How to crop PDF
- Choose or drop the PDF.
- Drag on the page to draw the area to keep, and adjust it with the handles.
- Choose which pages to crop, then select “Crop PDF”.
Private by design
Most online PDF tools upload your document to their servers. This one doesn’t: Crop PDF runs entirely in your browser, so contracts, forms, IDs and photos never leave your device. It’s free and adds no watermark, and you don’t need an account.
Questions
Is the cropped part deleted?
Cropping sets the visible area of each page, which is what every viewer and printer shows. The hidden content is still in the file, so don't rely on cropping to remove private information.
Can I crop pages differently?
Yes. Choose “Page by page”, then draw a different box on each page you want to crop.
Can it trim white margins automatically?
Yes. “Fit to content” finds the printed area of the page and puts the box around it, ready to adjust or apply to every page.
Will cropping lower the quality?
No. Nothing is re-drawn; text and images stay exactly as sharp as before.
Are my files uploaded?
No. Every tool runs in your web browser, so your files are read, changed and saved on your own device and never sent to LabAnvil or anyone else. Once the page has loaded, the tools even work offline.
Is it free? Do I need an account?
Free, with no watermark, no daily limit and no account.
