Image optimization plays a crucial role in loading speed of a website and many especially webmasters, bloggers out there want to shrink your picture to least possible size by removing unnecessary data or info that are packed in a file.
Best ways of compressing jpeg, png format pictures
Let’s see some of the free online tools first
Very simple that any one could try is uploading the pictures of any format ( if they are taken in digital SLR camera) to anyone of social media websites especially Facebook because after its uploaded its automatically being shrinked to best possible solutions and later on you could just download the entire album or one by one.
As the name its used for optimising PNG images losslessly, means no change in the image quality before and after upload.
Just drag and drop your files of any size with PNG format to the website and you can get highly shrinked one in no time.
You can further strip some more bytes by again uploading the shrinked one to the website and Tinypng will again strip out information. Continue till 0%.
Does this one support batch conversion?
- Yes, drop upto 20 is possible.
Are there any size limitations?
- Yes there is limit of 5MB for each file
Can I save to other online cloud space ?
- Yes, currently they support only DropBox
Its same as the later one but the only difference is, it support only JPG formats of maximum size 5MB, we have also tried this one and level of compression was good like their former service. Now you can now use anyone of their website to shrink both the formats which was not possible back in 2013.
Like the previous tool this one is quite handy with drag and drop interface for only jpeg formats. Moreover you will shown a side to side comparison with the quality of image. Even though you didn’t see much change in quality, try to zoom in you will see some loss in the quality but it won’t be a problem to many of us.
