Compress WebP Images Online

WebP already compresses better than JPG, but a large WebP is still a large file. Reduce its quality or dimensions here, and keep the transparency it supports.

What to Know About Compressing WebP

WebP starts small, so the remaining savings depend on size more than on format.

WebP was designed to replace JPG and PNG on the web, and it usually does both jobs well: at the same visual quality it is typically smaller than JPG, and unlike JPG it supports transparency. That means a WebP file is already an efficient starting point.

Where the remaining savings come from

Because the format is already good, the biggest wins usually come from the image itself rather than the encoder:

  • Dimensions. A 3000-pixel-wide image displayed at 800 pixels is carrying more than ten times the detail it needs. Capping the width in the resize panel is usually the largest single reduction available.
  • Quality. WebP at 70% is often indistinguishable from 90% on a photograph, and markedly smaller. Move the slider down in steps of ten and compare.
  • Re-encoding losses. WebP is lossy by default, so compressing an already compressed WebP adds a second layer of loss. If you have the original JPG or PNG, starting from that is a better idea.

Transparency is kept

Unlike JPG, WebP has an alpha channel. Compressing a WebP that contains transparent areas keeps them transparent, and no background colour is needed or applied. Converting to JPG is the operation that fills transparency with white, and the tool warns you when that has happened.

Browser support

Every current browser displays WebP. The only real limitation is very old software — some offline editors and legacy content systems still do not open it. If you need the widest possible compatibility for a file that will be passed around, JPG remains the safe choice.

WebP Compression FAQ

Does compressing a WebP reduce its quality?

Yes, for the default lossy WebP. The quality slider controls how much detail is discarded. At 80% the difference is usually invisible on a screen. Lossless WebP exists, but browsers do not expose it through the canvas API, so files this tool produces are lossy unless you choose PNG as the output format.

Will my WebP become larger?

It can, especially if the file was already compressed at a lower quality than the setting you choose. This tool measures the actual result and tells you honestly when a file grew, rather than reporting a saving that did not happen.

Is WebP smaller than JPG?

Usually, at the same visual quality — but not always, and not by a fixed amount. It depends on the image. The honest way to find out for your file is to compress it both ways and compare, which takes a few seconds here.

Can I compress an animated WebP?

No. Animated images are refused rather than flattened to a single frame, because silently discarding the animation would be worse than saying no. Still images only.
