Frequently Asked Questions

What page sizes can I resize to?

You can resize every page to standard A4 or Letter dimensions. Custom or other paper sizes aren't currently supported.

Will my content be stretched to fit the new page size?

No. Each page is scaled proportionally, keeping its original aspect ratio, and centered on the new page.

What happens if my PDF has pages of different sizes?

Each page is resized individually to fit the target size you choose, so mixed-size documents come out consistent.

Can I resize multiple PDFs at once?

Yes. Upload several files and each one is resized and returned together in a single zip download.

Will resizing crop or cut off any content?

No. The whole page is scaled down or up to fit, so nothing is cropped, only resized.

Does resizing change the quality of images or text?

Text and vector content stay sharp at any size. Embedded raster images are scaled along with the page.

Is it safe to upload confidential documents?

Yes. All uploads happen over an encrypted connection, and both the source file and the resized PDF are automatically deleted from our servers after processing.

Is resizing a PDF really free?

Yes. There is no cost, no subscription, and no account required.
