Frequently Asked Questions
Does resizing a PDF change its content?
No — resizing only changes the page dimensions. Text, images, and layout are scaled proportionally (or stretched, if you choose Fill) to match the new page size.
Can I convert a Letter-size PDF to A4?
Yes. Upload your Letter PDF, choose A4 as the target size, and download — this is one of the most common uses for this tool when sharing documents internationally.
What's the difference between Fit and Fill?
Fit scales your content to stay within the new page size while preserving its aspect ratio, adding margins if needed. Fill stretches content to exactly cover the new page, which may distort the aspect ratio.
Does resizing change the file size too?
Not directly — resizing changes page dimensions, not compression. If you also need a smaller file, run the output through our PDF Compressor afterward.
Will my PDF pages keep the same orientation?
By default, yes — the 'Keep' orientation option preserves each page's portrait or landscape orientation at the new size. You can also force portrait or landscape for every page.
Will text stay sharp after resizing?
Yes. PDF pages contain vector text and graphics, not pixels, so resizing scales the underlying vectors rather than rasterizing them — text stays crisp at any size.
