How can I resize every page of a PDF to A4?
Add your PDF (A3, US Letter or mixed page sizes) to Lunyce, keep A4 as the target size, then download the resized file. Each page is scaled in proportion and centred, without distortion, and landscape pages stay landscape. Processing is local with no upload, free, account-free and without file size limits.
How to
- Add your PDF.
- Choose the target size (A4 by default).
- Start, then download the resized PDF.
Frequently asked questions
Is the content distorted?
No: each page is enlarged or reduced keeping its proportions, then centred on the A4 page. A landscape page stays landscape.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
