HEDEF Hosting

<p>Hedef Image Optimizer — WebP & AVIF is a lightweight but powerful image optimization plugin that converts your JPEG and PNG uploads into modern WebP and AVIF formats.</p>
<p>All conversions happen locally on your server using GD and/or Imagick – there is no external API, no remote storage and no extra monthly bills.</p>
<p>The plugin is developed and maintained by <a href="https://hedefhosting.com.tr/" rel="nofollow ugc">Hedef Hosting</a> and is provided completely free of charge.<br />
If you have ideas, bug reports or feature requests, feel free to email us at support@hedefhosting.com.tr.</p>
<p>It focuses on three main goals:</p>
<ul>
<li><strong>Better performance</strong> – Serve lighter images without visibly losing quality.</li>
<li><strong>Modern formats</strong> – Use WebP and AVIF when supported by your server and your visitors’ browsers.</li>
<li><strong>Simple control</strong> – Configure everything from a single, polished settings page.</li>
</ul>
<h3>Key Features</h3>
<ul>
<li>Automatically convert JPEG/JPG and PNG images to WebP and/or AVIF on upload.</li>
<li>Bulk optimization tool for existing Media Library images, with:
<ul>
<li>Progress bar and live log of processed items.</li>
<li>“Run again” support to refresh images after changing quality or resize settings.</li>
</ul>
</li>
<li>Media Library “Optimizer” column:

</ul>
</li>

</ul>
</li>
<li>Localization:
<ul>
<li>English (en_US)</li>
<li>Turkish (tr_TR) – full translation of the admin UI and bulk screens.</li>
</ul>
</li>
</ul>
<p>Everything is designed to blend nicely into the WordPress admin with a clean, modern UI.</p>
<h3>How It Works</h3>
<ol>
<li>When you upload a JPEG or PNG image, the plugin can automatically generate .webp and/or .avif versions (depending on your settings and server capabilities).</li>
<li>For existing images, use the <strong>Media <span aria-hidden="true" class="wp-exclude-emoji">→</span> Bulk Optimize (NGIO)</strong> screen to scan the Media Library and generate missing next-gen versions in small batches.</li>
<li>On the frontend, you can enable the  integration so that supported browsers will load AVIF / WebP, while older browsers still get the original image.</li>
<li>The plugin stores lightweight stats in attachment metadata (ngio) so you can see how much space you’ve saved on each image and across the library.</li>
</ol>
<h3>Requirements</h3>
<ul>
<li>PHP 8.1 or higher (for AVIF support through GD or Imagick).</li>
<li>WordPress 6.5 or higher.</li>
<li>One of:
<ul>
<li>PHP GD extension compiled with WebP/AVIF support.</li>
<li>PHP Imagick extension with WEBP/AVIF codecs enabled.</li>
</ul>
</li>
</ul>
<p>If your server is missing some of these, the <strong>Server support</strong> box on the settings page will clearly show what’s available and what is not.</p>
<h3>Usage</h3>
<h3>1. Choose formats and automation</h3>
<p>On the <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Image Optimizer</strong> page:</p>
<ul>
<li>Enable WebP, AVIF, or both, depending on your server capabilities.</li>
<li>Turn on <strong>Optimize on upload</strong> if you want new images to be processed automatically.</li>
<li>Enable <strong>Serve via </strong> to send WebP/AVIF to compatible browsers.</li>
</ul>
<p>You can also:</p>
<ul>
<li>Pick a quality level (e.g. 80–85 for most sites).</li>
<li>Enable <strong>Resize next-gen copies</strong> and set a max width (e.g. 2048px).</li>
<li>Enable <strong>Strip metadata</strong> to remove EXIF/IPTC from generated copies.</li>
<li>Add <strong>Exclusion patterns</strong> (one per line) to skip specific images.</li>
</ul>
<h3>2. Bulk optimization</h3>
<p>Go to <strong>Media <span aria-hidden="true" class="wp-exclude-emoji">→</span> Bulk Optimize (NGIO)</strong>:</p>
<ul>
<li>Click <strong>Optimize all images</strong> to start the process.</li>
<li>The progress bar will move as images are processed.</li>
<li>The log will list each optimized attachment.</li>
<li>If you change quality or resize settings later, you can run bulk optimization again – existing next-gen copies will be refreshed.</li>
</ul>
<h3>3. Per-image controls</h3>
<p>In <strong>Media <span aria-hidden="true" class="wp-exclude-emoji">→</span> Library</strong> (list view):</p>
<ul>
<li>Use the <strong>Optimizer</strong> column to see:
<ul>
<li>Status (optimized/not optimized).</li>
<li>New filesize and percentage of space saved.</li>
<li>Links to Re-optimize and Restore original.</li>
</ul>
</li>
</ul>
<p>In the <strong>attachment edit screen</strong>:</p>
<ul>
<li>Use the <strong>NextGen optimization</strong> metabox to:
<ul>
<li>Optimize/re-optimize just that image.</li>
<li>Override the global “Optimize on upload” behaviour.</li>
</ul>
</li>
</ul>

