How to save webp file as png. How to make a webp file into a png.

You never sailed on the web and found an image you would like to save. Right-click and select Save only to find out that it is a .webP file? What is a .webP file and why is it used on the web? How can you convert it to a normal image file you can view? Web pages that present images, and there are few who are not these days, can be slow to display. If the images are large or if there are many, they add to the total web page size and the larger size, longer adopt to download and view in the browser. The large web pages are also added to the load on the web server and when there are many visitors who require web pages, the server will slow down and the site seems to be lazy and not responding. If the images may be made smaller, they would download more quickly and the web server would have less work to do. The website would seem to be more reactive and web pages would have displayed faster for visitors. In addition to this, there is the advantage of reduced bandwidth for mobile users. Light web pages use less mobile phone data. The Google WebP file format invented the WebP file format as a way to reduce the size of the images used on the web. A .webP image file is smaller than the .jpg and .png files that are normally used on websites. JPEG images use what has called a loss compression technique to make smaller image files. The image information is discarded, but with only a small compression is very difficult to say and the result looks like the original image. WebP can store images using a loss compression technique. However, for the same image quality WebP files are smaller. PNG images (often used instead of the gif these days), use compression to reduce file size, but are an example of a file format without loss. No information is discarded during compression and the resulting image is identical to the original. Each pixel is preserved. WebP can be used to store images even in sizes without loss, but the resulting file is smaller than the PNG files. Get more information about WebP files here. Who uses WebP files? WebP would seem to be a great way to accelerate the visualization of the web page and the performance of the website. It has been around for many years, but for some unknown reason, app and web developers have been slow to incorporate it into their software and on Web sites. The image file format has always been supported by Chrome because WebP is the invention of Google. For some time, Chrome was the only web browser that could show .webp files on web pages, but now Opera and Firefox support it both. The original Edge in Windows 10 didn't support it, but Microsoft is going to a Chrome-based engine for Edge, so support for .WEBP images must be integrated. Apple has not added support for .Web files in Safari and we can only hope it adds it to a next update. The lack of universal support for .WEBP images in Web browsers is holding its use. The web could be faster and lighter with .WEBP .WEBPSo why doesn't everyone support it? It is complicated right now and it seems that in order for both to use a website to use Webp, you need to store the images twice, once in each format. The code within the web page must then identify which browser is being used and download the appropriate image format. This is too much work for most website developers. It is easier to stay with a single file format that is displayed in every browser. Convert From / From .WEBP Google provides a collection of tools for people who want to convert images to the Webp file format or convert them from it to a standard file format. The filenames are quite explanatory and libwebp-1.0.3-windows-x86.zip is for Windows users and libwebp-1.0.3-mac-10.14.tar.gz is for Apple Mac users. Unzip the archive and the Readme.txt file provides information about the utilities. For example, in the Bin folder is cwebp.exe to convert images on Webp and dwebp.exe to convert Webp images on standard image formats. To convert an image to Webp, you need to open a command prompt window (press Windows + R and enter CMD), access the folder containing the tool and images CWeBP.exe. Who has time for command line utilities though? There are simpler ways to convert images to and from the .WEBP file format. Convert WebP with Aren Paint Command Line Tools is a lot of fun and is not easy to use, so if you want a simple tool to convert Webp images to a more common file format, use Windows Paint. This has been part of Windows for decades and still has its uses today. Load the .WEBP image to paint, then select Save As. There is a choice of JPG, BMP, GIF and PNG. There is no batch conversion and you have to do it one at a time, but otherwise it works fine. Convert Webp with Sloosh Sloosh is a free online image conversion and compression tool from Google and is great for optimizing images to be used on websites. Open the site in a browser, then drag an image from the disk (PC or Mac) and drop it on SQUOSH. You can convert to or from Webp by selecting the file format in the right pane in Compress. When you convert to Webp, there are quality efforts and sliders. Drag the maximum quality effort and drag to the minimum acceptable level. Drag the left and right vertical bar above the image to see it before (left side) and after (right side). The file size is displayed at the bottom of the right panel and there is a download button in the corner when you are satisfied with the size and quality. I have written a complete guide to SLOOSH HERE Squash Images with SQUOSH to improve the performance of the website you can reduce the size of the of photos like the one above the crazy little levels and that one is 97% smaller than the original PNG file that was uploaded. The amount of compression is possible depends on the type of content. I was going to show the effects of compression using that photo above, but it's too hard to see. You have only a slight blur of fine details which is not apparent unless you I can see the original. Even then it's difficult. The best example I could do is a screenshot. The first is saved as JPEG and the second is a WebP image with the same file size. Look at the quality of the text. Highly compressed JPEG image A WebP image with the same size as the WebP file retains image details much better when using high compression and small file. This happens in the photos, but it is more difficult to see. (Technically the WebP image above is a PNG because if it were a WebP then it would not appear in some browsers. PNG is a file format without loss, so it is exactly like the WebP image.) For permanent links you can use: Image PNG converted: WebP is a relatively new image format with good compression and image quality, but it is not yet supported by all web browsers and image viewers. If you have an image in WebP format and want to convert it to PNG format, this tool is one of the easiest ways to do so. All you have to do is upload the WebP file and click "Converts". Then you can download or edit the product PNG. Animated WebP files will be converted to APNG. Use version 2.