HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. It uses the HEIF (High Efficiency Image Format) standard developed by the Moving Picture Experts Group (MPEG). HEIC files are roughly half the size of equivalent JPEG files at the same visual quality, which is why Apple switched to it- iPhone storage is limited and HEIC saves significant space.
WebP is Google's modern image format supported by all major browsers since 2020. It produces files 25–34% smaller than JPEG at equivalent quality- making it ideal for websites, e-commerce product images, and any web publishing workflow. If you're optimizing iPhone photos for the web, converting HEIC directly to WebP skips an intermediate JPG step and preserves more quality.
omnikitbolt uses a server-side conversion pipeline powered by heic-convert, a pure JavaScript/WebAssembly library that does not require native system libraries. This means it runs reliably on any server and produces consistent output.
Your HEIC file is sent over an encrypted HTTPS connection, converted in memory, and the JPG or WebP result is returned immediately. No files are stored on our servers- the conversion is ephemeral. We validate the actual file magic bytes (not just the extension) to ensure only genuine HEIC/HEIF files are processed.
The quality slider controls the compression level of the output file. At 85% (the default), the result is visually indistinguishable from the original at a significantly smaller file size. At 60%, you get the smallest possible file- useful for thumbnails or email attachments. At 100%, virtually no lossy compression is applied.
