About the JPG to WebP
Switching site photos from JPG to WebP is the single biggest image performance win available — same look, meaningfully less bandwidth. Drop up to 10 JPGs and get WebP back instantly, with no upload touching a server.
How it works
The browser's WebP encoder re-encodes your decoded JPG pixels at the quality you pick. WebP's modern compression usually lands well below JPEG's file size at matching visual quality, and because the tool works locally, converting a 10-photo batch takes seconds rather than an upload round-trip.
How to use it
Drop up to 10 .jpg files, set the WebP quality — 85 is a strong default for photos — and convert. Results show the size delta per file; download individually or as one ZIP.
Supported formats & limitations
Accepts .jpg/.jpeg up to 30MB per file, 10 per batch; output is .webp. A single re-encode at high quality is visually safe, but stacking conversions across formats repeatedly compounds softness — convert from the original where possible.
Common use cases
The single biggest image performance win for most websites: converting blog photos, store product shots and hero images from JPG to WebP directly improves load time and Lighthouse scores without changing how pages look.
Frequently asked questions
Where are my images processed?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
What kind of image files work with this tool?
JPG inputs are supported, up to 30 MB per file. For exotic formats, convert them first with one of the converter tools, then come back.
What are the size and batch limits?
You can queue 10 files per run, each up to 30 MB. Results download individually or bundled as a single ZIP.
Can I fine-tune the result before downloading?
Yes — settings include WebP quality. Each run regenerates the preview, so you can compare options before downloading.
