Image to WebP Converter
Convert PNG, JPG, GIF and BMP images to WebP and cut your page weight. Everything runs in your browser, so your images are never uploaded anywhere.
PNG, JPG, GIF, BMP or AVIF. Up to 30 images at once.
Your images never leave your device. This converter uses your browser's own canvas encoder, so nothing is uploaded to a server. It keeps your files private and means large batches convert as fast as your machine allows.
What is a WebP file?
WebP is an image format built by Google that supports both lossy and lossless compression, transparency and animation. It produces files that are meaningfully smaller than JPEG, PNG and GIF at the same visual quality, which is why it is now the default choice for images on the web. Every current browser supports it.
Is WebP better than PNG or JPG?
For the web, yes in most cases. WebP is typically 25 to 35 percent smaller than a comparable JPEG and can be 70 to 90 percent smaller than a PNG, while keeping transparency support that JPEG does not have. Smaller images mean a faster Largest Contentful Paint, which is one of the Core Web Vitals Google measures. Keep PNG only when you need pixel-exact lossless output, such as for logos you will edit again later.
How do I convert images to WebP?
Drag your images into the box above, or click browse to pick them. Set the quality (80 to 90 suits most photos) and optionally cap the width, then press convert. You will see exactly how much each file shrank, and you can save them one by one or all at once.
Does WebP hurt SEO?
No, it helps. Google both created the format and rewards the faster loading it enables. Serving WebP reduces page weight, improves Core Web Vitals and lets Google index your images normally. Just remember to keep descriptive file names and alt text after converting.
What quality setting should I use?
Start at 85. Photographs usually look identical to the original between 80 and 90 while saving a large amount of weight. Drop to 70 for background or decorative images where fine detail does not matter. Go above 95 only when the image contains sharp text or fine lines. If your image is far wider than it is displayed, resizing it will save more than any quality change.
