To learn more about Base64, please visit Base64 Wikipedia page. It is also used to transmit binary files through channels that are not 8-bit clean, or without the need to worry about byte order issues. Base64 Decoder Online works well on Windows, MAC, Linux, Chrome, Firefox, Edge, and Safari.īase64 is numeral system of base-64 which uses 64 digit set and can be represented by 6 bits.īase64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation.īase64 is used to encode binary data in email messages and web pages, for example.Users can also convert base64 data File to Plain text by uploading the file.Click on the URL button, Enter URL and Submit. This tool allows loading the Base64 data URL, which loads base64 encoded text and decodes to human readable text.This tool saves your time and helps to decode base64 data.Note that, Base64 should not be confused with encryption or compression techniques. It converts the Base64 encoded data back to binary data. Base64 decoding is the inverse process of encoding. Base64 Decode is very unique tool to decode base64 data to plain text. The encoded data can be converted back to the original image or file at the receiver’s end using Base64 decoding.By looking at different methods to convert images to Base64 strings we now know the pros and cons of each approach.Base64 Decode is easy to use tool to decode base64 data to plain text. We converted a File, Blob,, and to DataURLs and we looked at how to convert a DataURL to a Base64 string. Audio, video, image or data file ID3 file information Bank identification number checker Base64 encoder and decoder. complete ) toDataURL (image ) // Wait for the image to load before converting else image. then ( ( blob ) => // If the image has already loaded, let's go! if (image. getElementById ( 'my-image' ) // Get the remote image as a Blob with the fetch API fetch (image. If the MIME type is incorrect the DataURL will be incorrect as well. Note that the MIME type returned by remote server in the Content-Type response header is reflected in the DataURL. If the image is located on a remote server the CORS configuration of the remote server must allow our local script to access the image. If our image is an element we can fetch the image src and convert that to a Base64 string.Īlternatively we can draw the image to a canvas and then convert the canvas to an image element, this would be useful if we’re looking for a specific image format. Convert to Base64 string const base64 = getBase64StringFromDataURL (dataURL ) Ĭonsole. log (dataURL ) // Logs data:image/jpeg base64,wL2dvYWwgbW9yZ. toDataURL ( 'image/jpeg', 0.5 ) Ĭonsole. getElementById ( 'my-canvas' ) // Convert canvas to dataURL and log to console const dataURL = canvas. When using 'image/jpeg' or 'image/webp' we can pass the image compression as the last argument, 0 means a lot of compression, 1 means no compression. īy default the canvas outputs to a lossless PNG, we can pass 'image/png', 'image/jpeg' or 'image/webp' to the toDataURL method to get a different format. log (dataURL ) // Logs data:image/png base64,wL2dvYWwgbW9yZ. If we have a that we want to turn into a Base64 string we can use toDataURL on the Canvas element. We’ll also use the FileReader API when converting an image tag to a Base64 string. When the image is a File object or Blob we can use the FileReader API please see this article on converting a file to base64 string or dataURL. const getBase64StringFromDataURL = ( dataURL ) =>ĭataURL. We’ll be converting images to DataURLs, we can use the function below to convert a DataURL to a Base64 string. In all examples below we assume we already have a, , File, or Blob object available. We look at converting a File object or Blob, a canvas element, and an image tag. In this short tutorial we explore 3 different JavaScript methods to convert an image into a Base64 string.
