I have come across many online toolboxes that allow you to do many things. on PDFs, images, audio files…but I have rarely seen ones as varied as 10015.io.
Indeed, this site which means TOOLS.io (tools) On leet speak offers a variety of tools in many areas: text, image, CSS, programming, colors, social networks and various…
Of course this site is 100% free and the cherry on the cake is that the few advertising inserts are relatively discreet.
The site has been designed with a very pleasant ergonomics and full of good ideas. Thus, it is possible to add a tool to favorites, which allows you to find it very easily when you need it.

Some examples of tools on 10015.io
As this site offers almost 50 different tools, I will not present them all, but here are a few examples.
You will find the tool List Randomizer which allows you to give a random order to a list and to remove any duplicates. Such a tool can be very practical for a draw or to designate the winners of a competition!


The tool Image Color Extractor allows you to upload an image to extract the correct dominant colors and obtain all the information related to these colors (HEX, RGB, HSLA, HTML color code).

With YouTube Thumbnail Grabber, you will be able to retrieve YouTube video thumbnail images for different resolutions by specifying only the video URL.

The tool Letter Counter allows you to obtain statistics relating to a text: number of sentences, number of words and number of letters.
Below the statistics, you will also find a table indicating whether the text in question is too long for different online services: tweet, Facebook comment, ideal length for referencing an article on Google... In short, a clever little reminder.

Each of these tools is really well designed and generally very easy to use. At the bottom of each page there is a description in English as well as a user guide.
Finally, if you use Chrome or Firefox browsers, the developer of the site has created extensions allowing you to have access to all the tools at all times!
