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 WebP to AVIF?
AVIF can reduce transfer size compared with WebP for some sources and settings. The result is not guaranteed, so compare actual outputs.
Should I keep WebP instead?
Use WebP when compatibility requirements include environments that do not support AVIF.
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
