GUW WebP/JPG/PNG Converter

Need a fast, privacy-first way to convert WebP images to JPG/PNG (or the other way around)? The GUW WebP ⇄ JPG/PNG Converter handles single files and batch jobs directly in your browser — no uploads to a server and no installs. Drop a folder or multiple images, pick the target format and quality, and the converter will export web-friendly JPGs or lossless PNGs at scale. If you care about final file size or want to set exact pixel dimensions before conversion, use the Image Compressor & Resizer and the Image Resizer & Converter to trim, scale, and optimise images first. This is especially handy when preparing photos for the web, ecommerce listings, or email, where bandwidth and load times matter.

Working with newer formats like AVIF or HEIC? The converter integrates well with our other tools — convert AVIF to PNG/JPG with the AVIF → PNG/JPG tool or turn HEIC photos from iPhones into web-ready images using the HEIC → JPG/PNG page, then run the batch job here. Need branded output or subtle ownership marks before sharing? Add text or logo marks client-side using GUW Image Watermark to protect originals. And when you want an application icon or desktop shortcut from a converted image, create a Windows .ico file with Image to ICO. Together, these linked tools create a smooth, private workflow for converting, optimising, watermarking, and packaging images — all in-browser and ready for immediate use.
