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.

Convert iPhone HEIC photos to WebP. WebP may reduce size for web use, but the result depends on the source, encoder settings, and target support.

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 an image format developed by Google that supports lossy and lossless compression. It can be smaller than JPG for some sources and settings. Check the actual output and verify support in the browsers or apps you target.
When should I use WebP?
WebP is useful for web delivery and may reduce payload size for some images and settings. Compare the output and verify target support; JPG can be more compatible with older sharing workflows.
Why is the output file sometimes larger than the original?
Output can grow when a lossy source is written to lossless PNG, when codec or container overhead dominates a small image, or when the source is already efficiently compressed. Results depend on the image, format, and settings; no fixed saving is guaranteed. PicShift uses MozJPEG, OxiPNG, and libwebp-based workflows, but those implementation choices do not guarantee the smallest possible file. In compress mode, PicShift keeps the original when the generated result is larger. Learn more: https://picshift.app/docs/size-increase-explainer
