Why OPT-IMG Beats Kraken.io

OPT-IMG brings together modern format support, batch workflows, and SEO metadata automation—areas where Kraken.io focuses more on raw compression and developer/API tooling.

Kraken.io

  • Robust compression engine

    Supporting JPEG, PNG, WebP, AVIF, SVG, and more. Strong developer/API features with URL pasting, ZIP upload, resizing, dedicated infrastructure.

  • Primarily API/developer-oriented

    Built for technical workflows with API, ZIP uploads, and resizing pipelines. Less focus on SEO/marketing user needs.

  • Focus on size-reduction

    Emphasis on compression and performance optimisation. Less focus on automation of SEO metadata (filenames + alt text) out of the box.
