Free WebP Converter
Convert images to WebP with guaranteed lossless quality. 97% browser support, zero quality loss.
How to Convert an Image to WebP
Upload Your Image
Drag and drop or click to browse. Supports JPEG, PNG, GIF, and HEIC input formats. Your image is uploaded securely over HTTPS and processed on our servers. Files are automatically deleted after download.
Optionally Edit
Before converting, you can resize, crop, rotate, or adjust DPI -- all tools are available on this page. Skip this step if you just want to convert the format without any changes to dimensions or composition.
Convert to WebP
Click convert and download your WebP image. Expect files 25-34% smaller than JPEG at the same quality. Every conversion is validated with PSNR/SSIM metrics to guarantee zero quality loss.
Frequently Asked Questions
WebP is a modern image format developed by Google in 2010 that provides superior compression for web images. It supports both lossy compression (like JPEG but 25-34% smaller) and lossless compression (like PNG but 26% smaller). WebP also supports transparency (alpha channel) and animation (replacing GIF with much better quality and smaller files). With 97% global browser support, WebP is the safest and most practical next-generation image format for web use today.
WebP enjoys approximately 97% global browser support, making it production-ready for virtually all websites. Every major browser supports it: Chrome (since 2014), Firefox (since version 65), Edge, Safari (since version 14 on macOS Big Sur and iOS 14), Opera, Samsung Internet, UC Browser, and all other Chromium-based browsers. The only browsers without support are Internet Explorer and very old Safari versions, which together represent less than 3% of global traffic and are declining rapidly.
SharpWebP uses lossless WebP encoding by default, which preserves every single pixel with mathematically perfect fidelity. The file gets smaller, but the image data is identical -- verified by automated PSNR (peak signal-to-noise ratio, targeting infinity for lossless) and SSIM (structural similarity, targeting 1.0) checks on every conversion. You literally cannot tell the difference because there is no difference. The smaller file size comes purely from WebP's more efficient compression algorithm, not from discarding image data.
WebP files are typically 25-34% smaller than equivalent JPEG files at the same perceptual quality, according to Google's own studies and our internal testing. For lossless images (compared to PNG), WebP achieves approximately 26% smaller files. The savings vary by image content: photographs with smooth color gradients see the largest reductions (sometimes over 40%), while images with sharp edges, text, or fine geometric detail see moderate savings (20-25%). SharpWebP displays the exact file size reduction after every conversion.
Yes, completely free with no catches. SharpWebP's WebP converter requires no account, no signup, and applies no watermarks or quality restrictions. Free users can convert up to 5 images per day. WebP is the core format that SharpWebP is built around, so it is always available as an output format on every plan. Paid plans (starting at 499 INR/month) unlock batch conversion for processing dozens of images at once, higher daily limits, and additional output formats including AVIF and JPEG XL.
