Compressing HEIC to Under 100 KB
At 100 KB we convert HEIC to WebP or JPEG at standard web quality, retaining dimensions up to about 1920 px. This is the practical target for iPhone photos used in articles, products, and galleries. The conversion also normalizes the format for universal browser support. Quality remains high; the main change is the container format and a modest quality reduction from the already-compressed HEIC source.

Frequently Asked Questions
Does converting HEIC lose quality twice?
HEIC is already lossy, so conversion to WebP/JPEG adds a second lossy step. At 100 KB the extra loss is small but real — always keep your original HEIC.
WebP or JPEG from HEIC?
WebP is smaller at equal quality and supports transparency; JPEG has the oldest compatibility. WebP is the tool default for efficiency.
