This code was written for me by @Jaafar Tribak long ago.
I use it to compress larger images in a folder
Now I want to tweak it a little bi:

This is how I am calling the code to work:
Code:
Sub CompressLargeImages()
    Dim oFSO As Object, oFolder As Object, oFile As Object
    Dim sFolderPath$, sResizedFiles() As String, i As Long
    
    Const NEW_REDUCED_FILE_SIZE = 35000
    
    With Application

        sFolderPath = ThisWorkbook.Path & .PathSeparator & "PASSPORT PICTURES" & .PathSeparator

        Set oFSO = CreateObject("Scripting.FileSystemObject")
        Set oFolder = oFSO.GetFolder(sFolderPath)
        For Each oFile In oFolder.Files
            If InStr(1, "jpg jpeg png gif iff bmp svg", oFSO.GetExtensionName(oFile.Path), vbTextCompare) Then
                If oFile.Size >= NEW_REDUCED_FILE_SIZE Then
                    Call ResizeImageFile(SourceFile:=sFolderPath & .PathSeparator & oFile.Name, NewFileSize:=NEW_REDUCED_FILE_SIZE)
                    ReDim Preserve sResizedFiles(i)
                    sResizedFiles(i) = sFolderPath & .PathSeparator & oFile.Name
                    i = i + 1
                End If
            End If
        Next
    End With
End Sub

what I want to do now is to be able to use file explorer to browse for an image and compress it.
I have not been able to figure it out yet
Could someone please help me fix it?
 

Excel Facts

Ambidextrous Undo
Undo last command with Ctrl+Z or Alt+Backspace. If you use the Undo icon in the QAT, open the drop-down arrow to undo up to 100 steps.
You shouldn't need the scripting object if you use the msoFileDialogFilePicker to return the path to the chosen file. I suppose you could eliminate some of that code by
- eliminating the loop (at least the folder loop - you might want to multi select and loop over chosen files)
- restricting the type of displayed file via that Filter property of the dialog. That would enable you to show only files by type and extension.

Okay
Thanks
Here I wanna select just one item

Can you please point it out for me by adjusting the above code for me?

I would say that the code you'd need to integrate would look like
VBA Code:
Set fd = Application.FileDialog(msoFileDialogFilePicker)
With fd
   .Title = "Select File"
   .AllowMultiSelect = False
   .InitialFileName = ThisWorkbook.Path
   '.Filters.Add "EXCEL", "*.xlsm", 1
   .Filters.Add "Images", "*.jpg; *.jpeg; *.png; *.gif; *.bmp; *.tiff; *.svg", 1
End With

If fd.Show Then
     sFolderPath = fd.SelectedItems(1)
'rest of image handling code here

End If
One pic type in the code is "iff" - maybe that should be tiff?
It looks like integrating it would be a bit of a task - hoping you can manage it.

To do what you want, you can use the built-in file dialog picker function as suggested by Micron, to choose the image file to be compressed.

Usage example:
The following implementation will create a compressed copy of the chosen image file in the same directory down to roughly 35000 bytes.
If you omit the optional 3rd DestinationFileCopy argument, the original file will be over written !!

VBA Code:
Sub Test()
    Const NEW_REDUCED_FILE_SIZE = 35000 'bytes   '<<== change compressed size as needed.
    Dim fd As FileDialog, sFilePathName As String, sDestFile As String
 
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    With fd
        .Title = "Select File"
        .AllowMultiSelect = False
        .InitialFileName = ThisWorkbook.Path
        .Filters.Add "Images", "*.jpg; *.jpeg; *.png; *.gif; *.bmp; *.tiff; *.svg", 1
    End With
    If fd.Show Then
        sFilePathName = fd.SelectedItems(1)
        If FileLen(sFilePathName) >= NEW_REDUCED_FILE_SIZE Then
            sDestFile = Left(sFilePathName, InStrRev(sFilePathName, Application.PathSeparator)) & "Compressed " & Dir(sFilePathName)
            Call ResizeImageFile(SourceFile:=sFilePathName, NewFileSize:=NEW_REDUCED_FILE_SIZE, DestinationFileCopy:=sDestFile)
            MsgBox "Done."
        End If
    End If
End Sub


Edit:
Just for the record. This is image size reduction, not really image compression.

Okay thanks @Jaafar Tribak
I was about to post tweak I made to get it working through the loop

My question is that with the new api will the previous usage still hold?

That is resizing all images in the folder

This is how I got it working before your new update:
Code:
Sub TestCompress()
   Dim fd As Object, sFile$
   Dim strFolderPath, i&, oSubFolder
   Dim oFSO As Object, oFolder As Object, oFile As Object
   Dim sFolderPath$, sResizedFiles() As String
   Const NEW_REDUCED_FILE_SIZE = 35000
   
   Set oFSO = CreateObject("Scripting.FileSystemObject")
   Set fd = Application.FileDialog(msoFileDialogFilePicker)
   
   With fd
       .Title = "Select File"
       .AllowMultiSelect = False
       .InitialFileName = ThisWorkbook.Path
       .Filters.Add "Images", "*.jpg; *.jpeg; *.png; *.gif; *.tiff; *.bmp; *.svg", 1
   End With
   
   If fd.Show Then
       sFile = fd.SelectedItems(1)
       sFolderPath = Left(sFile, InStrRev(sFile, "\"))
       With Application
           Set oFolder = oFSO.GetFolder(sFolderPath)
           For Each oFile In oFolder.Files
               If sFile = oFile Then
                   If oFile.Size >= NEW_REDUCED_FILE_SIZEThen
                       Call ResizeImageFile(SourceFile:=sFolderPath & .PathSeparator & oFile.Name, NewFileSize:=NEW_REDUCED_FILE_SIZE)
                       ReDim Preserve sResizedFiles(i)
                       sResizedFiles(i) = sFolderPath & .PathSeparator& oFile.Name
                       i = i + 1
                   End If
               End If
           Next oFile
       End With
   End If
 
   Set oFSO = Nothing
   Call ClearExcelFolder
End Sub
