Convert JPG to WebP
Shrink JPGs into modern WebP files for faster-loading websites — without uploading anything.
Why convert JPG to WebP
WebP typically produces files 25–35% smaller than JPG at the same visual quality, which makes it the go-to format for web developers trying to speed up page loads and improve Core Web Vitals. If you’re putting images on a website, serving WebP is one of the easiest performance wins available.
This tool is built for that workflow: drop your JPGs, set a quality level, and get back compact WebP files — all locally, with no upload step that would slow down a bulk job.
Tune quality for size
The quality slider maps directly to WebP’s encoder. Around 80% is the sweet spot for web images — a large size saving with no visible loss. Drop lower for thumbnails, or raise it for hero images where detail counts.
Batch-friendly and private
Convert an entire image folder at once and download it as a ZIP, ready to drop into your project. Nothing is uploaded, so even large batches process quickly and your source images never leave your machine.

Frequently asked questions
Is WebP supported by all browsers?
Yes. Every current major browser — Chrome, Safari, Firefox and Edge — supports WebP, which is why it’s safe to use across modern websites.
How much smaller will my WebP files be?
It depends on the image, but a 25–35% reduction versus JPG at equivalent quality is typical, and often more for simple graphics.
Can I control the compression level?
Yes, use the quality slider. Lower values mean smaller files; higher values keep more detail.
