Optimize Jpg

• open many image types including rare/scientific types
• save and optimize JPEG, GIF and PNG with a simple, clean user interface
• automatic optimization selects the most suitable format and parameters
• works in dual view: (original – optimized image) or single view (optimized image).
  automatic preview of resulting image
• in-place compare function (alternativelly display the original image over the optimized image to notice small pixel changes)
• compress files to desired filesize threshold
• fast processing (all is done in memory);
  see instant results including resulting filesize
• batch support (process multiple files at once)
• transparency handling options
• decide if you want to keep metadata (comments, IPTC, Adobe XMP, EXIF profiles, ICC profiles).
  Unsupported metadata is removed
• transfer metadata between image formats (destination format must support them)
• common tools: pan and zoom, rotate, flip
• basic image adjustments: brightness, contrast, gamma, invert
• visually reduce number of unique colors for PNG and GIF images in order to reduce filesize
  (two quantization methods are available: Xiaolin Wu and NeuQuant neural net)
• resize image by using well known resample filters (ex: Lanczos3, Catmull Rom, Bicubic, and others)
• out-of-the-box support for external PNG optimizers (optipng, pngout, etc)
• the compression and the results are comparable to those of commercial products, even higher.
• Adaptive logarithmic tone mapping algorithm (Drago) used for HDR images

Input image types

Optimize Jpeg

• common bitmap images as well as Adobe Photoshop PSD files
• popular HDR formats and RAW camera images
• rare/scientific types (up to 128 bpp, integer and floating point)

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:

Compress JPEG Images Online Select up to 20.jpg or.jpeg images from you device. Or drag files to the drop area. Wait for the compression to finish. Ready to optimize your images? Image File Type Options. There are three main file types we'll want to focus on for saving images optimized for the web: GIF, JPG and PNG. Each file type has its own strengths and weaknesses and it is very important to know and keep these in mind when saving an image. Working with JPGs. More than 1 billion JPEG and PNG images optimized and still counting! What does TinyJPG do? TinyJPG reduces the file size of your JPEG images. Every uploaded image is analyzed to apply the best possible JPEG encoding.

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.

👉 JPEG Image file saving – 66%

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.

Optimize Jpeg For Web

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.

Optimize Jpg Online

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.

Compression:

👉 JPEG Image file saving: 49%
👉 PNG Image file saving: 47%

Final thoughts on the best online image optimizer tools

According to our results, Kraken offers the highest compression for JPG images, while Compressor.io won out when it comes to PNG files. You can view a summary of our results one more time below:
