WebP is already small — why compress further?

Even WebP files from cameras or exports can be optimized further. Re-compressing at a tuned quality level often cuts 20–40% with no visible loss.

Is the conversion private?

Yes. Your files are processed securely and deleted after conversion. We never share your photos.

Is there a file size limit?

Free accounts can upload files up to 50 MB. Paid users can upload up to 200 MB.

What quality should I use?

Around 80 is a good balance for photos, and 60–70 still looks fine for thumbnails and previews. Very high values (95 and up) grow the file quickly with little visible gain.

Why did my WebP lose fine texture after compressing?

At lower qualities the encoder smooths away fine grain and texture first. Raise the quality to 85–90 for texture-heavy photos such as fabric, foliage or skin.

The file barely shrank — why?

The source WebP was probably already encoded efficiently, so recompressing at a similar quality gains little. Choose a clearly lower quality, or reduce the pixel dimensions first with the Resize Image tool.

Can I compress a batch of WebP files?

Signed-in users can batch-compress up to 5 files on the free plan and up to 100 on a paid plan, downloaded together as a ZIP.

Smart re-encoding, not blind recompression

Because WebP is already an efficient format, the tool lets you pick the exact quality that fits your use case instead of a one-size-fits-all pass.

Re-encoding finishes quickly for typical images. Paid accounts can also compress up to 100 WebP files in one batch, downloaded as a ZIP.

Encrypted upload, automatic cleanup

Uploads travel over HTTPS, and both the original and compressed WebP are deleted automatically within 24 hours.

Free to start

Anonymous visitors get 1 free server-side compression, and free accounts receive 3 conversions every 30 days.

No app to install — compress a WebP straight from the browser on your phone, tablet or desktop.

Settings guide

About the formats

WebP

WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. At comparable visual quality it usually produces noticeably smaller files than JPG or PNG.

Every current browser supports WebP, which makes it an excellent default for web delivery. Outside the browser the picture is mixed: older desktop software, some email clients, and legacy systems may fail to open it. If a recipient cannot view a WebP file, convert it to JPG for photos or to PNG when transparency must be preserved.

Troubleshooting

The output looks softer or loses fine texture: At lower qualities the WebP encoder smooths away fine grain and texture first. Raise the quality to 85–90 for texture-heavy photos such as fabric, foliage or skin, and keep lower values for graphics and simple scenes.
The file barely shrank: The source WebP was probably already encoded efficiently, so recompressing at a similar quality gains little. Choose a clearly lower quality, or reduce the pixel dimensions first with the Resize Image tool — fewer pixels save far more than a few quality points.
The recipient cannot open the WebP file: Some older applications and systems still lack WebP support. Convert the file to JPG or PNG with the Image Converter before sharing it with software you cannot verify — those two formats open everywhere.
