Why this tool is useful
Measure bookmark-library clutter before importing it into another browser, while keeping private project, account and reading-history URLs on the current device.
Local File Tools · runs locally
Private Browser Bookmark Export Auditor
Inspect a Chrome, Edge, Firefox or Safari Netscape bookmark HTML export for folder depth, duplicate destinations, empty titles, tracking parameters, credential-bearing URLs and non-web schemes without opening any saved address.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
How it works
A bounded inert tokenizer reads only Netscape bookmark tags and attributes, builds a folder tree, classifies schemes and URL hygiene, and groups normalized destinations locally.
Practical example
Export bookmarks from Chrome, choose ten domains, then review duplicate, tracking, empty-title and folder-depth counts before deciding whether a cleanup is worthwhile.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
