How does HEIC conversion work without uploading?

We bundle a JavaScript HEIC decoder (heic2any) that runs locally in your browser. The decoder transforms the HEIC bytes into a regular bitmap, which we then re-encode as JPG, PNG, or WebP using the Canvas API.

Why does HEIC conversion take longer?

HEIC uses the HEVC (H.265) codec, which is far more compute-heavy than JPEG. Decoding a single 4K HEIC photo takes 1–3 seconds on a modern phone; bulk conversions run sequentially to avoid blocking the UI.

Which format should I convert to?

JPG is universal and small. WebP is slightly smaller still but a tiny number of older email clients and tools don't support it. PNG is best when you need transparency or pixel-perfect fidelity (and don't mind a larger file).

Does this preserve EXIF metadata?

No. The Canvas API strips metadata (timestamps, GPS, camera info) — which is often what you want, since EXIF can leak location. If you need to keep EXIF, use a desktop converter.
