How do I change PDF page size to A4 or Letter?

Upload your PDF to PDFuck, select the target page size (A4, Letter, Legal, A3, A5, Tabloid, etc.), choose whether to scale content to fit the new size, and click Apply. All pages are resized instantly in your browser.

What standard page sizes are supported?

PDFuck supports all common standard sizes: A4 (210×297mm), A3 (297×420mm), A5 (148×210mm), Letter (8.5×11in), Legal (8.5×14in), and Tabloid (11×17in). These cover virtually all printing and document standards worldwide.

Will resizing affect the quality of my PDF content?

Text and vector graphics remain perfectly sharp at any size. Image quality depends on the original resolution — scaling up may reduce apparent sharpness, while scaling down preserves or improves quality.

Can I scale content to fit the new page size?

Yes. You can choose to scale content proportionally to fit the new dimensions, or maintain the original content size within the new page boundaries. Scaling ensures nothing is cropped or cut off.

Are all pages resized to the same size?

Yes. The resize tool adjusts all pages in the document to the same target size for uniform output. This is ideal for standardizing documents with mixed page sizes into a consistent format.
