Formats and Output

SaneClick accepts JPG, JPEG, PNG, HEIC, HEIF, TIFF, TIF, GIF, BMP, and WebP files that macOS can decode. Conversion runs locally using Apple's image frameworks. No separate command-line image tool is needed.

The conversion creates a still image. For an animated GIF or a file containing several images, it uses the first image. JPEG conversion is lossy; keep the original if you need its original quality or metadata.

Choose the Right Tool

Preview is a good fit when you want to choose export settings. SaneClick suits repeated PNG or JPEG conversions from Finder without opening another image editor.
