You can edit a PDF for free using Adobe’s online tools and a free Adobe account. All you need is a computer, tablet, or smartphone connected to the internet. Simply upload your file using the Select a file button or by dragging and dropping the file into the box with the dotted line above.

The file will upload and then you’ll be asked to sign into your Adobe account. If you don’t have an account, you can easily create one – it’s free. Then you can make your edits to the PDF and download or share via email directly from the Adobe page.

You can easily add text to your PDF document using Adobe’s free online tools – whether that’s single words, sentences, or full paragraphs. Simply upload your file above and find the Add Text tool (Select tools > Edit PDF > Add text).

From here, you can add copy in your chosen font and size to match the rest of the document. You can use options under the Format menu to tweak things like paragraph spacing. When you’re done, simply save and download or share. You’ll need to login to your free Adobe account – or create a new one.

To add drawings to your PDF file, you can use the Adobe Acrobat online PDF editor tool for free. Simply use the freehand draw tool to create anything you'd like, including shapes, arrows and more. You can also change the colour to suit your preferences.

It's easy to share an edited PDF file with the Adobe Acrobat online PDF edit tool. Simply sign in, then add your comments to the PDF. Once you're done, share the file with multiple reviewers to gather feedback in one place, or share an online link to the file with others. You can also share your PDF by email.

The PDF goes back over 30 years. Adobe began work on what would become the PDF back in 1990 when co-founder Dr John Warnock launched a project called Camelot. But it wasn’t until 1993 that the PDF got the name we know so well – Portable Document Format, or PDF for short – and a proper launch, with password protection following soon after.
