Frequently Asked Questions

Is my file uploaded, and what is the maximum file size?

No upload is needed. This tool runs entirely inside your browser, so your file is never sent to a server. Files of up to 20MB are supported and processed locally on your own device.

How do I change the page size of a PDF?

Choose a standard size such as A4 or Letter, or enter custom dimensions, then download.

What is the difference between stretch and fit?

Stretch changes the page proportions, while fit keeps the aspect ratio and adds white space where needed.

Does resizing reduce quality?

No. Pages are placed onto a new canvas at their original size unless you ask for a stretch.

Are my files uploaded?

No. The file is processed by JavaScript inside your own browser, so it is never uploaded to a server.
