Change default text in input type=“file”?

I want to change default text on button that is "Choose File" when we use input="file".

How can I do this? Also as you can see in image button is on left side of text. How can I put it on right side of text?

Each browser has it's own rendition of the control and as such you can't change either the text or the orientation of the control.

There are some "kind of" hacks you may want to try if you want an html/css solution rather than a Flash or silverlightsolution.

Personally, because most users stick to their browser of choice, and therefore are probably used to seeing the control in the default rendition, they'd probably get confused if they saw something different (depending on the types of users you're dealing with).

Use "for" attribute of label for input.

<div>
  <label for="files" class="btn">Select Image</label>
  <input id="files" style="visibility:hidden;" type="file">
</div>

Below is the code to fetch name of the uploaded file

$("#files").change(function() {
  filename = this.files[0].name
  console.log(filename);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
      <label for="files" class="btn">Select Image</label>
      <input id="files" style="visibility:hidden;" type="file">
    </div>

This might help someone in the future, you can style the label for the input as you like and put anything you want inside it and hide the input with display none.

It works perfectly on cordova with iOS

<link href="https://cdnjs.cloudflare.com/ajax/libs/ratchet/2.0.2/css/ratchet.css" rel="stylesheet"/>
<label for="imageUpload" class="btn btn-primary btn-block btn-outlined">Seleccionar imagenes</label>
<input type="file" id="imageUpload" accept="image/*" style="display: none">

I think this is what you want:

<!DOCTYPE html>
<html>

<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JS Bin</title>
</head>

<body>
  <button style="display:block;width:120px; height:30px;" onclick="document.getElementById('getFile').click()">Your text here</button>
  <input type='file' id="getFile" style="display:none">
</body>

</html>

It is not possible. Otherwise you may need to use Silverlight or Flash upload control.

Here how you can do it:

jQuery:

$(function() {
  $("#labelfile").click(function() {
    $("#imageupl").trigger('click');
  });
})

css

.file {
  position: absolute;
  clip: rect(0px, 0px, 0px, 0px);
  display: block;
}
.labelfile {
  color: #333;
  background-color: #fff;
  display: inline-block;
  margin-bottom: 0;
  font-weight: 400;
  text-align: center;
  vertical-align: middle;
  cursor: pointer;
  background-image: none;
  white-space: nowrap;
  padding: 6px 8px;
  font-size: 14px;
  line-height: 1.42857143;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

HTML code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div style="margin-top:4px;">
  <input name="imageupl" type="file" id="imageupl" class="file" />
  <label class="labelfile" id="labelfile"><i class="icon-download-alt"></i> Browse File</label>
</div>

Using Bootstrap you can do this thing like below code.

<!DOCTYPE html>
<html lang="en">
<head>
<style>

.btn-file {
  position: relative;
  overflow: hidden;
}
.btn-file input[type=file] {
    position: absolute;
    top: 0;
    right: 0;
    min-width: 100%;
    min-height: 100%;
    font-size: 100px;
    text-align: right;
    filter: alpha(opacity=0);
    opacity: 0;
    outline: none;
    background: white;
    cursor: inherit;
    display: block;
}
</style>

</body>
</html>

I made a script and published it at GitHub: get selectFile.js Easy to use, feel free to clone.

HTML

<input type=file hidden id=choose name=choose>
<input type=button onClick=getFile.simulate() value=getFile>
<label id=selected>Nothing selected</label>

var getFile = new selectFile;
getFile.targets('choose','selected');

Update 2017:

I have done research on how this could be achieved. And the best explanation/tutorial is here: https://tympanus.net/codrops/2015/09/15/styling-customizing-file-inputs-smart-way/

I'll write summary here just in case it becomes unavailable. So you should have HTML:

<input type="file" name="file" id="file" class="inputfile" />
<label for="file">Choose a file</label>

Then hide the input with CSS:

.inputfile {
width: 0.1px;
height: 0.1px;
opacity: 0;
overflow: hidden;
position: absolute;
z-index: -1;}

Then style the label:

.inputfile + label {
font-size: 1.25em;
font-weight: 700;
color: white;
background-color: black;
display: inline-block;
}

Then optionally you can add JS to display the name of the file:

var inputs = document.querySelectorAll( '.inputfile' );
Array.prototype.forEach.call( inputs, function( input )
{
var label    = input.nextElementSibling,
    labelVal = label.innerHTML;

input.addEventListener( 'change', function( e )
{
    var fileName = '';
    if( this.files && this.files.length > 1 )
        fileName = ( this.getAttribute( 'data-multiple-caption' ) || '' ).replace( '{count}', this.files.length );
    else
        fileName = e.target.value.split( '\\' ).pop();

    if( fileName )
        label.querySelector( 'span' ).innerHTML = fileName;
    else
        label.innerHTML = labelVal;
});
});

But really just read the tutorial and download the demo, it's really good.

I'd use a button to trigger the input:

<button onclick="document.getElementById('fileUpload').click()">Open from File...</button>
<input type="file" id="fileUpload" name="files" style="display:none" />

Quick and clean.

This should work:

input.className::-webkit-file-upload-button { style content.. }

Let me add a hack I used. I wanted to have a section that allowed you to drag and drop files, and I wanted that drag and drop section to be clickable along with the original upload button.

Here is how it looked like when I was done (minus the drag and drop ability, there are plenty of tutorials on how to do that).

And then I actually created a series of blog posts that are mainly about file upload buttons.

Ok so very simple pure css way of creating your custom input file.

Use labels, but as you know from previous answers, label doesn't invoke onclick function in firefox, may be a bug but doesn't matter with the following.

<label for="file"  class="custom-file-input"><input type="file"  name="file" class="custom-file-input"></input></label>

What you do is style the label to look how you want it to

    .custom-file-input {
        color: transparent;/* This is to take away the browser text for file uploading*/
        /* Carry on with the style you want */
        background: url(../img/doc-o.png);
        background-size: 100%;
        position: absolute;
        width: 200px;
        height: 200px;
        cursor: pointer;
        top: 10%;
        right: 15%;
    }

now simply hide the actual input button, but you cant set it to to visability: hidden

So make in invisible by setting opacity: 0;

input.custom-file-input {
    opacity: 0;
    position: absolute;/*set position to be exactly over your input*/
    left: 0;
    top: 0;
}

now as you might have noticed i have the same class on my label as i do my input field, that is because i want the to both have the same styling, thus where ever you click on the label, you are actually clicking on the invisible input field.

You can use this approach, it works even if a lot of files inputs.

const fileBlocks = document.querySelectorAll('.file-block')
const buttons = document.querySelectorAll('.btn-select-file')

;[...buttons].forEach(function (btn) {
  btn.onclick = function () {
    btn.parentElement.querySelector('input[type="file"]').click()
  }
})

;[...fileBlocks].forEach(function (block) {
  block.querySelector('input[type="file"]').onchange = function () {
    const filename = this.files[0].name

    block.querySelector('.btn-select-file').textContent = 'File selected: ' + filename
  }
})

.btn-select-file {
  border-radius: 20px;
}

input[type="file"] {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="file-block">
  <button class="btn-select-file">Select Image 1</button>
  <input type="file">
</div>
<br>
<div class="file-block">
  <button class="btn-select-file">Select Image 2</button>
  <input type="file">
</div>

<button class="styleClass" onclick="document.getElementById('getFile').click()">Your text here</button>
<input type='file' id="getFile" style="display:none">

This is still the best so far
