Frequently Asked Questions
- What sizes can I choose?
- You can choose standard sizes like A4, A3, Letter, Legal, or specify exact dimensions.
- Is content scaled?
- Yes, content is proportionally scaled to the new page size.
- How do I change a PDF from A4 to A3?
- Upload your PDF, choose A3 as the new size and click Resize. The content scales up to the larger format automatically — and the same works the other way, e.g. A3 to A4.
- Can I resize a PDF without distorting the content?
- Yes. Content is scaled proportionally so text and images keep their relative sizes. If you switch between formats with different proportions, the content is centred on the new page.
- Can I set a custom page size?
- Yes, besides the standard formats you can enter exact dimensions if your document needs a special size — for print or particular displays.
- Is it free to resize a PDF?
- Yes, PDF.dk resizes PDFs online for free. Your file stays clean of watermarks, and you do not need an account.
- Is it safe to upload my PDF?
- Yes. Processing happens on servers in the Nordics, uploads are encrypted, and the file is removed automatically soon after. Nothing is stored or passed on.
