Convert JPG to WebP for faster-loading web pages
This JPG to WebP converter re-encodes your JPG and JPEG photos as WebP, the image format Google designed for the web. Add a batch of images, pick a quality and download WebP files that are typically noticeably lighter than the originals — useful for site owners, bloggers, online sellers and anyone fighting a slow page or a hosting quota. Everything runs locally in your browser; no photo is uploaded.
Every current major browser displays WebP, and page-speed audits such as Google’s Lighthouse have long flagged JPGs that could be served in a more modern format. Smaller images mean faster pages, lower bandwidth costs and a quicker Largest Contentful Paint, which matters most on mobile connections.
How to use the JPG to WebP Converter
- Drop your JPG files onto the upload area or click it to choose them; Ctrl+V pastes a copied image.
- Move the Quality slider. 75–85 is the usual range for photos on websites.
- Leave Camera data (EXIF) on Remove for web use — it trims a few kilobytes and keeps locations private.
- Compare the before and after sizes in the list, and check the preview by switching between Converted and Original.
- Download the WebP files one by one, or press Download all for a ZIP.
JPG to WebP Converter features
Real WebP encoding
Uses the browser’s built-in WebP encoder in Chrome, Edge and Firefox. Safari can show WebP but not create it; there the tool tells you and saves a PNG instead of failing silently.
Quality slider with live sizes
Every image re-encodes as you adjust the quality, so you can find the smallest file that still looks right.
EXIF in WebP
Strip camera data or keep it. Kept EXIF goes into a standard WebP EXIF chunk, with the orientation reset because the pixels are already upright.
Upright photos
Sideways phone pictures are rotated according to their EXIF orientation before encoding.
Batch ZIP download
Convert an entire image folder for a website in one go and download a single archive.
How WebP makes photos smaller than JPG
Google announced WebP in September 2010. Its lossy mode is built on the intra-frame coding of the VP8 video codec: it predicts each block of pixels from neighbouring pixels that have already been decoded and stores only the difference, transforms that difference in small 4×4 blocks, and packs the result with an arithmetic coder, which squeezes out more redundancy than the Huffman coding used by most JPGs. Google’s own comparison found lossy WebP files 25–34% smaller than JPGs of equivalent quality, measured with the SSIM index.
Your results will vary from picture to picture, which is why the converter shows the real size of every file. Re-encoding an existing JPG also means compressing it a second time, so start from the largest, best-quality JPG you have and avoid very low quality settings — WebP artefacts look like blurring and smearing rather than JPG’s blockiness.
Using WebP on your website
- Every current version of Chrome, Edge, Firefox, Opera and Safari displays WebP. Safari added support in version 14 (2020) on iOS 14 and macOS Big Sur, so only very old Apple devices miss out.
- To cover those, serve WebP with a JPG fallback using the HTML
<picture>element: a<source type="image/webp">line followed by the normal<img>tag. - WebP images can be at most 16,383 × 16,383 pixels. The converter warns you if a photo is larger; shrink it first with the image resizer.
- Resize before converting: a 4,000-pixel-wide photo shown at 1,200 pixels wastes most of its bytes, whatever the format.
- For the very smallest files, try JPG to AVIF. WebP encodes far faster and works in slightly more places.

JPG to WebP Converter FAQ
How do I convert JPG to WebP?
Add your JPG files, set the quality (around 80 for website photos) and download the WebP versions individually or as a ZIP. The conversion happens in your browser, so even large batches don’t need uploading.
Is WebP better than JPG?
For websites, usually yes: WebP produces smaller files at similar visual quality and also supports transparency and animation. JPG still wins on compatibility with older software, cameras and print services.
Why does Safari give me a PNG instead of a WebP?
Safari can display WebP images, but its canvas cannot encode them. When that happens the converter tells you and saves a PNG rather than failing. Open this page in Chrome, Edge or Firefox to create WebP files.
Will converting JPG to WebP lose quality?
A little, because the photo is compressed again. At quality 80–90 the difference is very hard to see. Always convert from the original JPG rather than from a copy that has been saved several times.
Can WebP files keep EXIF data?
Yes. Choose Keep under Camera data and the EXIF block is stored in the WebP file. For public websites Remove is usually better: slightly smaller files and no hidden GPS location.
What quality should I use for WebP?
Around 75–85 suits most photos on web pages. In Chrome and Edge, quality 100 switches to lossless WebP, which is much larger and only worth it for graphics.
