$d = compress($compressThisImg, $fileName, 80) Īnd this is the function that does compressing: //Function to compress an imageįunction compress($source, $destination, $quality) Base64 file and image size calculator Base64 WTF Each Base64 digit represents exactly 6 bits of data. $success = file_put_contents($filePath, $data) $filePath = 'foldername/'.'img'.$upAt.$extension $img = str_replace('data:image/jpeg base64,', '', $base64Img)
#Base64 encoding reduce size series#
Base64 encoding takes each byte of binary data (a series of 0s and/or a series of on and/or off' signals) and represents it with four characters. If (strpos($base64Img, 'data:image/jpeg base64') != false) For this to happen, they need to reduce the page size as much as possible. $img = str_replace('data:image/gif base64,', '', $base64Img) If (strpos($base64Img, 'data:image/gif base64') != false) $img = str_replace('data:image/png base64,', '', $base64Img) Finally, PHPs default buffer size is 8192 bytes - enough for 143 MIME lines. If (strpos($base64Img, 'data:image/png base64') != false) Base64-encoded data takes about 33 more space than the original data. This is the function that converts the string to an image. One for converting base64 string to image and other one for compressing it. But sometimes the images uploaded by the users can be of very large size, so I'm trying to compress them from backend and this part failed miserably. Image can be of any format- png,gif or jpeg. reduce file size in base64String Forums 4.0 Msdn en-US en 1033 Msdn. Leaving out these null values reduces our JSON data size to 166.8kB or 92.1 of the original data size. In our mock data, we set 50 of the phone numbers, and 30 of the email addresses, as empty. I get images as base64 encoded string front end and I have to decode them and save them as images in server. This leaves the initialization of empty values to each JSON processing library and reduces the JSON data size.
