Opera
Built on Chromium, Opera stores a mix of browser caches and local databases under its profile, including HTTP disk cache entries, GPU shader cache data, media cache files, favicon and thumbnail databases, session-related SQLite stores, and IndexedDB or Service Worker data used by sites. These files speed up page loads, video playback, tab previews, and site features, but stale or bloated cache data can leave broken thumbnails, misrendered pages, playback glitches, or oversized profile folders; Kudu removes disposable cache files and can compact fragmented SQLite databases without touching bookmarks, saved passwords, accounts, or personal browsing data you intend to keep.
Why clean Opera?
- Corrupted HTTP disk cache entries can make websites load with missing CSS, broken images, or old page content until Opera fetches fresh copies
- Stale GPU shader and Skia cache data after a graphics driver update can cause black page areas, flickering, or sluggish scrolling until the cache is rebuilt
- Oversized media cache files from streaming sites can consume gigabytes of profile storage and show up as unexpectedly large Opera folders
- Broken favicon and thumbnail databases leave blank site icons, missing Speed Dial previews, or outdated tab thumbnails even though the sites still open normally
- Service Worker and site storage leftovers from changed web apps can keep loading outdated offline assets, causing login loops or pages that refuse to refresh properly
- SQLite databases used for favicons, history-related metadata, and site storage can become page-fragmented over time, and VACUUM rewrites them into a smaller, cleaner file without deleting rows
- Cache growth across many tabs and sessions increases profile scan time at startup, which users notice as a slower launch and delayed restoration of recently used sites
Cache paths Kudu targets
These databases are vacuumed (compacted) — no data is deleted. SQLite VACUUM reclaims wasted space left over from normal usage.
