About Resize PDF
Resize PDF changes the page size of a PDF to A4, Letter, Legal or A3. It is useful when a document made in the US (Letter) has to be printed or submitted on A4, or when pages of mixed sizes need to become one consistent size.
Each page is scaled to fit the new size without distortion and centred on it. Landscape pages stay landscape and portrait pages stay portrait, so nothing is squashed onto the wrong orientation.
How to use Resize PDF

When to use Resize PDF

- Making a document with mixed page sizes consistent before merging or printing.

Tips and common problems
- Letter and A4 have different proportions, so a small white margin appears; that is expected.
- Resizing changes page dimensions, not the file size in MB. Use Compress PDF for that.
- For printing, also set your printer to "Actual size" so it does not scale the page again.
