Convert JPG to WebP Online

Images are often the heaviest part of a web page. Product galleries, blog headers and portfolio photos are usually JPG, and for many of them a lossy WebP at similar visual quality is a smaller file. Smaller images download faster, especially on mobile connections.

WebP is displayed by all current major browsers, which makes it a practical format for websites, blogs and online stores. It is not always smaller than JPG, though, so this converter shows the original and converted sizes side by side. You can see the real difference for your image instead of relying on a general rule.

This page is set up to output WebP. Upload a JPG, adjust the quality, and download a .webp file. If you already have WebP files that need shrinking, use the WebP compressor.

Compare sizes, not just settings

WebP and JPG quality numbers are not directly comparable. A JPG saved at 90% and a WebP at 90% will not look or weigh the same. Instead of matching numbers, look at the result: compare the file sizes shown, zoom in on skin, foliage, fabric and other fine textures, and lower the quality only while the image still looks right.

If a JPG was already compressed heavily, the WebP may barely be smaller. In that case there is little reason to switch, and the original JPG may be the better file to keep. Setting a target size works too, but the tool may reduce dimensions if quality alone cannot reach it, so check that the image is still large enough for your layout.

Convert once, from the best source

Both JPG and lossy WebP discard detail. Converting cannot bring back what the JPG already lost, and every extra lossy save removes a little more. Convert from the highest-quality JPG you have, avoid converting the same image back and forth, and keep the original so you can re-export later with different settings.

Using WebP on your site

Many content management systems and store platforms accept WebP uploads, but support depends on the platform, its version and any plugins, so check before replacing a whole library. If you hand-code pages, the HTML <picture> element lets you offer WebP with a JPG fallback.

When to keep JPG

• Email attachments and files you share with people using unknown software.
• Printing, since some print services only accept JPG or PNG.
• Upload forms that list JPG as the accepted format.
• Older desktop software that cannot open WebP.

For those cases, make the JPG smaller with the JPG compressor. If you receive a WebP that will not open somewhere, the WebP to JPG converter turns it back into a JPG. Transparent PNG graphics are better handled by the PNG to WebP converter.

Where conversion happens

Current Chrome, Edge and Firefox can encode WebP, so the image is converted on your device. In browsers that cannot, the tool sends the image to our server, converts it in memory and discards it. Either way, EXIF metadata such as GPS location is removed.
