or browse files from your device

Supports .jpg, .jpeg, .png (Unlimited Batch Processing)

100% Private & Local

Your browser reads the chosen JPG or PNG, paints it onto a canvas and creates the WebP output on your device. The source pictures stay in the active browser session; this page does not transfer them to an external image-conversion endpoint.

Batch Conversion

Convert dozens of images simultaneously. Preview savings per image and export everything in one organized ZIP file.

Boost SEO & Speed

WebP can reduce image file size compared with JPEG at similar visual quality. Smaller image assets can lower bandwidth use and support faster page loading.

Convert JPG to WebP Online Without Installing Software

Use this free JPG to WebP converter to change JPEG photos into the WebP image format directly in your browser. WebP is designed for the web and supports lossy and lossless compression, as well as transparency. It is useful for website owners, designers, bloggers, developers, and anyone preparing images for faster online delivery.

A WebP export may weigh less than the starting JPEG, but the result varies with image detail, pixel dimensions and the selected encoding quality. Replacing oversized photographs with appropriately sized assets can reduce page payloads. Page speed still depends on the rest of the site, including scripts, fonts, hosting and caching.

How to Convert JPG, JPEG, or PNG to WebP

  1. Select your images: Drag and drop JPG, JPEG, or PNG files into the converter, or use the browse option.
  2. Choose WebP quality: Adjust the quality slider to balance image appearance and file size.
  3. Resize if required: Keep the original dimensions, set a maximum dimension of 1920px or 1280px, or scale the image to 50%.
  4. Convert and review: The browser processes each image and displays its output dimensions and file size.
  5. Download your WebP files: Save images one by one or use the ZIP download for the whole batch.

When Should You Use WebP Instead of JPG?

WebP is a practical choice for website photos, blog images, product pictures, and other web graphics when your publishing platform and audience browsers support it. Keep an original copy of important photographs before converting them, especially when you may need to edit or export them again later. For images where exact pixel preservation is essential, compare the available lossless option and inspect the result before publishing.

Convert Images Privately in Your Browser

WebP files are produced with the Canvas features built into your browser. Image decoding and encoding take place on the computer or phone running this page. Large dimensions and multi-file batches can take longer, particularly on devices with limited memory.

How the Browser Encodes WebP Images

For each source picture, the browser creates a bitmap, paints it at the requested width and height, then exports the canvas using its WebP encoder. The quality control influences lossy compression where the browser supports it. The result remains a pixel-based image; it is not converted into editable vector paths.

Optimize or Reuse Your New WebP Images

After creating WebP files, you can reduce their dimensions or file weight further, or convert a copy back to JPG when a destination only accepts JPEG images.
