 $profileImage['name'] : null;
 if ($profileImage && $fileName) 
 try 


 $uploader = $this->_objectManager->create(
 'MagentoMediaStorageModelFileUploader',
 ['fileId' => 'proimage']

 $uploader->setFilesDispersion(true);
 $uploader->setAllowCreateFolders(true);
 /** @var MagentoFrameworkFilesystemDirectoryRead 
 $mediaDirectory */
 $mediaDirectory = $this->_objectManager-

 // Save news

 // Display success message
 $this->messageManager->addSuccess(__('The post has been 
 saved.'));

 // Check if 'Save and Continue'
 if ($this->getRequest()->getParam('back')) 
 $this->_redirect('*/*/edit', ['id' => $model->getId(), 
 '_current' => true]);
 return;
 

 // Go to grid page
 $this->_redirect('*/*/');
 return;
 catch (Exception $e) 
 $this->messageManager->addError($e->getMessage());
 

 $this->_getSession()->setFormData($formData);
 $this->_redirect('*/*/edit', ['id' => $postId]);
 
 

 

Add Below code in n _prepareForm() function inside

app/code/Vendor/Module/Block/Adminhtml/Module/Edit/Tab/Main.php

$fieldset->addField(
 'profile',
 'image',
 [
 'name' => 'profile',
 'label' => __('Profile Image'),
 'title' => __('Profile Image'),
 'required' => false,
 'disabled' => $isElementDisabled
 ]
);

app/code/Vendor/Module/Controller/Adminhtml/Index/Save.php

use MagentoFrameworkAppFilesystemDirectoryList;

$profileImage = $this->getRequest()->getFiles('profile');
$fileName = ($profileImage && array_key_exists('name', $profileImage)) ? $profileImage['name'] : null;
if ($profileImage && $fileName) 
 try 
 /** @var MagentoFrameworkObjectManagerInterface $uploader */
 $uploader = $this->_objectManager->create(
 'MagentoMediaStorageModelFileUploader',
 ['fileId' => 'profile']
 );
 $uploader->setAllowedExtensions(['jpg', 'jpeg', 'gif', 'png']);
 /** @var MagentoFrameworkImageAdapterAdapterInterface $imageAdapterFactory */
 $imageAdapterFactory = $this->_objectManager->get('MagentoFrameworkImageAdapterFactory')
 ->create();
 $uploader->setAllowRenameFiles(true);
 $uploader->setFilesDispersion(true);
 $uploader->setAllowCreateFolders(true);
 /** @var MagentoFrameworkFilesystemDirectoryRead $mediaDirectory */
 $mediaDirectory = $this->_objectManager->get('MagentoFrameworkFilesystem')
 ->getDirectoryRead(DirectoryList::MEDIA);

 $result = $uploader->save(
 $mediaDirectory
 ->getAbsolutePath('Modulename/Profile')
 );
 //$data['profile'] = 'Modulename/Profile/'. $result['file'];
 $model->setProfile('Modulename/Profile'.$result['file']); //Database field name
