    You guys/gals are great. So patient. When I asked my iPhone and other Droid owner friends to check it out and it was fine...your solution of clearing the catch of course worked. Still, optimizing photos for the web with photoshop was worth the time.

    I've been telling lots of people they are crazy not to use Wix.

    I wrote 10,000 lines of code in the day with dBase. I created a web site from scratch writing code years ago.  This is simply amazing. THANKS

      Thank you for contacting us and I'm sorry for the inconvenience. 


      I've checked the speed test you performed and saw that your site got a great score!


      I can also see that your site failed the progressive JPEG's test. Please follow this link providing you with steps on how to deal with this issue.


      In general, please note the performance of your HTML5 site is affected by a number of factors, including the size of your website and amount of content on it, your internet connection speed and your browser version. Using the most updated browser version and ensuring that your internet connection is stable and running at a high speed will help ensure that you are viewing your site in optimal conditions.


      For best performance, it is recommended to follow these guidelines:


      1. Optimizing the images on your site will have a great affect on its performance and loading time. For tips on adding images to ensure they take up as little space as possible, please click here.


      2. Distribute your content on several pages. This will improve loading times and overall load.

      3. Fonts take up a lot of CPU power and loading time. Please try not to use more than 2 fonts on a single page. Fonts in plain, bold, italic, bold & italic are all considered to be different fonts! The best solution would be to use browser text and not simple text.


      If you need any further assistance please let us know.

      Thanks, Rony Customer Solutions

      Ok, working on it. Instructions say to convert to .png but when I converted a 1.5mg jpg to PNG it became 12MB. That doesn't seem logical. You also say The best solution would be to use browser text and not simple text. What is "browser text" and can I have that in mobil only?

    • Noa Wix Team

      Replied by Noa 8 hours ago



      We did not necessarily say you have to change the .jpg to .png. You should see which is better - in this case it seems that .jpg are preferable.


      By browser text we mean text that is inserted directly to the editor rather than simple text- which is text that is copied and pasted from another document.


      The loading time of your site is excellent- less than one minute, so I wouldn't hassle over this too much, but I would advise to keep these details in mind when updating the site.


      Let us know if we can further assist,

      Your support is amazing. 

      However, after my problem is the loading on my Samsung Galaxy s4. It was instant, then I changed a few fonts and added just a couple of jpgs and it won't load on my phone at all.

      I followed the instructions on RGB color, size, save for web as png, and replaced every jpg I could find but the speed test said it failed everything, then another test said failed jpeg again.  The link said png was the ideal. I guess I could try jpeg but since it might be something else I did......

      test: http://www.webpagetest.org/result/140727_TV_HDH/

      Somehow I mucked it up, at least for mobil. Does it load on your smart phone? The first page loads but I get the rotating cog and it is a blank page going to any other page. Used to work.

      Is it time to hire the pros you list?

      Thanks so much for your feedback!


      I tried loading the site on an iphone and experienced no issues at all.

      Please try clearing the cache of your mobile browser.

      For instructions on how to clear the cache on your mobile device, please select your device from the list below:







      Regarding the "F" grade in the test  of the progressive jpegs.

      progressive jpeg is one format of many image formats (png, jpg etc..). The webpage test tests this format specifically. However, progressive jpeg is not neccesarilly the best format for your site and needs, therefore this "f" grade is not so relevant. You can feel pretty secure using the file formats we recommended earlier.


      All the best,

      Thank you for reaching out,


      Looking into your webpage I can see you've placed all the products on one page, since this is a big amount of data that needs to be loaded, at once, it takes a longer time to load.


      I would recommend spearing your products across 3-4 pages.


      I also suggest making sure that your images are optimized for the web.

      Please take down the images you placed on your site and convert them to .jpeg files, this will compress the size of your images by more than half and will allow your site to load faster.

      You can get more information on converting images to a .jpeg format here.


      Let us know if you need additional assistance.

      All the best, Dean - Wix Team

    Website taking a long time to load.

