How to Transfer Your JPEGmini License to a New Computer

Quick Summary

Every JPEGmini license allows 3 simultaneous activations. If you've reached your limit and need to install on a new computer, you must first deactivate an old installation. This article shows you how.

Key Points:

• ✅ 3 computers maximum at once (Mac, Windows, or mix)

• ✅ Easy deactivation from within the app (takes 30 seconds)

• ✅ Old computer dead/sold? We can reset activations manually

• ✅ Transfer between Mac and Windows (v3/v4 only)

• ✅ Need more than 3? Consider Team License

Understanding the 3-Computer Limit

How Licensing Works

Each JPEGmini license (Pro or Suite) includes:

• ✅ 3 simultaneous activations

• ✅ Can be any mix of Mac and Windows (v3/v4 only)

• ✅ Can deactivate and move freely

• ✅ No time limit on transfers

Example valid setups:

• 3 Mac computers

• 3 Windows computers

• 2 Macs + 1 Windows

• 1 desktop + 1 laptop + 1 backup computer

What Happens at the Limit

Scenario: You've already activated on 3 computers and try to activate on a 4th:

❌ Error message: "This activation code has already been used to activate JPEGmini on another computer."

Solution: Deactivate on one of your existing computers first.

Why the 3-Computer Limit?

This is a generous policy:

• Prevents license sharing/piracy

• Covers typical usage (desktop + laptop + backup)

• Allows flexibility (home, work, travel)

• No restrictions on how often you transfer

Compare to competitors:

• Some allow only 1-2 computers

• Some charge per computer

• JPEGmini: 3 included, unlimited transfers

Common Use Cases

Work + Home Setup

• Computer 1: Work desktop (Mac)

• Computer 2: Home desktop (Windows)

• Computer 3: Laptop (for travel)

Multi-User Setup (Same License)

• Computer 1: Photographer's desktop

• Computer 2: Assistant's computer

• Computer 3: Backup machine

Upgrade/Replacement Cycle

• Keep 2 slots active

• 1 slot free for testing new computers

• Deactivate old when you upgrade

Old Computer Is Inaccessible (Manual Reset)

Common Scenarios

When you can't deactivate normally:

• 🔴 Computer is broken/dead

• 🔴 Computer was sold

• 🔴 Computer was stolen

• 🔴 Computer was wiped/formatted

• 🔴 Operating system crashed

• 🔴 Lost access to work computer (left job)

Don't panic! We can manually reset your activations.

• Your activation code

• Email used for purchase

• Reason for reset request

Optional but helpful:

• Order number

• Number of computers affected (1, 2, or all 3)

We will:

1. ✅ Verify your ownership (matches purchase records)

2. ✅ Reset your activations (all 3 slots freed)

3. ✅ Send confirmation email

4. ✅ You can immediately activate on new computer

Important: We can only reset activations, not recover lost activation codes. If you lost your code, see: "How Do I Retrieve My Activation Code?"

After Reset

What happens to old computers:

• If old computer is recovered later, it won't be activated

• You can reactivate up to 3 computers again

Best practice:

• Keep track of your activations

• Deactivate before selling/wiping when possible

<a name="cross-platform"></a>

Cross-Platform Transfers (Mac ↔ Windows)

v3/v4: Full Cross-Platform Support

Good news: v3/v4 licenses work on both Mac and Windows!

✅ You can:

• Activate same code on Mac

• Activate same code on Windows

• Mix platforms across 3 computers

• Transfer from Mac to Windows (or vice versa)

Example setups:

• 2 Macs + 1 Windows = ✅ Valid

• 1 Mac + 2 Windows = ✅ Valid

• 3 Macs or 3 Windows = ✅ Valid

v2: Platform-Specific Licenses

Important: v2 licenses are platform-locked:

❌ v2 Mac license: Mac only
❌ v2 Windows license: Windows only

If you have v2 and want to switch platforms:

• Option 1: Buy v2 license for other platform (full price)

• Option 2: Upgrade to v3/v4 (cross-platform + new features)

Recommended: Upgrade to v3/v4 for flexibility!

👉 [See: Upgrading from JPEGmini v2 to v3/v4]

How to Transfer Cross-Platform (v3/v4)

Scenario: Moving from Mac to Windows (or vice versa)

Process is identical:

1. Deactivate on Mac (if accessible)

2. Download Windows installer

3. Install on Windows computer

4. Activate with SAME code (the one from Mac)

5. ✅ Done!

Your code works on either platform - no special "Mac" or "Windows" code needed.

Checking How Many Activations Are Used

Can I See My Activation Count?

