Yes, WebP Files Can Get Smaller Too
WebP is the modern efficiency champion — but efficiency depends entirely on the quality setting chosen at export time. Design tools, screenshot apps, and converters routinely write WebP at quality 90–100, producing files two or three times larger than what the web actually needs. This WebP compressor re-encodes your files at a sensible quality level, typically recovering 30–70% of the size with no visible change.
When to Use This Tool
- Design-tool exports — Figma, Photoshop and friends default to very high quality.
- Converted files — batch converters often use maximum-quality settings.
- Website audits — PageSpeed flagging "efficiently encode images" even though you already use WebP.
- Oversized dimensions — combine quality reduction with the max-width option to fix both problems in one pass.
Quality Guidance for WebP
WebP holds detail better than JPG at equal settings, so you can go lower than you'd expect: 75% is visually transparent for almost everything; 50% still looks good for content images; 25% suits thumbnails. As always, the preview-and-compare workflow wins: compress, view the result, adjust if needed — each pass takes seconds.
