As said in Tatu Ulmanen s answer using the follow script will do the job     input checkbox   removeAttr  checked      But  as Blakomen s comment said  after version 1 6 it s better to use jQuery prop   instead     Note that in jQuery v1 6 and higher  you should be using    prop  checked   false  instead for greater cross-browser   compatibility      input checkbox   prop  checked   false     Be careful when using jQuery each   it may cause performance issues   also  avoid jQuery find   in those case  Use each instead      input type checkbox    each function             this  prop  checked   false

I have used this before      input type checkbox    prop  checked   false     seems that  attr and  removeAttr doesn t work for some situations   edit  Note that in jQuery v1 6 and higher  you should be using  prop  checked   false  instead for greater cross-browser compatibility - see https   api jquery com prop  Comment here  How to reset all checkboxes using jQuery or pure JS

The above answer did not work for me -  The following worked     input type checkbox    each function               this checked   false          This makes sure all the checkboxes are unchecked

If you want to use form s reset feature  you d better to use this      input type checkbox    prop  checked  true      OR     input type checkbox    prop  checked  false     Looks like removeAttr   can not be reset by form reset

You can be selective of what div or part of your page can have checkboxes checked and which don t  I came across the scenario where I have two forms in my page and one have prefilled values for update  and other need to be filled fresh       newFormId input type checkbox    attr  checked  false     this will make only checkboxes in form with id newFormId as unchecked

In some cases the checkbox may be selected by default  If you want to restore default selection rather than set as unselected  compare the defaultChecked property       checkbox   each function i item            this checked   item defaultChecked