<h4>About the plugin</h4>
<ul>
<li>You can use your Kraken.io API key and secret on as many sites/blogs as you like. We have no per-site license.</li>
<li>All images uploaded throught the media uploader are optimized on-the-fly. All generated thumbnails are optimized too.</li>
<li>The main image upload can be optionally resized – this is useful for preventing user uploads with unnecessarily large dimensions. You can specify the maximum width and/or height in Kraken.io->Settings.</li>
<li>When restricting the maximum dimensions of the main image using the resizing feature, the resulting image is <strong>enhanced</strong> using various advanced techniques, to help prevent downsample artifacts and “haloing” and produce a sharper result.</li>
<li>You can optionally preserve one or more of the Date, Copyright, Geotag, Orientation, Profile EXIF metadata tags.</li>
<li>Images can be automatically oriented according to their EXIF Orientation value – no need to manually rotate images.</li>
<li>All images already present in the media library can be optimized individually, or using the Bulk Action menu “Krak ’em all” feature.</li>
<li>This plugin does not require any root or command-line access. No compilation and installation of any binaries is necessary.</li>
<li>All optimization is carried out by sending images to Kraken.io’s infrastructure, and pulling the optimized files to your WordPress installation.</li>
<li>To use this plugin, you must obtain a full API key and secret from <a href="https://kraken.io/plans" title="Kraken.io - Plans and Pricing" rel="nofollow ugc">https://kraken.io/plans</a>. Our free account comes with a limited quota for testing our premium features, including this plugin.</li>
<li>Works great with WPEngine hosted blogs, including the staging area.</li>
<li>Since version 1.0.4, the plugin will work with local WordPress installations; the client site does not need to be published on the web.</li>
</ul>

<p>★★★★★ <strong>Excellent Option for Image Optimization</strong><br />
  “The real power of Kraken is their “intelligent lossy” optimization. I use it on all my sites and have never once needed to roll back an image because of too much quality degredation. While I hope to see some more advanced settings added to the WordPress plugin in the future, it is a perfect solution as is.” – <a href="https://profiles.wordpress.org/collinmbarrett" rel="nofollow ugc">collin</a></p>
<p>★★★★★ <strong>Quality results, quality service</strong><br />
  “The plugin works really well and effortlessly, and the support is prompt, thoughtful, and thorough. I’m hooked.” — <a href="https://profiles.wordpress.org/illustrata" rel="nofollow ugc">illustrata</a></p>
<p>★★★★★ <strong>Optimize according to Google Pagespeed</strong><br />
  “Kraken was instrumental in optimizing images to comply with Google’s Pagespeed analyzing tool. Our travel blog travelmemo.com now sports Google’s ‘mobile friendly’ tag for mobile searches” — <a href="https://profiles.wordpress.org/qualterio" rel="nofollow ugc">Walter Schaerer</a></p>
<p>★★★★★ <strong>Perfect solution to speed up site!</strong><br />
  “I love this plugin! All the questions I had are quickly responded to and I see a huge saving with image size without losing the quality. I highly recommend this plugin!” — <a href="https://profiles.wordpress.org/ezone69" rel="nofollow ugc">ezone69</a></p>
</blockquote>
<p>Once you have obtained your credentials, from your WordPress admin, go to the Kraken.io settings page. The from there you can enter your API credentials, and select your optimization preferences. Once you have done this, click on <strong>Save</strong>. If everything is in order, it will simply say “settings saved” and give you a reassuring green tick that your credentials are valid. You can now start optimizing images from within Media Library. Any image you upload from now on, through any of the media upload screens will be optimized on-the-fly by Kraken.io.</p>
<p>For advanced users, there is a third party WordPress Command Line Interface (CLI) tool to allow image optimization from the command line, or by using cron. For details, visit: https://github.com/tillkruss/wp-cli-kraken</p>
<p>Please send bug reports, problems, feature requests and so on to support (at) Kraken dot io, or directly to the author of this plugin.</p>

Kraken.io Image Optimizer

- It works with 1 image but not at Google PageSpeed standard
- It doesn't work with bulk action
- The worst thing is I inputted my credit card there and they refused to let me cancel my subscription, what a very bad thing from kraken.io

Does not work for bulk actions, subscription cannot be cancelled

As others are noting here, their customer service is terrible. In fact I'd use the word "non-existent".

After signing up with an account I decided that the service was no longer what I needed and contacted them to delete my account. Multiple times, in different ways, I've contacted their customer support about this and never had a response. Currently breaching GDPR rules, they're going to be reported.

Thank goodness I never handed over any payments to them.

Terrible Customer Service

This plugin allows you to optimize your WordPress images through the Kraken.io API, the world's most advanced image optimization and resizing API.
