Learn The Ropes With These Hands-On Smush Tutorials

Compress Image While Preserving Image Quality

Some image compression tools destroy images with as much as a 30% loss in quality. Our servers strip hidden bulky information from your images and reduce file size without affecting the appearance.

Smush meticulously scans every image you upload – or have already added to your site – cuts all the unnecessary data and scales it for you before adding it to your media library. And it can serve images in the WebP format.

Βελτιστοποίηση οποιαδήποτε εικόνας σε οποιοδήποτε κατάλογο αρχείων

In addition to smushing your media uploads, you may want to compress the images stored in other folders. Smush now lets you compress any image in any directory so that you can optimize all the images on your site – including NextGEN images, images stored on Amazon S3 using WP Offload Media and images in EVERY WordPress plugin and theme package!

Compatible with Your Favorite Themes, Page Builders and Media Library Plugins

No matter what theme or plugins you use to better manage your WordPress media library, Smush has you covered. Check out just a few of the popular products Smush is working with to help make your site faster and more efficient:

Incorrect Size Image Detection

Smush includes a wrong size image finder. Activate and your images will be highlighted with smart tips for scaling your images. Quickly locate the images that are keeping you from getting that perfect 100 on your Google PageSpeed test.

Defer Offscreen Images

Smush has lazy load built-in. If your page has a bunch of images below the fold, lazy loading will drastically speed up your page by serving only the images being viewed and delaying others further down the page.


“Δεν είχα ιδέα ότι ο χρόνος φόρτωσης της σελίδας μου ήταν αργός λόγου των εικόνων που είχα. Το πρόσθετο διπλασίασε την ταχύτητα φόρτωσης.” – karlcw


“Βελτιστοποιώ τις φωτογραφίες μου στο Photoshop, αλλά το Smush το κάνει τόσο εύκολο – και το κάνει αυτόματα. Μπορώ να κάτσω πίσω και να απολαύσω την ταχύτητα.” – helen432


“Το Smush βοήθησε στη μείωση του συνολικού μεγέθους αρχείων στον ιστότοπό μου και στην αύξηση της ταχύτητας. Μπράβο παιδιά!” – pdci


“It’s very discrete and does not bother me with an API key or other additional installation steps. The main dashboard of the plugin gives me nice insight. Overall it really fits my needs and I’ll be willing to upgrade to pro if my needs change. I’d recommend it to clients/friends without hesitation. Keep it up!” – tarkan_

What about Multisite?

Smush can be used to optimize all the images across your entire network! Use global settings or configure each site individually.

Smush is super easy to use – no confusing compression software settings. Smush images in your library one at a time or bulk smush up to 50 images at a time. Plus, configure auto-smush to asynchronously scale and compress some or all of your images as they are being uploaded – it’s incredibly fast.

The faster your site loads, the more Google, Bing, Yahoo, and other search engines will like it. Your site will load faster and rank higher.

Συχνές Ερωτήσεις

I just finished running Smush and Google PageSpeed still says my images need compressing and resizing. How do I fix it?

This means your images were not properly scaled for where they are being displayed. Scaling images before uploading them can be time-consuming but can save space and speedup load time. First, determine what size your image needs to be. You can use the built-in images size detector included in the free version of Smush to find what height and width your image should be. Once you know how large the image should be, scale your images to the right size.

PageSpeed Insights is telling me to defer offscreen images. Can Smush fix that?

Lazy Load will defer your offscreen images from loading until they are needed. From the Smush Dashboard, select Lazy Load and click Activate. Smush Lazy Load works out of the box or can be customized based on your needs.

Tip: If you’re having any issues or want to save a ton of time, the Smush Pro CDN includes auto-resizing.

Το Smush διαγράφει ή αντικαθιστά τις αρχικές εικόνες πλήρους μεγέθους;

Nope. WordPress crops and resizes every image you upload for embedding on your site. By default, Smush only compresses these cropped and resized images, not your original full-size images. To compress your original full-sized images, use Smush Pro.

