FAQ

About PDF Page Size to A4/Letter

Which target paper sizes are supported by PDF Page Size?

A4 and Letter are currently supported, together with a target orientation. This is useful for PDFs with inconsistent page sizes after merging files from different sources, inconsistent print scaling, or a mix of portrait and landscape pages.

What is the difference between Fit, Fill and crop, and Stretch?

Fit preserves all content but may leave blank space. Fill and crop covers the page but may remove edges. Stretch forces content into the target dimensions and can distort its proportions. For important charts or documents, avoid cropping and distortion when possible.

Can I resize only some pages?

Yes. You can set the page range. Before exporting, preview the first and last pages in the range, landscape pages, and pages with unusual dimensions to ensure scaling does not hide page numbers, seals, or edge content.

Can I process multiple PDFs in a batch?

Yes. Each file produces its own resized PDF, and batch results can be downloaded as ZIP. Processing takes place locally in your browser and does not consume a cloud trial or daily quota.
