Why convert AVIF to WebP?
AVIF offers the best compression available today, but browser support is still expanding — older versions of Safari, iOS, and some Android browsers do not support AVIF. WebP is supported by all modern browsers since Safari 14 (2020), making it the safer choice for maximum compatibility.
Converting AVIF to WebP is a practical fallback strategy: WebP files are slightly larger than AVIF but significantly smaller than JPG or PNG. WebP supports both lossy and lossless compression, alpha transparency, and millions of colors.
If your audience includes users on older devices or browsers, WebP ensures your images display correctly for everyone. For the latest browsers, you can serve AVIF with WebP as a fallback using the HTML <picture> element.
All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.

Tips for converting AVIF to WebP
- Start with quality 85 – this is typically the sweet spot for WebP compression, offering significant file size reduction with minimal visible quality loss.
- Batch convert for efficiency – if you have many AVIF files, use the batch conversion feature to process them all at once. This saves considerable time compared to one-by-one conversion.
- Compare before downloading – use the live preview to compare the original AVIF with the WebP result. Adjust quality settings until you find the right balance for your specific use case.
- Keep your originals – always save a copy of your original AVIF files. Lossy compression is irreversible, so having the originals allows you to re-convert with different settings later.

Quality settings – what to choose when converting AVIF to WebP?
The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.
- 80% (default) – a good balance for most use cases. WebP at 80% is visually equivalent to AVIF at similar settings, with slightly larger file size.
- 85–90% – for product photography and portfolios where quality takes priority over file size.
- 60–70% – when minimizing file size is the main goal, e.g. thumbnails and preview images.
WebP files will typically be 20–30% larger than the AVIF originals at equivalent quality. This is the expected trade-off for broader browser compatibility.
