Top 5 Online Image Optimizer Tools to Speed Up Your Blog
Images are integral part of any blog. They make blog posts more appealing. And SEO Optimized Images can drive huge traffic from search engines to your blog.
But at the same time, images can hurt your readership and SEO if they take much time to load. It is obvious that no one would love to read a slow loading blog. And Google considers site speed as a ranking factor.
Images play a great role in increasing or decreasing page load time. Previously I shared How to reduce image size using WP Smush.it Plugin. It’s still an awesome plugin for optimizing uploaded images of your blog.
But there’s a better way – Using an online image optimizer tool. It’s very easy to use. Just select an image and it will resize the image without losing quality. The best thing is, you can see the quality and size of the image before uploading it to your blog.
There’s a variety of image optimization tools that can help you to compress images without losing quality. In this post, I will be sharing 5 best Online image optimizer tools to speed up your blog.
Whether it’s JPEG, PNG or GIF, these tools can help you to optimize your images. These tools will compress images to improve your site speed.
I will show you the performance of these tools by compressing same image across the services. It will help you to choose the better one. But remember that a particular image cannot determine the optimum performance of a service.
I will be using this image for testing the performance of these tools.
TinyPNG is my personal favorite. I’ve been using this tool for a while. Most of the images of this blog are optimized by TinyPNG. This tool reduces the size of your PNG files by using smart lossy compression techniques. It also offers JPG compression, but I found that it works great for PNG only. The amazing thing about the tool is, it preserves image transparency.
Recently they launched TinyJPG for JPEG compression.
The service is fully free. It also offers plugins for Photoshop and WordPress.
Now let’s see how much it can compress the image.
This compression almost saved 80% without losing quality. Remember that compression varies from image to image. It doesn’t have any option to control the compression percentage. But it provides high-quality images with optimum compression.
You can compress up to 20 images at a time. Maximum file size is 5MB each.
2. DIY jpg
DIY jpg is a handy tool for JPEG optimization. This tool is specially created for bloggers and website owners to make their images web optimized. I often use this tool to optimize and compress jpg image files. This tool is created by the performance experts at DIYWPblog and DIYthemes.
Now let’s see how much it can save.
For below image, it saved 66 percentages and the image quality of the output is just fine. It doesn’t allow you to control the compression percentage.
You can upload 20 images at a time. Maximum upload size is 5mb. You can download all files as a ZIP format.
Compressnow is another free image compressor tool. It helps you to reduce the weight of images. The best thing about this tool is, it allows you to choose % of compression to get a result. It supports GIF, JPG, JPEG, PNG file. The downside of this tool is, it doesn’t preserve the image transparency.
Now let’s see how it works.
The below image was made with 20% compression and the output was quite OK. The image shrunk from 491 KB to 46KB which is really impressive. However, it gives the flexibility to set the compression percentage.
You can upload 10 images at 3MB max each at a time. For single file, maximum upload size is 9MB.
If you want to compress other formats in addition to PNG or JPEG, then Compressor.io is for you. It works with JPEG, PNG, GIF & SVG. This powerful online tool reduces the size of images and photo whilst maintaining a high quality. It has two types of compression – Lossy and Lossless.
I’ve tried a PNG file on this tool and the result was fine. It almost saved 78% and image quality was great. I tried both lossy and lossless compression, but I didn’t find any noticeable difference.
You can compress one file at a time and max file size is 10MB.
As its name suggests, ImageOptimizer is an online image optimizer service that resize, compress and optimize image files. It’s free and it has a desktop version. It offers different compression levels – best quality, high quality, normal, small file size, very small file size, minimum filesize.
I’ve tested an image on normal quality level. And the result was not so impressive. It shrunk the image from 491KB to 184KB. The output was just fine.
It allows only one image to compress at a time.
Over to You
So these are some best online tools to optimize images. I mostly use TinyPNG and DIYjpg for image optimization. But it’s tough to declare one as the best tool, each of these tools works great on some level.
