If the pages in a PDF have margins that are too large, you can remove the extra space from each side separately. Konvertus lets you adjust four margins: left, right, top, and bottom. This means you can change only the edges you need while leaving the others untouched.
To crop a PDF online, simply enter the margin sizes in points (pt). Positive values reduce the margins, negative values increase them, and a value of 0 leaves the corresponding margin unchanged.
The entire process takes place directly in your browser. The file is not uploaded to the server, and once processing is complete, the finished PDF is downloaded automatically to your device.
How can you reduce PDF margins?
If there is too much empty space around the content of a page, you can remove it from any side separately. Use the “Left margin”, “Right margin”, “Top margin”, and “Bottom margin” fields to enter the required values.
To reduce PDF margins, enter a positive value for the margin you want to crop. For example, if there is extra space at the top, enter the required value for the top margin and leave the other fields set to 0.
You can also change several margins at the same time. The values do not have to be identical: you can remove more space from the left, less from the right, and leave the top or bottom margin unchanged. This allows you to crop the margins of a PDF according to the position of the content on the page.
All sizes are specified in points (pt). Once the values are set, click “Crop PDF”, and the processed file will be downloaded automatically to your device.
Can you increase PDF margins?
The tool is not limited to reducing margins. If you need to add extra space around the content, you can also increase PDF margins on one or more sides.
A negative value is used to increase a margin. For example, a negative value in the “Left margin” field increases the space on the left, while the other margins remain unchanged if their values are set to 0.
The left, right, top, and bottom margins can be adjusted independently. This means you can reduce one margin while increasing another. This is useful when the original page margins have different sizes and only certain edges need to be changed.
With the same tool, you can remove unnecessary areas or increase the margins in a PDF without changing the settings for the other edges.
How can you crop pages in a PDF on multiple sides?
If there are unwanted margins around the entire page, you can enter values for all four sides. Simply specify the required margins on the left, right, top, and bottom.
To crop pages in a PDF, you do not have to use the same value in every field. Each margin is adjusted separately, so the page boundaries can be changed according to the original position of text, images, or other content.
If you only need to crop part of a PDF along one or two edges, leave the other values set to 0. For example, you can reduce the top and bottom margins without changing the width of the page.
This gives you more precise control than applying the same crop to all four sides. Before processing, you decide which margins should be reduced, which should be increased, and which should remain unchanged.
When might you need to crop a PDF file?
You may need to crop a PDF file when its pages contain large areas of empty space around the content. The amount of empty space can be different on the left, right, top, and bottom.
Instead of applying the same crop to every edge, you can specify a different value for each margin. If the extra space appears only on the right, only the right margin needs to be changed. If the top and bottom margins are too large, you can adjust just those two values.
The tool also lets you change the page boundaries in the opposite direction. If the margins are too small, you can increase them using negative values.
There is no need to open the PDF in a separate program. To crop a PDF document, simply add the file to the tool, set the four margin values, and start processing.
Why crop a PDF online for free?
To crop a PDF online for free, you do not need to install a program or create an account. The tool works directly on the page: add your PDF, enter the required values, and start processing.
The file is processed directly in your browser without being uploaded to the server. The document content is not sent to an external server to change the margins. Once processing is complete, the finished PDF is downloaded automatically to your device.
Separate settings for each margin mean you do not have to change every edge in the same way. You can reduce the margins in a PDF only where there is extra space or increase a specific margin using a negative value.
If one of the margins already has the right size, simply leave its value set to 0. This way, changes are applied only to the edges that actually need to be adjusted.
