Question 1

What is WebP?

Accepted Answer

WebP is a modern image format developed by Google, providing superior lossy and lossless compression. WebP lossless images are 26% smaller than PNG, and WebP lossy images are 25-34% smaller than JPEG at equivalent quality.

Question 2

What is AVIF? How does it compare to WebP?

Accepted Answer

AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec. At the same quality, AVIF is typically 20-30% smaller than WebP, supporting HDR and wider color gamut. However, AVIF encoding is slower than WebP and has slightly lower browser compatibility.

Question 3

Is PixConvert safe? Are my images uploaded?

Accepted Answer

Absolutely safe. All image conversion happens locally in your browser. Images are never uploaded to any server, stored, or transmitted. This is one of PixConvert's core advantages over other online tools.

Question 4

What image formats are supported for input?

Accepted Answer

Supports JPG, JPEG, PNG, GIF, SVG, ICO, BMP, AVIF, WebP and other mainstream formats.

Question 5

Can I batch convert? Is there a limit?

Accepted Answer

Yes! PixConvert supports batch processing with theoretically no limit. However, we recommend no more than 200 images at once to maintain optimal browser performance.

Question 6

Are WebP and AVIF supported in all browsers?

Accepted Answer

WebP has over 96% browser support (Chrome, Firefox, Safari, Edge). AVIF has about 93% support (Chrome, Firefox, Safari 16.0+). For unsupported browsers, we recommend using the picture tag to provide a fallback.

Question 7

Will the image quality decrease after conversion?

Accepted Answer

In lossy mode, there may be slight quality degradation depending on your quality setting. However, most people cannot distinguish differences above 80% quality. You can also choose lossless mode to preserve original quality.

Question 8

Is PixConvert completely free?

Accepted Answer

Yes, completely free! PixConvert is a pure frontend tool with no server costs, so it can remain free forever.
