About WebP files

WebP is an image format used on websites. It supports transparency and can be lossy or lossless. WebP files can be smaller than JPG or PNG files. People convert WebP files to JPG, PNG, or GIF when a program or device does not open WebP.

People also convert JPG, PNG, and GIF files to WebP. WebP keeps transparency and can make smaller files for a website. The converter runs in the browser and the conversion runs on our servers. You do not need to install anything. Uploads and downloads use HTTPS. No watermark is added on any plan.

How we convert WebP to other formats

Output formats

JPG, PNG, WebP, and GIF. JPG cannot store transparency. PNG is lossless. WebP supports transparency and can be lossy or lossless. GIF has a limit of 256 colors.

Quality

JPG and WebP default to quality 85. PNG is lossless. GIF has no quality setting.

Transparency

PNG and WebP keep transparency. JPG needs a flatten option with a background color, white by default.

Size

Pixel size stays the same unless you set a smaller size. We do not enlarge images.

Measured

In benchmarks, image conversions finished in under 4 seconds including queue time. A 28 KB WebP became a 242 KB PNG in about 3.7 seconds. A 212 KB PNG became a 33 KB WebP.

Common problems and fixes

Transparent areas look wrong in the JPG.

On the WEBP converter page, enable the flatten option and choose a background color such as white to control the fill.

The output file is much bigger than the input.

PNG is lossless and WebP usually is not. Use the palette option for simple graphics, or use JPG for photos.

An older program cannot open the WebP.

When using the WEBP converter page, keep the PNG for that program and use the WebP only on your website.