Unfortunately, no. JPEGmini doesn't have a user dashboard showing:

• How many activations are currently used

• Which computers are activated

• When each was activated

This is a known limitation we're working to improve.

How to Track Manually

Keep a list:

Update when you:

• Activate on new computer

• Deactivate from old computer

• Sell/replace a computer

What If You're Not Sure?

Try activating:

1. Install JPEGmini on new computer

2. Try to activate with your code

Result A: ✅ Activation succeeds

• You had slots available

• New computer is now active

Result B: ❌ "Already activated" error

• All 3 slots are used

• Need to deactivate one first

If you can't remember which computers are activated:

• Contact support: support@jpegmini.com

• We can reset all 3 slots for you

• Then activate only the computers you're currently using

Frequently Asked Questions

What happens if I forget to deactivate before selling my computer?

Don't worry! This happens often. Here's what to do:

Step 1: Try to deactivate remotely

• If you can still access the computer remotely

• Or if buyer hasn't wiped it yet

Step 2: If that's not possible

• Contact support: support@jpegmini.com

• Request manual activation reset

• We'll free up your slots

Step 3: Activate on new computer

• After reset, you can immediately activate on new devices

Important: We can't "force deactivate" a specific computer remotely. We reset ALL activations, so you'll need to reactivate any computers you're still using.

Can I temporarily deactivate during computer repairs?

Yes! Great idea to protect your activation:

Before repair:

1. Deactivate JPEGmini (Help → Deactivate)

2. Send computer for repair

3. Your activation slot is freed

After repair:

1. Get computer back

2. Reactivate with same code

3. ✅ Back to work!

Why this helps:

• If repair shop wipes/reformats, your activation isn't stuck

• If computer can't be repaired, you don't lose an activation slot

• Peace of mind during repairs

Does deactivating delete my optimized photos?

No! Deactivation only affects the license:

✅ What stays:

• All your optimized photos

• Original files

• JPEGmini settings/preferences

• Application files

❌ What changes:

• JPEGmini requires reactivation to run

• Activation slot is freed for another computer

Think of it like: Logging out of an app, not deleting the app.

Can I activate on a virtual machine (VM)?

Technical answer: Yes, but with limitations.

Each VM counts as a separate computer:

• VM 1 = 1 activation

• VM 2 = 1 activation

• Physical computer = 1 activation

• Total: 3 activations (your limit)

Common scenario:

• Mac physical: 1 activation

• Parallels Windows VM: 1 activation

• Remote desktop: 1 activation

• = All 3 slots used

Best practice:

• Use JPEGmini on host computer, not VMs

• Or consider Team License for multiple VMs

What if I upgrade my computer (new hard drive, etc.)?

It depends on what you upgrade:

Scenario A: Same computer, new hard drive/OS

• Deactivate before wiping/upgrading (if possible)

• After upgrade, reinstall JPEGmini

• Reactivate with same code

• ✅ Uses same activation slot

Scenario B: Completely new computer

• Deactivate on old computer

• Install on new computer

• Activate on new computer

• ✅ Transfers activation slot

Scenario C: Forgot to deactivate before upgrade

• JPEGmini may see it as "new" computer

• If you hit activation limit, contact support

• We'll reset activations

Tip: When in doubt, deactivate first!

Can I share my license with a friend/colleague?

Not recommended. Here's why:

Licensing terms:

• 3 activations for your personal/business use

• Not for sharing between unrelated users

• Violates license agreement

Practical issues:

• If friend hits activation limit, affects your use

• Can't control when friend deactivates

• License tied to your purchase/email

Better options:

• Each person buys their own license

• Business: Purchase Team License

• Temporary need: Consider trial/Free version

Educational/non-profit: Contact us for special pricing!

Does transferring licenses affect my license expiration date?

No! Transfer doesn't change expiration:

✅ Stays the same:

• Expiration date unchanged

• Remaining update period unchanged

• License terms unchanged

Example:

• License expires: June 1, 2026

• Transfer today: Still expires June 1, 2026

• Doesn't restart or extend

To extend: See "How to Extend Your v3 License" article.

Can I transfer just 1 activation, keep 2 active?

Yes! You have full control:

Example:

• Computer A: Active (keep)

• Computer B: Active (keep)

• Computer C: Active (want to replace)

Process:

1. Deactivate only Computer C

2. Computers A & B stay active

3. Activate on Computer D (new)

Result:

• Computer A: ✅ Active

• Computer B: ✅ Active

• Computer C: ❌ Deactivated

• Computer D: ✅ Active

You're only moving 1 activation, not all 3!
