Follow these simple steps to protect your privacy when sharing sensitive documents
Click the upload area or drag and drop your image (JPG, PNG, GIF, WebP) or PDF file. All processing happens locally in your browser.
Select a custom color if needed, then choose your effect type: Mosaic (Pixelate), Gaussian Blur, or Black Out. Adjust intensity as desired.
Click "Select Area to Redact" button, then click and drag on the image to select the area you want to mask. Release to apply the effect automatically.
You can select multiple areas and apply different effects. Each selection is processed immediately. Use "Reset to Original" to start over.
For multi-page PDFs, use the Previous/Next buttons to navigate between pages. Edit each page independently before exporting.
Click "Download Redacted File" to save your edited document. Images keep original format, PDFs export as multi-page PDF with same filename.
Your files never leave your device. All redaction happens directly in your browser for maximum privacy and security.
You have complete control over which areas to redact. No automatic detection - you decide exactly what gets masked.
Choose from Mosaic (pixelation), Gaussian Blur, or solid color blackout. Customize colors and intensity for perfect results.
Edit multiple pages in a single PDF file. Navigate between pages, apply different effects, and export as complete multi-page PDF.
Exported files keep their original names, including all characters (Chinese, Japanese, Korean, etc.). No random renaming.
Once loaded, the tool works completely offline. No internet connection required after initial page load.
Image redaction is the process of permanently removing or obscuring sensitive information from photos and documents. Whether you're sharing a screenshot online, submitting documents for verification, or posting photos on social media, redaction helps protect your privacy by hiding personal data like faces, ID numbers, addresses, and financial information. Our free online tool makes this process simple and secure.
Unlike most online photo editors, our tool processes everything 100% locally in your browser. This means your images and PDFs are never uploaded to any server. All editing happens on your own device using JavaScript, ensuring complete confidentiality. This is crucial when handling sensitive documents like passport copies, bank statements, medical records, or confidential business documents.
Yes! Our free PDF redaction tool supports multi-page documents. You can navigate through pages, edit each page individually, and export the entire document as a single PDF file. Each page maintains its quality, and the exported PDF preserves all your redactions. This is perfect for editing contracts, legal documents, reports, or any multi-page PDF that needs sensitive information removed.
To blur faces effectively: (1) Upload your photo to our tool, (2) Select the area covering the face by clicking and dragging, (3) Choose a solid color or blur effect, (4) Adjust the intensity if needed for complete coverage, (5) Export the edited image. For best results, make sure the selection completely covers facial features. You can use black or white boxes for maximum obscurity, or choose a skin-tone color for a more natural look.
Absolutely! Our tool is completely free with no hidden costs. Unlike expensive software like Adobe Acrobat Pro or subscription-based services, we offer professional-grade redaction features at no cost. There are no watermarks, no usage limits, and no registration required. We believe privacy protection should be accessible to everyone.
We support all major image formats including JPG/JPEG, PNG, GIF, and WebP. For PDF files, you can import and export multi-page documents. The tool preserves the original file format when exporting - if you upload a JPG, you can download as JPG; if you upload a PDF, you get a PDF back. This ensures compatibility with your workflow.
For maximum security when hiding sensitive numbers: (1) Upload your document image, (2) Carefully select the area containing the ID number, SSN, or credit card digits, (3) Use a solid black or white box for complete coverage, (4) Make sure the selection extends slightly beyond the text edges, (5) Preview to ensure nothing is visible, (6) Export securely. Always double-check that all sensitive data is fully obscured before sharing.
Yes! Our responsive design works perfectly on smartphones and tablets running iOS or Android. You can upload photos directly from your camera roll, take new photos, or select PDF files. The touch-friendly interface makes it easy to select areas for redaction on smaller screens. Everything runs in your mobile browser - no app installation needed.
