JPG to WebP converter
WebP is a modern image format from Google that usually produces smaller files than JPEG at comparable quality — supported by all major browsers today. Convert JPG sources to WebP for CDN delivery, static sites, and apps. Processing is local and private.
How to convert JPG to WebP
1. Upload your JPEG file.
2. Set WebP quality (75–85 is common for photos).
3. Preview size savings if shown.
4. Download the .webp file.
WebP conversion examples
Static site hero
Replace a 450 KB hero.jpg with a 280 KB hero.webp — LCP improves without visible quality loss on retina displays.
E-commerce thumbnails
Thousands of product thumbs add up. WebP cuts bandwidth bills versus serving JPEG everywhere.
Progressive enhancement
Ship WebP with a JPG fallback via the picture element — convert masters once locally.
When to use WebP
• When you control hosting and want faster image delivery.
• When migrating from JPEG on a modern browser audience.
• When you need smaller files than JPG at similar quality.
When to stay on JPG
• When legacy email clients must display inline images — JPEG is safer.
• When a partner API accepts only .jpg extensions.
• When you need EXIF preserved for photography workflows — check metadata needs first.
Why WebP beats JPEG on the web
WebP uses predictive coding and optional alpha. For photos, its lossy mode often matches JPEG visually at lower bitrates. For graphics, lossless WebP can beat PNG — but this tool focuses on photo-like JPG sources.
CDN and cache headers
After conversion, serve WebP with correct Content-Type (image/webp) and long cache lifetimes. Version filenames when content changes to bust caches safely.
Quality mapping
WebP quality numbers do not equal JPEG percentages one-to-one. Compare visually: a WebP at 80 may match a JPEG at 85. Tune on a representative image before batch jobs.
Frequently asked questions
Is WebP lossy like JPEG?
WebP supports both lossy and lossless modes. JPG-to-WebP conversion here uses lossy settings comparable to JPEG quality sliders.
How much smaller is WebP?
Often 25–35% smaller at the same perceived quality, but results vary by image content.
Do all browsers support WebP?
All current major desktop and mobile browsers do. Very old Safari versions lacked support — rare today.
Can I convert WebP back to JPG?
Yes — use the WebP to JPG tool if a downstream system requires JPEG.
Are files uploaded?
No — conversion is entirely local.
Should I delete original JPGs?
Keep originals as masters until you verify WebP quality across key pages and devices.
