Daylight

See what's hidden in your photos. Then fix it.

Daylight is a privacy-first image toolkit that processes everything in your browser. Drop a photo and instantly see what metadata is hiding inside — GPS coordinates, camera info, timestamps, editing software. Then strip it, compress, convert, and resize. Your photos never leave your device.

Why Daylight?

Most image tools upload your photos to their servers. Even the ones that claim they don't — how would you know?

Daylight is different:

  • Zero network requests. Open your browser's DevTools Network tab while using Daylight. You'll see nothing. That's the point.
  • No servers. We literally don't have any. Daylight is a static site that runs entirely in your browser using modern web technologies (Canvas API, WebAssembly).
  • Prove it yourself. The trust banner at the top of every page shows a live count: photos processed, network requests made (always 0), and data uploaded (always 0 bytes).

Tools

Privacy Audit (The Scary One)

Drop a photo and see everything that's hidden inside:

  • GPS location plotted on an interactive map — see exactly where the photo was taken
  • Camera info — make, model, lens, serial number
  • Timestamps — when it was taken, when it was last edited
  • Software — what app touched this photo
  • Privacy score — red/yellow/green rating of how much you're exposing

Most people don't realize that sharing a photo from their phone can reveal their exact home address.

Metadata Strip

Clean your photos before sharing:

  • One-click removal of all metadata (GPS, camera info, timestamps)
  • Selective stripping — keep orientation but remove location
  • Before/after comparison showing exactly what was removed

Compress & Convert

Shrink file sizes and convert between formats:

  • JPEG, WebP, PNG output with quality slider
  • Live file size comparison (e.g., "2.4 MB → 380 KB, 84% smaller")
  • Side-by-side quality preview

Resize

Resize images for any use case:

  • Custom dimensions with aspect ratio lock
  • Quick presets: Web (1200px), Email (800px), Social (1080px), Thumbnail (300px)
  • Live preview

Output goes to dist/ — a static site ready for deployment to GitHub Pages, Netlify, Vercel, or any static host.

The Fine Print

Unlike TinyPNG (which uploads your photos and limits you to 20/day), Canva (which charges $13/month), or countless tools that say "privacy-first" in their footer and hope you believe them — Daylight gives you the tools to verify the claim yourself. Open the Network tab. See for yourself.

Stop hoping your photos are private. Know they are.
