I miss an other Solution here  2021   I use FileList to interact with file input  Since there is no way to create a FileList object  I use DataTransfer  that brings clean FilleList with it  I reset it with    file input files new DataTransfer   files    In my case this perfectly fits  since I interact only via FileList with my encapsulated file input element

The jQuery solution that  dhaval-marthak posted in the comments obviously works  but if you look at the actual jQuery call it s pretty easy to see what jQuery is doing  just setting the value attribute to an empty string  So in  pure  JavaScript it would be   document getElementById  uploadCaptureInputFile   value

Resetting a file upload button is so easy using pure JavaScript   There are few ways to do it  but the must straightforward way which is working well in many browser is changing the filed value to nothing  that way the upload filed gets reset  also try to use pure javascript rather than any framework  I created the code below  just check it out  ES6     x000D   x000D  function resetFile     x000D    const file   document querySelector   file    x000D    file value       x000D    x000D   lt input type  file  class  file    gt  x000D   lt button onclick  resetFile    gt Reset file lt  button gt  x000D   x000D   x000D

Particularly for Angular  document getElementById  uploadFile   value         Will work  But if you use Angular It will say   Property  value  does not exist on type  HTMLElement  any   document getElementById   returns the type HTMLElement which does not contain a value property  So  cast it into HTMLInputElement    lt HTMLInputElement gt document getElementById  uploadFile    value         EXTRA  -  However  we should not use DOM manipulation  document xyz    in angular   To do that angular has provided  VIewChild   ViewChildren  etc which are document querySelector    document queryselectorAll   respectively   Even I haven t read it  Better to follows expert s blogs  Go through this link1  link2

Another solution  without selecting HTML DOM elements    If you added  change  event listener on that input  then in javascript code you can call  for some specified conditions     event target value         For example in HTML    lt input type  file  onChange  onChangeFunction event   gt    And in javascript   onChangeFunction event      let fileList   event target files    let file   fileList 0     let extension   file name match     lt      w   g  0  toLowerCase       assuming that this file has any extension    if  extension      jpg         alert  Good file extension           else       event target value           alert  Wrong file extension  File input is cleared
