PNG to WebP Converter — Free WebP Converter Online (JPG, JPEG)

PNG to WebP Converter — Free WebP Converter Online (JPG, JPEG). Convert batches of still JPG, PNG and WebP images to WebP locally. Control quality and maximum width, compare results and download images or a ZIP.

Use this image to WebP converter for up to 10 still JPEG, PNG or WebP images. Set quality from 1–100 and a maximum width from 1–8,192 pixels.

The default width preserves supported source dimensions; smaller widths resize proportionally without enlarging images. Outputs use the browser’s lossy WebP encoder, so quality 100 does not guarantee lossless results.

Each input and output is limited to 20 MiB. Source images must fit 24 megapixels and 8,192 pixels per edge. Selected inputs and completed outputs each have a separate 50 MiB total limit. Processing stops after 30 seconds per file.

Cancel keeps completed results and lets you retry unfinished files. GIF, SVG, AVIF, HEIC, animated PNG and animated WebP are unsupported. Every successful output is WebP, even if it is larger than the original.

An unsupported encoder produces an error instead of a substitute PNG. WebP can preserve transparency; the browser decoder applies orientation. Re-encoding does not copy source EXIF, and colors or profiles may change.

Compare the fit-sized previews and inspect important downloads in an image viewer. Images are processed locally without upload or browser storage; ads make separate network requests. For other output formats use Image Compressor.

Frequently asked questions

How do I convert several images to WebP?

Choose up to 10 still JPG, PNG or WebP files, set quality and maximum width, then convert. Review actual dimensions and file size before downloading WebP images or a ZIP. Images stay on this device; ads make separate network requests.

Is quality 100 lossless?

Quality controls lossy WebP encoding. Higher values can increase file size; 100 does not guarantee lossless output.

Will conversion always make images smaller?

No. WebP output can be larger, especially for small or already optimized files. The requested WebP output is retained and the actual size difference is shown. Lower quality or maximum width and compare again.

Can I convert animated images or HEIC?

No. Only still JPEG, PNG and WebP are supported. Animated PNG and WebP are rejected to avoid losing frames; GIF, SVG, AVIF and HEIC require another converter.

What happens to transparency, orientation and metadata?

WebP supports transparency. The browser applies orientation before resizing. Source EXIF is not copied into re-encoded output; color profiles and appearance may change. Inspect important results before sharing.

What are the file limits?

Up to 10 files, 20 MiB per source/output, 50 MiB selected inputs and separately 50 MiB completed outputs, 24 megapixels and 8,192 pixels per edge. Each file has a 30-second processing deadline.

Are my images uploaded?

Images are processed locally without uploading them or saving them in browser storage. Ads make separate network requests. Clear the queue or leave this page to release the results.
