Compress WEBP images

压缩 WEBP 文件，上传更快，画面依然自然。

快速解答

To compress a WEBP, upload it to ezimagetools.com, choose how hard to squeeze it, and download the smaller file. WEBP is already an efficient format, so a second pass wins less than the same pass would on a JPG or a PNG. The width and height never change — only the file size does. It is free, needs no account, and your upload is deleted within an hour.

如何压缩 webp

  1. Add your WEBP files

    Tap the upload box and pick the WEBP images you want smaller, or drag them in.

  2. Choose how much to shrink

    Recommended is the best balance. Smallest file goes further when size matters more than detail.

  3. Press Compress

    You will see exactly how many kilobytes each file lost before you download anything.

  4. Download

    Save the smaller WEBP files. A batch comes back as one ZIP.

What a WEBP is

WEBP is Google's web image format. It does everything JPG and PNG do — lossy or lossless, with or without transparency — in roughly 25 to 35% fewer bytes, and every browser released since 2020 displays it.

What we do to your file

We re-encode the picture with an optimised encoder, strip out the camera and location metadata you probably did not mean to publish, and convert the colour profile to standard sRGB so it looks the same everywhere. The picture itself is never cropped or resized.

常见问题

How does compressing a WEBP work?

WEBP is already an efficient format, so a second pass wins less than the same pass would on a JPG or a PNG. It is still worth doing when the original was exported at a high quality setting, which design tools do by default.

Will compressing my WEBP make it look worse?

Not at the Recommended setting. WEBP is a lossy format, so something is always discarded, but the encoder starts with the detail your eye is least able to see. Push it to Smallest file on an image with large flat areas and you may start to notice banding.

How much smaller will my WEBP get?

A photo usually drops by 60 to 80% at the Recommended level. Pictures full of fine detail — foliage, gravel, hair — compress least, because there is little the encoder can safely simplify.

Does compressing a WEBP change its dimensions?

No. Compression changes only the number of bytes the file takes up. The width and height in pixels are untouched. Use the Resize tool if you want fewer pixels, and do that first — resizing then compressing beats compressing alone.

Can I compress a WEBP to an exact size in KB?

Yes. Enter a target size and the compressor searches for the highest quality setting that still fits under your limit. That is more reliable than guessing at a quality number, especially when an upload form has a hard cap.

Is it safe to compress WEBP files online?

Yes. Your file is processed on our server and deleted automatically within one hour. We never look at it and there is no account to create.
