PDF Redaction & Privacy
How to redact a PDF for free without Adobe Acrobat?

Is it safe to use free online PDF redactors for bank statements?
Most online PDF redactors upload your files to their servers, which is risky for bank statements. Blur My Text is safer because it processes everything locally in your browser - your bank statement never leaves your device. Convert PDF pages to images, redact them in Blur My Text, then save securely.
How do you black out text in a PDF so it cannot be copied or searched?
Convert PDF pages to images (which removes text layers), then use Blur My Text's Blackout mode to permanently cover sensitive text. When you download the result as an image, the original text is destroyed and cannot be copied, searched, or recovered - it's a true redaction.
Can a redacted PDF be un-redacted by someone else?
If you convert PDF to image and use Blur My Text's Blackout mode, no - the redaction is permanent and cannot be reversed. However, some PDF redaction tools only hide text with a black overlay while keeping the original text in the file. Always convert to image format for true permanent redaction.
Security & Unblurring Concerns
Does the iPhone highlighter tool actually hide text safely?
No. iPhone's Markup highlighter is semi-transparent and can often be bypassed by adjusting image brightness, contrast, or using photo editing tools. It's not safe for hiding sensitive information. Use Blur My Text's Blackout mode instead for truly permanent and safe text hiding.
Can someone revert or unblur a blurred image?
No. When you use Blur My Text, the blur is permanently applied by destroying and replacing the original pixels. The blurred image cannot be unblurred or reversed by any tool or technique. The original information is permanently gone from the downloaded file.
If I paint over text on a screenshot, can it be reversed by changing brightness?
It depends on the tool. Semi-transparent paint or highlighter can sometimes be reversed. However, Blur My Text's Blackout mode uses 100% opaque solid black (RGB 0,0,0) that completely destroys the underlying pixels. Changing brightness, contrast, or any other setting cannot reveal what's underneath.
How to permanently blur text so it can't be reversed or hacked?
Use Blur My Text's blur or blackout feature. Both permanently modify the image pixels - the original data is destroyed and cannot be recovered through any means. For maximum security on highly sensitive data, use Blackout mode with a large brush size to ensure complete coverage.
Is it safe to upload screenshots with private info to online blur tools?
Most online blur tools upload your images to their servers, which is not safe for private information. Blur My Text is different - it's 100% client-side, meaning your images never leave your browser and are never uploaded anywhere. This makes it safe for even the most sensitive screenshots.
How to make sure blurred text is 100% unreadable?
Use Blur My Text's Blackout mode instead of Blur mode for critical information. Make multiple passes over the area to ensure complete coverage. Use a brush size larger than needed. Before sharing, zoom in and carefully inspect all blurred areas. For financial or legal documents, always prefer solid blackout over blur.
Privacy & Security
Is my data really private? Do you store my images?
Absolutely private. Your images never leave your device. All processing happens entirely in your web browser using HTML5 Canvas API.
We don't have servers to upload images to, we don't store anything, and we don't even see your images. This is true client-side processing—your data never touches our infrastructure.
Do you use cookies or tracking?
No. We don't use cookies, tracking pixels, or any analytics that monitor your usage. The only local storage we use is to save your dark mode preference (light/dark theme).
Can the blur/blackout be reversed or removed?
No, the edits are permanent. When you download your edited image, the blur or blackout is permanently applied to the pixels. The original information cannot be recovered from the edited image.
This is a destructive edit—it's not a filter that can be removed. Your original image on your device remains unchanged, but the downloaded edited version is permanent.
Is it safe to use on sensitive documents?
Yes, it's safe to use on any sensitive documents because everything happens locally in your browser. For maximum security on highly sensitive documents, we recommend using Blackout mode instead of Blur mode, and always double-check that all sensitive information is completely covered before sharing.
Features & Functionality
What's the difference between Blur and Blackout modes?
Blur mode applies a smooth blur effect that makes text unreadable while keeping some visual context. It's great for casual sharing and social media.
Blackout mode completely covers areas with solid black rectangles, providing maximum privacy. Use this for public sharing or when you need absolute certainty that information is hidden.
What image formats are supported?
We support all common image formats: PNG, JPG/JPEG, WebP, and GIF. The output is always saved as PNG for best quality. Maximum file size is 10MB.
Can I undo or reset my edits?
Yes! Click the "Reset" button to restore the original image and start over. You can also use the Delete key as a shortcut. Note: This only works before you download—once downloaded, the edits are permanent in that file.
Are there keyboard shortcuts?
Yes! Here are the available keyboard shortcuts:
- B — Switch to Blur mode
- N — Switch to Blackout mode
- Ctrl+S — Save/Download image
- Delete — Reset to original
Can I edit multiple images at once?
Currently, you can only edit one image at a time. After downloading your edited image, simply upload another one to continue. This keeps the tool simple and ensures optimal performance.
