RetouchEngine

Photo adjustments as an API. Documented pixel math — never generative AI. The same call always returns the same image.

Quick start

curl -X POST https://retouchengine.com/v1/edit \
  -H "X-API-Key: rte_..." \
  -F "image=@photo.jpg" \
  -F 'ops=[{"op":"autotone"},{"op":"clarity","amount":0.5}]' \
  -o edited.jpg

What you get

• 22 operations — tone (exposure, contrast, highlights, shadows, autotone…), color (vibrance, warmth, mono…), detail (clarity, sharpen, denoise), geometry (crop, aspect, rotate, flip), finish (vignette, grain) and person_light (brighten only the person, never blows highlights).
• Presets — baseline, punchy, soft_portrait, classic_bw, golden_hour, subject_pop.
• Determinism — identical input and parameters give identical output, always.
• Privacy — EXIF is stripped from every output; images are processed in memory and never stored.
