v1.17.0 ​

Five new tools, a full image editor, SSO login, 20 languages. Probably should have been three separate releases, but here we are.

New features ​

  • 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.

Improvements ​

  • 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.
  • 2,705+ new tests across unit, integration, and E2E.

Bug fixes ​

  • Upscale on CPU no longer times out on NAS boxes and low-power hardware.
  • QR code logo no longer makes the preview vanish permanently.
  • Crop overflow fixed for tall portrait images.
  • TIFF alpha files correctly force PNG output instead of producing corruption.
  • HDR/EXR decode converts to 8-bit before CLAHE, fixing decode failures.
  • Face landmarks input buffers converted to PNG before the Python sidecar, fixing crashes.
  • Find duplicates handles mixed-format batches and network errors.
  • Beautify preview updates in real time.
  • Progress bars for stitch and vectorize.
  • SVGZ handled by SVG-to-raster.
  • Non-ASCII filenames fixed via percent-encoded X-File-Results header.
