About FlareStore Web Signer

FlareStore Web Signer is a browser-based IPA signing tool that lets you sign iOS apps without needing a Mac, Xcode, or any desktop software. Upload your IPA file along with a P12 signing certificate and mobileprovision profile, and the signer handles the full code signing process on our servers — returning a ready-to-install signed app in seconds.

The Web Signer supports single and batch signing, custom bundle ID modification, app icon replacement, file sharing injection, and URL scheme configuration. Whether you're signing a single app for personal use or batch-processing multiple IPAs for testing, FlareStore handles it all from any device with a web browser — including directly from your iPhone or iPad.

What You Need to Sign an App

To sign an IPA file, you need three things: the IPA file (the iOS app package you want to install), a P12 certificate (your signing identity that tells iOS the app comes from a trusted source), and a mobileprovision profile (which specifies which devices are allowed to run the app and what capabilities it can use).

You can obtain signing certificates from the FlareStore Store with various plan tiers, or try our free community certificates for testing. If you're not sure about the status of your certificate, use the Certificate Checker to verify its validity before signing. Need your device UDID first? Use our UDID Grabber.

Advanced Signing Options

The Web Signer includes several advanced options for power users. Custom Bundle ID lets you change the app's identifier, which is useful for installing multiple versions of the same app side by side. Custom Icon replaces the app's icon with an image of your choice. File Sharing enables the app to exchange files through iTunes/Finder.

For batch operations, you can upload multiple IPA files at once and sign them all with the same certificate in a single pass. This is particularly useful for developers or users who manage several sideloaded apps and need to re-sign them after a certificate renewal. For programmatic access to our signing infrastructure, check out the FlareStore API documentation.
