Why JPG to AVIF is attractive for performance
AVIF can often deliver smaller files than JPG and WebP at comparable visual quality. That makes it attractive when you are optimizing modern web delivery for bandwidth and page speed.
Convert JPG to AVIF
Convert JPG to AVIF when your target platform supports AVIF and you want a smaller modern image format. This is especially useful for performance-focused web delivery where every KB matters.

When AVIF is worth the switch
Choose AVIF when the destination environment is modern enough to support it and you care about stronger compression. It is especially useful for performance-focused sites and asset pipelines.
When WebP or JPG is still safer
If you expect older tooling, plugins, or apps in the workflow, WebP and JPG remain safer targets. AVIF is best when compression matters most and compatibility risk is acceptable.
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 JPG to AVIF?
AVIF uses AV1-based compression and produces smaller files than JPG in standard benchmark comparisons at similar visual quality.
How do I convert JPG to AVIF?
Upload the JPG file, switch the output to AVIF, then download the result. This is useful when your target browser or app supports AVIF and you want a smaller modern image format.
Is AVIF better than WebP or JPG for compression?
AVIF is often better when maximum compression is the goal and the target platform supports it. JPG is easier to open everywhere, and WebP is a practical middle ground when you want modern compression with broader compatibility.
When should I use JPG to AVIF instead of JPG to WebP?
Choose AVIF when the target environment supports it and you want stronger compression. Choose WebP when you need wider practical support across older tools and CMS plugins.
Can I use AVIF on every website or app?
No. AVIF support is broad in modern browsers and newer apps, but some older tools, plugins, and upload pipelines still work better with WebP or JPG.
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
