Here in this post, I will tell you 8 best online image compression tools to compress and optimise Png and Jpeg images.

Images and videos are the best ways to maintain readers interest, so it is necessary to use them in your posts. But it is also important to reduce the size of your images before uploading it to your website.

You should always keep your images compressed to prevent high loading time. Decreasing website loading time will help you to rank higher in search engines.

Compressing Images with these tools will not reduce the visual quality of your images. The size of the images will be reduced more or less depending on the tool and image.

1. Optimizilla

This is one of the most popular online image compressors.

Optimizilla can compress png and Jpeg images by best optimizing techniques. It can compress up to 20 images at a time. The most important thing which I like about Optimizilla is its setting to increase or decrease colors.

Click on the setting tab on the compressed image and you can choose the number of colors on your Image. Reduce the number of colors and the image size will be reduced more.

Optimizilla gives you the option to compare the compressed image with the original one. This will be helpful to check whether the compressed image is up to the quality or not.

Both image compression tools allow 20 images to be compressed at a time. They also have the option to save your compressed images to Dropbox.

Bonus tip:

You can compress the image by one image compression tool and then upload it again to another. It will compress image more, without reducing the quality.

Using this trick I compressed my 549.45kb image to 99kb without reducing the quality. I compressed the image by Imagerecycle and again uploaded to TinyJpeg which compressed the image 27% more.

Wrapping Up things:

These image compression tools can reduce the size of your image without affecting the quality which we can observe.

That means if you will zoom the compressed image then you may spot the difference. But the difference is negligible as compared to reduced size.

Never increase the compression level to greater value because the image quality will be highly affected.
