JPG vs PNG vs WebP vs AVIF

Different image formats are useful for different purposes. Choose the format that best matches how you plan to use the image.

JPG / JPEG

A popular format for photographs, sharing, email attachments and general image use.

PNG

Useful for graphics, screenshots, logos and images that require transparency.

WebP

A modern image format commonly used on websites because it can offer good quality with smaller files.

AVIF

A modern image format designed for efficient compression and high-quality web images.

When Should You Convert an Image?

You may need image conversion when a website, app or platform requires a particular file format, when you want to use a newer web image format, or when you need a format that supports transparency.

If you only want to reduce the size of an image, use our free image compressor. If you want to combine photos into a document, try the Image to PDF converter.

You do not need to create an account to use the QuickFileTools Image Converter, and the tool does not add a QuickFileTools watermark to the converted image.
