Scale or fit pages to A4, Letter, A5 or a custom size, with margins. Text stays sharp.
Free, no uploads, no sign-up. Runs 100% in your browser.
How Change PDF Page Size works
Each page is placed on a new sheet as vector content with pdf-lib, so text and drawings are not re-rendered and stay sharp. Rotated pages are handled so they appear upright.
Input: PDF. Output: PDF.
How to use Change PDF Page Size
- Drop your PDF onto the Change PDF Page Size area, or click to choose it.

Tips
- Use Fit to keep everything visible, or Fill to cover the sheet edge to edge.

Change PDF Page Size FAQ
- Are my files uploaded?
- No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
- Is it free? Are there limits or watermarks?
- Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
- Does it work offline?
- Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
