Clean up your Chrome and Safari bookmarks.
Find duplicates and dead links, keep what you want, and bring a tidy set back to your browsers. It works on its own copy, so your browsers are never changed.
Fulwave BookmarkManager reads your Chrome and Safari bookmarks into its own library. Your browsers are never changed. When you are happy, it writes a file for Chrome or for Safari, and you import it.
It finds duplicates, with a keeper chosen for each group, and checks every link. It can tell a missing page from a missing site, and it offers a live page nearby or, if you allow it, an archived copy. Mark a bookmark OK and it stops being flagged.
Clean up one browser, make it your master, and match another browser to it. See what is new in Chrome, bring in what you want, and export a file that makes Chrome match.
See everything in one list, or as folders laid out like Chrome (Bookmarks bar, Other bookmarks) or Safari (Favorites, Bookmarks Menu). Sort by title or by the date each bookmark was added.
Every import shows what would change before it happens. Undo what you do. Save your work as a file that keeps your notes and results, and, if you like, have the app open that file whenever it starts.
No account and no analytics. Your bookmarks stay on your Mac. Link checks go straight from your Mac to the sites you bookmarked, and looking up archived copies is off until you turn it on. Once a day the app checks fulwave.com for a newer version, and you can turn that off. See the privacy policy.
