PNG to WebP Converter

Add your PNGs — drag and drop them or click Select Files. You can add several at once.

Choose the mode — set the Quality slider (80 is a good default) for a smaller lossy file, or tick "Lossless Mode" to keep every pixel exactly while still shrinking the file.

Download — click "Download ZIP" to save the whole batch, or grab files individually. Use "Clear All" to start over. ```

Yes. WebP supports an alpha channel, so a PNG with a transparent background stays transparent after conversion — in both lossy and lossless modes. This is the main advantage of WebP over JPG for graphics and logos: you get a much smaller file without losing the see-through areas you need. Nothing about the transparency is flattened or filled.

Lossy mode (the default, around quality 80) discards a little data to make the file as small as possible, with a difference that's usually invisible. Lossless Mode keeps every pixel exactly, which matters for crisp logos, text, or flat-colour graphics. Lossy gives the smallest files; lossless gives perfect fidelity — and even lossless WebP is typically smaller than the original PNG.

Almost always, yes. Lossy WebP can be a small fraction of a PNG's size, and even lossless WebP is usually meaningfully smaller, because its compression is more modern and efficient than PNG's. That's why WebP is recommended for graphics on websites — you keep the quality and transparency of PNG while loading far less data.

No. The converter runs entirely in your browser, so your PNGs are processed on your own device and never sent anywhere. Nothing is stored once you close the tab. That keeps personal or proprietary graphics private, and conversion is fast because there's no upload — the only limit is your device's speed.

For lossy conversion, 80 is a sensible default — small files with no visible loss for most graphics and photos. Drop lower for backgrounds or non-critical images where size matters most; raise it toward 90 for images with fine detail or gradients. If exact fidelity is essential, skip the slider and use Lossless Mode instead.

Yes. Drag in a whole batch of PNGs and the tool converts them all locally. When they're ready, click "Download ZIP" to save the entire set in one folder, or download files individually. "Clear All" resets the workspace for a new batch. There's no cap beyond your device's memory, so it handles folders of graphics easily.

Use Lossless Mode when the image must stay pixel-perfect — logos with sharp edges, icons, screenshots, diagrams, or any graphic with text and flat colours. In those cases even slight lossy artefacts can look bad. For photographs or large background images, lossy at quality 80 is usually the better trade-off because the file is much smaller and the loss is invisible.

Yes. Every major modern browser — Chrome, Firefox, Edge, and Safari — supports WebP, so you can use it across the web with confidence. Only very old browsers lack support, in which case a PNG or JPG fallback covers them. For today's devices and browsers, WebP displays everywhere.

In lossy mode there's a small, usually invisible loss in exchange for a much smaller file. In Lossless Mode there's no quality loss at all — the pixels are preserved exactly, just stored more efficiently than PNG. So you choose: maximum size savings with lossy, or perfect fidelity with lossless, both keeping transparency.

Yes. It runs in your phone's browser with nothing to install, so you can convert PNGs to WebP directly on Android or iOS. Small batches convert quickly; very large or high-resolution sets use more memory and are smoother on a laptop, but everyday conversions work fine on a modern phone.

No — this tool focuses on converting PNG to WebP with quality and lossless controls; it doesn't change pixel dimensions. If you want to resize, use the Image Resizer first to set the dimensions, then convert to WebP here. Combining a smaller size with the WebP format gives the leanest possible web images.

No. There's nothing to download or install and no account to create. The converter runs in any modern web browser, on any operating system, so you don't need a desktop image editor or a separate app. Just open the page, add your PNG files, choose your mode, and convert.
