Best Image Format for Email
Email clients are conservative. The best image format for email prioritizes open-everywhere compatibility over cutting-edge compression.
Quick take: Photos → JPG. Graphics/transparency → PNG. Convert HEIC/WebP/AVIF before attaching.
Photos
JPG remains the lingua franca of email photo attachments and many newsletter uploads.
Screenshots and logos
PNG keeps text readable and preserves transparency. Avoid heavy photo PNGs when JPG would suffice.
iPhone and modern formats
Convert HEIC → JPG and WebP → JPG when sending to mixed Windows/mobile audiences.
Key points
- JPG for photos; PNG for UI/logos.
- Convert niche formats first.
- Resize before attaching.
