The probability of occurrence is P(A) = 0.4, P(B)= 0.1, P(C) = 0.2 and P(D) = 0.3. The Huffman code is; A = 0 B = 111 C = 110 D = 10; A = 0 B = 11 C = 10 D = 111; A = 0 B = 111 C = 11 D = 101.

WebP is an image format employing both lossy and lossless compression. It is currently developed by Google, based on technology acquired with the purchase of On2 Technologies.

WebP's lossy compression algorithm is based on the intra-frame coding of the VP8 video format and the Resource Interchange File Format (RIFF) as a container format. As such, it is a block-based transformation scheme with eight bits of color depth and a luminance-chrominance model with chroma subsampling by a ratio of 1:2 (YCbCr 4:2:0).

The side length of WebP images is limited to 16383 pixels.

Movavi pdf editor 3 0 12. WebP's lossless compression uses advanced techniques such as dedicated entropy codes for different color channels, exploiting 2D locality of backward reference distances and a color cache of recently used colors. This complements basic techniques such as dictionary coding, Huffman coding and color indexing transform.

In this post, we've collected seven great online image optimizer tools that let you compress JPG, PNG, and GIF files right from your web browser.

Seven best online image optimizer tools tested and compared

Online image optimizer tools help you compress images or change file type without perceptible loss in quality.

To give you an idea of how much compression is possible, we put some online image optimizer tools to the test. Working with two images – one JPG (file size 238 KB approx) and another PNG (118 KB approx) – here's what we found:

Now, let's dig into the tools in more detail…

1. JPEG Optimizer

JPEG Optimizer is one of the first solutions to check out if all you need is to compress JPEG images.

Most of us should be fine with the default compression of 65, though the website can compress images anywhere between 0-99. Using just the default setting, I was able to cut down the file size by 66%.

If you wish, you can also view EXIF data (time, date and camera make) and resize your images. And then go on to add effects like captions, borders or shadows. Once the tool compresses the image, you can download it and use it anywhere you need.

2. Kraken

Kraken gives you a choice of compression modes:

• Lossless – zero drop in quality.
• Lossy – a small drop in quality, but cuts down image file size by almost 90%.

The lossy images will work just fine for most users, but professionals who wish to retain 100% visual information should opt for the lossless (e.g. photographers).

Kraken allows you to optimize not just JPEG, but PNG and GIFs as well. Files up to 1 MB are optimized for free, bigger files need you to go with their Pro package.

The Pro package starts at $5 per month and offers additional features too. It can pick up image files from multiple sources such as a list of URLs or a zip archive. That's not all, it can return the optimized images in a zip file, grab all the images from your website, organize them into folders, resize images, store them in the Kraken cloud and keep stats of your optimizations. A free plugin makes it all easy for WordPress users.

Compression:

👉 JPEG Image file saving – 11.32% (lossless), 70.05% (lossy)
👉 PNG Image file saving – 44.06% (lossless), 75.03% (lossy)

3. Tiny PNG

A trusted tool, Tiny PNG handles compression of both JPEG and PNG image formats with ease, letting you bulk upload up to 20 images in one go. Each file size can reach 5 MB. For larger files, you'll have to be a paying customer.

After compression, images can be downloaded to your computer or saved to Dropbox. Tiny PNG also makes it easy for WordPress users with a free plugin. To compare image optimization plugins for WordPress, look up our earlier post.

Compression:

👉 JPEG Image file saving: 32%
👉 PNG Image file saving: 75%

4. JPEG.io

To convert images of any format into JPEG, you can try JPEG.io. It handles more image types than most online image optimizer tools. To use it, you drag and upload your PNG, GIF, SVG or even PSD files to their website. First, the tool converts the images into JPEG, and then compresses them before returning the images to you.

The tool can also pick up image files from your Google Drive or Dropbox and return the optimized JPEG files to you in a zip archive.

Compression:

👉 JPEG Image file saving: 65%
👉 PNG Image file saving: 17%

5. ImageRecycle

If you've got images in multiple formats to optimize, you'll find ImageRecycle to be a safe bet. Not just PNG or JPEG, this tool supports even GIFs and PDFs. You can drag and drop your images on to the website and download the optimized images with a click.

One helpful thing about ImageRecycle is that it gives you a free report about your website with details of images that need optimization. Simply type in your website's URL to obtain this report.

To access features like URL or Page Optimizer, you'll have to opt for their one-time payment plans. You can take your pick from different price points at $10 (10,000 images), $20 (30,000 images), and $50 (100,000 images).

There's a 15 day free trial with a cap at 100 MB to help you make up your mind. Once you pay up, you can use your quota over a year on unlimited websites with any number of sub-accounts. A month's backup and restore is included. WordPress, Magento, and Joomla users can rely on extensions instead of visiting the website every time, while Shopify users get an exclusive app.

Compression:

👉 JPEG Image file saving: 48.97%
👉 PNG Image file saving: 78.57%

6. Compressor.io

If you're looking at high levels of compression that can save you hundreds of KB, take a close look at Compressor.io. It can reduce file sizes by close to 90%. It compresses JPEG and PNG images without loss of pixels, and lossy compression for other file types. However, the file size cannot exceed 10 MB.

A cool slider allows you to compare the original and optimized images side by side. You can download the file and save it to Google Drive or Dropbox.

Compression:

👉 JPEG Image file saving: 49%
👉 PNG Image file saving: 81%

7. Ezgif

Though the name might suggest otherwise, Ezgif is an all-purpose online image optimizer. You can use it to work on your GIFs, PNGs, and JPGs.

In the GIF department, Ezgif raises the bar to a new level. It lets you tinker about a lot with GIFs, including creating, resizing, cropping or optimizing them. You'll be able to create GIFs using JPEG, PNG and other images, and upload up to 2,000 files, though there's a cap on total size at 100MB.

Apart from that, the PNG and JPG optimization is pretty efficient as well. You can do some simple edits on your image before optimizing, too, like rotating, cropping, adding an overlay, and more. When it comes to the optimization itself, it's quite good.
