What is Our PDF Blurring Tool?
A powerful online utility that allows you to obscure sensitive information by applying a permanent blur effect to any part of your PDF document.
Flexible & Secure Blurring
Our PDF Blur tool provides a simple yet effective way to protect privacy. You can either draw precise boxes over text and images or choose to blur entire pages. The blur intensity is fully adjustable, giving you control over how unreadable the content becomes.
Unlike some editors that add a removable layer, our tool permanently alters the document's image, making the blurred content unrecoverable in the final file. This entire process is performed securely in your browser, guaranteeing that your sensitive documents are never uploaded to a server.

How to Blur Your PDF
Follow these simple steps to permanently obscure sensitive information in any PDF in minutes.
Upload Your PDF File
Drag and drop your PDF file into the designated area, or click the "Select PDF" button to choose it from your computer. An interactive preview of your document will appear.
💡 Tip: Your file is processed entirely in your browser and is never uploaded, ensuring complete privacy.

Apply & Download
Once you are satisfied with the settings, click the "Apply & Finalize" button. The tool will generate your new PDF with the blur effect permanently applied. You can then click "Download" to save it.
âš¡ Important: The blur effect rasterizes the page, meaning text becomes part of an image and is no longer selectable. This process is permanent.
Quick Tips for Blurring PDFs
Use Live Preview
The blur boxes on the document give you a live preview of the effect. Adjust the intensity slider to see the changes in real-time.
Find the Right Intensity
A low intensity might be enough to make text unreadable, while a high intensity is better for completely obscuring faces or images.
Use Full Page Blur for Speed
If you need to obscure an entire document quickly, choose "Blur entire page(s)" and "All pages" to process the file in one go.

Frequently Asked Questions
Get instant answers to common questions about our PDF Blurring tool.
Is it safe to upload my documents to be blurred?
Yes, it is 100% safe. Your privacy is our top priority. The entire blurring process happens locally in your browser. Your files are never uploaded to our servers, ensuring your data remains completely private and secure.
Is the blur effect permanent?
Absolutely. When you apply the blur, the tool essentially replaces the page with an image that has the blur effect "baked in". The underlying text or images are replaced and cannot be recovered from the downloaded file.
Will blurring increase my file size?
It's possible. Because blurring converts text-based pages into images, the final file size might increase, especially for documents with a lot of text. However, for image-heavy documents, the change may be minimal.
Can I undo a blur?
Before finalizing, yes. You can easily move, resize, or delete any blur box you've drawn on the preview. However, once you click "Apply & Finalize" and download the new PDF, the changes are permanent and cannot be undone.
What happens to my file after I'm done?
Since your file is never uploaded, it remains on your computer. The blurred PDF is generated in your browser, and you download a new copy. We never see, access, or store your original or blurred files.
