Shrink PNG Assets for Faster Web Pages
PNG is dependable and lossless, but photographic screenshots, large illustrations, and interface exports can become unnecessarily heavy. Converting PNG to WebP applies modern compression that often cuts transfer size while keeping the image visually faithful. Use the quality control to choose a compact web delivery file or a higher-fidelity result, then preview and download without opening a desktop editor. For photographs that are already saved as JPG, use JPG to WebP instead.
Keep Transparent Backgrounds Intact
WebP supports an alpha channel, so transparent logos, stickers, icons, and product cutouts can remain transparent after conversion. The converter decodes the PNG and re-encodes its visible and transparent pixels directly in the browser. You get a smaller modern asset without adding an unwanted white or black rectangle behind the subject. If your source image still has a background, run it through Background Remover first to create a transparent cutout.
Convert Private Batches Without Uploading
Every PNG is processed locally by your browser, including quality adjustment, file renaming, and ZIP packaging. Client artwork, unreleased product images, and internal UI assets never leave your device. Add several files, apply one consistent WebP setting, and download the finished set without an account, a watermark, or a server queue.
How to Convert PNG to WebP in 3 Steps
Add your PNG files
Drop one PNG or a batch into the converter. The browser reads each file locally, so there is no upload delay and no image data is sent to us.
Choose WebP quality
Keep the balanced default or adjust quality to trade file size for fine detail. Transparent pixels remain available in the WebP result.
Download WebP images
Convert on your device, inspect the output, and download files separately or together in a ZIP archive with no watermark.
When Should You Convert PNG to WebP?
Optimize Transparent Website Graphics
Convert navigation icons, logos, badges, and transparent hero artwork to WebP so pages transfer fewer bytes without losing the see-through background.
Reduce Screenshot Download Size
Product screenshots and tutorial images can be large as PNG. WebP makes documentation, release notes, and landing pages lighter while retaining readable interface detail.
Prepare Product Cutouts in Bulk
Convert a folder of transparent catalog images with one quality setting, then download a named ZIP ready for a storefront or content system. Trim each cutout to a consistent frame with Image Cropper before you convert.
