When should you use JPEG?
Choose JPEG for photographs and broad compatibility when you do not need transparent pixels. Use a high enough quality setting, because JPEG is lossy.
Compatibility
Supported by virtually every browser and device.
Convert JPEG images locally
FreeImageKit has a local decode path for JPEG. Exports remove source metadata, and still-image routes do not preserve animation or extra pages.
