Is Crop & Resize private?

Everything runs locally in your browser. Your files are never uploaded to StackPDF servers.

Do I need an account to use Crop & Resize?

No. StackPDF is free to use without signing up or creating an account.

Does Crop & Resize work offline?

After the page and libraries load, processing happens on your device. A connection is only needed to load the app the first time.

Can I resize a PDF to A4 or Letter?

Yes. Pick a standard page size (A4, Letter, Legal, A5) and a fit or fill strategy so content scales cleanly for printing or email.

Is cropping permanent?

The downloaded file keeps the new crop or page size. Your original stays on disk unless you overwrite it. Always download a new copy if you need both versions.

Are there size limits on Crop & Resize?

No artificial upload or page limits. Process large scanned PDFs free — only your browser memory sets a practical ceiling.

Can I crop white margins from scans?

Yes. Uniform margin crop is ideal for scanner borders and printer edges before you share or archive the file.

Can I crop the photo itself, not the PDF page?

This tool crops PDF page boxes. To crop a photo before it becomes a PDF, use [StackImage Crop](https://stackimage.stacktools.studio/crop-image).
