Short answer
The fastest wins are deleting large 4K videos and then immediately emptying the Recently Deleted album (Photos > Utilities > Recently Deleted > Delete All), because items there still count against storage for up to 30 days. Enabling 'Optimize iPhone Storage' under iCloud Photos (Settings > [Your Name] > iCloud > Photos) offloads full-resolution originals to iCloud and replaces them with smaller device copies — often recovering tens of gigabytes in a large library. For quick cache recovery, use Settings > General > iPhone Storage to see the biggest app offenders and reinstall the worst offenders, since iOS has no universal cache-clear button.
PicClear helps with this on your iPhone and works on device for privacy — a pay-once app with no subscription. Test it on a real example and check the current App Store listing for details.
What to look for before choosing
- Delete large 4K videos first — the biggest files; check Settings > General > iPhone Storage > Photos for 'Review Large Attachments'
- Empty Recently Deleted immediately: Photos > Utilities > Recently Deleted > Select > Delete All
- Enable iCloud Photos 'Optimize iPhone Storage' to replace high-res originals with device-sized copies
- Reinstall cache-heavy apps (TikTok, Instagram, Netflix) — delete and reinstall clears accumulated cache that the OS can't purge otherwise
- Clear Safari cache: Settings > Safari > Clear History and Website Data (recovers browsing cache)

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
