Question 1

How do I compress a WebP image?

Accepted Answer

Upload one or more WebP files, then adjust the quality slider (10-100%). Lower quality produces smaller files. The preview updates instantly so you can see the size savings and visual quality side by side.

Question 2

Can I compress multiple WebP files at once?

Accepted Answer

Yes. Drag and drop multiple WebP images and every file is compressed with the same quality setting, with a per-image savings breakdown. Download each result individually.

Question 3

Is my WebP image uploaded to a server?

Accepted Answer

No. All WebP compression runs entirely in your browser using the Canvas API. Your images never leave your device.

Question 4

What quality should I use for WebP?

Accepted Answer

For web use, 75-80% quality gives excellent compression with minimal visual loss. WebP at 75% is typically 25-35% smaller than JPEG at the same quality, making it ideal for websites and performance-focused projects.
