What file formats does Dropmatico accept?

Dropmatico supports 5 input formats and 3 output formats. This article explains which formats work, why HEIC is supported, and how format conversion happens automatically.

Input formats

Drop any of these directly into the Single Image Editor or Bulk Image Processor. No intermediate conversion step required.

  • JPEG (the standard web JPEG)
  • JPG (the common extension variant)
  • PNG (lossless, supports transparency)
  • WebP (modern web format, smaller than JPEG at equivalent quality)
  • HEIC (iPhone and modern mirrorless camera output, high efficiency)

Output formats

Every export can target up to three formats simultaneously in the same session. Each format lands in its own folder inside the Master Set ZIP.

  • JPEG: best for photography and web, smallest file size with lossy compression
  • PNG: best when you need transparency or pixel-perfect preservation
  • WebP: best for modern web performance, 30 to 60% smaller than equivalent JPEG

Why HEIC is supported

HEIC is the native format for iPhone photos and for most modern mirrorless cameras. Dropping a raw HEIC directly saves you an export-to-JPEG step in your camera app or Photos library. Dropmatico decodes HEIC natively in the browser, so there's no quality loss from intermediate conversion.

Format conversion happens automatically

When you export, Dropmatico re-encodes your source into the target format. If you drop a HEIC and export to JPEG, the HEIC is decoded, processed, and re-encoded as JPEG in one pass. You don't pick a conversion mode, it just happens based on what you select in the export panel.
