Adobe also offers online merge, split, conversion and compression tools with free usage limits. Its published FAQ says most tools allow one transaction without signing in; signed-in free users can try premium tools once per rolling 30 days. These online services upload files to Adobe’s servers. The table above compares desktop tools.
alphaPDF is built for local PDF work in desktop Chrome. Acrobat offers broader desktop and mobile support, existing-text editing, certificate signing and managed e-signature workflows. alphaPDF’s visual signatures are not certificate signatures or a managed signing service.
For alphaPDF’s advanced tools, Pro is US$59 once, including applicable transaction tax, while alphaPDF remains supported. Adobe also sells Acrobat Pro 2024 with a three-year, non-recurring desktop licence.
Private by design
PDF contents, annotations, OCR and exports are processed locally in Chrome. alphaPDF servers handle only checkout, licence activation, recovery and limited installation management.
If you explicitly import a PDF from a website, Chrome may use your existing site cookies locally to retrieve it. The PDF is not sent to Maskia.

Good to know
No. Document contents and transformations stay in Chrome. Network access is used for the specific website PDF you ask Chrome to retrieve, checkout, licence activation and recovery.
No. Pro is a one-time purchase with no recurring charge. It covers the Pro tools listed when you buy it while alphaPDF remains supported.
Checkout is provided through Stripe Managed Payments. Link acts as merchant of record and handles payment, applicable transaction taxes and transaction support in the jurisdictions it covers. Your final total is shown before purchase.
You can activate up to three installations you control. The recovery flow lets you deactivate an old installation when moving to another computer.
The initial Pro purchase has a voluntary 30-day money-back guarantee, in addition to any stronger rights required by law.
No. alphaPDF is a practical local-first toolkit. It does not claim Adobe-compatible certificate signing, managed e-signatures or in-place editing of arbitrary source text.
The first release is built for current desktop Google Chrome versions that support Manifest V3 and the Side Panel API.
