Once installed, you just have to provide the path of the image you want to convert. 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 Apart from format conversions, it also supports cropping, resizing, blurring, flipping, joining, and many more operations on image files. This is an excellent tool from ImageMagick for all our image manipulation needs. Images to and from the WebP format, as well as tools for viewing, muxing andĪnimating WebP images. RawTherapee is another cross-platform, free and open-source RAW image processing application supporting different image editing operations and a large number of file handling. To convert images from one format to another, we can use the mogrify command. 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 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. Or, run the following command in your terminal.WebP is a modern image format that provides superior lossless and Almost all the tasks which can be performed using usual GUI tools can be done using ImageMagick’s convert command line tool.įor a complete list of all the things convert command can do, see the convert man page. In a similar way, other attributes can be modified. And of course, larger image size too as compared to high compression levels. └ Note: Lower compression level means better quality of image. To change the quality index (compression level) of a JPEG image, use: convert test.jpg -quality 15 test_2.jpg To change contrast level of an image, use : convert -brightness-contrast x5 test.png test_2.png To change image brightness, use: convert -brightness-contrast 10 test.png test_2.png convert test.png test.jpg Change Image Brightness and ContrastĬonvert can be used to modify attributes such as brightness, contrast, compression level, etc. It supports huge number of formats.īelow is an example command to convert a PNG image to JPG format. The convert tool can convert images from one image format to the other. # This keeps the width but changes height to 200 Convert Image Format # This keeps the height but changes width to 300 # 300 is the width to be converted to in pixels, and 200 is the height in pixels # Here test.png is the source image, test_2.png is the name for converted image To resize an image, we use the flag -resize: convert test.png -resize 300x200 test_2.png To install on CentOS and Fedora, run: yum install ImageMagick Resize an Image using Convert └ Note: For older Ubuntu versions (version 14.04 and below), you need to use apt-get instead of apt. If it is not installed, we can install it on Ubuntu and Debian with: sudo apt install imagemagick Installing ImageMagick ( convert)įirst verify if ImageMagick is already installed using: convert -version It consists of many tools with number of options for image modification, conversion, etc. ImageMagick is a suite of image modification software for Linux.
