This article provides a guide on how to crop and merge sections from one or more PDF files into a single document. You can perform this task on a Windows computer by using a combination of Snipping Tool and Microsoft Word, or by using Preview on Mac. If you're unable to use Microsoft Word and/or Preview, you can use a free online tool called PDF Resizer to split and crop PDFs.
Steps
Use PDF Resizer

Open the PDF Resizer page by visiting https://pdfresizer.com/ in your browser.

Nhấp vào thẻ Split PDF (Tách PDF) ở phía trên góc trái trang.
- Nếu tập tin PDF của bạn chỉ có một trang, bạn chuyển sang bước "Nhấp vào thẻ Crop PDF (Cắt PDF)".

Nhấp vào nút Choose Files (Chọn tập tin) màu xám ở giữa trang để mở một cửa sổ mới.

Chọn PDF của bạn. Nhấp vào tập tin PDF mà bạn muốn sử dụng. Trước tiên, có lẽ bạn cần nhấp vào thư mục lưu tập tin (chẳng hạn như Desktop) ở bên trái cửa sổ.

Nhấp vào Open (Mở) ở bên dưới góc phải cửa sổ. Thao tác này sẽ thêm tập tin PDF của bạn vào trang PDF Resizer.

Nhấp vào nút Upload files! (Đăng tải tập tin!) màu tím ở gần cuối trang.

Tick the "one page per file" checkbox (one page as a separate file) below the PDF window.

Split the PDF. Click on the Looks good, do the magic! button, then wait for the PDF file to be split into individual pages.
- This process may take a few minutes if the internet connection is slow or if the PDF file is large.

Download the PDF. Click the circular Download button on the right side of the page to download each page of the PDF to your computer.

Unzip the PDF files to make sure you can cut and merge documents. The procedure is as follows:
- On Windows - Double-click the ZIP folder, select Extract, click Extract all, and choose Extract when prompted to unzip the folder.
- On Mac - Double-click the ZIP folder to unzip it.

Reopen the PDF Resizer page. If you've closed the PDF Resizer page, you need to open it again at this step.

Click the Crop PDF button at the top of the PDF Resizer page.

Click the Choose Files button.

Select a PDF page. Click on one of the pages you just split.
- You can only crop one page at a time. If you upload multiple pages, all of them will have the same crop settings.

Click the Open button at the bottom right corner of the window.

Click the Upload files! button.

Select the area to crop. Click and drag your mouse over the section of the PDF document that you want to save.

Click on the Crop it! button near the bottom of the page.

Download the page. Click the Download button below the cropped PDF on the right side of the page to save the file to your computer.
- Now, you can upload another PDF page and continue cropping if you need to cut more pages.

Click on the Merge PDF tab at the far left of the toolbar at the top of the page.

Click on the Choose Files button.

Select all PDF pages. Click and drag your mouse across all the pages you want to merge, or hold down the Ctrl key while clicking on each file you wish to upload.
- You can select multiple files up to 100MB or 50 pages, depending on which limit is reached first.

Click on Open at the bottom right corner of the window.

Click on Upload files! to start uploading.

Review the order of the PDF pages. If the pages are in the correct order, proceed to the next step. Otherwise, click and drag the pages up or down to rearrange them.

Click on Looks good, do the magic! near the bottom of the page. This action will merge the individual PDF pages into a single document.

Scroll the slider down and download the PDF. Click on the Download button beneath the combined PDF file on the right side of the page to save the PDF to your computer.
Using Word on Windows
Open the PDF document using a PDF reader program like Adobe Reader.
- If you don't have a reader installed, you can download Adobe Reader for free from the Adobe Reader page.
Scroll to the page you want to cut. If the PDF has multiple pages and you wish to crop a specific one, make sure to open that page first before continuing.

Type snipping tool to search for the Snipping Tool on your computer.
Click on the Snipping Tool at the top of the Start menu to open a small window above the PDF file.
Enable the "Rectangular Snip" option. Click on Mode at the top of the Snipping Tool window, then select Rectangular Snip from the options list. The cursor will change to a cross icon.
Select the area to snip. Click and drag the cross icon over the part of the PDF document you want to cut. Release the mouse button, and the selected portion will be cropped.
Release the mouse button to crop the PDF according to the selected area.
Click the "Save" (diskette icon) button at the top of the Snipping Tool window to open the File Explorer window.
Click on the "Desktop" folder on the left side of the File Explorer window. This will set the Desktop as the location to save your cropped PDF, making it easier for you to find later.
Click on the Save button at the bottom right of the window to save your file in the selected folder as "Capture".
- Now, you can go back and snip other pages or PDF documents you want to crop.
Launch Microsoft Word with the white "W" icon on a blue background.

Click the Insert tab, then click Picture. You'll find Insert at the top of the Word window and Picture in the "Illustrations" section of the toolbar.
Select the image you cropped from the PDF. Click on the Desktop tab on the left side of the window, then click on the "Capture" image and choose Insert.
- If you have cropped multiple images, hold the Ctrl key while clicking on each image you want to add. Remember to select the images in the order you want them to appear.
