+# FileSizeFromBase64.NET
+
+A .NET Standard 2.1 project containing a single method to get file size from base64 string. The base64 string can contain MIME-type or not. Paddings are also supported in the decoding process, you can define whether the paddings rules should be applied or not.
+## Usage
+
+```csharp
+using FileSizeFromBase64.NET;
+
+// File hello-world.txt => Size = 13 Bytes, Content: Hello world !
+var base64String = "data:text/plain;base64,SGVsbG8gd29ybGQgIQ==";
+
+var fileSize = FileSizeHelpers.GetFileSizeFromBase64String(base64String, true);
+
+var fileSizeInKB = FileSizeHelpers.GetFileSizeFromBase64String(base64String, true, UnitsOfMeasurement.KiloByte);
+
+var fileSizeInMB = FileSizeHelpers.GetFileSizeFromBase64String(base64String, true, UnitsOfMeasurement.MegaByte);
+```
+
+## Parameters
