JPG to WebP Converter

Convert your JPG photos to WebP — the modern format that keeps the same visual quality for 25–35% less weight. Smaller images mean faster pages, better Core Web Vitals and happier visitors. The conversion happens entirely in your browser, with a quality slider for full control.

You can also paste from the clipboard (Ctrl+V)

Quality 82%80–85% WebP usually matches the look of a 90% JPG.

🔒 100% private: your files are processed by your own browser and never leave your device.

How it works

Drop your JPG files onto the box (click to browse or paste works too).
Set the WebP quality — 80–85% visually matches a quality-90 JPG at a much smaller size.
Press Convert. Each image is re-encoded to WebP locally on your device.
Download the results individually or all at once.

Features

Proven size savings

WebP's modern codec typically cuts 25–35% off an identical-looking JPG.

Quality slider

Dial in the exact trade-off; each row reports the final size so you can compare instantly.

Built for Core Web Vitals

Lighter hero images directly improve LCP — the metric Google ties to page experience.

Batch ready

Convert a whole photo set in one pass, with zero uploads.

Universal browser support

Every current browser renders WebP, from Chrome and Firefox to Safari and mobile.

Supported formats. Accepts .jpg/.jpeg. Outputs .webp (lossy, quality 50–100%). WebP also supports alpha if you later need it.

Common use cases

Migrating a blog's image library to WebP for faster loads.
Shrinking e-commerce product photos without visible quality loss.
Hitting green Core Web Vitals on image-heavy landing pages.
Reducing mobile data usage for your audience.

Limitations (honest ones)

Very old browsers (IE11, Safari ≤13) cannot display WebP. Encoding happens in your browser, so a few thousand huge photos will take a while — process large libraries in chunks. For lossless WebP from JPG, use the general Image Converter.
