normalize to your company’s standard page size before distribution.

Regional Conversion

Convert US Letter to A4 or vice versa when sharing documents internationally. Readers in different countries expect their local standard.

Post-Merge Cleanup

After merging PDFs with different page sizes, run them through here to make the combined document uniform.

How It Compares

Page size normalization is an advanced feature. Many tools skip it entirely.

Three Fit Modes

Scale to fit shrinks or stretches each page so the entire content fits within the target dimensions. If aspect ratios don’t match, you’ll see whitespace on the sides or top/bottom. Nothing gets clipped.

Crop to fill scales each page to completely cover the target dimensions. Content at the edges may be cut off, but there’s no whitespace. Center places the original page in the middle of the target size without any scaling — useful when you just want consistent dimensions without distorting content.

Built for Files You Can’t Share

Normalizing page sizes usually happens as part of document preparation for printing or distribution. The content could be anything.
