Pictiúr

Optimize images 100% locally — convert, resize and compress in one pass, right in your browser.

• 🔒 No upload: processing runs locally in your browser (WebAssembly)
• ⚡ PWA: installable, works offline
• 🧩 Formats: JPEG (mozjpeg), PNG (oxipng), WebP, AVIF, JPEG XL; HEIC/HEIF (iPhone) input via WebAssembly

Development

pnpm install
pnpm dev

Deployment

Pictiúr is a fully static app (adapter-static) — any static host works.

Docker (self-hosted)

Simplest way — official Docker image:

docker run -d --name pictiur -p 3002:80 ghcr.io/etheonor/pictiur:latest

With password protection:

docker run -d --name pictiur -p 3002:80 \
  -e USERNAME=admin -e PASSWORD=your-password \
  ghcr.io/etheonor/pictiur:latest

Or with docker-compose — see docker-compose.yml (builds locally from the Dockerfile by default).

Third-party

• @discourse/heic (Apache-2.0), which embeds libheif and libde265 (LGPL-3.0) compiled to WebAssembly — loading and decoding 100% client-side.
