Frequently Asked Questions
What is WEBP?
WEBP is a modern image format developed by Google that provides superior lossless and lossy compression
for images on the web, making pages load faster.
Why convert JPG to WEBP?
Converting JPG to WEBP can significantly reduce image file sizes (often by 30% or more) while
maintaining comparable visual quality, improving website speed and performance.
Will WEBP reduce image size?
Yes. WEBP uses advanced predictive coding and quantization, meaning it is more efficient at compression
than legacy JPEG, resulting in smaller file sizes.
Can I batch convert JPG files?
Absolutely. You can upload or drag and drop multiple JPG or JPEG files simultaneously into the queue to
convert them in a single batch.
Are my files uploaded?
No. Your files are processed entirely inside your local browser tab using client-side OffscreenCanvas
APIs. No data or image payload is ever uploaded to a remote server.
Can I resize before converting?
Yes, our options panel allows you to specify custom dimensions (width and height) and lock the aspect
ratio before triggering conversion.
