About Privacy & Security
Posting a single photo online has revealed home addresses; cropped meeting screenshots have leaked colleagues' data. Digital files carry information beyond the visible pixels.
Photos from iPhones and Galaxy phones embed GPS coordinates, capture time, camera model, and exposure settings as EXIF metadata. Most major social platforms strip EXIF on upload, but email, blogs, and cloud shares preserve it. Privacy tools here clean that invisible layer or hide visible regions that shouldn't be public.
In Korea, ID number leaks are a serious risk — sharing an ID card or contract scan typically requires masking the back half of the resident registration number. All processing happens in your browser, so you don't trade one privacy risk (leaving info visible) for another (uploading sensitive files to a stranger's server).

FAQ
Is removing EXIF enough?
Not always. EXIF is invisible data; but visible cues in the photo (street signs, license plates) can also reveal location. Use Image Redact for visible elements.
Can I undo a mosaic / blur?
No — pixel-averaging is irreversible. Always keep an unedited original separately.
Where should I place a watermark?
Large, semi-transparent, diagonal across the center is hardest to crop out. Small corner marks are easily removed.
Is the Korean RRN decoder safe?
Yes. The number stays in your browser, no network calls, no localStorage. Verify in DevTools → Network.
Can removed EXIF be recovered?
Not from the new file — it carries no EXIF. The original you keep still has it, so share the cleaned version.
