3 reasons why PDF files cannot be edited

php editor Youzi will analyze three reasons why PDF files cannot be edited. The PDF format is popular for its stability and security, but it cannot be edited directly. This is mainly because the content of PDF files is usually stored in the form of pictures or vector graphics, and text and images are "frozen" on the page and cannot be modified directly. Secondly, the editing permissions of PDF files are restricted and may be set to read-only or password-protected. Finally, the typesetting and layout of PDF files are complex and relatively difficult to edit, requiring professional editing tools to make modifications.

Reason 1:

PDF files are scanned copies, which are equivalent to image formats. The file content cannot be directly edited. The text needs to be recognized before editing.

We can use image recognition software to recognize the text, or use a PDF editor with recognition function. After opening the PDF file through the editor, find [OCR Recognize Text] in the menu option.

If there is not a lot of content that needs to be identified, we can also use the "extract text" function that comes with WeChat screenshots to identify it.

The following picture is an example. After taking a screenshot of the image text through WeChat, select the "Extract Text" option in the screenshot toolbar;

After clicking "Extract text", the files in the picture will be automatically recognized and extracted.

Reason 2:

PDF files are opened through a browser or PDF reader. If you use these two methods to open PDF files, you can only browse the file and cannot edit it.

We need to use a PDF editor to edit PDF files. After opening the PDF file through the editor, find [Edit Text] in the menu option [Edit] list to edit the text.

You can see that under the [Edit Text] option, the document content can be changed and edited in various ways.

If you don’t have a PDF editor, or you feel that the PDF editor is not convenient for editing, we can also use a PDF conversion tool to convert the PDF file into a Word document and then edit it.
