Guide
About Resize Pages
Documents from different countries mix A4 and US Letter, which causes awkward printing and cut-off edges. Resizing converts every page to one standard size so the document prints correctly anywhere.
Content is scaled uniformly and centered, never stretched. Because scaling is mathematical, text and vector graphics stay perfectly sharp, and links keep pointing to the right places.
Tips for best results
- “Keep each page's orientation” preserves landscape pages as landscape.
- Converting Letter to A4 leaves small top and bottom margins — that's expected.
- Use Crop PDF first to remove excess margins before resizing.
How your file stays on your device
Resize Pages runs entirely inside your web browser. When you choose a file, your browser reads it into memory on your own device, a background Web Worker does the processing, and the result is handed straight back to you as a download. There is no upload step, no server that receives your document and no copy kept anywhere — close the tab and it is gone. That makes it safe for contracts, IDs, medical letters and anything else you would rather not send to a stranger's server. How in-browser processing works
FAQ
Resize Pages: frequently asked questions
Will my content be stretched?
No. Content is scaled uniformly to fit the new page and centered, so there may be small margins.
Are my files uploaded to a server?
No. Resizing happens entirely inside your browser using JavaScript and WebAssembly. Your files never leave your device, and nothing is stored after you close the tab.
