Top 12 Best Image Compressor Websites to Optimize Image 2020

Best Image compressor Websites are the oxygen for bloggers because it helps them to optimize images for best performance. Also, Compressed images perform better than non-compressed images in the online world. Like if you upload a non-compressed and unoptimized image in a blog post then it more likely to not load faster which will also decrease the chance of getting high ranking. Apart from the online world, offices also required images in less volume like under 100KB or 20KB. Because having fewer volume images can increases the transfer rate between one place to another in both online and offline situations.

To compress images, there are 12 best image compressor websites that I personally tested and experienced. Those 12 online compressor websites provide the best compressing quality. This means the size of the image will get reduced without affecting the quality of the image. And compressing images through an online image optimizer is 3x better than compressing the image using image compressor software. So, here are the top 12 best Image Compressor Websites that can compress images efficiently:

1. TinyPNG

Best Image Compressor Websites

TinyPNG is a quality image compressor website and it pretty well compresses images to PNG optimized format. And the best part of TinyPNG is that it doesn’t reduce the quality of images. Means, you will not notice any reduction in quality after compressing your image with TinyPNG. Also, it has a plugin for Photoshop Mac and Windows version which helps to optimize images well. Like it helps in saving the editing image without additional steps and it does the compression to the images before saving, instant crop and resizes, worry-free Color Management, etc.

Moreover, if you are a blogger and use platform then TinyPNG has a plugin for your WordPress website which automatically optimizes images in a click. You don’t need to go to every image you uploaded on your WordPress website, use the TinyPNG plugin to optimize all the images at once.

The ability of TinyPNG is incomparable. However, it can compress images up to 20 at once and the maximum size of each image is 5Mb which is very good. You can also read, How to compress images instantly using TinyPNG.

2. Imagify

Best Image Compressor Websites

Imagify is known for its ability to compress images. It can compress images at the best possible quality without quality reduction. It has three modes for users to compress images; Normal, Aggressive and Ultra. And all these modes compresses images at a different level. Means, you can compress your image according to your needs like how a level of compression you want to apply to your image. In my opinion, if you want to compress an image that is extremely high in size then select the Ultra Mode, if an image is medium at volume and you just want to little reduce the volume then Aggressive mode is best. And I don’t suggest to use the Normal mode in Imagify because it doesn’t compress images well and leaves the images as it is.

The ability of Imagify is not as powerful as TinyPNG but it has modes that separate it from the rest of the online image optimizers. Imagify can compress image size up to 2Mb for free account users, it will get extended when you buy it any plan. And you can upload unlimited images at once to get the images compressed.

Moreover, in the free account, your uploaded image to Imagify will be available for 24 hours. This means if something happened wrong or the compressed image got deleted, you can re-download the compressed image from the Imagify cloud.

3. Compressnow

Best Image Compressor Websites

Compressnow is the one who lets the user decide to fix the final compressed image size and quality. Meaning, you can manually set the size and quality of the image in the Compressnow website before compressing the image. That is like some offline image optimizer software that let user pre-resize the image before compressing. Right? Compressnow does the same, a user can set the compression level at their choice before uploading and compressing the image. Even more, you can upload unlimited images at once to compress in Compressnow website.

And you can also download them all in once in a zip format. And use them by extracting the zip file with 7zip or WinRAR software. So, the Compressnow is the best image compression website that I have found and using this you can preset the compressed image file size which is a great deal. However, I have seen in some banks that require a digital photo under 20KB.

And for that purpose, you can use Compressnow to make any image under 20Kb. You don’t need any additional steps, just upload it on the Compressnow website, set the level of compression and press the compress now button to compress the image and download it.

So, if you are in a condition where you need an image under a specific size like 20Kb or 100Kb then simply use the Compressnow website to make that kind of image size.

4. Online Image Optimizer

Online Image Optimizer is a coded webpage that optimizes images by compressing them.

This online image optimizer is available only in the Beta version means the full and stable JPEG optimizer hasn’t released. But still works like a stable online image JPEG optimizer which allows compressing the image and resizing.

JPEG Optimizer allows users to set their own compression levels from 0-99 in number format. And the resizer has only one option to set which produces a rectangle image size and destroys the beauty of the image. And so, I don’t recommend resizing the image using JPEG optimizer but I do recommend to use its compression service if you really want to optimize your JPEG format image at best.

6. Optimizilla

Best Image Compressor Websites

Optimizilla uses a smart image optimization technique and lossy compression algorithm to optimize and compress the image at the best possible file size along with taking care of the quality of the image.

The only bad thing has is it doesn’t allow uploading multiple files at once which a very bad thing. Because sometimes users want to compress multiple files to compress the image at once to save time. But only allows uploading images one by one which consumes a good amount of time compared to other compressor websites.

Overall, nothing is bad except the image uploading limit in and it seems like the developers working on it and hopefully, it will be fixed soon in the future. And its really deserves the appreciation for its file size uploading limit. It allows users to upload image file size up to 10MB which is incomparable.
