PDF tools, image tools and SAR redaction
Everyday document jobs, photos and screenshots, or a sensitive disclosure. Choose the workspace for your task, with your files processed on your device.
For sensitive records and disclosure
Review documents, redact personal information and manage a Subject Access Request from evidence to disclosure.
For everyday PDF work
Prepare, edit and convert documents without starting a SAR case. Open the tool you need and download the result.
For photos and screenshots
Cut out a background, shrink a photo for email or strip its hidden location before you post it. The AI runs in your browser, so pictures are not uploaded.
Which workspace?
Use the SAR workspace to bring together evidence, preserve the data subject's information where appropriate and review third party information before disclosure. Detection suggestions help you find possible matches; they do not make the disclosure decision.
Use PDF tools to merge the files, put pages in order and add page numbers. Keep the originals, then check the downloaded copy for missing pages and orientation before sharing it.
Use PDF tools for a supported workbook conversion. For sensitive spreadsheet evidence, use the SAR review workflow. Neither route should be mistaken for producing a safely redacted Excel workbook.
Working with your files
Open PDF tools for an individual document job, image tools for a photo or screenshot, or the SAR workspace for evidence review and disclosure. Select files from your device inside that workspace.
Office conversions can change fonts, page breaks and complex layouts. OCR can misread scans. Redaction needs a human check, even when technical export verification passes.
Save the output before closing the tab. For a SAR case, download an encrypted case file to continue later and keep its password safely. A downloaded document is not automatically encrypted.
All three workspaces process the files you select locally rather than sending them to a processing server. This public website has separate advertising and analytics arrangements. Read the privacy notice.
A companion for Chrome
The Chrome extension supports document and screenshot redaction. Use it for a quick capture or individual document; use the SAR workspace when you need case evidence and disclosure records.
Check the store listing for the currently published version and its supported features.
Practical guidance
Choose between editing, conversion, compression and OCR, with checks for common output problems.

Read the security modelYes. RedactNinja SAR is the evidence and disclosure workspace at app.redactninja.com. RedactNinja PDF is the general document toolkit at pdf.redactninja.com. RedactNinja Image is the photo and screenshot toolkit at image.redactninja.com. Opening one does not transfer your files or case into another.
Not always. Supported Word, Excel and PowerPoint conversions have layout and content limitations. Check images, tables, fonts and pagination, and keep the original file. See the PDF tools guide before converting an important document.
No. Names, scanned text and context can be missed. Review suggestions and every output page before disclosure. Do not use a drawing or watermark as a substitute for a redaction tool.
