It can be downloaded from its sourceforge page at. The resulting image will be identical to the original visually, but can end up being much smaller. Pngcrush is a command-line application that reduces the size of PNG files losslessly.Trimage is a Linux based image compressor.PNGGauntlet is a Windows PNG image compressor.ImageOptim is a Mac based only image compressor.These tools don't lose any quality, they only re-compress images and remove invisible metadata: CompressPNG is a tool that allows to reduce the palette size to any value between 2 and 256 colors.pngquant is a command-line tool that can reduce large 24-bit PNG to small 8-bit PNG with full alpha transparency.You can often reduce size by 40-60% without noticeable loss in quality. ImageAlpha is a Mac tool that can reduce PNG files using pngquant, pngnq and posterization.Way2enjoy is another online tool that uses same lossy compression to reduce the size of PNG, JPEG & GIF images.TinyPNG is an online tool that uses lossy compression to reduce the file size of PNG images.Depending on the tool and the amount of compression used, the changes in quality may or may not be noticeable. These tools provide the greatest file size savings, but will reduce the quality of the file as a consequence. Java is a registered trademark of Oracle and/or its affiliates.The following is a list of third-party compression tools that can be used to reduce the file size of a PNG file.

Precompiled cwebp conversion tool for Linux, Windows or macOS. The full source code is available on theĬonvert your favorite collection from PNG and JPEG to WebP by downloading the Images to and from the WebP format, as well as tools for viewing, muxing andĪnimating WebP images. WebP includes the lightweight encoding and decoding library libwebpĪnd the command line tools cwebp and dwebp for converting Developers haveĪlso added support to a variety of image editing tools. WebP is natively supported in Google Chrome, Safari, Firefox, Edge, the Operaīrowser, and by many other tools and software libraries. Implementation for the WebP specification, and is available from The standalone libwebp library serves as a reference It can also use a local palette if noĪ WebP file consists of VP8 or VP8L image data, and a containerīased on RIFF. Lossless WebP compression uses already seen image fragments in order toĮxactly reconstruct new pixels. In a block, and then encodes only the difference. PredictiveĬoding uses the values in neighboring blocks of pixels to predict the values Method used by the VP8 video codec to compress keyframes in videos. Lossy WebP compression uses predictive coding to encode an image, the same Which can provide reduced sizes compared to GIF and APNG. Lossy, lossless and transparency are all supported in animated WebP images, Is acceptable, lossy WebP also supports transparency, typically providing ImageOptim is a powerful image lossless compression tool software that provides lossless compression services for PNG images, reducing file size by. Lossless WebP supports transparency (also known as alpha channel) at aĬost of just 22% additional bytes. Lossy images are 25-34% smaller than comparable JPEG images at equivalent WebP lossless images are 26% smaller in size compared to PNGs. Using WebP, webmasters and webĭevelopers can create smaller, richer images that make the web faster. WebP is a modern image format that provides superior lossless and
