Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Now 60+ tools: a full color suite with Contrast Grid, column grid math, a device database, Figma-to-code translators and QR codes. One purchase, no subscription. PixelKit is the all-in-one toolbox for designers and developers — a precise unit converter plus a full suite of design, print, and dev calculators in one fast, offline app. No account, no ads, no subscription. It started as the ONLY true pixel converter on the App Store — the only app that correctly converts inches to pixels at 1in = 96px. That precision is still the heart of PixelKit, now surrounded by the tools you reach for every day. THE CONVERTER: • Convert across 11 units: pixels, inches, cm, mm, picas, points, em, rem, viewport (vw), DPI, PPI • Real-time, pixel-perfect accuracy with a custom keypad • Conversion history, custom presets, batch convert, compare up to 3, CSV export • Copy all formats at once DESIGN & LAYOUT TOOLS: • Screen Calculator — PPI, retina class, megapixels, dot pitch, aspect ratio from width/height/diagonal • Aspect Ratio Calculator — lock dimensions, common and custom ratios, simplified GCD • Typography Scale Generator — modular type scale with per-step values • Coordinate tools — distance, area, golden ratio, grid alignment, center point PRO TOOLS (one-time unlock): • Print Production — bleed, paper GSM, binding, fold, stack thickness, die-cut • Image Assets — file-size estimation, print DPI, retina @1x/2x/3x, compression, color space (sRGB / Adobe RGB / CMYK) • Animation — frame rate, easing and bezier with code output, motion blur, duration, keyframes • Validation — WCAG AA/AAA contrast, pixel-perfect, platform compliance, print quality • Cross-platform — breakpoints, touch targets, viewport units, responsive typography EXPORT-READY CODE: • Most tools output ready-to-paste CSS and SwiftUI — easing to cubic-bezier(), breakpoints to @media queries, type scales, aspect ratios, and more BUILT TO KEEP: • Unified Recent — every calculation across every tool saved in one list, with favorites • Copy on every result, one tap • System, Light, and Dark mode • Fully offline — no account, no network, no ads ONE-TIME UNLOCK: • $6.99 once unlocks every Pro tool — and all future Pro tools, forever.
