An archive is only useful if it still opens in ten years. Convert your HEIC library to JPG below — but read the note on metadata before you delete anything.

Queued—
JPEG has been readable by everything since 1992 and will be readable by everything for a long time yet. HEIC is younger, patent-encumbered and supported unevenly outside Apple's ecosystem, which is exactly the profile of a format that ages awkwardly.
That is the argument for JPG copies in a long-term archive: not that HEIC will vanish, but that a backup you can open on any machine, in any decade, without installing a codec is worth the extra disk space.
JPG is less efficient, so expect archive copies to be larger than the originals — often two to three times. At 95% the visual difference from the source is nil, but you are spending storage for compatibility.
The bigger cost is metadata. Read the warning below before you treat these JPGs as replacements rather than companions.
Work in batches of fifty or so for a large library. Every HEIC joins the queue automatically.
Take each batch as a ZIP and unzip it into your archive folder alongside the originals.
Do not delete your originals
Conversion strips the EXIF block, so capture dates, GPS coordinates and camera details do not survive into the JPG. For an archive, that is usually the most valuable data in the file — it is what lets Photos, Lightroom or any future software rebuild a timeline.
Keep the .heic files as your master copies and treat the JPGs as compatibility copies. If you want dated JPGs, transplant the metadata with ExifTool: exiftool -TagsFromFile %d%f.HEIC -all:all -ext jpg .
Convert copies, not replacements. JPG guarantees the images open anywhere for decades, which is a genuine archival advantage. But conversion drops all EXIF metadata, so keep the HEIC originals as masters — an archive without capture dates loses much of what makes it an archive.
There is no imposed cap, but for a library of thousands, work in batches of around fifty and save each ZIP before continuing. Everything runs in your browser, so your device's memory is the practical limit.
No. The decoder is a WebAssembly module that runs inside your browser tab, so the photo is read from your device into memory and converted there. You can check it in your browser's Network tab, or disconnect from the internet once the page has loaded and convert anyway.
