Frequently Asked Questions

What is WebP?▼

WebP is an image format developed by Google that provides superior compression. WebP images are typically 25-35% smaller than equivalent JPEG images with the same visual quality. It supports both lossy and lossless compression, as well as transparency.

What is AVIF?▼

AVIF (AV1 Image File Format) is a newer image format based on the AV1 video codec. It offers even better compression than WebP, typically 30-50% smaller than JPEG. While browser support is growing rapidly, it may not work in older browsers.

Which format should I use?▼

For maximum compatibility, use WebP - it works in all modern browsers. For the smallest file sizes and you can provide a fallback, use AVIF. Many sites use both with the HTML picture element for best results.

Will I lose image quality?▼

At 85% quality (our default), you typically cannot see any difference from the original. For photos, even 75-80% quality looks great. For images with text or sharp edges, use higher quality (90-100%) or lossless mode.

Is my data safe?▼

Yes! All image conversion happens directly in your browser using the Canvas API. Your images are never uploaded to any server. This also means the tool works offline once loaded.

What image formats can I convert?▼

You can convert JPEG, PNG, GIF, BMP, TIFF, and even existing WebP images. The tool accepts most common image formats that browsers can display.
