How to Write on a PDF

by Hung Nguyen

Need to add text onto a PDF? Check out how you can do so with the free Smallpdf editing tool, as well as other popular methods to write on PDFs.

PDF files are great for sharing, as they cannot be edited. However, there may be times when you need to annotate your PDF files, or to edit and delete existing content.

Though it may seem impossible with a free PDF reader, it's a relatively easy task. Here are a few ways that you can write on a PDF file, depending on your needs.

How to write on a PDF - by converting it back to its original format


PDF files are always exported from another format, such as Word, PPT, Excel, to be shared or stored easily. As such, you can always convert these files back their original form so that you can write/edit freely in their native formats. Smallpdf has an all-in-one converter for you to do this.

  • Access the PDF Converter.

  • Upload your file and select the output file.

  • Let our software do the work. Remember to download your file!

Smallpdf operates online, via any operating system and internet browser, for your convenience. If you wish to write on your PDF files offline, we are also working on adding this function to our free offline PDF reader, which will be available in the coming months. Watch this space!😇
