NanoImage is a free online JPG to WebP converter that also handles PNG to WebP, JPEG to WebP, GIF, SVG, and AVIF where your browser supports them. Convert images to WebP instantly with no signup, no upload limits, and batch processing for up to 20 files — all private in your browser.
WebP is designed for the web: smaller files, strong compression, and optional transparency. Converting JPG to WebP or PNG to WebP can speed up blogs, stores, and landing pages without visible quality loss at sensible quality settings.
Versus JPG, WebP often saves 25–35% on photos. Versus PNG, WebP can be much smaller for UI graphics while keeping transparency. Keep JPG or PNG when you need maximum compatibility (email, print, legacy CMS).
Skip WebP when the recipient cannot open it — some email clients, older desktop apps, print workflows, and legacy CMS uploads still expect JPG or PNG. Use JPG for maximum photo compatibility and PNG when you need lossless editing or guaranteed transparency in every viewer. Many teams serve WebP on the web but keep JPG/PNG originals for archives and client deliverables.
Upload your JPG or JPEG to NanoImage, set WebP quality (80–90% is a good default), and click Convert to WebP. Your file converts locally in the browser and downloads instantly — no account needed.
Yes. This free PNG to WebP converter runs entirely in your browser. Upload PNG files (including transparency), adjust quality, and download smaller WebP files for faster websites.
JPEG and JPG are the same for this tool. Upload your JPEG image, choose quality settings, and click Convert to WebP to export an optimized WebP file in seconds.
Yes, where your browser supports GIF input. Upload a GIF, convert to WebP, and often get a much smaller file for web pages while keeping good visual quality.
Upload your SVG when your browser can decode it. NanoImage exports WebP when image data is readable in the browser — use PNG or JPG sources if SVG is not supported in your session.
WebP is a modern alternative that often beats JPEG and PNG on file size, but JPEG and PNG remain universal for email, print, and older apps. Many sites serve WebP to supported browsers and keep JPG/PNG as fallbacks.
Yes. Upload up to 20 images at once, convert them all to WebP with the same settings, and download a ZIP. Ideal for optimizing product photos, blog images, or app assets in one pass.
