About Pdfmark.
Pdfmark is a pay-per-use PDF tool operated by TerraSight Corporation. We build small, focused browser tools that cost a flat $2.99 per finished file instead of asking you for a monthly subscription.
Why this exists
Most PDF tools charge $10 to $20 a month for what most people need maybe once a quarter. If you sign a lease every couple of years, fill out a W-9 at a new client, or send a contract to a recruiter, a subscription is the wrong shape of pricing. Pdfmark exists for that occasional use. You open a tool, do the job, pay $2.99, and you're done.
What we deliberately don't do
- No accounts and no sign-up. There is no profile or password to remember.
- No subscriptions. The price is $2.99 per finished file, full stop.
- No advertising or behavioural tracking. We don't load third-party analytics or remarketing pixels.
- No data retention after sessions. Editor sessions delete after 24 hours; tracker share links after 7 days.
- No training of AI models on your files. The PDFs you upload are not used for anything other than the tool you opened.
How Pdfmark is built
Pdfmark runs on Next.js, with pdf-lib doing the final server-side render of every paid PDF and pdf.js handling the in-browser preview. Files live in Vercel Blob storage for the session lifetime described above. Payments are processed by Stripe; tracker emails are sent through Resend. We chose this stack to keep the surface area small and the trust boundary clear.
The architecture is described in plain English at /privacy and the machine-readable API contract is published at /openapi.yaml.
Who runs Pdfmark
Pdfmark is built and operated by TerraSight Corporation, an independent software company. The team behind it has shipped consumer and prosumer document tooling for years; we built Pdfmark because we wanted something we'd use ourselves.

Where Pdfmark is going
The two tools live today (an editor and a document tracker) cover the most common reasons people open a PDF. Over time we expect to add more single-purpose tools that fit the same flat $2.99 model: redaction with a verification certificate, a proper compressor, OCR for scanned documents, and form-specific workflows for the documents people fill out most often.
Every new tool will follow the same rules: no account, no subscription, one price per finished file.
