Convert JPG to WebP

WebP is an image format developed by Google that compresses photos more efficiently than JPG. Google reports WebP lossy images are typically 25–34% smaller than comparable JPG files at the same visual quality. Smaller images mean:

• Faster page loads, especially on phones and slow connections.
• Better Core Web Vitals. The largest image on a page often determines the Largest Contentful Paint time.
• Lower bandwidth and hosting costs for image-heavy sites and online stores.

All current versions of Chrome, Edge, Firefox and Safari display WebP, so for most websites it is a safe default today.

Drop your JPG files, set the quality and click Convert. The tool decodes each photo in your browser and encodes it as WebP; nothing is uploaded to a server. Several files download together as one ZIP with the original names and a .webp extension.

Picking the quality:

Quality	Typical use
90%	Product photos, portfolios, hero images
80%	General website and blog images
70%	Thumbnails, background images
60% and below	Very small previews; artifacts become visible

Converting a JPG that is already heavily compressed gives smaller savings, because some detail has already been thrown away. Start from the highest-quality original you have, such as the camera file or the export from your editor.

Format is only part of the story. A 4000 × 3000 photo shown in a 1200 px wide column wastes most of its pixels. For the best result:

1. Resize the image to the largest size it will actually be displayed at (for high-density screens, about twice the CSS width is plenty).
2. Convert to WebP at 75–85% quality.

Combining both steps often reduces a phone photo from several megabytes to 100–300 KB.

If you have a strict budget per image, for example 150 KB for product photos, the image compressor can output WebP and aim for an exact size in KB. It searches for the highest quality that fits, so you do not have to experiment by hand.

Most site builders and content management systems accept WebP uploads directly. If you write HTML by hand, a plain image tag works in all current browsers:

<img src="photo.webp" alt="Describe the photo" width="1200" height="800">

If you must support very old browsers, the <picture> element lets you list WebP first and a JPG fallback second. Always set width and height so the page does not jump while images load, and keep descriptive alt text for accessibility. Adding loading="lazy" to images further down the page delays them until the visitor scrolls near them, which speeds up the first view.

WebP is ideal for the web, but JPG is still the better choice when you are emailing photos to people who may use older software, sending images to a print service, or uploading to a form that lists only JPG and PNG. You can always go back with WebP to JPG.

For graphics with transparency, use PNG to WebP; WebP keeps the transparent areas while still shrinking the file.
