WebP Converter

How to convert images to or from WebP

1. Choose the target format: WebP to make images smaller, or JPG/PNG to open WebP files in older apps.
2. Set the quality (for WebP and JPG). 80% is a good balance for websites.
3. Drop your images and download the converted files or a ZIP.

Why use WebP on your website?

Images are usually the heaviest part of a web page. Switching from JPG and PNG to WebP can cut total image weight by a third, which improves Largest Contentful Paint (LCP), a Core Web Vitals metric Google uses in rankings. Smaller images also mean lower bandwidth bills and faster pages on mobile networks.

Opening WebP files

Downloaded an image that ends in .webp and your editor won't open it? Convert it to PNG for lossless editing or JPG for sharing. Related tools: PNG to JPG, JPG to PNG and the Image Compressor.

WebP vs. JPG vs. PNG vs. AVIF

• JPG: universal support, good for photos, no transparency.
• PNG: lossless and transparent, but large for photos.
• WebP: lossy or lossless, supports transparency and animation, usually 25–35% smaller than JPG, supported by every modern browser.
• AVIF: even smaller than WebP in many cases, but slower to encode and not yet supported by every tool.

For most websites today WebP is the safest modern choice: the size savings are large and compatibility is no longer a concern.

Using WebP on WordPress, Shopify and other platforms

WordPress has accepted WebP uploads since version 5.8, Shopify serves WebP automatically to browsers that support it, and most site builders accept WebP files directly. If your platform still rejects WebP, convert to JPG for photos or PNG for graphics.

Opening WebP files on Windows and Mac

Recent versions of Windows Photos and macOS Preview open WebP files, but older software such as some versions of Microsoft Office or legacy photo editors do not. Converting to JPG or PNG here is the quickest fix and does not require installing anything.

Quality setting for WebP

WebP at 75–85% quality looks very close to a JPG at 90% while being noticeably smaller. Use 90% or higher for images with fine detail or text, and lower values for large background images where small artifacts will not be noticed.

Batch converting a whole website

For a site with many images, convert the largest ones first: hero images, banners and product photos usually account for most of the page weight. Add them all here, choose WebP at 80% quality and download the ZIP. Keep the same file names so it is easy to match them with the originals when uploading.
