Add color overlays to your PDF documents
Click the 'Select PDF' button or drag and drop your PDF file into the upload area to start.
Select a color using the color picker. Adjust the opacity and choose a blend mode to create the perfect effect.
After applying the settings, click the 'Download' button to save your new PDF with the color overlay applied.
A PDF color overlay isn't just about changing the look of your document; it's a powerful tool for improving readability, accessibility, and visual presentation. By adding a semi-transparent color layer on top of your PDF, you can enhance contrast, reduce glare, and create a more comfortable reading experience. This is a game-changer for digital textbooks, long reports, and documents viewed on bright screens. It's a quick, non-destructive way to transform any PDF's look and feel without altering the original content.
Color overlays, often called "digital reading filters," have a wide range of applications:
Our tool goes beyond just adding a solid color. It uses blend modes, a feature traditionally found in design software like Adobe Photoshop, to control how the overlay color interacts with the colors underneath. This allows for truly unique effects that cannot be achieved with a standard watermark.
The Overlay PDF tool can be used with other PDFNano features for even greater control over your documents. After applying your perfect color filter, you might want to compress the file to reduce its size for email, which you can do with our PDF compressor. Or, if you need to add notes, highlights, or annotations on top of your new color background, our PDF editor is the perfect next step.
Changing your monitor's settings affects everything you see, while a PDF color overlay is applied directly to the document itself. This means the color filter stays with the file, so anyone you share it with will see the exact same effect. It's a permanent and portable solution, not a temporary display change.
No, the overlay is permanently merged into the PDF file. Once you download the new file, the original document is unchanged, but the downloaded version has the color layer integrated. If you need a copy without the overlay, simply use your original PDF file again with the tool.
The file size increase is minimal and typically negligible. Our tool adds a simple, single-color layer to the PDF, which is a very small amount of data compared to the full document content.
Our tool works with most standard PDF files, including text-based PDFs, PDFs with images, and even scanned documents. The overlay will be applied over all content on the selected pages, regardless of whether it's text or an image.
