IPA signer for iPhone
Sign IPA files on iPhone with a ready Apple certificate
CertDrop gives you the certificate and mobileprovision profile needed by IPA signing apps like ESign and Feather. No Mac setup, no Xcode, no confusing developer portal steps.
What an IPA signer needs
An IPA signer app cannot sign apps by itself. It needs a valid Apple signing certificate, a provisioning profile, and your iPhone UDID. CertDrop prepares those files so you can import them into ESign, Feather, or another compatible IPA signing app.
- Apple developer certificate for IPA signing
- Mobileprovision profile matched to your UDID
- Works with common iPhone signing apps
- Support if install or verification fails
Free IPA signers vs certificate signing
Many free IPA signer tools still require a certificate. Without one, apps may fail with verification, integrity, or provisioning errors. A paid certificate gives the signer app the files it needs to create an installable signed IPA.
How it works
- Get your iPhone UDID.
- Order your CertDrop certificate.
- Receive your certificate and mobileprovision files.
- Import them into ESign, Feather, or your IPA signer app.
- Sign and install your IPA file.

FAQ
Can I sign IPA files without a computer?
Yes, if you use an iPhone signing app and have the correct certificate and provisioning profile.
Is this a free IPA signer?
No. CertDrop provides the signing certificate and profile. You use those files with your preferred IPA signer app.
Why do signed IPA files fail to install?
Common reasons include a missing UDID, wrong provisioning profile, revoked certificate, expired certificate, or an IPA that is not compatible with your iOS version.
Trust, safety, and acceptable use
CertDrop is for apps you own, develop, test, or have permission to install. Do not use certificate files for piracy, malware, fraud, phishing, spyware, or bypassing rights you do not have.
Signing helps iOS verify an app package for installation. It does not make every IPA safe, legal, compatible, or functional.
