Frequently asked questions

How much smaller are WebP files than JPG?
WebP typically produces 25–34% smaller files than equivalent JPEGs at the same visual quality. For a typical 500 KB JPEG, you'd expect a WebP of roughly 330–375 KB with no perceptible quality difference.
Is my file uploaded to a server?
No. Conversion happens entirely in your browser. Your images never leave your device.
Does WebP work on all websites?
All modern browsers — Chrome, Firefox, Safari 14+, and Edge — support WebP. That covers over 96% of global users. For older browsers, use the HTML picture element with a JPEG fallback.
What quality setting should I use?
For photos on web pages, 80–85% is the sweet spot. For hero images and key product photos, use 85–92%. For thumbnails and background images, 65–75% produces tiny files.
Can I convert WebP back to JPG?
Yes. Use our WebP Converter tool to convert WebP images to JPG or PNG.
Can I batch convert multiple JPGs to WebP?
Yes. Drop multiple files and download all WebPs in a single click.
Is WebP lossless?
WebP supports both lossy and lossless modes. This converter uses lossy WebP (like JPEG) for maximum compression. For lossless output, convert to PNG instead.
Why use WebP instead of AVIF?
WebP has broader browser support (Safari 14+ vs AVIF's Safari 16.4+). AVIF offers better compression but requires fallbacks for more users. WebP is the safer choice for most websites today.
Will converting to WebP improve my Core Web Vitals?
Yes. Smaller image files directly improve LCP (Largest Contentful Paint). Google recommends WebP and AVIF as preferred web image formats.
Can I use this tool on mobile?
Yes. The tool works on any modern mobile browser — Chrome for Android, Safari on iPhone, and others.

Convert JPG images to Google's WebP format directly in your browser — no upload,

no signup, no software installation required. WebP typically produces 25–34% smaller

files than JPEG at the same visual quality, making it the recommended format for

web performance. All major browsers have supported WebP since 2020.

Use the quality slider to control the output: 80–85% delivers an excellent

size-to-quality ratio for web use. Higher settings (90%+) preserve more detail

for hero images and product photography. Lower settings (65–75%) produce the

smallest possible files for thumbnails and background images.

Batch conversion is fully supported — drop multiple JPG files at once and download

all WebPs in a single click. All processing runs client-side using the Canvas API;

your files never leave your device. Ideal for web developers optimising images for

faster page loads and better Core Web Vitals scores.
