Developer & Privacy Utilities
Technical utilities built for developers, designers, and privacy professionals: Tesseract OCR, QR generator, EXIF scrubber, and favicon builder.
Privacy, Metadata & Inspection
Protect sensitive user data, strip geolocation, and inspect file characteristics.
Scrub GPS coordinates, camera serial numbers, and device timestamps from photos.
Inspect technical dimensions, alpha channels, aspect ratios, and dominant color palettes.
Detect typographic styles in screenshots and discover matching open-source web fonts.
Audit tracking vectors, canvas rendering hash, WebGL GPU model, and trackability score 100% locally.
Audit pages for search rankings and AI answer engine citations (SearchGPT, Perplexity) with zero server calls.
Developer Assets & Encoders
Client-side OCR text extraction, vector QR generators, and favicon bundle creation.
Extract readable text from screenshots, receipts, and scans using Tesseract.js.
Generate crisp vector QR codes for URLs, WiFi credentials, vCards, and plain text.
Build multi-resolution favicon.ico, Apple touch icons, and site.webmanifest packages.
Create pixel-perfect banners and headers for YouTube, Twitter/X, and LinkedIn.
Execute complex batch operations through a client-side Web Worker scheduler.

Frequently Asked Questions
Why should I remove EXIF metadata from photos before publishing?
Digital cameras and smartphones embed hidden EXIF tags into image files, including your exact home GPS latitude/longitude, camera model, date and time, and software versions. Removing this data prevents location tracking and protects your privacy.
How does in-browser OCR operate without sending my screenshots to an API?
ImgZero runs Tesseract.js compiled into WebAssembly. Language training dictionaries are cached locally in your browser, allowing text recognition to run offline on your device.
What resolutions are included in the generated Favicon pack?
The generator produces a standard multi-size favicon.ico (16x16, 32x32, 48x48), high-resolution apple-touch-icon.png (180x180), Android Chrome icons (192x192, 512x512), and a valid site.webmanifest file ready for deployment.
