Help center
Short, practical answers. Start with a tool category or jump to a common question.
Tool categories
Privacy
- Do my files leave my device? — No. There is no upload step and no document server. Files are read in-browser only — including the PDF editor at /edit.
- What data is stored locally? — Theme preference, optional activity history (tool name + time), and saved Pro presets live in this browser’s local storage. Pro billing stores a Stripe customer reference in a cookie so this device can check your subscription. None of this includes document contents.
- Can PDFIntro see my documents? — No. We have no technical ability to — the processing code runs in your tab, not on our infrastructure.
Using the tools
- How does the PDF editor work? — Open /edit, drop your PDF, add signatures, text fields, checkboxes, and images from the toolbar. Use Arrange to drag and resize fields, Fill to enter values, then Download PDF or Print → Save as PDF. Everything stays on your device.
- How do I reorder pages before merging? — In tools that support it, drag the file rows up and down. The order shown is the order used.
- Why is compress slower than merge? — Compress is a Pro tool that re-renders each page to an image at your chosen resolution, which is more work than copying page objects.
- Which browsers are supported? — Any modern Chromium, Firefox or Safari release. WebAssembly and the File API are required.
Account & billing
- Do I need to sign up? — No PDFIntro account. Free tools need no login. Pro checkout goes through Stripe — use the same email on a new device and request a restore link from Settings.
- Are paid plans live? — Yes. Pro is $6/mo via Stripe. Subscribe on Pricing, manage or cancel in Settings → Manage subscription, and restore on another browser with the email you used at checkout. Business is coming soon.
- What does Pro include? — Compress, flatten, remove metadata, password protect, unlock PDF, in-browser OCR, multi-step workflows, and saved tool presets. Organise, convert, edit tools and the /edit PDF editor stay free.
- How do I restore Pro on a new device? — Go to Settings or /billing/restore, enter the email from Stripe checkout, and click the magic link we send (valid for one hour). Your PDFs are never involved — only billing status is checked.
- Do you store my card details? — No. Stripe handles payment securely. PDFIntro only keeps enough billing state on this device to know whether your Pro subscription is active.
