JPG
JPG, also written JPEG, is the most common photo format. It uses lossy compression tuned for photographs and has no transparency. Most cameras, phones and websites still produce it, but its compression is decades old, so files are larger than they need to be.
WebP
WebP, created by Google, uses a more modern codec that makes photos about 25-35% smaller at the same visual quality. It also supports transparency and animation, and every current browser can display it.

Why convert JPG to WebP?
JPG has been the default photo format for decades, but its compression algorithm is now outdated. WebP, developed by Google, uses a more modern codec that produces files 25–35% smaller than JPG at the same visual quality, while also supporting transparency — something JPG can never do. Smaller images mean faster page loads, better Core Web Vitals scores, and improved SEO rankings.
How to use this tool
- 1. Upload your JPG file — click the upload area or drag and drop one or more .jpg/.jpeg files.
- 2. Adjust quality (optional) — use the quality slider; 75–85% is the ideal balance of size and clarity.
- 3. Convert — click "Convert to WebP" and the tool processes your files instantly in-browser.
- 4. Download — save your new WebP images individually or all at once.
Who is this tool for?
- Web developers optimizing image-heavy sites without a build pipeline.
- Bloggers and content creators shrinking photos before uploading to WordPress or a CMS.
- E-commerce store owners speeding up product photo galleries.
- Photographers exporting web-ready versions of their JPG originals.
Convert JPG to WebP Online for Free
In short: this tool converts JPG and JPEG photos to WebP directly in your browser. You choose the quality, convert many files at once, and nothing is uploaded. WebP photos are typically 25-35% smaller than the JPG they came from, so your website, shop or app loads faster.
How to convert JPG to WebP
- Drop your JPG images on the page, or click to choose them from your device.
- Set the quality with the slider. 80 is a good starting point for most photos.
- Click Convert and check the size saving shown for each file.
- Download your WebP images one by one, or use the download all button.
Why use WebP instead of JPG?
JPG has been the default photo format for decades, but its compression is now outdated. WebP uses a newer codec that keeps the same look in a smaller file. On a page with many photos, that adds up to seconds saved, lower hosting bandwidth and a better Largest Contentful Paint score. Google PageSpeed Insights even lists serving images in next-gen formats such as WebP as a recommendation.
What JPG to WebP is best for
- Website, blog and portfolio photos where page speed matters.
- Product photos for online stores such as Shopify and WooCommerce.
- Hero images and banners that are large and load first.
- Photo galleries and real estate or travel listings with many images.
- Email and social media pictures where small files send and load faster.
Choosing the right quality
The slider trades file size for detail. Around 80 is a balanced default that looks the same to most eyes. Use 90 or more for photos with fine texture or text, where flaws show easily. Go down to 60-75 for large background images where size matters most. A JPG is already compressed, so avoid very low settings, and keep your original JPG as the master copy because WebP at lower quality cannot restore what was removed.
Your photos stay on your device
Many converters upload your files to a server. This one does not. The conversion runs in your browser with your own processor, so there is no waiting for an upload and no copy of your photo anywhere else. That makes it a safe choice for family pictures, client shoots and unreleased work.
Need a different format?
Have graphics with a see-through background? Use PNG to WebP and keep the transparency. Need to open a WebP file in older software or an editor? Convert it back with WebP to JPG for the widest compatibility, or WebP to PNG to keep transparency. You can also turn a GIF into a still image with GIF to WebP, or convert iPhone photos with HEIC to JPG and HEIC to WebP. See every converter in Image Tools.
Good to know
- WebP is shown by Chrome, Edge, Firefox, Opera and Safari 14 or newer, on desktop and mobile.
- JPG has no transparency, so converted photos look the same as the original.
- PNG and BMP files are accepted as well as JPG and JPEG.
- Results depend on the photo: simple images shrink the most, very detailed ones less.
Perguntas Frequentes (FAQs)
How do I convert JPG to WebP?
Drop your JPG or JPEG files onto the page or click to browse, choose a quality level, and click Convert. When it finishes, download each WebP file. You can add several images at once.
How much smaller is WebP than JPG?
Google reports that WebP lossy images are about 25-34% smaller than comparable JPEG images at the same visual quality. The exact saving depends on the photo, and the tool shows the real before-and-after size for every file.
Will converting JPG to WebP reduce image quality?
At the default setting of 80 most people cannot see a difference. A JPG is already lossy, so converting again at a very low quality can add small artifacts. Keep the quality at 75 or higher for photos and keep your original JPG as the master copy.
What quality setting should I choose?
Start with 80, the default. It cuts file size a lot with no visible change for most photos. Use 90 or higher for images with fine detail or text, and 60 to 75 for large background photos where the smallest file matters most.
Does WebP support transparency like PNG?
Yes, the WebP format supports transparent backgrounds, but a JPG has none to carry over. Your converted photo will look the same as the original, and it is simply a smaller file.
Are my photos uploaded to a server?
No. The conversion runs entirely inside your browser using your own device. Your JPG files are never sent to DailyOnWeb or anyone else, so personal photos and client work stay private.
Can I convert many JPG files at once?
Yes. Select or drop several files together and they are converted in one go. Each result has its own download button. Very large batches depend on your device memory, so split them if your browser slows down.
Do all browsers and apps support WebP?
All current browsers display WebP: Chrome, Edge, Firefox, Opera and Safari 14 or newer, on desktop and mobile. Some older desktop software cannot open it, and for those cases you can convert WebP back to JPG.
Will switching to WebP improve my SEO?
It can help indirectly. Smaller images load faster, which improves Core Web Vitals such as Largest Contentful Paint, and Google PageSpeed Insights recommends next-gen formats like WebP. Faster pages are better for visitors and for search.
Can I use WebP images in WordPress, Shopify or my own site?
Yes. WordPress has supported WebP uploads since version 5.8, and Shopify, Wix, Squarespace and most website builders accept WebP too. In plain HTML, use the WebP file in an img tag as you would a JPG.
Can I convert PNG or BMP files too?
Yes. Besides JPG and JPEG, this tool accepts PNG and BMP images. For graphics with transparent backgrounds, the PNG to WebP converter has a switch to keep transparency.
Is it free? Is there a file limit or watermark?
It is free, with no sign-up and no watermark. There is no fixed file-size limit from us. The practical limit is the memory of your device.
