Check the category first
Make sure Photos is a large part of iPhone Storage. If another app dominates, reviewing your library may not solve the warning.
Inspect the largest clips
Play the beginning, middle and end. A long recording may contain an important segment after an uninteresting opening.
Choose a role for each file
Keep an original for editing, export an independent archive, or make a smaller sharing copy. These are different goals.
Verify before removing
Play any replacement and check its audio and quality. Creating a copy alone increases usage until you decide what to do with the original.
Choose the right action
| Your priority | A useful approach | Before you act |
|---|---|---|
| Keep the original | Retain the full-quality or meaningful version; review replaceable content elsewhere first. | A smaller copy may not preserve edits, movement or all detail. |
| Remove an unwanted item | Inspect it, verify any necessary independent copy and approve only the intended selection. | Deletion in a synced library can affect other devices. Permanent removal ends recovery. |

Questions you might still have
Why did compression use more space at first?
The smaller result and original can coexist. Keep enough working space and inspect the result before removing anything.
Can a browser calculator shrink a video?
No. It estimates file size from duration and bitrate; it does not encode or upload the file.
