Separate submission, publishing, and editing needs so the same conversion lands cleanly.
Photo archives, image format checks, and JXL-capable workflows. It is rarely safe as a direct CMS/browser publishing format; confirm recipient support first.
Use 85-95 for comparisons and 100 when testing lossless-style output. Capture time is useful for organization, but GPS data should be reviewed before public sharing.
For forms and email, a 1600-2400px long edge is practical; for print or archive checks, keep the original dimensions. Keep the original HEIC separately when it matters.

No. Conversion runs in your browser and image files are not sent to a server.
It is rarely safe as a direct CMS/browser publishing format; confirm recipient support first. If the HEIC source is part of an archive, keep the original after conversion. If a submission target specifies format, dimensions, or color requirements, check those first.
