Awesome share, I would +rep if I could. :)
This is the best, I have seen.
Thanks for posting here bro.
Hi!
Haha, thanks man, very cool program and very great source!
You deserve some green apples 😁 !
Wow that's great! Can I also use it with crypters?
would be cool to know how to use in crypters...
Mondo cool mate.Thank you for this.
nice work, looks good, probably wont use it myself, but seems like many others will

Crypt:
Code Function pixelator(ByVal a As String) As Image
a = Convert.ToBase64String(New System.Text.UTF8Encoding().GetBytes(CompressString(a)))
Dim imageholder As Bitmap
Dim autosize As Integer = System.Math.Sqrt(a.Count) + 2
imageholder = New Bitmap(autosize, autosize)
Dim G As Graphics = Graphics.FromImage(imageholder)
Dim fff As Integer = 0
While fff <= a.Count - 1
For Y = 1 To imageholder.Height - 1
For X = 1 To imageholder.Width - 1
If fff <= a.Count - 1 Then
imageholder.SetPixel(X, Y, Color.FromArgb(Convert.ToInt32(a.Chars(fff)), 0, 0))
fff = fff + 1
End If
Next X
Next Y
End While
Return imageholder
DeCrypt:
Code Function depixelator(ByVal a As Image) As String
Dim retrievestr As String = ""
Dim xmax As Integer
Dim ymax As Integer
xmax = a.Width - 1
ymax = a.Height - 1
For y = 1 To ymax
For x = 1 To xmax
With CType(a, Bitmap).GetPixel(x, y)
retrievestr = retrievestr & Convert.ToChar(.R)
End With
Next x
Next y
retrievestr = New System.Text.UTF8Encoding().GetString(Convert.FromBase64String(retrievestr.Replace(Convert.ToChar(0), "")))
retrievestr = DecompressString(retrievestr)
Return retrievestr
End Function
Needed Functions:
Code Public Shared Function CompressString(ByVal text As String) As String
Dim buffer__1 As Byte() = Encoding.UTF8.GetBytes(text)
Dim memoryStream = New IO.MemoryStream()
Using gZipStream = New IO.Compression.GZipStream(memoryStream, CompressionMode.Compress, True)
gZipStream.Write(buffer__1, 0, buffer__1.Length)
End Using
memoryStream.Position = 0
Dim compressedData = New Byte(memoryStream.Length - 1) {}
memoryStream.Read(compressedData, 0, compressedData.Length)
Dim gZipBuffer = New Byte(compressedData.Length + 3) {}
Buffer.BlockCopy(compressedData, 0, gZipBuffer, 4, compressedData.Length)
Buffer.BlockCopy(BitConverter.GetBytes(buffer__1.Length), 0, gZipBuffer, 0, 4)
Return Convert.ToBase64String(gZipBuffer)
End Function
Public Shared Function DecompressString(ByVal compressedText As String) As String
Dim gZipBuffer As Byte() = Convert.FromBase64String(compressedText)
Using memoryStream = New IO.MemoryStream()
Dim dataLength As Integer = BitConverter.ToInt32(gZipBuffer, 0)
memoryStream.Write(gZipBuffer, 4, gZipBuffer.Length - 4)
Dim buffer = New Byte(dataLength - 1) {}
memoryStream.Position = 0
Using gZipStream = New GZipStream(memoryStream, CompressionMode.Decompress)
gZipStream.Read(buffer, 0, buffer.Length)
End Using
Return Encoding.UTF8.GetString(buffer)
End Using
End Function
Simple Usage:
Code Crypt: PictureBox1.Image = pixelator(RichTextBox1.Text)
DeCrypt: RichTextBox1.Text = depixelator(PictureBox1.Image)

what program did you use to make
animated GIF picture ?
good one..
will be helpful..
I like this a lot, used something a long time ago to chat with my friends so no one can know what we were writing to each other. Nice times😁.
Bas mi se svidja sto si ovo uradio, svaka cas samo tako nastavi!😉
Thats so cool
Thanks for the share
Nice app, thank you!
toshort lol
thanks, it is very interesting.
Thanks for sharing
Hey THanX for this source !!
Hiding Data In Pics = Stegnography :)
Nice Work
Keep IT UP bro
