This article will give a method to fix it.<br \/>\nAll you need is to insert the following code into the theme functions.php or a plugin that you use on your website:<\/p>\n<p><code>add_filter('jpeg_quality', function($arg){return 100;});<\/code><\/p>\n<p>Setting to 100 means that WordPress will compress in the best quality possible. For many people, this is important, I do not use this trick on your site, but if you are a photographer then this information will be useful.<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression.png\" alt=\"\" width=\"180\" height=\"180\" class=\"alignleft size-full wp-image-138\" srcset=\"https:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression.png 180w, https:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression-150x150.png 150w, https:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression-148x148.png 148w, https:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression-31x31.png 31w, https:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression-38x38.png 38w, https:\/\/sloupok.com\/wp-content\/uploads\/2013\/07\/jpegcompression-144x144.png 144w\" sizes=\"(max-width: 180px) 100vw, 180px\" \/><br \/>\nIf on the contrary there is a desire to reduce this value you can also do this by changing the value to 80 for example, to increase the download speed.<br \/>\nOf course it would be interesting to find out how to change the compression quality of other images, not only JPEG, I hope to be soon.<br \/>\nPlease note that the code will work in versions of WordPress 5.3 and newer, older versions should use the code:<\/p>\n<p><code>add_filter( \u2018jpeg_quality\u2019, create_function( \u201d, \u2018return 100;\u2019 ) );<\/code><\/p>\n<p><script type=\"text\/javascript\"><!--\ngoogle_ad_client = \"ca-pub-6851959002649060\";\n\/* mobilnii sloupok *\/\ngoogle_ad_slot = \"3173373593\";\ngoogle_ad_width = 320;\ngoogle_ad_height = 50;\n\/\/-->\n<\/script><br \/>\n<script type=\"text\/javascript\"\nsrc=\"http:\/\/pagead2.googlesyndication.com\/pagead\/show_ads.js\">\n<\/script><br \/>\nif you have questions about the article, you can ask them in the comments below.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many of those involved in professional photography noticed that when downloading photos in WordPress lose some image quality.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"publish_to_discourse":"","publish_post_category":"","wpdc_auto_publish_overridden":"","wpdc_topic_tags":"","wpdc_pin_topic":"","wpdc_pin_until":"","discourse_post_id":"","discourse_permalink":"","wpdc_publishing_response":"","wpdc_publishing_error":"","footnotes":""},"categories":[1],"tags":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/posts\/133"}],"collection":[{"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/comments?post=133"}],"version-history":[{"count":0,"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/posts\/133\/revisions"}],"wp:attachment":[{"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/media?parent=133"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/categories?post=133"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sloupok.com\/wp-json\/wp\/v2\/tags?post=133"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
