Yes, completely. Alteri processes your PDFs entirely in your browser — your files are never uploaded to our servers. We literally can’t see your documents. Once you close the tab, they’re gone.
The plans scale up in both duration and features. The 1 Week plan covers the essentials — text editing, annotations, and basic signatures — ideal for a one-off task. The 1 Month plan unlocks freehand drawing, upload signatures, split & merge, and form filling with up to 20 documents. Lifetime gives you everything, unlimited documents, 100 MB files, priority processing, future features, and priority support — for a single one-time payment.
Most PDFs, yes. Alteri detects existing fonts and lets you edit text in-place while preserving the original style. If a font isn’t available, we match it with the closest alternative. Heavily secured or encrypted PDFs may have restrictions set by their creator.
It means you pay once and have access forever — no renewals, no subscriptions, no surprise charges. It also includes all future features we ship. We’d never gate new tools behind a new purchase for lifetime customers.
We accept all major credit and debit cards (Visa, Mastercard, Amex) as well as PayPal and Apple Pay. All payments are processed securely via Stripe.
Yes. If you’re not satisfied, contact us within 7 days of purchase at hello@alteri.com and we’ll process a full refund — no questions asked.
