Convert PNG to WebP by dropping your file into Imgvert, waiting for the browser to process it, and downloading the finished WebP file. The converter is free, supports batch jobs, and is designed for private local processing: no upload, runs in your browser. That makes it useful for quick format fixes at work, school, or on a shared machine where you do not want image files copied to a remote server.
How to convert PNG to WebP
- Drop your PNG file on the upload area, or choose it from your device.
- Add more files if you want a batch conversion. The queue can process several images in one run.
- Conversion runs in your browser. The file is decoded and written as WebP locally, without an upload to Imgvert. The output keeps the source image's pixel dimensions.
- Download the WebP file, or download the full batch when every item is ready.
Why convert PNG to WebP
PNG is reliable, but it can be large for web pages, product images, and interface screenshots. WebP usually gives smaller files while keeping good visual quality, and it can support transparency. That makes PNG to WebP useful for websites, blogs, documentation, app assets, and image-heavy landing pages. If a tool does not accept WebP, keep a PNG fallback or use WebP to PNG.
For flat graphics with transparency, WebP can often reduce file size without giving up the transparent background. For photo sources, JPG to WebP follows the same local flow. For archival source files, keep the original PNG too.
Because the work happens in the browser, speed depends on your device and the size of the images. Small web graphics usually finish quickly. Large photos, scans, or animation frames can take longer, especially when you drop many files at once. If a batch feels too heavy, split it into smaller groups and download each group before starting the next one.

Limits and privacy
- Files are processed locally in this browser; they are not uploaded to Imgvert.
- This flow renders a still image and does not guarantee preservation of EXIF, ICC, HDR, depth, auxiliary images, animation, or multi-page data.
- Output quality and size depend on the browser encoder; animation is not preserved by this still-image flow.
