Why HEIC to WebP fits modern websites
HEIC is not a standard website delivery format, while WebP is broadly supported in browsers and common CMS workflows. Converting HEIC to WebP makes iPhone photos easier to publish online.

When WebP is better than JPG
WebP is often the better target when your priority is smaller transfer size for websites, landing pages, and content-heavy pages. It is especially practical when browser support matters more than old desktop software support.
When not to use WebP
WebP is not always the safest choice for email attachments, office workflows, or older upload systems. If maximum compatibility matters, HEIC to JPG is still the safer fallback.
Known limitations
Before converting, note these constraints:
- Output behavior follows format capabilities (for example transparency support and lossy/lossless rules).
- Final file size depends on source image content and selected quality settings.
- If compatibility is critical, choose broadly supported targets first (typically JPG).

Frequently Asked Questions
What is WebP?
WebP is a modern image format developed by Google. It provides 25-34% smaller file sizes compared to JPG at equivalent quality. WebP is supported by all major browsers (96.5% global support).
When should I use WebP?
WebP is ideal for web use — smaller files mean faster page loads. For sharing via email or messaging, JPG is more universally compatible.
Why is the output file sometimes larger than the original?
The output file becomes larger for three clear reasons: (1) Converting from a lossy format (JPG, WebP) to a lossless format (PNG) preserves every pixel, so file size increases in exchange for zero quality loss. (2) AVIF uses the AV1 codec, which has encoding overhead for small or simple images. AVIF delivers its strongest compression gains on high-resolution photos, with 20–50% better compression than JPEG in benchmark comparisons. (3) If the source is already heavily compressed, re-encoding does not reduce size further. PicShift uses industry-leading WASM encoders (MozJPEG, OxiPNG, libwebp) to produce the smallest possible output at your chosen quality. In compress mode, PicShift automatically keeps the original file when compression increases size. Learn more: https://picshift.app/docs/size-increase-explainer/
