How is this different from Compress PDF?

Compress PDF reduces file size (bytes). Resize PDF to A4 changes the physical page dimensions — useful when you need to print a US Letter PDF in A4 format or standardize page sizes across a document.

Will the content be cropped when resizing?

With "preserve aspect ratio" (recommended), content is scaled to fit within the target page with white margins. Without it, content is stretched to fill the target dimensions.

Which formats are supported?

You can resize to A4, A3, A5, US Letter (8.5 × 11 in), and US Legal (8.5 × 14 in).

Does this work for all PDF types?

Yes — the tool works for text PDFs, scanned PDFs, and mixed content PDFs. All pages are rescaled to the target format.
