How to resize PDF pages in bulk
- Drop in your PDFs, or press Choose a folder.
- Choose the new paper size and how the content should fit.
- Press Resize PDFs, then download each PDF or everything as one ZIP that keeps your folder layout.
🔒 Your PDFs are resized by your own browser and are never uploaded to our server.
Good to know
- A4 is a little narrower and taller than Letter, so scaling between them shrinks content by about 6% and leaves a thin band of white space.
- Text stays sharp and selectable. Pages are scaled, not turned into pictures.
- Form fields, links and comments are not carried over to the resized pages. Flatten forms first with the PDF Flattener if you need to keep the answers.
