Frequently Asked Questions
How much smaller is WebP compared to JPG?
WebP is typically 25-34% smaller than JPG at the same visual quality. A 1 MB JPG might become 650-750 KB as WebP with no visible difference.
Why is the output file sometimes larger than the original?
This can happen for a few reasons: (1) Converting from a lossy format (JPG, WebP) to a lossless format (PNG) preserves every pixel, which naturally produces a larger file in exchange for zero quality loss. (2) AVIF uses the AV1 codec which has encoding overhead for small or simple images — it excels at high-resolution photos where it achieves 20–50% better compression than JPEG. (3) If the source is already heavily compressed, re-encoding may not reduce the 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 would increase the size.
