PicSmaller DESKTOP · WINDOWS / MACOS

Desktop goes beyond the web — more formats, more power, fewer limits

The web version handles everyday quick tasks. The desktop app is built for professionals: broader format support, larger files, faster processing, and AI-powered features like background removal, watermark cleanup, and upscaling — all impossible in a browser.

  • 16+ formats including RAW, HEIC, PSD (web: only 6)
  • No file size or count limits (web: constrained by browser memory)
  • AI background removal / watermark cleanup / upscaling (web: unavailable)
  • Full offline capability + high-speed folder batch processing