* for TYPO3 CMS LTS 8 and 9 and >= 3.* for TYPO3 CMS >= 10.4 ? If you update from a version before 2.0 you need to save the configuration again! What are you doing? Adds a WebP copy created automatically for each jpg/jpeg/png/gif image processed in the What is WebP format and why do I want it? WebP is a modern image format that provides a lossless compression and superior loss for images on the web. Using WebP, webmasters and web developers can create smaller and richer images that make the web faster. WebP lossless images are 26% smaller than PNGs. WebP lost images are 25-34% smaller than JPEG images comparable to an equivalent SSIM quality index. Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. For instances where RGB compression with loss is acceptable, lossy WebP also supports transparency, typically providing 3# smaller file sizes than PNG. Add by composer: compound require ?plan2net/webp? Install and activate the extension in the Flush TYPO3 and PHP Cacheick extension You can test the supportwith e.g.: (you should return yes) or use ImageMagick with e.g.: convert version|grep webp (you should return a list of supported formats including webp) These are examples, check your system documentation for more information on how to verify webp support on your platform. Extension Settings You can set parameters forin the configuration of the extension. Parameters Parameters = Image / JPEG: -Quality 85 -Define Webp: Lossless = False | Image / PNG: -Quality 75 -Define Webp: Lossless = True | Image / GIF:: ? Quality 85 -Define Webp: Lossless = True find a list of possible options here: If you want to use an external binary, you must provide a String option with exactly the Two%s signals for the original file and the name of the target file. For example: image / jpeg:: / usr / bin / cwebp -jpeg_like% s -o% s | image / png:: / usr / bin / cwebl -llessless% s -o% s / Speed ??/ WebP / Docs / CWEBP WARNING Try setting a higher value for the quality first if the image does not fit your expectations, before trying to use Webp: Lossless = TRUE, as this could also lead to a file higher than the original! convert_all # cat = base; type = boolean; Tag = Convert all images to local memory and write and save a copy in Webp format; Disable to convert images to the _processed_ folder Only convert_all = 1 From version 1.1.0 All images in each local and writable archive will be saved as a copy in Webp format by default (instead of only images modified by TYPO3 in the processed storage folder). If you want to restore the previous behavior, set this flag to false (disable the check box). silent # cat = base; type = boolean; Label = Label Output (Stdout, STDERR) from the external converter command Silent = 1 Since version 2.2.0 it is possible to suppress the output (Stdout, Stderr) from the external converter (Linux only). Sample Webserver Configuration Adapt the following specific requirements, this is just a sample configuration. nginx Add a map directive in the global Nginx configuration: Map $ http_accept $ webp_suffix {default "; "~ * webp" ".web"; } and add these rules to the server configuration: Location ~ * ^ / file admin /.+ \. (PNG | JPG | JPEG) $ {add_header Vary accepts; Try_Files $ URI $ webp_suffix $ uri = 404; } Location ~ * ^ / Other-Storage /.+ \. (PNG | JPG | JPEG | GIF) $ {ADD_HEADER Vary Accept; Try_Files $ URI $ webp_suffix $ uri = 404; } Make sure there are no other rules that already apply to the specified image formats and prevent further execution! Apache (.htaccess Example) rewriteengine on rewritecond% {http_accecept} Image / Webp RewrititudeCond% {document_root} / $1. $ 3. $ 3. DEBP-RECRITERULA ^ ((FileADMIN | Other-Storage) /.+) \ . There are no other rules that already apply to the specified image formats and prevent further execution! Check the generation and delivery of successful Webp image to make sure everything works as You need to check two things: the generation of Webp images on the Webp image series website to the generation of Webp images client Go to Filoadmin / _Procead_ and check the subfolders for files with .web. .web. For each processed image file there should be a second file with the same file name plus .webp extension: csm_foo-bar_4f3d6bb7d0.jpg csm_foo-bar_4f3d6bb7d0.jpg.webp Delivery of WebP images to the client Open a processed jpg or png image (see above) in the browser, for example. Check the response headers in your browser's development tools. Despite the suffix of the .jpg file, you should get Content-Type: image/webp. Troubleshooting and Logging If something doesn't work as expected, take a look at the log file. Any problems are related to the TYPO3 log (since version 2.0), normally found in var/log/typo3_*.log Converted files that are larger than the original are removed automatically (since version 2.1.0) and the conversion will not be reactivated with the same configuration. Removing Processed Files You can remove .webp files created at any time within the TYPO3 CMS backend. Go to Admin Tools > Remove Temporary Assets Click the Temporary File Scan button In the modal click the button with the storage path Even if the button names only the path of the _processed_ folder, all processed files of the storage are actually deleted! Alternatives You can get the same result using the Apache mod_pagespeed or nginx ngx_pagespeed modules from Google with a configuration like: pagespeed EnableFilters convert_jpeg_to_webp; pagespeed EnableFilters convert_to_webp_lossless; but that requires more knowledge to set up. Note that this extension puts an extra load on the server (every processed image is retracted) and probably creates a lot of additional disk space-consuming files (size varies depending on the configuration!). Inspiration This extension was inspired by Angela Dudtkowski's cs_webp extension which has some flaws and hasn't had any updates since early 2017.
