HEIC vs JPG vs WebP: which image format should you use?
A practical comparison of HEIC, JPG and WebP for compatibility, quality, transparency and file size.
Last reviewed: 2026-07-29Use HEIC when you want efficient storage inside the Apple ecosystem, JPG when universal compatibility matters most, and WebP for modern websites that need small files, transparency or animation.
What each format is best at
HEIC can store high-quality photos efficiently and is common on recent iPhones. JPG is the safest choice for sharing photographs across old and new software. WebP is designed for the web and supports both lossy and lossless compression, transparency and animation.
A format is not automatically better because its file is smaller. The right choice depends on where the image will be opened, whether transparency matters and whether repeated editing is expected.
Compatibility and conversion
JPG remains the least surprising format for email attachments, customer uploads and older applications. WebP works well in modern browsers and many design tools. HEIC compatibility is improving, but some websites and Windows workflows still request JPG.
Conversion cannot restore detail already removed by compression. Keep the original HEIC if it is your master photo, then create a JPG or WebP copy for delivery.
Privacy when converting
A browser-local converter keeps the photo on your device. This matters when images contain faces, documents or location metadata. Always check whether a service uploads files before using it for sensitive material.
