IMAGE GUIDE ✦

Image Format Conversion: Choosing JPG, PNG, WebP or AVIF

Image formats solve different problems. JPG is a familiar choice for photos, PNG is useful for lossless graphics and transparency, WebP is efficient for modern web delivery, and AVIF can offer strong compression in compatible environments.

A converter changes the file format; it does not magically improve the source. The best output depends on whether you care most about compatibility, transparency, losslessness or file size.

Choose the output based on the job

JPG: broad compatibility and efficient photographic images.
PNG: lossless pixels, sharp graphics and transparency.
WebP: modern web delivery with lossy/lossless modes and alpha support.

FAQ

Frequently asked questions

Which image format is the smallest?

There is no universal answer. The image content, quality target, transparency and encoder all matter. Modern WebP or AVIF can be very efficient, while PNG is often larger for photos.

Which format is best for transparency?

PNG and WebP both support transparency. JPG does not.

Which format is most compatible?

JPG and PNG have exceptionally broad compatibility. WebP is also widely supported in modern browsers, while some older applications can still lag behind.

Does conversion resize my image?

No. Converting format and changing dimensions are separate operations.

Do the files leave my device?

The conversion workflow is designed to process the image in the browser instead of uploading it to an image-processing server.
