Why convert JPG to WebP?

WebP offers superior compression compared to JPG. You get the same visual quality at 25–34% smaller file sizes — ideal for web publishing, faster page loads, and saving storage space.

Does converting to WebP improve quality?

No. WebP cannot restore detail lost during JPG compression. However, at equivalent visual quality, WebP produces significantly smaller files.

Can I convert multiple JPG files at once?

Yes. Drop or select as many JPG files as you need. FileKit processes them all in your browser and lets you download individually or as a ZIP.

Is WebP supported everywhere?

All modern browsers and operating systems support WebP. It is the most widely supported modern image format on the web today.

Is there a file size limit?

Each file can be up to 50 MB. Since processing happens entirely in your browser, very large files may take a few extra seconds.

Will my images be uploaded to a server?

No. FileKit processes everything locally in your browser using the Canvas API. Your images stay on your device.

Can I adjust the output quality?

Yes. Use the quality slider to balance file size and visual sharpness. 80–85% is recommended for web use; 90%+ for maximum quality.

Which browsers support this tool?

All modern browsers — Chrome, Firefox, Safari, and Edge — support both JPG decoding and WebP encoding.

How JPG to WebP conversion works

WebP is a modern image format that uses advanced compression to deliver smaller files than JPG at the same visual quality. FileKit decodes each JPG using your browser's built-in image engine, then re-encodes the pixels as WebP. At equivalent quality settings, WebP files are typically 25–34% smaller than JPGs. The entire process runs locally — your photos never leave your device.
