Try all 10 tools in your browser
Grouped into three families. File tools keep documents in the tab — nothing is sent to UtilForge servers.
Workflow
The basics of being readable by AI search — structured data, llms.txt, and AI-crawler control — as tools you own. Also covers WCAG contrast. Structured data helps machines understand pages; it does not guarantee rankings, AI citations, or rich results.
Robots.txt Generator
Decide which AI bots can read your site. Copy one file.
Guides crawlers that obey robots.txt — not a security lock or ranking switch.
Open tool → 02LLMs.txt Generator
Give AI assistants a clean map of your site in one Markdown file.
Emerging convention — adoption uneven; no ranking or citation guarantee.
Open tool → 10JSON-LD Schema Generator
Describe your page to search engines in their format. Copy, paste, validate.
Helps machines understand pages — does not guarantee rankings or rich results.
Open tool → 09WCAG Contrast Checker
Check whether your text is readable, and get the nearest colour that passes.
Open tool →Private file tools
Run entirely in your tab — turn off Wi‑Fi and they still work.
Compress PDF
Shrink a PDF without uploading it anywhere.
Raster modes can lose selectable text; large files may hit tab memory.
Open tool → 04HEIC to JPG
Turn iPhone photos into JPGs that open everywhere, privately.
Live Photos: primary still only. Files never leave this tab.
Open tool →Privacy tools
Free checks that stay in your browser — separate from the SEO Utility Pack.
Is your redaction real?
Check whether blacked-out text in a PDF can still be recovered. Free, no upload.
A clean result is not a safety certification. Flagged means text sits under something opaque — check it yourself.
Open tool → ★Redaction Studio
Apply real redactions in your browser — rasterise so the text is gone, not just covered.
Paid tool. File stays in this tab.
Open tool → ★AI access checker
Paste a robots.txt and see which AI crawlers are allowed, blocked, or unclear.
Open tool →Calculator pages
Useful, linkable pages you can put on a site — not SEO magic.

Presets are not live feeds — not tax advice.
Open tool → 05Overtime Pay Calculator
