Need a WEBP instead of a JPG? This free converter turns your JPG files into WEBP right in your browser — no uploads, no account, and no software to install. Everything below explains how it works, what changes when you convert, and how to get the best result.
How to convert JPG to WEBP
- Add your JPG files above — drag and drop, click to browse, or paste. Nothing is uploaded.
- Each file is decoded and re-encoded to WEBP on your device, right in the browser.
- Download each WEBP individually, or grab the whole batch as a single ZIP.
Why convert JPG to WEBP?
JPG is a good fit for sharing photos and web images, but it isn’t always the right choice when you need to share, upload, edit, or archive an image. Converting to WEBP gives you a file that’s better suited to those jobs.
What you gain with WEBP:
- Small file sizes
- Transparency support
- Great for websites
File sizes depend on the image and the settings you choose.

What is JPEG (.jpg)?
JPG (also written JPEG) is the universal photo format, standardized back in 1992. It is the default for digital cameras, the web, and virtually every device and app made in the last three decades.
JPEG uses discrete cosine transform (DCT) compression, dividing the image into 8×8 pixel blocks and discarding the fine detail your eye is least likely to miss. It is lossy and limited to 8 bits per channel, with every pixel opaque — no transparency.
What is WebP (.webp)?
WebP is a modern image format from Google, designed for the web. It offers both lossy and lossless modes, supports transparency and animation, and produces noticeably smaller files than JPG or PNG at similar quality.
WebP's lossy mode is based on VP8 intra-frame coding, while its lossless mode uses a dedicated predictor-based algorithm. Both modes support an alpha channel, and every current major browser can display WebP natively.
When WEBP is the right choice
WEBP is a strong pick for:
- Fast-loading website images
- Web graphics that need transparency
Quality and file size
WEBP is a lossy format, which keeps files small. Our converter defaults to high quality, and you can fine-tune it with the quality slider — 90–95% looks identical to most eyes while shrinking the file. File sizes depend on the image and the settings you choose. Need a specific file size instead? Try our compress-image tool.
Is it private?
Yes. Everything runs locally in your browser, so your JPG files are never intentionally sent to a server. Read more on our privacy page, or see whether converting images online is safe.
Frequently asked questions
Is this JPG to WEBP converter free?
Yes. It’s completely free with no signup, no watermarks, and no per-file limits beyond sensible batch caps that keep your browser responsive.
Are my JPG files uploaded to a server?
No. Conversion happens entirely in your browser using WebAssembly and your device’s own image tools, so your files are never intentionally sent to a server.
Does converting JPG to WEBP reduce quality?
WEBP is a compressed format, so you can trade a little quality for a smaller file using the quality slider. At 90–95% the difference is invisible for most images. Since JPG is already compressed, converting won’t restore lost detail, but it won’t noticeably degrade the image either.
Will converting to WEBP keep transparency?
WEBP supports transparency, but JPG images are fully opaque to begin with — so there’s nothing to lose, and your converted files stay opaque.
Can I convert multiple JPG files at once?
Yes. Add up to 50 files per batch, convert them together, and download them individually or as a single ZIP.
Does the JPG to WEBP converter work on a phone?
Yes. It runs in any modern browser — Chrome, Edge, Firefox, and Safari — on Windows, macOS, Android, and iPhone or iPad. Because it works on-device, you can convert straight from your phone’s photo library.
Is there a file size limit?
You can convert files up to 100 MB each. Because everything runs in your browser, very large files depend on your device’s available memory.
