WebP Converter

It is a free browser tool that converts images between WebP, JPG and PNG. You add one or more images, choose a target format, WebP by default, and for WebP or JPG set the quality. When you click Convert Images, each file is redrawn at its original pixel size and saved in the new format with _converted added to its name. Transparency is kept in WebP and PNG output, and JPG output is placed on white.

WebP files are typically smaller than JPEGs at a similar visual quality, so portfolio and gallery pages load faster, which keeps visitors on the page, especially on phones and slower connections, and helps search performance. WebP also supports transparency, so logos and cut-outs can use it too. All current major browsers display WebP, which makes it a practical default for images on your own website.

Select several images in the file picker or drop them onto the upload area; you can keep adding more. Choose the target format and quality once, since the settings apply to the whole batch, then click Convert Images. The files are processed one after another, each marked Done or Error, and each downloads as a separate file. Your browser may ask once to allow multiple downloads. Clear All empties the list.

For displaying photos online, WebP usually gives smaller files than JPEG at the same visual quality, which matters most for large, high-resolution images. JPEG is still more widely accepted outside the browser: print labs, older software, some email clients and client downloads. Both are lossy 8-bit formats, so neither replaces your full-quality masters. A common approach is WebP for your website and JPEG for deliveries.

Convert at the end, after editing and resizing, when images are ready to publish. Resize to the dimensions your site displays first, because the converter keeps the original pixel size. Use it in the other direction when someone needs a classic format: turning WebP downloads into JPG or PNG for software that does not read WebP. Keep your masters in their original format so you can export again later.

Raise the quality slider, which runs from 10 to 100 and starts at 90, and convert again from your original file rather than from an already compressed copy. The converter does not resize, so pixelation usually comes from a small source image. If colors look muted, the original probably used a wide-gamut profile such as Adobe RGB, which is not carried over; convert to sRGB in your editor before converting.

Yes. WebP supports full transparency, including soft edges, and this converter keeps it: a transparent PNG converted to WebP stays transparent, usually in a much smaller file. PNG output keeps transparency as well. Only JPG output loses it, because JPEG has no transparency, so the converter places those images on a white background. For watermarks and logos on the web, WebP or PNG are the right choices.

WebP support was added to browsers over several years, so very old browser versions, and some older operating systems' built-in viewers, cannot display it. All current versions of the major browsers do. If part of your audience might use outdated software, or a platform rejects WebP, keep a JPG or PNG version as a fallback; this converter can create those as well.

Add the WebP file, choose JPG as the target format, set the quality high, such as 95 to 100, and convert. The JPG opens anywhere and print labs accept it. Converting cannot restore detail that was lost when the WebP was compressed, and transparent areas become white. For the best print, export a fresh JPG or TIFF from your original edit instead, if you still have it.

There is no fixed limit, and nothing is uploaded: every image is converted in your own browser. The practical limits are your device's memory and the largest image your browser can draw, which are generous on a modern computer. Very large photos take a little longer. For WebP output, use a browser that can write WebP, such as Chrome, Edge or Firefox; Safari saves PNG data instead.
