Can an Apple Shortcut convert selected ProRAW images into high-quality HEIF copies, save them to an album and preserve the originals?

Every later storage, measurement or deletion feature depends on the core conversion path being safe and repeatable.

A small selected batch was processed one item at a time, converted to HEIF and saved as copies before any experimental behavior was added.

End-to-end compile and runtime testing passed, including album-specific saving with the original photographs retained.

PROVEN

The working conversion path became a protected baseline. New behavior is tested around it instead of rewriting it.

Keep the baseline unchanged while experimental measurements and user controls are developed in isolated revisions.

Can Shortcuts retrieve the resulting file size of a converted HEIF without modifying the original photograph?

A real output measurement makes storage savings more useful and more trustworthy than a prediction based only on the source file.

The File Size detail was read from the converted HEIF immediately after conversion inside the existing per-photo loop.

The converted HEIF exposed a File Size value in bytes during runtime. The measurement works; the user-facing unit display still needs another pass.

PROVEN

RawDizzzy can now inspect the generated asset. The test also exposed that raw bytes should be normalized before being shown to the user.

Convert the result cleanly to MB or GB and decide whether the final interface should report each file, the batch total or both.

Can the Photo Archive serve sharp responsive images without publishing original files or embedded location metadata?

The archive needs to look sharp on an iPhone without exposing precise capture location or full-resolution source files.

Each supplied photograph generated 960 px and 1536 px derivatives. EXIF and image-resource metadata were removed while the ICC color profile was retained.

Ten originals produced twenty responsive WebP derivatives. Public files retain their color profile but contain no EXIF or GPS data, and the originals are not served.

PROVEN

Future archive additions now have a repeatable public-image policy: responsive derivatives, preserved composition, no automatic location disclosure.

Reuse the same process for future photographs and add only broad, human-readable locations that are intentionally supplied.
