TinyPNG: Website Image Optimizer

If you are seriously trying to raise your SEO so that search engines rate your posts well, you need to make sure your site speed is optimum.  One way to help with site speed is to optimize your images.  In this post, I will introduce tinyPNG, website image optimizer.  It is a tool you can use to compress your images to as small a size as possible, without losing the quality of the picture.

Company name:  tinyPNG

Website:  https://tinyPNG.com

Price:  Free, or pro upgrade for $25

Overall rank:  4.7 out of 5.0

This website provides smart compression for both PNG and JPG  images.  It reduces the file size by searching the colors used and then selectively decreasing the number of the colors in the image.

By this technique, one can reduce the number of bytes required to store the data.  Though the effect is nearly invisible, the compression makes a very large difference in the size.

Important:  TinyPNG is the only widely supported format of this type that can store partially transparent images.

Web Interface Pro:  You can upgrade to pro for $25.00. For the price, you get a full year of compressing messages, using the drag and drop web interface.  For this upgrade, you can sign up as an individual or with your entire team, helpful if you are all working on the same project.

With the Pro, you can drag and drop more than 20 files at once.  You also will have the 5 mg size limit removed.

There is an automatic subscription renewal for the Pro package, but you can cancel that at any time.

If you do a side by side comparison of pictures, you cannot tell the difference.

When you upload a PNG (Portable Network Graphics) file, and put it into the tinyPNG magic box, similar colors in your image will be combined.  This is called quantization.

By reducing the number of colors, a 24-bit PNG file can be converted into a much smaller, 8-bit indexed color images.  The process will also strip all unnecessary meta data.  You will end up with better PNG files with 100% support for transparency. In one example given, the file size was reduced by more than 70%.

TinyPNG compression will save bandwidth and loading time.

The images will work well on mobile devises, as the tinyPNG files display perfectly on all modern browsers.

Chrome, Firefox and Safari also will support APNG files (animated PNG).  It’s good to know, though, that Microsoft Edge will not support animated PNG.  If you have a Microsoft Edge browser, you can go to APNG support on the Microsoft Development Feedback Site and request that they support them.

What about tinyPNG’s Photoshop?

If you desire, you can export your images as 24-bit transparent PNG files and then upload them to tinyPNG.  Use Save for Web to export your images as 24-bit transparent PNG files.  Then upload them into tinyPNG.  They will be converted to tiny indexed PNG files.

You can also install the tinyPNG Photoshop plugin.  The cost is $65.00. This plugin will allow you to scale, preview, and save compressed PNG and JPEG images straight from Photoshop.1 panda chewing bamboo

TinyPNG was created to make websites faster and more fun to use, and offers the best compression.  JPEG compression was added in 2014.  Then, in 2016, support was added for animated PNG.

If you use the tinyPNG website and do not have the plugin, compressing images for your website is free for everyone.  If you want to show your appreciation, you can make a donation (tinyPNG accepts PayPal.)

With the plugin, you will gain support as needed and complete installation instructions.

Developer API

The purpose of Developer API is to automate your JPEG and PNG compression jobs.  A space is provided on the tinyPNG website for you to enter your email address, and you will be sent your API key.

Once you get your key, you can immediately start shrinking images.  You use the same API key for either JPEG or PNG.  You only have to upload the search image and download the result.  Everything else happens automatically.

Preserve Metadata

You can choose to preserve copyright information, the GPS location, and the creation date in your compressed JPEG images.  For PNG images, you can preserve copyright information.

You can instruct the API to save your optimized images in a variety of places.  Keep them in the buckets at Amazon S3 or Google Cloud Storage.  When you do so, you can also set custom cache control and expire headers.

Perfect Image Resizing

The API can not only optimize your images. but it can resize them too.  Just upload the original once.  Then you can generate whatever image sizes you need.  When you resize, the new image will also include correct gamma scaling, bicubic transparency edge correction and image sharpening.

When resizing images, API  also has the ability to crop away the parts that are visually less interesting.


You only pay for what you use.  The first 500 compressions each month are free.  You are only billed if you compress more than 500 images in a month.  Here are the very reasonable prices for images uploaded with API:


NEXT 9500 IMAGE COMPRESSIONS:  $0.009 per image

AFTER 10,000 IMAGE COMPRESSIONS:  $0.002 per image

If you reach your limit, API will return an error message that reads as follows:  “Your monthly limit has been exceeded.  Upgrade your account by entering your payment details on your WordPress and API dashboard.”

If you wish to disable using paid compressions, you are able to limit your account to free compressions at any time.  Just make the change on your account page.

Corporate Subscription

You can get special subscription plans for corporate use.  These have fixed fees, a fair usage policy, priority support and an optional yearly bank payment.

Third Party

You are offered many add-ons created by third-party companies and developers.  If you use one of these apps and need support, contact the add-on director.

There is a list of 36 modules or plugins that can be used with tinyPNG.  Most of them are free, though a few do charge a fee.  These modules are listed on tinyPNG’s site under four categories:  Content Management, Desktop, Development, and eCommerce.panda chewing bamboo leaves

The site includes a spot where you can enter your URL and your page will be analyzed.  As I use the plugin “Smush”, I was curious to see what response I’d get.  I entered my URL and tinyPNG’s panda said, “Wow!  You sure know how to compress your webpage.  Panda is very impressed with your current compression.  Seems like Panda can rest easy for now.”

That message pleased me, as it means my plugin is doing a good job.


One of the cheapest tools on the market

You don’t have to buy an upgrade if you don’t want to

A very efficient website:  You don’t have to download apps or software to use

The drag & drop system makes it easy to use

The effects are nearly invisible though the image is significantly compressed

Only widely supported format that can store partially transparent images


Some users report that JPEG results are not as good, as tinyPNG doesn’t really reduce their size much

There are limits on the free platform; to get more options you need to upgrade to Pro

You need to pay for purchase if you intend to use it on a really large scale.

You can only compress 10 images at a time in the free version

If you have spotty internet it could be a problem


I am quite impressed with this tool.  I used it before adding the Smush plugin, but since I had over 600 images on my site, I thought Smush would be easier; it did all the images that were already on there.  I know of one person in our group who uses both tinyPNG and Smush, because he feels it compresses his images still further.

This website furnishes an excellent tool for us to use to create optimum sizes for our images.  They definitely offer a service.  You can upgrade but you can also use the tool for free and your images will benefit greatly from the compression.

TinyPNG is not one of those sites out to get your money.  In fact, they have a “donate” heading if you want to help add to their research funds.

My overall ranking for this website is 4.7 out of a possible 5.

If you are looking for a place to build a website on which you can use this tool to compress your images, look at this review of the company I have chosen.  I believe it’s the best one out there.

  1. Nice review of TinyPNG Fran:)
    I also happen to use Optimizilla, which is my personal favorite.

    Others swear by Kraken, but I haven’t use this.

    Keep writing great reviews, you are doing great!

    • I have not tried Kraken or Optimizilla, though I did use TinyPng for a short time before getting Smush. It was a very helpful tool. I do like the plugin, however, because now images are automatically resized for me.
