What is WebP and why should you convert to it?

WebP is a modern image format developed by Google that provides superior compression compared to JPEG. A WebP file is typically 25–50% smaller than an equivalent JPEG at the same visual quality — making it ideal for websites, apps, and anywhere you need fast-loading images.

Unlike JPEG, WebP supports both lossy and lossless compression, as well as transparency (like PNG). Today, every major browser and operating system supports WebP, making it the go-to format for web performance in 2026.

How TinyPixels converts JPG to WebP

Most online JPG-to-WebP tools require you to upload your images to a cloud server, wait for processing, then download the results. TinyPixels eliminates every one of those steps. Our native engine runs directly on your CPU — on Apple Silicon, this means hardware-accelerated conversion that finishes entire photo libraries in seconds.

Simply drag a folder of JPEGs into TinyPixels, choose WebP as your output format, set your quality level, and hit Convert. Done. No account. No internet. No waiting.

Bulk conversion built in

TinyPixels uses all available CPU cores to convert multiple images simultaneously. Whether you have 10 or 10,000 JPEGs, the conversion time scales efficiently.

Frequently asked questions

How do I convert JPG to WebP on Mac?

With TinyPixels, simply drag your JPG files into the app, select WebP as the output format, and click Convert. Everything runs locally — no internet connection needed. You can also drag an entire folder to convert thousands of JPEGs at once.

What is the best JPG to WebP converter?

The best converter depends on your needs. For occasional online use, Squoosh works well. For bulk conversion without uploading files — especially important for sensitive or client images — TinyPixels is the best option for Mac and Windows users.

Can I convert JPG to WebP without losing quality?

Yes. TinyPixels offers adjustable quality settings for WebP output. Set quality to 80–90% for visually lossless results at 50–70% smaller file sizes compared to the original JPEG. You can also use lossless WebP mode to preserve every pixel.

Is there a bulk JPG to WebP converter?

TinyPixels is designed for bulk conversion from the ground up. Drop an entire folder of thousands of JPEGs and it will convert them all to WebP using all available CPU cores simultaneously — in seconds, entirely offline.
