Image Format Conversion
The process of re-encoding an image from one file format to another, typically for compatibility, size reduction, or feature requirements.
Image format conversion changes the encoding of image data from one format to another. Common examples include HEIC to JPEG for compatibility, and JPEG to WebP for size reduction. The process involves three stages: decode (decompress source), pixel buffer, and encode (compress to target format).
Converting between lossy formats (e.g., JPEG → WebP) introduces generation loss since already-discarded information cannot be recovered, and re-encoding adds further degradation. Minimizing conversion steps and converting from RAW or lossless sources when possible preserves maximum quality.
The image conversion tool handles mutual conversion between JPEG, PNG, WebP, AVIF, and other major formats in the browser. For iPhone HEIC files, the HEIC-to-JPG tool provides one-click conversion.
