Frequently Asked Questions (FAQ)

Is my file safe?

Absolutely. All processing is done locally in your browser. Your files are never uploaded to any server. After the site is loaded, feel free to disconnect from the internet!

What types of PDFs are supported?

Only standard PDF files are supported. Please ensure your file is a valid PDF.

Why are only vertical pages resized?

Horizontal pages are designed for wider formats and are left unchanged, while vertical pages are scaled down to fit the A4 format.

Many users face the challenge of inconsistent page sizes when combining several PDF files. Even when each document is originally created with A4 dimensions, the combined PDF can display pages at varying sizes on-screen, especially when merging scanned documents with digitally generated PDFs. PDF Combiner eliminates these issues by merging your PDFs and automatically standardizing every page to a uniform A4 size, ensuring a consistent, professional look throughout your document.