    I get the feeling it might be because of the third party addons can someone take a look and give me some advice on where I can improve this. 10 second load time I think would be fine. Here are the results I had. The website is www.themechanicaltraveller.co.uk

      Thanks for contacting Wix Support.

      I have checked your site using a speed test, the results of which can be seen here. Your site received a score of 'F' for progressive .jpegs.

      To rectify this, you will need to save your images in progressive .jpeg format. If you are using Gimp to improve your image quality, you will be able to make these changes in the Advanced Options section.

      A great way to increase site performance is to optimize the images that you use. To find out more, please click here!

    Hello - WIX has been great for us for many reasons, except for LOAD TIME.  I have run the test several times and usually it takes 13-15 seconds for anything to appear, and up to 45s for the main page to fully load!!

    Site: http://www.mtutd.info

    Results are here.

    Any ideas/suggestions?

    I know we have a lot of content on the main page...our marketing guys wants it that way. If we could get the background to appear quickly I think it will help keep users on the site longer. Would appreciate your thoughts on this.

      Thank you for your question.

      I have also run a speed test on your sites, whose results may be reviewed here.


      I can see your site contains a lot of heavy images. Moreover, as you mentioned, your homepage contains a lot of heavy content.


      Please do the following:

      1. Spread content across your site away from the homepage. You can use our List Builder in the process.

      2. Please compress your images. You can find instructions here.

      All the best, Or

      Hello Or   - thanks for your ideas!  I compressed all the images on the main page, the largest being the back ground at about 330KB (any lower and it gets blurry), but most images are around the 100 KB or less size. Most of them were already compressed, but I did find two images that I was able to shrink quite a bit. 

      The load time improved, but it is still way too slow (9 - 15 seconds for the first thing to appear)...and I need to get that down as low as possible.  Any other ways around this? Is there a way to have a "LOADING" ticker or graphic appear in the first second?  There is research that shows this type of gadget improves conversion.  I know a landing page might help as well, but that's something WIX has not developed yet.

      I know there is too much content, but that's not something I can change (marketing department).

      Also, the speed test's graph of "bytes" seems to show that images are not a big factor in load, but Javascript seems to be the culprit?  Maybe I'm not interpreting that correctly?

      So any tips, ideas, thoughts, please share - this is key to growing our site  and lowering that bounce rate!!

      I do not know why you received such high results.

      When opening your site the loading speed is fairly good.


      I ran another test- the results are much better.See them here


      If you look at the pie charts at the bottom of the test you'll see that most of the elements effecting the slow loading are js and images.

      js= java script. This is the result of the large number of components.

      images= in the results, you can also look at the table and see which images exactly load slower than others. Search for the bars which are longer, and copy the url written next to it. Open the url in a new browser window and you'll see which images should be further optimized.


      I hope this is helpful!

      Thank you Noa - I think the difference in our test results is I used Tokyo or the speed test since our user base is predominately SE ASIA. Does that make sense?

      Anyway, it is better...4 seconds until the background appears, and before that it is all JS..is there any way to force the background image to load before the JS???

      Good Work Wix!! - appreciate the fast response times.

    I have an issue with the menu page loading very slow and also loading with some technical issues on mobile devices.  The page itself contains about 10 or so menu sections and all are identical, but the font colors are not correct in some sections and the page has some issues.

    Please help!  Thanks.

      Hi Rony,

      Thanks for the info.  Yes, I forgot to compress the images so I will fix that.

      I have attached 2 screenshots of the mobile site so you can see the issues I have run into.  In image1 the menu has a large gap before it displays and in image2 you can see the fonts are not matching the fonts of the desktop site (colors, size, etc.).  Maybe you can shed some light on this.  Thanks.


    • xiaoding

      Replied by xiaoding 8 hours ago

      I solved the font problem.  Didn't realize I could customize the mobile font independently of the desktop version.

      I haven't figure out however how to fix the spacing problem on the menu page.  The gap that shows from the Menu title before you actually get to see the menu.
