Why does Cloudinary reject the file format of some files I'm uploading?

Many Cloudinary features are focused on image, video, and audio files but in general, it's possible to upload, manage, and deliver any file type.

However, there are some files which cannot be used with Cloudinary. This is to protect our service and users from formats which  may be potentially harmful files, executable files, or formats that may be used to distribute malware.

The following file extensions are rejected by default: 

action, apk, app, bat, bin, cmd, com, command, cpl, csh, exe, gadget, inf1, ins, inx, ipa, isu, job, jse, ksh, lnk, msc, msi, msp, mst, osx, out, paf, pif, prg, ps1, reg, rgs, run, sct, shb, shs, u3p, vb, vbe, vbs, vbscript, workflow, ws, wsf

Exceptions

If you have a paid Cloudinary account and you need to host some files of the types listed above, pleas e open a support request with us with more information about your requirements and the files. It may be possible for us to allow delivery of formats that are usually blocked for you either in general, or specifically when using your own hostname for asset delivery.
