Online PDF Resizer
Our free online PDF resizing tool allows you to change the physical paper dimensions of your PDF document. If you have a document formatted for US Letter size but need to print it on standard A4 paper, or if you want to standardize the page sizes of a mixed-dimension PDF, this tool provides a quick and accurate solution.
How to Resize PDF Dimensions
- Click the "Choose file" button to upload your PDF.
- Select your desired output paper size from the dropdown menu (such as A4, A5, US Letter, Legal, etc.).
- Choose whether you want the content inside the PDF to scale automatically to fit the new dimensions, or if you want to keep the content at its original size and only change the surrounding margins.
- Click "Resize PDF!" to process and download your updated file.
Does resizing reduce file size in MB?
No. This specific tool changes the physical dimensions of the pages (like changing the width and height of the paper). If you are looking to reduce the file size of your PDF in megabytes (MB) so it can be sent via email, please use our Optimize PDF tool instead.
