WebP Converter
Convert any image to WebP for smaller file sizes on the web, or convert a WebP file to JPG or PNG for broader compatibility. Three conversion directions supported. Free, no signup, runs in your browser.
Upload any image or drag and drop
JPG, PNG, GIF, BMP
How to use this tool
- 1Choose the conversion direction at the top: 'Image to WebP' to convert JPG/PNG to WebP, 'WebP to JPG', or 'WebP to PNG'.
- 2Upload the source file by clicking the upload area or dragging the file onto it.
- 3Click the convert button. For WebP to JPG, the output uses 95% quality to minimise quality loss.
- 4Download the converted file using the download button.
Example
Choose 'Image to WebP', upload the JPG. The resulting WebP file is typically 30-50% smaller than the JPG - often around 600-800 KB. Serve WebP on the website and keep the JPG as the source file.
Choose 'WebP to JPG', upload the WebP file. Download the JPG. Word, PowerPoint, and most older applications accept JPG universally. Quality loss is minimal at the 95% output setting.
Common use cases
- Converting product images and blog photos to WebP before uploading to a website to reduce page load time
- Preparing images for a Next.js, React, or Gatsby project that serves WebP automatically
- Converting a WebP image downloaded from the web to JPG for use in Word, PowerPoint, or Photoshop
- Converting a WebP screenshot to PNG to share in an app that does not support WebP
Common mistakes
- Converting to WebP without checking platform support - most modern browsers and websites handle WebP, but some older apps, CMS plugins, and email clients do not. Test before replacing all images.
- Expecting lossless quality when converting WebP to JPG - JPG is a lossy format. Even at 95% quality, there is a small reduction in sharpness compared to the original source.
- Using WebP for images that need to be shared widely offline - WebP is not as universally supported as JPG in non-browser contexts. For emails and documents, convert to JPG first.
- Converting repeatedly between lossy formats - each JPG-WebP-JPG conversion round trips lose quality. Always start from the highest quality source you have.
Frequently asked questions
What is WebP?
WebP is a modern image format developed by Google. It achieves 25-35% smaller file sizes than JPG at equivalent visual quality, and supports transparency like PNG. It is the recommended format for web images in most performance guidelines.
Is WebP supported everywhere?
All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. However, older applications, some email clients, and certain desktop software do not. For maximum compatibility in non-web contexts, use JPG or PNG.
Does WebP support transparency?
Yes. WebP supports both lossy and lossless transparency, similar to PNG. When converting a PNG with a transparent background to WebP, the transparency is preserved.
Is converting from WebP to JPG lossy?
Yes. JPG is a lossy format, so some quality is lost in any conversion to JPG. The converter uses 95% quality to minimise this. For the best results, always start from the original source file rather than re-converting.
How much smaller is WebP than JPG or PNG?
Google's tests show WebP is 25-34% smaller than JPG at equivalent quality for lossy images, and 26% smaller than PNG for lossless images. Real-world results vary by image content - photographs compress well, while flat graphics see smaller gains.
Should I use WebP or JPG for my website?
WebP is the better choice for web use in 2024 and beyond - smaller files mean faster load times and better Core Web Vitals scores. Use WebP as the primary format and serve JPG as a fallback for older browsers if needed.
Is my image uploaded to a server?
No. All conversion happens in your browser using the Canvas API. Your image never leaves your device.
