Common Mistakes That Ruin Watermarked PDFs
These are some common mistakes that can ruin the appearance and readability of watermarked PDF files.
Using 100% opacity → Most new users make the watermark far too dark. It becomes distracting and makes the underlying text unreadable.
Applying to the wrong layer → Almost every other tool adds the watermark on top of all text. You should always put it underneath the content.
Using JPG logos for watermarks → JPG logos will have an ugly white box around them. Always use a transparent PNG for image watermarks.
Resizing the watermark after upload → Most tools stretch logos unevenly. Always resize your logo before you upload it.
Saving the original file over → Always keep an unwatermarked copy of your original PDF. Most people learn this one the hard way.
