Reclaim gigabytes of storage in minutes — without giving up your privacy. BulkClean finds the photos your chat apps quietly saved to your library, plus similar shots you took five times, and helps you delete them all on-device. No uploads. No servers. No account. Everything stays on your iPhone. CHAT-SAVED PHOTOS Photos and videos saved from WhatsApp, Telegram, WeChat and other messaging apps pile up over years. BulkClean detects them automatically — by filename fingerprints, never by reading your originals. SIMILAR PHOTOS Burst shots, near-identical selfies, the same sunset five times. Smart on-device hashing groups them so you keep the best and clear the rest. BLURRY PHOTOS Out-of-focus shots and shaky frames hide among your best memories. Deep scan flags likely blurry photos in their own group — sorted worst first — and Smart Select can mark the most obvious ones for deletion. REVIEW BEFORE DELETING Full-screen preview with per-photo selection. File name, date, resolution and size are shown for every photo — you always see exactly what you're removing. Deleted items stay in Recently Deleted for 30 days. PRIVACY BY DESIGN All analysis runs locally. We never upload a single photo, and we don't even read your originals — thumbnails only. BUILT FOR BIG LIBRARIES Scans 30,000+ photo libraries smoothly. Interrupt a deep scan anytime — it resumes in seconds, not minutes. PRICING Free: 10 deletions per day. Pro: one-time purchase, unlimited cleaning forever. No subscription.
