Frequently Asked Questions
Got questions? We've got answers
Is ResizeWizard really free?
Yes! The free version includes all core features including quick presets, custom sizes (up to 5), live overlay, and theme support. The Pro version unlocks unlimited saved sizes and additional features.
Does it work on all websites?
ResizeWizard works on any regular website (http:// and https://). The overlay feature cannot be used on browser internal pages (chrome://) for security reasons.
Will my saved sizes sync across devices?
Yes! With Pro, enable the sync option in settings to keep your saved sizes and preferences synchronized across all devices where you're signed into Chrome.
How do I activate my Pro license?
After purchasing, you'll receive a license key via email. Open ResizeWizard settings (gear icon), enter your license key, and click Activate. Your Pro features will be unlocked instantly.
How many devices can I use my Pro license on?
Three at a time. Reinstalling no longer strands a slot — the daily license check recovers it. To free a slot immediately, click Deactivate in ResizeWizard settings before you uninstall. If a machine is gone for good, the Customer Portal releases its slot; sign in with the email you paid with (password or an emailed link) or with Google.
Is there a free trial?
Yes — Pro starts with a free 30-day trial. You won't be charged until the trial ends, and you can cancel anytime before then at no cost.
What if I change my mind?
Cancel any time during the 30-day free trial and you are never charged — the trial is how you try Pro, so there is nothing to refund. After the trial, a subscription runs to the end of the period you have paid for and then stops.
Does it collect any data?
No. ResizeWizard does not collect, store, or transmit any personal data. All your settings and saved sizes are stored locally in your browser or synced via your Chrome account if you enable sync.
