Frequently asked questions

Common questions about tools, credits, and billing.

Are the tools really free?: The DPI checker and converter, pixels-to-inches, and the pattern checker are free and unlimited, with no sign-up and no watermark. Print Resize and the Pattern Generator use credits.
What are credits for?: Credits pay for Print Resize, the Pattern Generator and AI Upscale. Print Resize costs 1 credit when only pixels are added, typically 9 credits for a full rebuild, and more for extra-large prints. AI Upscale is 1 credit at 2K, 2 at 4K, and 3 at 8K. The Pattern Generator shows its cost before the run. Failed runs are refunded, and credits never expire.
Is there a subscription?: No. PrintResize uses one-time credit packs only — Starter ($9.90/60), Standard ($19.90/150), and Max ($39.90/350). Buy once, use them whenever.
Do credits expire?: Never. One-time purchase, permanent balance. No monthly refresh, no expiry emails.
What do I get for registering?: An account gives you 3 free credits to try the AI actions, plus your credit balance and history. The free tools need no account at all.
Can I use the results commercially?: Yes. Output from both free tools and AI actions is yours to use, including commercial print-on-demand and fabric production.
Which payment methods do you accept?: Card payments via Stripe. Checkout is one-time — no stored payment method, no recurring billing.
What if an AI action fails?: Failed actions are refunded automatically — the reserved credit returns to your balance within a minute.
