- Data minimisation: Only collects data that's strictly necessary.
- Purpose limitation: Uses data only for the stated purpose.
- Consent: Clear opt-in for any data processing.
- Right to deletion: Users can request data removal.
- Transparency: Clear privacy policy explaining data handling.

Technical Verification & Standards Compliance for Digital Submissions
When uploading photographs, signatures, or official records to government portals, visa processing systems, or recruitment boards, strict automated validation scripts evaluate both visual clarity and physical file parameters. Minor errors—such as non-standard aspect ratios, improper pixel dimensions, high compression artifacts, or unstripped EXIF headers—frequently trigger instant system rejections.
Image Dimension & Aspect Ratio Math
Official forms specify exact physical measurements (e.g., 3.5cm × 4.5cm) or pixel boundaries (e.g., 350×450px). Converting physical units into digital resolution requires applying exact DPI scales: Pixels = (Millimeters / 25.4) × DPI.
Local WebBrowser Compression Engine
PhotoResizer.in uses client-side HTML5 Canvas and WebAssembly algorithms to compress image streams down to specific KB limits (10KB, 20KB, 50KB, 100KB, 200KB) entirely inside your web browser. Visual data never leaves your device.
