Image Delivery Budget Auditor
Compare supplied image dimensions, bytes and display sizes; prioritize wasted delivery.
Compare supplied dimensions, bytes and display sizes at an explicit DPR. Area-based byte estimates are illustrative, not predicted codec savings or quality judgments.
Using Image Delivery Budget Auditor
Compare supplied image dimensions, bytes and display sizes; prioritize wasted delivery.
- Try the tailored worked example, or open supported local sources. Configuration-only builders start from editable settings. Input schema: url,width,height,bytes,displayWidth,displayHeight.
- Select a Review card for source evidence and supported manual fields. Details & settings controls the thresholds, patterns, URL policy or observation windows; originals stay unchanged.
- Use Preview to inspect the result and method notes. Interactive accessibility prototypes support real keyboard controls; search tools work only with supplied evidence.
- Use Export for the complete workflow ZIP or individual artifacts. Open an exported file before publishing it. Save review retains settings/decisions and source fingerprints; file-based projects need the exact originals to reopen.

Questions & answers
What does Image Delivery Budget Auditor support?
Compare supplied dimensions, bytes and display sizes at an explicit DPR. Area-based byte estimates are illustrative, not predicted codec savings or quality judgments.
What should my input contain?
url,width,height,bytes,displayWidth,displayHeight.
What can I export, and does this change my live website?
Exports include the result data, source fingerprints, decisions and task-specific artifacts such as printable HTML, SVG review evidence, timed VTT notes, JSON-LD, sitemap XML, rule cases or checklists. These pages do not deploy rules, submit URLs, crawl a server or publish content. Public pages retain approved ads and optional consent-based analytics.
What should I verify before relying on the result?
Use the method notes and full evidence. Files are normally limited to eight sources, 25 MiB each and 80 MiB total, with smaller format/graph/image bounds. Worker analyses stop after 30 seconds. Accessibility helpers require real user/assistive-technology review; search evidence cannot guarantee indexing, eligibility, ranking changes or causal effects.
