Generate cryptographically secure random passwords in your browser with crypto.getRandomValues. Tune length and character classes, exclude look-alike or ambiguous characters, and produce single passwords or batches ready to copy or download.

Batch-compress, convert, and resize PNG / JPEG / WebP in the browser. Drop up to 100 files, pick format and quality, and download the optimized set as a ZIP. Files never leave your device — EXIF metadata is stripped automatically.

Drop in one source image, get a ZIP with multi-size favicon.ico, Apple touch icon, Android Chrome icons, Web App Manifest, and a ready-to-paste head snippet. No third-party upload.

Generate QR codes from a URL endpoint. Custom colors, error-correction level, quiet-zone margin, and PNG/SVG/WebP/JPEG output. Bulk mode turns a list of lines into a downloadable ZIP of individually named codes.

Drop-in replacement for placehold.co: generate raster and SVG placeholders of any size, color, and pattern from a URL. Includes presets for common social and display dimensions plus a ready-to-copy responsive srcset.

Render 1200×630 Open Graph images straight from a URL. Point your og:image meta tag at the endpoint and get server-side rendering, disk caching, and five production-ready presets — no build step required.
