Convert PNG images to WebP — typically 25–35% smaller at the same visual quality. Batch supported, ZIP download.
Everything runs in your browser — your images never leave your device.
PNG is the lossless standard — perfect quality, but heavy. WebP compresses the same picture ~25–35% smaller at visually identical quality, which makes pages load faster and saves storage. Every modern browser displays WebP, and most platforms (including social media and stores) accept it today.
This page re-encodes your PNGs as WebP inside your browser with the quality you choose. Use case: optimizing images for websites, reducing app asset sizes, or shrinking photo libraries.
Limitations: WebP with quality below ~100 is lossy — for pixel-perfect needs keep the PNG. Old software (pre-2020) may not open WebP. Chrome, Edge and Firefox encode WebP natively; older Safari versions may fail to export — in that case use the JPG / PNG / WebP Converter as fallback.
Conversion is 100% local, in your browser. Your images are never uploaded to any server and never stored.
For photos and complex images, typically 25–35% smaller at quality 85–90 with no visible difference. For flat logos and screenshots the saving can be even larger. Each converted file shows its new size so you can compare.
Yes — WebP supports full alpha transparency, so transparent PNG areas stay transparent in the WebP output.
90% is a safe default that looks identical to the original for almost every image. For maximum savings where slight softness is acceptable, try 80%.
Yes — select as many files as you want, click Convert All, then Download All to get everything in a single ZIP.
Usually yes: WebP files are smaller than JPG at the same quality, and smaller files mean faster pages and better SEO. Convert your PNGs here and JPGs with our WebP to JPG tool's reverse flow (the multi-format converter handles any direction).
Completely. The conversion happens in your browser with the HTML canvas — no file is ever uploaded or stored.
