SnapOtter 2.0 turns the image toolkit into a full file-manipulation suite: 200+ tools across five modalities (Image, Video, Audio, PDF, and Files), rebuilt on Postgres 17 and a Redis-backed job queue, with a one-command `docker run`. This is a major release; read Breaking changes before upgrading from 1.x.
- **Four new tool modalities**: Video, Audio, PDF, and Files join Image, taking the catalog to 200+ tools.
- **Durable background jobs**: A Redis-backed queue (BullMQ) runs every tool as a tracked job with live SSE progress.
- **All-in-one single-container mode**: One `docker run` boots a complete instance with embedded Postgres and Redis.
- **On-demand AI bundles**: Background removal, OCR, transcription, upscaling, face detection and enhancement, object eraser, colorize, and photo restoration install from the UI. GPU acceleration is detected per framework.
- **Sign PDF**: Draw, type, or upload a signature and place it on a PDF in the browser.
- **Automate**: A visual pipeline builder that chains tools, with nine prebuilt templates.
- **83 one-click conversion presets**: Dedicated JPG-to-PNG, MP4-to-GIF, and similar converters with fuzzy search.
- **Layer-based image editor**: A Konva-powered editor at `/editor` with brushes, shapes, adjustments, filters, and curves.
- **Files library**: Save any result and reuse it as input to another tool.
2.0 replaces the embedded SQLite database with Postgres 17 and adds Redis 8 for the job queue. Your 1.x data migrates automatically on first boot, but the container stack changed, so back up your whole `/data` volume first (1.x runs SQLite in WAL mode, so the committed data usually lives in `snapotter.db-wal`). Then pick the single-container image (embedded Postgres and Redis, root only) or the Compose stack (app plus Postgres 17 and Redis 8). See the [migration guide](https://github.com/snapotter-hq/SnapOtter/blob/main/MIGRATING.md) and the [upgrade guide](/guide/upgrading).
- **Image editor** - Layers, brushes, shapes, adjustments, filters, curves, keyboard shortcuts. Runs in your browser, processes on your hardware.
- **OIDC / SSO authentication** - Login with Google, GitHub, Okta, or any OpenID Connect provider. Set a few env vars and your team uses their existing accounts.
- **Meme generator** - 100 built-in templates with text rendering via opentype.js. Or upload your own image.
- **Beautify** - Drop a screenshot in, get a polished image out. Device frames (macOS, Windows, browser), shadows, gradients, social media presets.
- **Color blindness simulation** - Preview how images look with protanopia, deuteranopia, tritanopia, and other color vision deficiencies.
- **PNG transparency fixer** - Detects fake-transparent PNGs and fixes them with BiRefNet HR-matting. Optional watermark removal via LaMa inpainting.
- **AI canvas expand** - Extend image boundaries with AI fill. Three quality tiers (fast, balanced, quality) depending on how much GPU time you want to trade.
- **20 languages** - Arabic, Chinese (Simplified/Traditional), Czech, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Thai, Turkish, Ukrainian, Vietnamese. RTL works for Arabic.
- **URL import** - Paste URLs into the dropzone or bulk-import from a list. Server-side fetch with SSRF protection.
- **Multi-file eraser** - Draw erase masks across multiple images, process them all with one click. Strokes persist per-image.
- **Pipeline import/export** - Save tool chains as JSON, share them with others.
- **17 new camera RAW formats** via exiftool, plus QOI, JP2, EPS, DDS, CUR, DPX, FITS, PPM/PGM/PBM, SVGZ, and APNG input. New output codecs for BMP, ICO, JP2, QOI. AVIF, TIFF, GIF, JXL, and PSD export recovered from a previously lost branch.
- **Image enhancement** - Replaced the old pipeline with CLAHE + normalise + gamma. New Deep Enhance toggle uses the AI model for more aggressive results.
- **Restore photo** - Scratch detection rewritten with 8-angle Otsu filtering. LaMa inpainting now runs at native resolution.
- **Exotic formats everywhere** - OCR, image-to-PDF, favicon generator, composition, stitch, and vectorize all decode HEIC, RAW, PSD now.
- **Compress** - Target-size tolerance tightened from 5% to 1%. Target size is the default mode. Added stepper buttons and KB/MB unit selector.
- **Sentry cleanup** - 644 non-actionable events filtered. Real errors now handled properly.
- **GPU detection** - Better diagnostics for containers where CUDA is present but nvidia-smi is not.
- **Auth-disabled mode** - Anonymous user is seeded in the DB with admin role. API keys, pipelines, and user files no longer break on FK constraints.
Unified Docker image with GPU auto-detection. One image handles both CPU and GPU workloads. Simplified compose to a single file with log rotation. Model pre-downloads now include verification and a smoke test.
Role-based access control (RBAC). 14 granular permissions, three built-in roles (admin, editor, user), custom role support. Permission checks on all API routes. Frontend tabs filtered by user permissions.
