Pricing FAQ
How does the free trial work?
Every visitor gets one free document per tool — no card needed. Signed-in accounts also get one free document, then each use costs credits.
Do credits expire?
No. Buy any amount, use them whenever. Credits stay on your account forever.
Is a subscription required?
No. PDF Ninja Tools is pay-as-you-go — you only spend credits when you process a file.
Do I need an account?
Only after your first free use of a tool. Sign-up takes seconds and you keep your remaining free document plus any credits you buy.
How are payments handled?
Securely via our payment processor. We accept Visa and Mastercard. You'll see a receipt for every top-up in your account history.
Can I get a refund?
Credits are non-refundable once used. If you bought credits and never used them, email info@pdfninjatools.com and we'll sort it out.
