How to Add Watermark to PDF Online. Watermarkly vs Adobe Acrobat

Adobe Acrobat is by far the most well-known software for editing PDFs. It offers a full range of tools for creating PDF files from a variety of formats, editing them, and storing them in different variations.

Using the app, you can merge the documents into one and rotate, resize, crop, or split them. For users who manage PDFs frequently and often need to adjust the content, Adobe Acrobat may indeed be one of the logical solutions, along with other alternative editors.

However, if you don’t need to edit the PDF, you only want to add a watermark in PDF, and you’ve never used Adobe Acrobat before, the choice of software is not so obvious.

It is easy to become overwhelmed with Acrobat’s toolkit. You might need to read an instruction manual or watch a YouTube tutorial before you even start using the editor. Moreover, payment for a Creative Cloud subscription will be required.

All these obstacles can be avoided by choosing a simpler, cheaper, and more user-friendly online application to watermark PDF files, such as Watermarkly. You will master it within minutes, even if you don’t have any editing skills and are not familiar with any other PDF editor.

Let's take a step-by-step look at the differences between these two applications and which one is more convenient for the inexperienced user.

Design a watermark for a PDF

Watermarkly has almost the same set of options for creating a custom watermark for PDF as Adobe Acrobat. Both the text and logo can be changed however you want. You can pick a different color or font, make it smaller or bigger, adjust the position, rotate, or change the opacity.

If you add a multiline text, you can adjust its alignment in both Adobe Acrobat and Watermarkly. Adobe allows you to underline the text. However, Watermarkly allows you to add a copyright symbol or number to your textual watermark.

The size correction method is different in each PDF watermark app. In Adobe Acrobat, you need to enter a number in the Size option for text, or a percentage in the Absolute Scale option for an image watermark.

Watermarkly allows you to change the size by moving the slider in the Settings box or by dragging the corner of the watermark. This way, you will be able to get the desired result faster.

The same goes for editing the position of the text or image. Adobe Acrobat asks you to select a number and adjust the vertical and horizontal position of the watermark by inches, percent, centimetres, millimetres, picas, or points. In Watermarkly’s free PDF watermarker, you just move it to the place you need.
