⚡ Quick answer

Cropping a PDF means keeping only the part of each page that you want. It is useful for removing wide margins, black scan edges, headers and footers, or for cutting a single table or picture out of a page.

Open Crop PDF, follow the steps below, and you are done in a minute or two. No sign-in is needed.

📋 How to use Crop PDF – step by step

Upload your PDF by clicking or dragging it into the upload area
Drag the red box over the part you want to keep, or click "Auto-trim white margins"
Use the shape list if you need A4, Letter, square or another fixed shape
Type exact margins in millimetres if you need them precise
Choose all pages, odd pages, even pages or your own pages
Optionally make the pages bigger or smaller, or choose a smaller file size
Click "Crop & Download PDF". The file downloads automatically

💡 Why use this tool?

Scanned pages often have thick borders, and downloaded forms often have a lot of empty space. Printing them wastes paper and reading them on a phone is harder. Cropping gives you clean pages that fit the screen or the paper better.

Unlike many online tools, your PDF stays on your own device. Nothing is sent to a server, and there is no sign-up.

❓ Frequently asked questions

Is my document uploaded to a server?

No. Your PDF is processed inside your browser and never leaves your device.

Will cropping make my PDF file smaller?

A normal crop only hides the outside area, so the file size stays about the same. To make the file smaller, choose "Remove the cropped area (flatten to images)" and a smaller quality, or use the Compress PDF tool.

Is the cropped part really deleted?

With the normal crop, the hidden part is still inside the file, and some programs can show it again. If the outside area is private, choose "Remove the cropped area", which keeps only what you chose.

Can I make the pages bigger?

Yes. In Step 3 choose a percent such as 150% or 200%. You can also choose a smaller percent to make the pages smaller. Text and drawings stay sharp with the normal method.

What does "Auto-trim white margins" do?

It looks at your pages and finds the area that has content, then puts the crop box around it. It works best on clean documents. On very noisy scans, please adjust the box by hand.

Can I crop different pages differently?

Yes. Choose "Different crop for each page", go to each page and set its box. Or click "Auto-trim each page separately".

Why does the flattened PDF have no selectable text?

The "Remove the cropped area" method turns each page into a picture. Use the normal crop if you need to select or search the text.

Can I crop a password protected PDF?

No. Remove the password first, then crop it. You can protect it again afterwards.

Is it free?

Yes, this tool is completely free to use.
