Velnor

Velnor checks every image in the folders you choose and shows exactly where space is being wasted — without a single file ever leaving your device.

Velnor is a free, offline image-file auditor. It reads your image library, measures size, dimensions, transparency, format and naming, and then tells you which files can safely be optimized, converted or removed.

Key features

• Deep file analysis — oversized files, huge dimensions, tiny icons, transparency issues, unsupported formats and invalid resource naming, all reported with clear explanations.
• Duplicate and similar detection — finds exact duplicate copies by content hash and near-duplicates with a visual similarity score, so one click shows every redundant copy.
• Health score — every collection gets a clear 0–100 health score with a breakdown by severity, so you always know where to start.
• Real savings estimates — potential recovered storage is calculated for every file and never exceeds the actual file size.
• Full history — every audit is stored locally as a report with asset-by-asset detail, recommendations and searchable lists.
• Bilingual — full English and Arabic interfaces that follow system or in-app settings.

Built for privacy

Velnor has no account, no analytics, no advertising and no network permission. Reports and preferences stay in the app's private storage on your device, and your original files are never renamed, moved, edited or deleted — you always decide what happens to them.

Useful for

• Photographers and content teams building asset libraries
• Android and web developers guessing which images bloat their packages
• Anyone hoarding photos and wondering how much space they really use
