How to Crop a PDF Online

With offices, businesses, schools, and everyday communication going paperless, there is an increased need for users to edit, manipulate, and share documents.

Many companies and individuals use PDF files for team collaboration projects, applications, and public documents such as company policies, user manuals, and general information.

How can you convert, merge, edit and crop these PDF documents, and what is the best PDF editor to use?

What is a PDF?

PDF, short for Portable Document Format, is a type of file with the extension .PDF after its name. These files are usually read-only documents and meant to be used as-is, such as user manuals, scanned pages, business proposals, contracts and documents that the sender doesn’t want to be edited.

Adobe originally created the PDF format so that users can share documents across different platforms and computers without the document changing formats, fonts, and layouts. This is a common problem with other file types as not all computers can open every extension and even different versions can look different. If you ever opened a document written in a font that you don’t have on your computer, you can relate to this issue.

A PDF file avoids these problems as it will look the same on every device and platform. It is universally consistent.

This raises the question of how to edit a PDF on a Mac and Windows and how to edit a PDF document online if they are not meant to be edited. To edit a PDF file, you will need to use a PDF editor. PDF editors are applications that enable you to edit the PDF – add and change text, rotate pages, and crop pages.

What Does it Mean to Crop PDF Files?

Cropping a file is when you cut out parts of the document. Select the area of the document that you want to be visible, and the area that is outside of the selection will be hidden from view.

Visually, cropping a PDF is similar to cutting out a part of a document. However, cropping does not change the contents or layout of the document, nor its file size. It merely hides the parts of the document that are trimmed out.

After you crop PDF documents, you may still be able to view the complete document, including the areas that were cropped out, in some PDF viewer applications.

Why Would You Need to Crop a PDF?

You may need to crop a PDF for similar reasons you would need to cut a paper document:

• There is only one section of the document that you want to share, paste, or print.
• There is extra unnecessary space or margins around the image or text.
• The document is too large for your needs. Note that cropping the file will reduce the amount of space you see on the screen, not the amount of memory of the file, as the cropped-out area is still in the document – just hidden.

As more people work remotely, they rely on the Internet and online applications to manage their documents.

7. Using your mouse or touchpad, drag the cropping icon around the area of the document you want to preserve. Then click on the checkmark to confirm.

How to Crop a PDF on Mac

The Sizle application is compatible with a Mac and is an easy, quick, and convenient way to crop a PDF document online.

You can also crop the file using the Mac’s Preview application.

How to Crop a PDF in Preview

To crop a PDF in Preview:

1. Open the PDF file, either by selecting it from the finder or from within the Preview application. To open it in Preview, select File -> Open and find the document.
2. From the Menu bar, select Tools -> Rectangular Selection.
3. Drag your mouse or touchpad to drag a rectangle over the area you wish to keep in the document. A dotted border will appear around the selected area. The parts of the document that are outside of the rectangle will be cut out.
4. From the Menu bar, select Tools -> Crop.
5. The PDF will now display only the parts of the document that were within the rectangular selection. You can save, share, or print it as needed.

The Preview application may issue a warning that the parts of the document cut out are not permanently removed, but just hidden from view, and it may be possible to view them in other programs. Cropping a PDF does not cut the file but hides the unselected portion from view.

To completely cut out a section of a PDF, you can take a screenshot of the area you want and then paste the screenshot image into a new document. This will be an image file, though, not a PDF. You can paste the image into a document and save it as a PDF, but you won’t be able to edit that image in a PDF editor subsequently.

To take a cropped screenshot on a Mac, you can use the Screenshot utility.

1. Open the PDF on the Mac.
2. Go to the computer menu options. You may need to click off of the PDF or minimize it to get the main options.
3. From the main toolbar, select Go and then Utilities.
4. Choose the Screenshot utility from the list.
5. The Screenshot utility menu window will open.
6. Before you take the screenshot, click on the Options icon and select where to save the screenshot. Choose clipboard if you will then paste the cropped portion of the
7. PDF into a new document or email. To automatically save it, choose the destination.
8. From the list of screenshot options, choose the Capture Selected Portion to draw an area to crop.
9. Use your mouse to draw around the area that you want to crop.
10. The screenshot will be saved as per the options you previously selected.
11. Since the cropped area is a screenshot, the hidden portion of the PDF won’t be able to be seen in this new image.

How to Crop a PDF in Windows

Many software applications and programs can crop a PDF on a Windows computer, including the free online PDF editor, Sizle.

You can also crop the document with Windows’ own snipping tool.

1. Find the PDF file and click on it to open. It will open in your computer’s default PDF viewer application. You can also open it in your browser.
2. Open the Snipping utility. To find the tool on your computer, press the Windows key on your keyboard to open the search bar. In the search, type “Snipping” to find the application. Click on the Snipping tool to open it.
3. On the menu bar, choose an option from the Mode dropdown list. Use the rectangular snip to crop a rectangular-shaped area of the document, such as a block of text. Use the free form snip option to select your own area, such as to crop out a corner.
4. With your mouse or keypad, select the area of the PDF you want to keep. The selected area will display in the Snipping window.
5. You can then copy, share, save, or print the cropped PDF or paste it into a new PDF document. Keep in mind that this will be an image, not a PDF.

Editing a PDF File

Some PDF documents are meant to be edited and are created with fields that you can fill in, such as an application or survey form. If the PDF has fillable fields, you can enter your text and then save the PDF with your inputted information.

What about editing a PDF without fillable fields? Can you change the text on a PDF document? There are many reasons that you might need to edit PDF documents:

• Insert and Remove Pages – If you have a PDF document of multiple pages, you may need to add another page to the document or remove some pages. Or to extract a page from the multi-page file and save it as its own PDF.
• Rotate Pages – If you receive scanned files, the pages may come in upside down. In a multi-page set of documents, you may have some pages facing one way and some other in the opposite direction, making it very difficult to read on the screen.
• Highlight Text or Add Notes – You can add text fields, notes, and highlights to the PDF document. This is great for collaboration projects or your own work and notes.
• Add Forms – Create fillable fields on the PDF.
• Crop PDF Pages – Select specific areas of the PDF to be visible.
• Edit the Text – Add new text fields over the existing text to type in the changes. Use the same font so the changes will be seamless.

The situations are pretty common and come up very often when you’re working with PDFs and sharing files with other parties. You can make these changes using a PDF editing program such as Sizle.

How to Edit a PDF Document on Mac

You can edit a PDF document on a Mac using a number of PDF editing tools, but you can do it free with Sizle or with the Mac’s Preview app.

1. Open the file in Preview. If it’s your default PDF viewer, the PDF will open in the application when you double-click on it.
2. Use the editing tools on the menu bar to make the changes to the PDF document.
3. To change the text, create a new text field. Drag the text box over the existing text and type in the new text. Use the same font and text size as the original text.
