This tool runs entirely in your browser using pdf-lib. Nothing is uploaded. Safe for Aadhaar, PAN, bank statements, and confidential documents.

Will the content be scaled or cropped?

Scaled. The content is scaled proportionally to fit within the new page size, maintaining aspect ratio. No content is cropped.

Can I convert Letter to A4?

Yes. Select A4 as the target size and click Resize. The tool works for any size conversion.

Are my files uploaded?

What if my PDF has mixed page sizes?

All pages are converted to the same target size. Each page's content is individually scaled to fit.
