File Upload

A composable, accessible file-upload system supporting file selection, drag and drop, paste, validation, previews, upload progress, and file management. It exports a root component plus dropzone, trigger, list, item, metadata, preview, progress, delete, and clear primitives.

Installation

pnpm dlx shadcn@latest add https://diceui.com/r/radix-vega/file-upload.json

Usage

usage.tsx
import {  FileUpload,  FileUploadDropzone,  FileUploadTrigger,} from "@/components/ui/file-upload";<FileUpload>  <FileUploadDropzone>    <span>Drop files here</span>    <FileUploadTrigger>Browse files</FileUploadTrigger>  </FileUploadDropzone></FileUpload>
  • Use for forms that accept documents, images, media, archives, or other local files.
  • Use when users need drag-and-drop, clipboard paste, browse-button selection, previews, validation, or upload status feedback.
  • Use the controlled API when file state must be synchronized with form state or an external upload workflow.
  • Use the composable item primitives when the file list needs custom actions, metadata, or visual layouts.

Examples

Validated image upload with previews

Accepts images up to 5 MB, renders each selected file as an image preview, and shows a delete action.

validated-image-upload-with-previews.tsx
import {  FileUpload,  FileUploadDropzone,  FileUploadItem,  FileUploadItemDelete,  FileUploadItemMetadata,  FileUploadItemPreview,  FileUploadList,  FileUploadTrigger,} from "@/components/ui/file-upload";<FileUpload accept="image/*" maxSize={5 * 1024 * 1024} multiple>  <FileUploadDropzone>    <span>Drop images here</span>    <FileUploadTrigger>Select images</FileUploadTrigger>  </FileUploadDropzone>  <FileUploadList>    {files.map((file) => (      <FileUploadItem key={file.name} value={file}>        <FileUploadItemPreview />        <FileUploadItemMetadata />        <FileUploadItemDelete aria-label={`Remove ${file.name}`} />      </FileUploadItem>    ))}  </FileUploadList></FileUpload>

Controlled upload with progress

Uses controlled files and an asynchronous upload callback that reports progress, success, and errors.

controlled-upload-with-progress.tsx
import {  FileUpload,  FileUploadItem,  FileUploadItemMetadata,  FileUploadItemProgress,  FileUploadList,} from "@/components/ui/file-upload";<FileUpload  value={files}  onValueChange={setFiles}  onUpload={async (selectedFiles, { onProgress, onSuccess, onError }) => {    for (const file of selectedFiles) {      try {        await uploadFile(file, (progress) => onProgress(file, progress));        onSuccess(file);      } catch (error) {        onError(file, error instanceof Error ? error : new Error("Upload failed"));      }    }  }}>  <FileUploadList>    {files.map((file) => (      <FileUploadItem key={file.name} value={file}>        <FileUploadItemMetadata />        <FileUploadItemProgress variant="linear" />      </FileUploadItem>    ))}  </FileUploadList></FileUpload>

Custom validation and circular progress

Rejects files with a custom validator and displays circular progress inside each item.

custom-validation-and-circular-progress.tsx
import {  FileUpload,  FileUploadDropzone,  FileUploadItem,  FileUploadItemMetadata,  FileUploadItemPreview,  FileUploadItemProgress,  FileUploadList,} from "@/components/ui/file-upload";<FileUpload  multiple  onFileValidate={(file) =>    file.name.endsWith(".pdf") ? undefined : "Only PDF files are allowed"  }>  <FileUploadDropzone>Drop PDF files or paste them here</FileUploadDropzone>  <FileUploadList orientation="horizontal">    {files.map((file) => (      <FileUploadItem key={file.name} value={file}>        <FileUploadItemPreview />        <FileUploadItemMetadata size="sm" />        <FileUploadItemProgress variant="circular" size={32} />      </FileUploadItem>    ))}  </FileUploadList></FileUpload>

File picker with clear action

Provides a browse trigger and a clear-all button while limiting selection to three files.

file-picker-with-clear-action.tsx
import {  FileUpload,  FileUploadClear,  FileUploadList,  FileUploadTrigger,} from "@/components/ui/file-upload";<FileUpload maxFiles={3} multiple label="Attachments">  <FileUploadTrigger>Choose attachments</FileUploadTrigger>  <FileUploadList />  <FileUploadClear>Clear all</FileUploadClear></FileUpload>

Accessibility

  • The root generates an associated, visually hidden native file input with a configurable label, name, multiple, required, disabled, and accept attributes.
  • The dropzone uses role="region", keyboard focus, Enter and Space activation, aria-controls, aria-disabled, and aria-invalid; it also supports drag-and-drop and clipboard paste.
  • The trigger and clear controls are native buttons by default and expose aria-controls; provide accessible button text or an accessible name when using custom children.
  • Each item uses role="listitem", aria-setsize, aria-posinset, aria-labelledby, and aria-describedby with hidden status text describing ready, uploading, completed, or error states.
  • Progress indicators use role="progressbar" with aria-valuemin, aria-valuemax, aria-valuenow, aria-valuetext, and an accessible file-name label.
  • Provide an accessible name for delete controls, such as aria-label="Remove filename", because the component does not supply default visible text.
  • The default image preview uses the file name as its image alt text; custom render functions should preserve an appropriate accessible name.
