Frequently asked questions
- How do I convert HEIC to JPG?
- Upload your HEIC file, select JPEG as the output format, adjust quality if needed, and click process. SnapOtter decodes HEIC natively without sending your file to any cloud service.
- What is the best image format for the web?
- WebP offers the best balance of quality and file size for modern browsers. AVIF is even smaller but has less browser support. Use JPEG as a fallback for maximum compatibility.
- Can I convert RAW camera files?
- Yes. SnapOtter supports CR2 (Canon), NEF (Nikon), ARW (Sony), DNG, and other common RAW formats. They are decoded and converted to your chosen output format.
