WebP can reduce file size for many PNG images, which can make it useful for images delivered on the web. Actual results depend on the image content and selected quality, and some PNG files can produce larger WebP files.
PNG uses lossless compression, supports transparency, and is common for graphics, screenshots, and transparent assets. WebP supports transparency and the format supports both lossy and lossless encoding, often providing smaller web images.
This converter's adjustable-quality output may change RGB or color detail while retaining transparency. The WebP output is not guaranteed to be smaller than its source PNG.
Higher quality generally keeps more color detail but may produce larger files. Lower quality may reduce file size while introducing visible compression artifacts. Results vary by image content. Savezly uses 90% as its tested default, not as an industry standard.
PNG and WebP both support transparency. Savezly does not paint a replacement background, so transparent areas remain transparent and semi-transparent areas remain semi-transparent. Normal lossy WebP quality may still alter RGB or color detail.
Select multiple PNG files and convert them in one session. Savezly processes files sequentially, gives each file an independent result, and continues after an individual failure. Successful WebP files are downloaded individually.
Image conversion occurs locally in your browser. Image bytes are not uploaded to Savezly for conversion, no external conversion API is used, and no signup is required.
Static PNG images are supported up to 16 megapixels and 8192 pixels on either dimension. Metadata and color-profile preservation are not guaranteed.
Yes. You can convert PNG images to WebP for free with no signup required.
Yes. Files are processed sequentially, and every successful WebP result is downloaded individually.
Yes, for supported static PNG images. Transparent and semi-transparent areas are retained in the WebP output.
It can. The adjustable WebP conversion may use lossy compression, so color detail can change depending on the selected quality.
No. Conversion occurs locally in your browser, and image bytes are not sent to Savezly for conversion.
WebP can be smaller for many PNG images, but this is not guaranteed. Some PNG files may produce larger WebP files.
Higher quality generally retains more color detail but may produce a larger file. Lower quality can reduce size while adding compression artifacts. Savezly uses 90% by default, but the best setting depends on your image and intended use.
WebP as a format supports lossless encoding, but this converter does not expose or promise an explicit lossless mode. A 100% quality setting is not guaranteed to create lossless output on every browser or device.
