Question 1

Is it safe to insert a watermark online into my PDF?

Accepted Answer

Yes, usage is completely free. No registration is required, there are no hidden costs, and PDFs are created without watermarks. More information can be found here: ilovepdf.com/help/security

Question 2

Are my files saved or automatically deleted after upload?

Accepted Answer

All files you upload are protected throughout the entire process. They are used exclusively to create your desired output file (e.g., PDF file), and all data is always transmitted encrypted.

If you don't delete them manually, the system automatically and permanently deletes your files after a maximum of 2 hours. Access by third parties is therefore excluded. There is no permanent storage. More information can be found here: ilovepdf.com/help/legal

Question 3

Can I adjust the position, transparency, and size of the watermark?

Accepted Answer

Yes, at iLovePDF you can freely adjust the position, transparency, and size of your watermark. You decide where your text or image should appear on the page. Top, bottom, centered, or at any position. Additionally, you can set the opacity so the watermark either subtly stays in the background or remains clearly visible.

The size can also be scaled flexibly, so logo watermarks work just as well as large "Draft" or "Confidential" markings. All settings are shown in a preview before you finally save the PDF.

Question 4

Is the watermark applied to all pages?

Accepted Answer

By default, the watermark is applied to all pages of your PDF on iLovePDF. However, you can set whether it should really appear on every page or only on specific ranges, for example only on the first page or a selected range.

This makes the tool suitable both for simple documents and for large PDFs where only individual pages should be marked.

Question 5

Does my PDF get larger after adding the watermark?

Accepted Answer

Yes, in most cases your PDF will become slightly larger after adding a watermark. This is because the watermark (whether text or image) is embedded as additional content on each affected page.

Image watermarks especially increase the file size, as new graphic data needs to be saved. However, the increase usually remains moderate and does not affect the use or sharing of the PDF.

Question 6

Does adding a watermark work on mobile, tablet, Mac, or PC?

Accepted Answer

Yes, you can use the mobile app for free on your phone at ilovepdf.com/mobile (iOS / Android). The tool also works directly in your phone and tablet’s web browser.

Another option is to convert your documents offline , meaning not via the online service, but locally on your device. This option is available for Mac and Windows: ilovepdf.com/desktop You can also download the iLovePDF app from the Microsoft Store.

Question 7

Can I remove an existing watermark?

Accepted Answer

You can only remove an existing watermark if the PDF is not protected or technically "flat" embedded.

In many PDFs, the watermark is permanently integrated into the page structure and cannot be deleted separately. However, if the document is still editable and the watermark exists as a separate layer, you can remove it with appropriate tools.

Question 8

Can I insert my company logo as a watermark and can it be removed later?

Accepted Answer

Yes, you can easily insert your company logo as a watermark at iLovePDF. The logo is embedded as an image on each desired page and can be adjusted in size, position, and transparency.

Whether it can be removed later depends on the PDF itself: if the final document is not protected and the watermark is not "flat" rendered into the page, it can be deleted with suitable software. However, in many cases, a watermark is permanently integrated into the page structure and cannot be removed separately.
