How to Edit PDF image Effectively?

Images bring documents to life. A document without images is often considered boring and hard to understand. After all, our minds are wired to understand visuals better than blobs of text. Most documents today are in PDF format because such documents can be viewed on any device and are difficult to edit. However, in many situations, you are required to edit images in PDF documents. With UPDF, you can edit PDF images as your need.

Part 1. Situations that You Should Edit Image in PDF

Since most PDF documents today contain images, it is likely that you may have to edit images in PDF. Below are a few situations that require you to edit images in PDF documents:

  1. Flowcharts and diagrams are very common in PDF documents. However, in a fast-changing world, these diagrams may require some minor changes as well due to the change in a specific flow. In this case, you will need to replace an image in the PDF.
  2. Making errors is inevitable. It is possible that an image in a PDF document is erroneously positioned. You may be required to rotate or reposition the image in such scenarios.
  3. Some PDF editors do not understand visual nuances very well. In such scenarios, they simply paste a picture into the PDF document without cropping out unnecessary elements of the image. In such situations, you will be required to crop the image and reflect only the necessary elements in the picture.
  4. As a PDF document goes through many reviews in an organization, it is possible that reviewers wish to eliminate an image from the PDF document or add a new image to the PDF document. Sometimes, it is required to copy an image from the PDF document for reusing it in another document. Therefore, basic clipboard actions on images in PDF documents are imperative.
  5. Some contents in the PDF image are wrong, you may need to update them.
