How to convert images to WebP in your browser

Step-by-step guide to turning PNG, JPG, GIF, and other images into smaller WebP files using File Utils locally in the browser, with quality tips and when to use WebP.

Why WebP?

WebP compresses photos and graphics more efficiently than many older formats, so you get smaller files with similar visual quality. That means faster page loads for sites and less storage when archiving screenshots or UI assets.

Before you start

  • Inputs the converter accepts typically include JPEG, PNG, WebP, GIF, BMP, TIFF, and SVG. SVG is rasterized (flattened to pixels) at the size you choose in the tool.
  • Everything runs in your browser; files are not uploaded to a server. Close the tab on shared machines after working with sensitive images.
  • If you need lossless transparency and broad tool support, PNG is still a good choice. WebP is ideal when you want smaller size and modern browsers.

Step-by-step

  1. Open the Image to WebP tool from the sidebar or the all tools hub.
  2. Drag and drop your images onto the drop zone, or click to browse and select multiple files.
  3. Wait for each file to appear in the queue with a progress or ready state. Large images or slow devices may take a few seconds.
  4. Adjust quality if the tool exposes a slider (higher = larger file, sharper detail).
  5. Use preview when available to compare before downloading.
  6. Click Download for each result, or use any download all control the page offers.

Tips

  • Photos usually compress well at moderate quality; UI graphics with hard edges may need higher quality to avoid banding.
  • After conversion, spot-check critical images in the context where they will be used (retina displays, dark mode, etc.).
