To jailbreak iOS 12.5.7 (common for iPhone 5S, 6, 6 Plus, iPad Air, iPad Mini 2, and Mini 3), you have three main reliable options depending on whether you have a computer. Option 1: Chimera (No Computer Method)
This is a semi-untethered jailbreak, meaning you must re-run the app if your device reboots.
Download: Open Safari and visit a reputable third-party app site like ipa-apps.me.
Install: Search for Chimera (or Freya) and tap Get > Install.
Trust Profile: Go to Settings > General > Profiles & Device Management. Tap the developer name and select Trust.
Jailbreak: Open the Chimera app and tap the Jailbreak button. Your device will reboot.
Finalize: After rebooting, open Chimera again and tap Jailbreak once more to finish installing Sileo. Option 2: 3uTools (Windows PC Method)
This method is often more stable than the "No Computer" method as it isn't subject to common app certificate revokes.
Preparation: Install the latest version of iTunes and 3uTools on your Windows PC.
Connect: Plug your device into the PC via USB and unlock it.
Run Tool: In 3uTools, go to the Toolbox tab and click Jailbreak.
Select Chimera: Select the Chimera tool from the list and follow the on-screen prompts to sign it with your Apple ID.
Trust & Run: Once the app appears on your phone, trust the profile in Settings (as shown in Option 1) and run the jailbreak inside the app. Option 3: Checkra1n (Advanced / Mac & Linux)
This is a "hardware-level" jailbreak. It is extremely stable but requires a computer every time you reboot.
Download: Get the Checkra1n tool for Mac or use a bootable USB for Windows (using a tool like Rufus with a Checkra1n ISO).
DFU Mode: Follow the on-screen instructions to put your device into DFU Mode (usually involves holding Power and Home buttons).
Exploit: The tool will run the exploit and reboot your device with the Checkra1n loader app installed.
Install Cydia: Open the Checkra1n loader on your device and tap Install Cydia. Important Notes
Backup First: Always back up your data to iCloud or iTunes before attempting any jailbreak.
Semi-Untethered: If your battery dies or you restart, you must re-open the jailbreak app (Chimera) and tap "Enable Jailbreak" to get your tweaks back.
Legality: Jailbreaking is generally legal for the purpose of software interoperability, but it voids your Apple warranty.

If you search for a jailbreak tool for iOS 12.5.7 today, you will encounter a fragmented landscape. Unlike the golden age of jailbreaking, where tools like RedSn0w or Pangu were household names, the current scene is largely dormant for legacy devices.
The primary hurdle is technical. iOS 12.5.7 patched several critical kernel vulnerabilities. While the checkm8 hardware exploit—a permanent bootrom vulnerability—works on devices like the iPhone 5s, 6, and 6 Plus, utilizing it is not as simple as downloading an app.
Currently, the most viable path involves tools like Palera1n or older iterations of Checkra1n. However, these require a macOS or Linux computer and often involve a "tethered" or "semi-tethered" process. This means the device needs to be connected to a computer every time it reboots. For the average user looking for a quick "one-click" download, this barrier to entry is often insurmountable.
