World's simplest online image base64 encoder for web developers and programmers. Just select your JPG, PNG, GIF, Webp, or BMP picture or drag & drop it in the form below, press the Convert to Base64 button, and you'll get a base-64 string of the image. Press a button - get base64. No ads, nonsense, or garbage Image to Byte array. Use this online image to Byte array tool for converting (monochromatic) bitmaps to data arrays (C++ style). You can use these arrays with programs for embedded systems with microcontrollers to output graphics on monochromatic LCD's or thermal printers (like Arduino with the Adafruit mini printer, which I needed this for) Image to byte array: <summary> method to convert an image object into a byte array, formatted in png file format, which provides lossless compression. this can be used together with the getimagefrombytearray() method to provide a kind of serialization deserialization. The image file is read into an image object using the fromfile function. For example, if you take a single 1kB image as a base64, you will save up to 600B transfer data and one request/response time. The image-to-base64 code is great speed up for example on gradient web images. If you want to decode image in Base64 format please use Base64 decoder This method uses the Image.FromStream method in the Image class to create a method from a memorystream which has been created using a byte array. The image thus created is returned in this method. The way I happen to use this method was to transport an image to a web service, by converting it to a byte array and vice-versa

To implement that first you need to create a memory stream from the byte[] array in your database and then use Image.FromStream If function image.isContinuous() returns true (which is usually the case) then it is already byte array. You can access it by calling image.data. If image.isContinuous() returns false (for example you worked with ROI of image), you will need to move the data. Easiest way will be by calling image.clone()
