Drop in transparent UI elements, product cut-outs, or other PNG artwork and quickly encode them to WebP in
your browser. The experience mirrors our JPEG tool with the same privacy-friendly approach: Canvas/WebCodecs
when available and @squoosh/lib running in a dedicated worker for consistent output.
Drop PNGs into the uploader or browse your device. We support files up to 20 MB each.
Adjust WebP quality, keep transparency intact, and queue as many assets as you like.
Use the slider preview to validate results, then download in bulk or per file.
WebP maintains alpha transparency while delivering dramatically smaller file sizes compared with legacy PNG files. That means cleaner Core Web Vitals, faster UI rendering, and lighter image budgets for design systems.
This tool batches assets, respects your browser's sandbox, and keeps everything on-device. Quality controls let you strike the right balance between fidelity and size, and auto-download ensures a smooth production workflow.
