Quick Comparison

Why OPT-IMG Beats ShortPixel

OPT-IMG combines modern-format compression with full SEO-metadata automation (filenames + alt text) and is platform-agnostic—where ShortPixel is strong at bulk image compression but lacks the SEO filename & alt-text automation across any CMS.

ShortPixel

  • Excellent bulk compression

    Bulk image compression (JPEG/PNG/WebP) with WordPress plugin focus. Built mainly for WordPress—some external uploads but plugin-centric.

  • WordPress-centric

    Built mainly for WordPress workflows. Some external uploads supported, but focus is plugin-centric rather than platform-agnostic.

  • Focus on file size reduction

    Emphasis on file size reduction and conversions. Less emphasis on filename/alt-text automation for SEO.

OPT-IMG

  • 3-in-1 compression + SEO

    Compression + AI-generated SEO filenames + AI alt text for any CMS/site. Built for complete image workflows.

  • Fully platform-agnostic

    Works across any CMS or website—ideal for agencies, eCommerce stores, blogs, and real-estate listing sites.

  • SEO, accessibility & performance

    Emphasis on SEO, accessibility and performance: automated naming & descriptions + modern formats + batch ZIP downloads.
