Features

Everything you do with PDFs.
Nothing you don’t want.

Redact

Redact for real. Then prove it.

Black boxes in most apps just cover the text, which is still in the file. PDF Edit Studio rebuilds every marked page, so the content is actually gone. Then it checks the result: page text, raw file bytes, OCR of the black areas, metadata and old revisions.

  • Find and mark emails, phone numbers, UK NI numbers, IBANs and card numbers in one click
  • Search-and-redact across the whole document, with regex if you need it
  • Export a verification report for your records
Redaction verified sheet listing seven passed checks
Ask & summarise

Ask your PDF anything.

Get a summary with key points and action items, or ask a question in plain English. Every answer cites the page it came from. Click the page number to jump straight to the passage. It all runs on your device with Apple Intelligence.

  • TL;DR, bullet or detailed summaries, exportable as Markdown
  • Answers with sources, so you can check them
  • Works offline, with no account

OCR

Scans become searchable text.

Turn scanned letters, invoices and handouts into PDFs you can search, copy from and redact. Apple Vision recognises the text page by page, so you can see it working, and your scan stays untouched.

Translate

Translate any PDF, side by side.

Read the original and the translation next to each other, then export the translation as a PDF, Markdown or plain text. It uses Apple Translation, so once a language is downloaded it works offline.

Add Signature sheet with a drawn signature

Sign in seconds

Draw, type or import your signature, place it, and flatten it on export.

Page grid with pages being reordered

Merge, split & reorder

Drag pages into order, combine files and split by page ranges like “1-3, 5, 7-9”.

Compress sheet with Light, Balanced and Strong presets

Compress for email

Light, Balanced and Strong presets show the size before you save. Your original is never overwritten.

Privacy

Private by design.
It runs on your device.

Document content never goes to Hokfam or anyone else. There’s nothing to sign up for and nothing to opt out of.

On-device by default

AI, OCR, redaction and translation all run locally, and they keep working offline.

No account, no tracking

No sign-up, no analytics, no third-party SDKs. We collect no data.

Verifiable redaction

Every redacted file is checked automatically, and you get a report you can keep as evidence.

Your choice for long files

On macOS 27 you can turn on Apple Private Cloud Compute for very long documents. It’s off by default.

FAQ

Questions, answered.

Is the redaction really permanent?

Yes. Marked pages are rebuilt from scratch, so the text and images under the black boxes are removed from the file, not just hidden. Pages without marks keep their original text. Each export is then checked automatically: page text, raw file bytes, OCR of the black areas, metadata, annotations and earlier revisions. You can save the report.

Are my documents uploaded anywhere?

No. AI, OCR, redaction and translation run on your device. The app has no account and no analytics. The only optional exception is Apple Private Cloud Compute for very long documents on macOS 27. It’s off unless you turn it on, and Apple states that this data isn’t stored or accessible to Apple.

Which devices support the AI features?

AI summaries and Ask this PDF need macOS 26 or iOS/iPadOS 26 on a device that supports Apple Intelligence, with Apple Intelligence turned on. Translation needs macOS 15 or iOS/iPadOS 18. On other devices the app shows key sentences from the document instead (no AI). Everything else, including redaction, OCR, signing, compression and organising, works on every supported Mac, iPhone and iPad.

Is the signature a legal digital signature?

It’s a simple electronic signature: your drawn, typed or imported signature placed on the page. It isn’t a certificate-based digital signature (PAdES). For many everyday agreements a simple electronic signature is enough, but check what your document needs.

What do I get for the price?

Everything, on Mac, iPhone and iPad. It’s a one-time purchase with every feature included, no subscriptions, no in-app purchases, no usage limits and no watermarks.

Can AI summaries be wrong?

Yes, summaries can contain errors. That’s why every point and answer links to the page it came from, so you can check the source in one click.

How do I get help?

Email pdfESupport@hokfam.com or see the Support page.

Can I use it on my other devices?

Yes. One purchase works on Mac, iPhone and iPad. Download it from the App Store on each device with the same Apple Account.
