Launch Free Local Photo RedactorThe Danger of Uploading Passports & Utility Bills to Cloud PDF Tools
- Many free online PDF or image editing websites upload your files to remote cloud servers where they may be logged, cached in unencrypted buckets, or inspected by third-party workers.
- Landlords, utility providers, and KYC services often request proof of address or income, but only need to verify your name, not your sensitive tax numbers or bank balances.
- MaskMyBody operates under a strict zero-server airgap architecture: your sensitive document is decoded, painted, and exported entirely within your computer’s local memory.
How to Redact Photos Locally (Step-by-Step)
- Step 1: Drop Photo of ID or Document Select a photo or scan of your passport, driver license, pay stub, or utility bill. It loads into local RAM in under 5ms.
- Step 2: Select Brush Mode Activate the precision brush. Adjust the size with the slider or tap to stamp fingertip-sized privacy pads.
- Step 3: Paint Over Sensitive Data Drag your cursor or finger over Social Security numbers, bank balances, passport MRZ codes, and street addresses.
- Step 4: Download Sanitized Document Export a flattened JPEG or PNG. Blacked-out pixels are replaced with pure black (#000000) with zero underlying text data.
Frequently Asked Questions
Can someone remove the black boxes to see what was underneath?
No. When MaskMyBody exports your image, the canvas is flattened into a single image layer. The black pixels permanently replace the original pixels, making it mathematically impossible to recover what was underneath.
Why is client-side redaction safer than online tools?
Cloud tools transmit your file over the internet to a remote server. If that server is compromised, misconfigured, or keeps temporary cache files, your ID is exposed. MaskMyBody runs entirely inside your browser; no document data ever travels over the internet.
What details should I redact before sending a rental application?
Common details to redact include full Social Security or Tax ID numbers (leave only the last 4 digits if requested), bank account numbers, signature samples, and passport machine-readable zones (MRZ).
Does this remove phone and camera metadata from document scans?
Yes. All original EXIF camera metadata and location timestamps are completely removed from the exported image.
