Pro Tips for Crop & Resize
- Drag the corner or edge handles directly on the page preview to visually frame your content, then fine-tune with per-side sliders.
- Crop only trims the visible area — it doesn't delete content, so you can always start over from the original.
- If you're not sure of the target size, A4 is the international default and Letter is standard in the US.
- Resize after merging if you combined PDFs with different original paper sizes.
Frequently Asked Questions About Crop & Resize
Will my PDF file be uploaded to a server?
No — nothing is uploaded. This tool runs entirely in your browser via WebAssembly/JavaScript; your file never leaves your device.
Is there a file-size limit, a usage cap, or a hidden fee?
It's free and unlimited, with no watermark and no forced file-size cap — the only real limit is your own device's memory for very large files.
Do I need to create an account or sign up?
No — no account, email, or sign-up is required for any tool. Just start using it.
Can I use this on my phone (iPhone or Android)?
Yes — it works in any modern mobile browser, no app install needed.
Does cropping delete underlying content permanently?
No. Crop only trims the visible area and does not delete content, so you can always start over from the original file.
