JPG to WEBP Converter
WEBP images are 25–35% smaller than JPG at the same visual quality — perfect for websites and sharing. No quality loss you can actually see.
Why convert JPG to WEBP?
WebP is the modern web image format, developed by Google to replace JPG with smaller files at the same visual quality. A typical photo converted from JPG to WebP shrinks by about 25–35% with no visible difference. For websites and online photo galleries, that adds up to dramatically faster page loads and lower bandwidth costs.
Every modern browser (Chrome, Firefox, Safari, Edge) supports WebP natively, and Google considers it the recommended format for the web in 2026. If you're publishing photos online, WebP should be your default.
The main reason to still use JPG is compatibility with platforms and software that haven't updated — some printing services, email clients, and older photo editors still don't accept WebP.
About JPG
JPG is the long-standing photo format from 1992. It uses lossy compression optimized for photographic content and is supported by every device, browser, and platform.
About WEBP
WebP is Google's image format, released in 2010 and now widely adopted across the web. It supports both lossy and lossless compression, transparency, and animation. Lossy WebP files are typically 25–35% smaller than equivalent JPGs at the same visual quality.
Quality and file size
At standard WebP quality settings, the output is visually identical to the source JPG but significantly smaller. WebP's compression is more efficient than JPG's, so you get the same visual quality with fewer bytes. There's a small re-encoding loss but it's invisible on photographic content.
Measured on one 12.5 MP phone photo (3072 × 4080, large smooth-gradient sky): 2,443 KB as JPG, 691 KB as WebP at quality 80 — 72% smaller, with no difference visible at normal viewing size. Pushed to quality 95, where it measures near-identical to the source, it still came out around 20% smaller.

Filesmith runs entirely in your browser using WebAssembly. Files are never uploaded to any server — conversion happens locally on your device, instantly and privately.
When WebP is the right target
- Website images. Smaller files mean faster pages, which affects both ranking and how the page feels to use.
- Sharing photos. Same picture, a fraction of the size, no visible difference.
- Storage. Useful when space is tight and you don't need an editing master.
- Graphics with transparency, where WebP replaces PNG at a much smaller size — see PNG to WebP.
Support is no longer the concern it was: every current browser handles WebP, including Safari since 2020. Older software is a different matter — some desktop editors, older phones and a few print workflows still reject it.
Print. If artwork is going to a printer, send a high-quality JPG, a PNG, or the original — WebP was designed for screens and print workflows frequently won't take it. The same goes for anything you'll hand to a client who has to open it in whatever they happen to own.
