WEBP Optimizer
Drop your .webp files to re-encode at a new quality and size, entirely in your browser. We don't upload or store your images.
Drag & drop WEBP files here
or click to browse. You can recompress and/or resize.
Output Settings
Stability note: We process up to 20 images at a time for reliability. Large batches split automatically.
Higher = bigger file, lower = smaller file.
When aspect is locked, we scale to fit inside your Width/Height. When unlocked and "Fill/Crop" is chosen, we fill the exact size and crop the overflow from center.
Why optimize WEBP?
Re-encoding WEBP at a lower quality (and optionally resizing) can cut file sizes significantly. This tool also strips metadata by design since canvas re-draw removes it.
Tips
- Try quality 65–85 for photos; higher for graphics with sharp edges.
- Use Fill/Crop to enforce exact dimensions for banners or covers.
- “Only keep output if it’s smaller” prevents enlarging files when not resizing.
FAQ
Do you upload or store my images?
No. Everything runs locally in your browser using HTML Canvas. Nothing leaves your device.
Lossless option?
This tool uses the browser’s WEBP encoder via canvas; most browsers provide lossy encoding with a quality setting. True lossless is not consistently exposed; for visually lossless, use quality 95–100.
