Free Online WEBP Image Converter – Convert Any Image to WEBP Instantly

Yes! Our online WEBP converter is completely free to use with no limits on the number of conversions, file size, or image quality. We do not offer paid plans or premium features – all functionality is available to every user at no cost. We generate revenue through minimal, non-intrusive affiliate partnerships, which allows us to keep the tool free for everyone.

We support a wide range of input formats including JPG, JPEG, PNG, GIF, BMP, TIFF, ICO, and more. If you have an image file that isn't converting, please check that it's one of our supported formats – if not, contact our support team for assistance. We regularly update our format support based on user requests and industry standards to ensure maximum compatibility.

Lossless WEBP compression preserves all original image data, resulting in perfect quality but moderate file size reduction (typically 25-30% smaller than PNG). Lossy compression removes non-essential data to achieve much larger size reductions (up to 80% smaller than JPG), with quality that's visually indistinguishable from the original for most use cases. Our converter lets you choose which type to use, or auto-selects based on your input image.

Yes! WEBP supports alpha channel transparency, and our converter preserves full transparency when converting from PNG, GIF, or other transparent formats. This makes WEBP an excellent replacement for PNG files, offering the same transparency with significantly smaller file sizes – perfect for logos, icons, and graphics used on websites and apps.

WEBP is supported by all modern browsers including Chrome, Firefox, Edge, Safari 14+, and Opera. For older browsers, we recommend providing a JPG/PNG fallback – though over 95% of global web traffic now uses browsers that support WEBP. Our converter also produces WEBP files compatible with all major operating systems (Windows, Mac, iOS, Android, Linux).

We support file sizes up to 50MB per image. If you need to convert larger files, we recommend compressing the image first using an online image compressor before uploading to our WEBP converter. Our compression tool (available on the same platform) can reduce file size without losing quality, making it easier to convert large images quickly and efficiently.

Yes! Our tool supports batch conversion, allowing you to upload and convert up to 20 images at a time. This saves you time if you have multiple files to convert – simply select all your images in the upload dialog, and we'll process them all at once. You can download each converted WEBP individually or as a single ZIP file for convenience, perfect for bulk website or app optimization.

Our lossless WEBP option preserves 100% of the original image quality, while our lossy option uses advanced compression algorithms that maintain visual quality while drastically reducing file size. Most users cannot distinguish between lossy WEBP files and the original JPG/PNG, but you can adjust the quality slider to prioritize quality over file size if needed. We recommend the default settings for the best balance of size and quality.

Most image conversions take between 1-5 seconds, depending on the file size and your internet connection. Small files (under 1MB) convert in under a second, while larger files (up to 50MB) may take a few extra seconds. We use cloud-based processing to ensure the fastest possible conversion times, even during high-traffic periods, so you never have to wait long for your optimized WEBP files.

Absolutely. All file uploads are encrypted using SSL/TLS technology, and we automatically delete all uploaded files and converted WEBP files from our servers after 24 hours. We never store your files long-term or share them with any third parties – your privacy is our top priority. Our security protocols are regularly audited by independent third-party firms to ensure compliance with global data protection standards.
