Veltrix is not an artistic photo editor — it's a precision instrument for the unglamorous, repetitive work of getting images and documents into the exact shape institutions demand. Passport photos. Scanned forms. Signatures. Batches of student IDs. The stuff that usually takes an afternoon in fifty browser tabs.
Veltrix does it locally, instantly, and privately — nothing you process is ever uploaded to a server.
Import → Edit → Preview → Save → Organize → Export One pipeline. Zero uploads. Full control.
| Module | What it does |
|---|---|
| 🖼️ Non-Destructive Editor | Original image and processed output are kept fully separate — edit freely, revert anytime |
| ✂️ Smart Crop | Standard crop + 4-corner perspective crop with edge-midpoint handles, fine & 90° rotation |
| 📐 Aspect Presets | Passport (7:9), square, and custom ratios, live-previewed |
| 📄 PDF Import | Drop in a PDF, get each page as an editable item |
| 🗂️ Gallery Engine | Drag-and-drop reordering, duplication, delete/undo |
| 🗜️ Target Compression | Squeeze to 100KB / 200KB / 500KB / 1MB for upload-limit compliance |
| 🏷️ Bulk Rename | Prefix + sequential numbering, gallery-order aware |
| 📦 ZIP Export | Custom filenames, batch download |
| 🖨️ Print Studio | Real-world mm/cm/inch layout on A4/A3/Legal/B4/custom pages, freeform placement, print-ready export |
| 🎯 Auto Crop (in progress) | Photo mode (face detection + passport heuristics) & Document mode (edge/contour detection + straightening) |
| ⚡ Auto-Apply (in progress) | Runs Auto Crop the instant an image is selected — no button press |
┌─────────────────────────────────────────────┐
│ PRIVACY FIRST → processing stays local │
│ SPEED → no round-trip to a server │
│ PRECISION → built for compliance-grade output │
│ NON-DESTRUCTIVE → originalDataUrl ≠ processedDataUrl │
└─────────────────────────────────────────────┘
Every image carries two states under the hood:
originalDataUrl— the untouched source, always recoverableprocessedDataUrl— the saved, edited output
This means you can iterate aggressively without ever fearing data loss.
