Why compress WebP images?
WebP is already Google's efficient image format, but a high-resolution WebP from a camera or design tool can still be 1–5MB. For web publishing, social media, or email, keeping WebP under 150–200KB ensures fast load times without visible quality loss. This tool compresses WebP files directly — or converts JPEG/PNG to optimised WebP.
WebP vs JPEG compression: which is smaller?
| Format | Same Quality | File Size Difference | Browser Support |
|---|---|---|---|
| JPEG (quality 85%) | Good | Baseline | Universal |
| WebP (quality 85%) | Good | 25–35% smaller than JPEG | All modern browsers |
| PNG (lossless) | Perfect | 2–5× larger than JPEG | Universal |

How to compress WebP in 3 steps
Upload your WebP image using drag-and-drop or click to browse. The tool also accepts JPEG and PNG — it can output any of these as WebP.
Select WebP as the output format. The quality slider is pre-set to 85% — the sweet spot for visual quality vs file size. For web use, 80–90% is standard.
Click Compress, review the before/after preview, then download. All processing happens in your browser — nothing is uploaded.
Frequently Asked Questions
Does this tool upload my WebP to a server?
No. Your image is compressed using the browser's Canvas API — it never leaves your device. Unlike TinyPNG, Squoosh's server mode, or other cloud compressors, all processing is local. This is important for sensitive images (product photos before launch, personal photos, ID documents).
Can I convert JPEG/PNG to WebP and compress at the same time?
Yes. Upload any JPEG or PNG, select WebP as the output format, set your target quality or size, and click Compress. You get a compressed WebP output in one step — useful for converting a batch of product images or blog photos to WebP format.
What quality setting should I use for WebP?
85% WebP is the standard for web publishing — it's visually identical to the original at normal viewing sizes and achieves excellent compression. For thumbnails or icons, you can go as low as 75%. For print-quality preservation, use 90–95%.
