Base64 to PDF
Convert Base64 to PDF online using a free decoding tool which allows you to decode Base64 as PDF and display it directly in the browser. In addition, you will receive some basic information about this PDF (MIME type, extension, size). And, of course, you will have a special link to download the PDF to your device. If you are looking for the reverse process, check PDF to Base64.
Important notes about the decoder
The “Base64 to PDF” converter will force the decoding result to be displayed as a PDF file, even if it is a different file type. Therefore, if you are not sure that your Base64 string is a PDF, use the Base64 to file converter since it is capable of displaying various file types. In any case, feel free to give it a try, since this converter will inform you if something is wrong.

I hope you enjoy this discussion. In any case, I ask you to join it.
Thank you for your message. I fixed the downloading feature for MSIE. By the way, to preview PDF files on MSIE you should install and enable a PDF Reader add-on.
file_put_contents()to write binary into file. If you need an example, just let me know.Do you know why?
Do you know do to convert a base64 string into a pdf, in python ?
Thanks a lot for your help and great concept!

data:application/pdf;base64,prefix from your string before passing it to thebase64_decodefunction.data:application/pdf;base64,prefix from base64 encoded string before passing it to the base64_decode function?str_replace('data:application/pdf;base64,', '', $base64_data_uri)Thank You

I'm able to decode it, but I get a malformed document.
Can you provide please the snippet you are using? Also, are you sure your Base64 string is a valid string? If not, please validate it using Base64 Validator.
Can you help?
[UPDATED: ]
I just tried again and this time it worked. I assume now it is related to the file size, the result is 10.3MB. Thank you for a great utility!
I have the problem, that i decode my base64 string and write it in a file. During the decode no error occured and it works fine. To decode my base64 string on this website works fine too. I can also download my pdf file and open it in browsers like chrome, morzilla and on my mac. But if i want to open the file with Adobe Acrobat Reader an error occured. Adobe throws the error that the file is damaged and it cant be repaired.
Do you know a solution?
Thanks

chorus pro expect a pdf file be compress zip then convert in base64. Have you a proceed to do that. Thanks.
Thanks.
I cannot reproduce this issue on Chrome 81.0.4044.113 and Firefox 76.0.1. Can you please tell me what is your browser and OS version? Also I would like to know if there appears any errors on Browser Console while are you trying to click the "Download" link.
Chrome Version 81.0.4044.138
I am seeing it flash in red - your browser cannot display the file application.pdf . Does that prevent the download?
Console has a warning:
adsbygoogle.js:195 The PerformanceObserver does not support buffered flag with the entryTypes argument.
Nk @ adsbygoogle.js:195
l.fa @ adsbygoogle.js:52
tf @ adsbygoogle.js:60
Mk @ adsbygoogle.js:192
(anonymous) @ adsbygoogle.js:201
(anonymous) @ adsbygoogle.js:201
However, this bug should not overlap with your issue, because the "download" function works the same way on all pages. This is why I think your issue is somehow related to your Base64 value. To find out for sure, try to decode the Base64 value from that page using the decoder on this page and check if you can preview/download it.
By the way, if your PDF does not contain any sensitive information, you can send the Base64 value to me so I will test it myself.
Hope you are doing well in these tough times. This is very detailed work, what you have done here.Thanks for making it available to us.
I wanted to know a bit more about what really is pdf. Suppose we are opening a pdf file in a text editor something similar. It provides the result as
%PDF-1.5

This is not the entire pdf file data. I would like to know
(1). what type is this data? ,and
(2). if we are having access to this data file, is it possible to recreate the original pdf?
(3). Also is the instance mentioned above (2) possible in javascript?
Thanks and Regards,
Rony Mathews
PS : The work you have been doing on this site seems really extensive. Kudos to you.
Siddhartha
i see the in top of "preview pdf" the origin file name , this can be resolved?
I used one of the base64 to decode it into a pdf, so I am able to download the created pdf but unfortunately its preview went missing on your web page. Why is so ? why I have to download the file and open in my local machine ?
1) The PDF file or Base64 string is corrupted.
2) Your browser cannot display PDF files embedded into webpages.
3) The PDF file is too big and your device is out of memory.
4) Your browser cannot handle Data URIs.
I saved the base64 file here: https://ghostbin.com/paste/VR6uD
Thanks in advance
preview pdf is showing blank when I am open in Iframe
The MIME of file was detected as “text/plain”, but the decoder displays it as “application/pdf”. To view it as is, use the Base64 to file converter.
any idea why this hapen?
Excellent job, I saved a lot of time to make some tests.
Many thanks!!
while problem
byte[] dataBuffer = Convert.FromBase64String(AEducationNew.FileBody);
using (FileStream fileStream = new FileStream(vDirectoryKB, FileMode.Create, FileAccess.Write))
{
if (dataBuffer.Length > 0)
{
fileStream.Write(dataBuffer, 0, dataBuffer.Length);
}
}
My server does not store any data submitted by users during decode/encode processes. All data is processed on the fly and everything is erased from RAM even before your browser displays the results.
ic possible combine two or more b64 strings?
and give me message "your browser cannot display the file as "application/pdf""
Regards,
B.
I can't download
I have the following header:
<document classCode="DOC" moodCode="EVN"><code code="2" codeSystem="2.16.840.1.113883.3.989.2.1.1.27" codeSystemVersion="2.0" displayName="literatureReference"/><text mediaType="application/pdf" compression="DF" representation="B64">Base64 to PDF/Base64 to file conversions failed. Could it be that compression="DF" is performing additional compression?
I will be happy to read every comment and, if necessary, I will do my best to respond as quickly as possible. Of course, spammers are welcome only as readers.
