Supports HEIC, HEIF, WebP, PNG, JPG, AVIF, BMP
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
Why convert HEIF to WebP?
WebP is broadly supported on the web and reduces transfer size compared with legacy photo formats in standard workflows.
Does WebP keep transparency?
Yes. WebP supports alpha transparency and preserves transparent regions when source content includes them.
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