Τι είδους αρχείο θα πρέπει να χρησιμοποιήσω για τις εικόνες μου (GIF, PNG, JPG);

Τα αρχεία GIF είναι μεγάλα και δεν μπορούν να βελτιστοποιηθούν πολύ. Θα πρέπει να χρησιμοποιούνται μόνο αν η εικόνα είναι κινούμενη.

Το PNG είναι το καλύτερο για γραφικά που παράγονται από υπολογιστή ( λογότυπα, γραμματοσειρές κ.λπ.), εικόνες με λίγα χρώματα ή εικόνες με διαφάνεια.

Το JPG χρησιμοποιείται για φωτογραφίες ή εικόνες με πολλές χρωματικές παραλλαγές.

Tip: The Smush Pro CDN includes WebP compression – sharper images that are 25 to 30 percent smaller than JPEG and PNG files.

I’m a photographer. Can I keep all my EXIF data?

Yes! EXIF data stores camera settings, focal length, date, time, and location information in image files. EXIF data makes image files larger but if you are a photographer, you may want to preserve this information. We have included the option to preserve EXIF image data in Smush.

I just ran Bulk Smush and some of my images didn’t get compressed. Why would this happen?

First, check to see if you’re receiving any server errors. If your images seem to be processing correctly, check the file size of the images being skipped. Images over 5mb will be skipped. To compress images up to 32mb, get Smush Pro.

Ενεργοποίησα το Smush και δεν βλέπω καμία διαφορά στην ποιότητα της εικόνας. Πώς θα έπρεπε να ξέρω αν λειτουργεί το Smush;

Καλη ερώτηση! Είναι σημαντικό να καταλάβετε το Smush είναι ένα εργαλείο βελτιστοποίησης που συμπιέζει εικόνες χωρίς απώλειες για να εξοικονομήσει χώρο στο διακοσμητή και να επιταχύνει τον ιστότοπό σας. Το Smush συμπιέζει τα δεδομένα από τα αρχεία εικόνας, τα οποία θα εξοικονομήσουν χώρο, θα αλλάξουν το μέγεθος των τεράστιων εικόνων και θα βελτιώσουν την ταχύτητα χωρίς να αλλάξουν την ποιότητα.

Μπορείτε να παρακολουθείτε τις αλλαγές μεγέθους αρχείου στη βιβλιοθήκη πολυμέσων σας, την εξοικονόμηση μεμονωμένων εικόνων, την εξοικονόμηση αρχείων στους καταλόγων και την συνολική εξοικονόμηση με στατιστικά στοιχεία Smush. Αν θέλετε να δείτε κάποια επιπλέον μαγεία, εκτελέστε δοκιμές ταχύτητας πριν και μετά τη σελίδα με το WP Checkup ή το Google PageSpeed Insights. Κάθε λίγη εξοικονόμηση πόρων είναι σημαντική όταν πρόκειται για την ταχύτητα σελίδας!

Δεν μπορώ να χρησιμοποιήσω μόνο το Photoshop ή άλλη εφαρμογή επεξεργασίας εικόνας για να βελτιστοποιήσω τις εικόνες μου;

Optimizing all the image sizes generated by WordPress, images being imported from plugins and themes, and images from other web sites is a painful and time-consuming process.

Smush automatically handles optimizing all your images no matter where they come from and can be used as a standalone tool or alongside Photoshop.

My Google PageSpeed test is telling me to serve images in Next-Gen formats. Can Smush do that?

WebP and other Next-Gen formats are not supported on all browsers and require fallback images. For that reason, WebP conversion is only available in Smush Pro. Smush Pro converts images to WebP for a 25-30% savings over JPEG and PNG and serves fallback images on unsupported browsers.

Είναι “optimize” ή “optimise”?

It depends what side of the pond you live on…but whether you say optimize, optimise, optimizer, or Smush goddess of speed, this plugin will make sure your images are loading lightning fast.
