Pros & Cons
theimageoptimizer
Pros
No account required to use the standalone web-based image compressor
States that uploaded images are never stored on its servers
Pay-as-you-go credits never expire, alongside monthly Standard/Agency plans
Dedicated Agency plan with multi-license management and consolidated billing for agencies managing several sites
Automatically converts images to modern WebP/AVIF formats
Cons
Paid use of the WordPress plugin and higher-volume compression relies on a credit-based license system rather than a flat subscription
Specific compression algorithm and quality-level details are not published on the site
No manual control over compression level is mentioned — format/quality selection is automatic
Screaming Frog
Pros
Extremely detailed crawl data and granular control over crawl settings
Flat annual per-seat fee rather than consumption-based pricing
Runs locally, keeping crawl data off third-party servers
Industry-standard tool with extensive documentation and community knowledge
Highly configurable to mimic different bots and rendering modes
Cons
Desktop-only, with no native cloud or SaaS dashboard
Steep learning curve for SEO beginners
Can be memory-intensive on very large crawls without database storage mode
Free version limited to 500 URLs per crawl
No built-in rank tracking or backlink index, requiring separate tools
