Repair Base64
Quite often, users cannot decode Base64, because they got a malformed or invalid string. For example, this can happen if the source outputs an unexpected Base64 standard, the user copied unnecessary data, or something damaged the Base64 value. As a rule, such strings cannot be decoded without additional processing or human intervention, and because of this some inexperienced users mistakenly think that these strings are not decodable. Therefore, to help you decoding the undecodable, I developed a “repair tool” powered by some kind of magic, which is able to fix malformed Base64 and even inform you about detected errors. Of course, don’t wait for miracle, but don’t be surprised if it happens.
Please note that the repair tool may return many false positives and you should manually tidy up the results. If you get some weird results, please don’t judge me harshly. This tool can repair hundreds formats of poorly formatted Base64 values and in some cases it’s necessary to sacrifice accuracy in order to achieve good results. If you got wrong results, please send me your string and I’ll try to improve this tool.

Got this one from a hidden value in a website, doesn't look like text, and it's IMO too short to be audio or video
Maybe just used for binary validation of some sort...
If you have an idea... :)
BTW excellent work here :D
Thanks for your help
how do enter the base64 code into a html page do i use a <html> tag then base64 uri like this
<src="data:text/html;base64,PCFkb2N0eXBlIGh0bWw+D.........end it with" /> </html>or how ??? please advise ... thank you in advance for the prompt reply!!! EdYou need a valid opening tag that supports HTML embedding (
srcis just an attribute). So, to embed a Base64 encoded HTML into a web page you can use iframe, embed, or object.For example, in your case, the code should look something like this:
<iframe src="data:text/html;base64,PCFkb2N0e..."></iframe>What I wanted to accomplish is to base64 the whole completed html phpmail page and send it all as base64 .. is that possible with some other type of tag the <iframe> tag doesent seem to work... mail servers dont seem to see the <iframe> tag just like the CSS must be sent inline within the html for it to work.. please be so kind to advise... thank you in advance for you expert reply!!
The text i recieved it is from an application in c#.When i get this text which i think it is base64 and i try to create a pdf file. the file it is created but it is shows a white page.
Your string is not a Base64 value. It is just a binary source of your PDF file.

I got this one from a hidden part of a website.

This is my undecodable ID^, even with the repair tool it did not work. It was received from a weird header nikto found on a webpage.
I have the error ID: 6da3-f4cd-b1a3-8653-101c-2582-7a63-c344
I'm totally clueless, so would help getting an audio file from this! All best.
You have to extract the full data URI from your HTML file (it is included between two quotation marks
src="..."). Then you can obtain the audio file using the Base64 to Audio decoder.: 0a78-5b9c-6c7d-8dc2-9dd2-835d-0a11-2a3a My last phone and new one did content transfer
Thanks so much
I'm sorry for delay. Unfortunately, your string is neither a Base64 string nor any data format known to me. I recommend asking users on specialized smartphone forums and tell them some basic info about the file (name, size, location).

thank you
Your string is part of an HTML page that contains several audio files and images embedded via data URI. The Repair Tool is able to extract all valid Base64 strings and this is why I'm confused because of your comment. Could you explain please what the problem is?

I have a series of JSON files that I am getting from an API. They use this format and I want to know why it has the \, the carriage return and padding issues. Or most importantly how I can include a script to repair them for my project. I will have anywhere from 0-n items which I will iterate through, transform and display as a modal with text or something. Thanks for your help and generosity!

i have found this in a website and couldn't get rid of it,
really appreciate your efforts for people,
i will be very thankful to you if you could help me to decode it.
Thanks
Sorry for delay. Also, I' sorry for bad news, but your string is not Base64 encoded.
thank you for your assistance!
Your string is a .woff font file (Web Open Font Format). You can decode your Base64 string the Base64 to File decoder.
Your Base64 string is a corrupted PNG image. I'm sorry, but I don't think you can repair it.

Sorry I'm a tech neanderthal. This is page 1 of 29. I tried to send the file but it won't let me or I be an idiot.
It seems to be an email attachment that contains a PDF file. It cannot be decoded properly, because you provided only first bytes of your Base64 string. However, if you do not know where it comes from, I highly recommend not trying to open it, because it may be a phishing message or even worse, it may contain security exploits.
please help me with the code 5b48-752d-fd82-de4d-a1d3-287c-e394-0ddb

Your submission is a valid Base64 string. Unfortunately, it contains data unknown to me. Perhaps, it may contain the result of a cryptographic function. Therefore, to decrypt it, you need to know the passphrase and algorithm.
In any case, if this file is from an unknown source, I strongly do not recommend running or including it in PHP, because it may be a backdoor.
i appreciate it.
