Utilumo — privacy-first browser utilities, right where you need them.

Clean URLs, work with text and JSON, redact screenshots, process images and launch useful tools directly from your browser. No account, no background monitoring, no unnecessary tab-hopping.

• Clean links — remove tracking parameters, inspect URLs and copy Markdown links
• Work with text — clean copied text, reveal hidden characters, count words and extract URLs
• Developer tools — format JSON, decode Base64/JWTs, convert tables and timestamps
• Privacy screenshots — capture a page or region and cover sensitive information before sharing
• Process images locally — resize, re-encode and remove metadata
• Quick launcher — search, favourite and reopen Utilumo tools from one place

Utilumo only runs when you explicitly invoke it through the popup, side panel, context menu or keyboard shortcut.

• No account or sign-in
• No ads, analytics or extension telemetry
• No browsing-history collection
• No permanent access to all websites
• No clipboard-read permission
• Screenshots, pasted text, images and generated output stay on your device

Some explicitly chosen actions open the matching tool on utilumo.com. When required, the selected URL may be passed to that tool and remains visible in your address bar.

If browser security prevents a task from running locally, Utilumo may request temporary access to that specific website or offer to open the corresponding web tool instead. It never silently uploads your content.

Small tools. Less friction. More control.
