Which Should You Choose?
Choose ShortPixel if AVIF support matters, you need PDF optimization, you want granular control, or you optimize more than 25MB of images per month. Choose Imagify if you want a simple set-and-forget tool, prefer an all-in-one CDN plus optimization, and your volume fits the free tier.
The Pre-Compression Advantage
Both plugins optimize images after upload. For maximum quality, pre-compress before uploading to WordPress: use a free client-side tool like CompressNeo to convert to WebP/AVIF and hit exact sizes, resize to your exact thumbnail dimensions, upload the optimized files, then let ShortPixel or Imagify handle delivery and fallbacks. This two-layer approach keeps source quality high while plugins manage WordPress-specific delivery.
Pre-compress free, before you upload
CompressNeo compresses JPG, PNG, WebP, and AVIF in bulk - 100% in your browser, no uploads, no watermarks, no limits.
