One keyword, three sites searched at once — automatic bulk download
Still saving free images one by one from Google for your blog, slide decks, or design work? With ImageFlow, you just type a keyword and it searches Pixabay, Pexels, and Unsplash simultaneously, automatically filters out duplicates, and downloads the full-resolution originals in one go.
6.3MB · no install · no ads · no login. Built with Rust + egui, it's about 10x lighter than Electron apps and delivers near-native speed. Two built-in trial API calls are included; after that, grab your own free keys (about 3 minutes) for unlimited lifetime use.
Key Features
Search all three APIs at once & bulk download
- Pixabay (100/min) · Pexels (200/hour) · Unsplash (50/hour)
- Search all three sites with a single keyword, with live per-API progress
- Up to 1,000 images per keyword; queue multiple keywords in sequence
- Pause / resume / stop, and open the folder automatically when done
Two-layer duplicate prevention
- Layer 1: duplicate check by image ID (per API)
- Layer 2: content-based blocking via SHA256 hash
- History is stored permanently, so repeating the same keyword never re-downloads duplicates
Korean-to-English auto-translated search
- Enter a Korean keyword and it auto-converts to English and searches both at once — 2x+ more results
- 50+ built-in translation dictionary (animals, nature, food, interiors, and more)
Fine-grained search options
- Image type (photo, illustration, vector), orientation (horizontal, vertical), and minimum resolution
- Auto-creates a subfolder per keyword; freely set your save path
Live progress dashboard
- Found / downloaded / duplicate / failed stat cards plus an overall progress bar
- Live speed, time remaining, size, and per-API progress
- Dark/light theme, live log (500-line buffer)
