This plugin enables content and marketing teams to quickly detect heavy images and missing alt text directly in the WordPress Media Library. With sorting, filters, bulk actions, dashboard widgets and downloadable reports, you can keep your images optimized for better performance, accessibility and image SEO.

You can:

Sort the Media Library by file size to easily identify large files.
Filter images that don’t have alternative text (alt text).
Use size-based filters (for example: optimal size, medium size, large size) to prioritize which images to optimize first.
Run a Bulk Action in the Media Library to calculate file sizes for existing uploads.
Export CSV reports including file size, format (MIME type), URL, alt text, image date, post title and post URL — ideal for audits or sharing with your team.
See a summary of your Media Library in a dashboard widget, including how many images are heavy or missing alt text.
Configure weekly or monthly email reports so you can monitor the optimization status of your images without logging into WordPress.

Evaluate results

Recommended Tools
– Lighthouse (in Chrome DevTools) — Analyze image weight and format, as well as the use of alternative text (ALT).
– WebPageTest — Check how images affect real-world load times.
– Squoosh — Compare visual quality and file size savings when optimizing images.
– WAVE Accessibility Tool — Verify whether images are missing ALT attributes or if the alternative texts are descriptive.

Evaluation Guidelines
– Identify images without ALT text or with excessive file size before running external tests.
– After replacing large images or adding ALT text, repeat your evaluations to confirm improvements.
– Evaluate both new and existing content — not only the most recent uploads.
– Define an internal size limit (for example, 200 KB per image) and monitor it regularly.
– Keep in mind that accessibility also affects SEO and overall user experience.
