Who it's for

Is it right for you?

A good fit if

You handle forms, scans, contracts or school and work paperwork on an Android phone
You'd rather not upload private documents to converter websites
You're tired of watermarks, daily limits and monthly PDF plans
You want one guided app instead of five tabs
You also use a Windows 10/11 PC

Not a fit if

You only have an iPhone, iPad or Mac
You need certificate-based digital signatures
You only merge one PDF a year (a free site may be enough)
You want an app from Google Play: this installs from the downloaded APK

Look inside

Real pages and screens

Happy cartoon kangaroo next to the real Concierge screen What would you like to do? — **Document Concierge** Not sure which tool to use? Pick a goal: scan and send, sign and return, make a file easier to send, copy text, combine PDFs, prepare for private sharing.

Proud cartoon kangaroo next to two real Images to PDF screens — **Photos to one PDF** Add photos or take new ones with the camera, put the pages in order, choose page size, then create and save the PDF.

Happy cartoon kangaroo next to the real Image to Text screen — **Copy text from scans** Image to text, scan to text, PDF to text and searchable PDFs. English text recognition is built in and works offline; other languages download their data once. On Windows, OCR works when you open the app with the included launcher. Always proofread names and numbers.

Proud cartoon kangaroo next to two real signature screens: drawing a signature and the signed page saved — **Signatures, honestly** Draw your signature, save it on your phone and place it on any page. It's a drawn electronic signature, not a certificate-based digital signature, so check what your document requires.

Three real screenshots: drawing a signature, the Read, edit and organize PDFs tool list, and the Images to PDF page list — **Create, edit and sign** Photos and camera scans to one PDF. Word, Excel and PowerPoint text, TXT, Markdown, HTML, CSV, JSON, XML and copied web or email content to PDF (complex layouts are simplified). Reader with search, merge, split and extract, rotate, reorder, add text, whiteout, watermark, page numbers, headers and footers, Bates numbering, crop and resize. Draw a signature, save it and place it.

Three real screenshots: the redaction tool, the Precision and privacy tool list, and the PDF Health Check — **Privacy tools** Secure redaction (the page is flattened, so the text under the box is removed), Privacy Clean for common metadata and form data, and a PDF Health Check: is it searchable, are the pages the same size, are there open form fields, is it heavy for a phone?

Cartoon kangaroo next to a laptop showing the real computer edition home screen, with badges Android 10+, Windows 10/11, Not iPhone/iPad, No Mac — **Android app + Windows edition** An Android app (APK) for Android 10 or newer, plus a computer edition for Windows 10/11 that opens in Chrome or Edge (a local browser app, not an installer). Not for iPhone or iPad, and no Mac edition.

Three real screenshots: Compress PDF options, the Lossless mode and Honest quality protection note, and the Concierge's Make a PDF easier to send steps — **Detail** Compression that tells the truth. Lossless keeps text, forms and image quality unchanged. Target sizes (under 10, 5, 4, 2 or 1 MB) are a goal, not a guarantee: target modes turn pages into images, so detail can drop and text is no longer selectable (form fields and links are removed). You see the before and after size.

Check before you buy

Will it work on your device?

Please check this first. There's no iPhone version.

What will you use it on?

Tap your device above.

✅ Yes

Install the APK from your download (not from Google Play). Android may ask you to allow installs from that source and may show an "unfamiliar developer" message; the START-HERE guide walks you through it.

❌ Not supported

Pocket PDF Studio is supported on Android 10 or newer. Please don't buy it for an older phone.

✅ Yes, with Chrome or Edge

Extract the zip, open the folder and double-click the launcher; the app opens in your browser. It's a local browser app, not an installer. Core tools and English OCR work when you start it with the launcher (opening index.html directly works for basic tools, but OCR needs the launcher).

❌ No

Not for iPhone or iPad. iOS can't install Android apps.

❌ No Mac edition

There's no Mac edition, so please don't buy it for a Mac.

If your device got a green light, you're good to go.

FAQ

Questions about Pocket PDF Studio

$38 for a PDF app?

It's one price for 41 tools on your Android phone and Windows PC, with no subscription, no watermark and no account. If you only need one PDF job a year, a free site may be enough.

I'm not techy. Can I use it?

Yes. The Document Concierge asks what you want to do and opens the right tool with simple steps, and there's a search box for every tool. The START-HERE guide covers the install and your first five minutes.

Can't I do this free?

Free websites can merge or compress, but many upload your file, add watermarks or limit you each day. This keeps the core tools on your device in one place. If you only need one merge a year, a free site may be enough.

I have an older version. Can I update?

Yes, on Android 10 or newer: keep v38, v39 or v40 installed, install the v41 APK and choose Update. v41 no longer supports Android 8 or 9.

Does it work on iPhone, iPad or Mac?

No. Not for iPhone or iPad (iOS can't install Android apps), and there's no Mac edition. It's for Android 10+ and Windows 10/11.

Does it work on Windows?

Yes. The Windows 10/11 edition opens in Chrome or Edge: extract the zip and double-click the included launcher (a local browser app, not an installer). Core tools and English OCR work when you start it with the launcher.

Does it need internet?

The core tools (create, edit, merge, sign, compress, redact) run on your device. English text recognition is built in and works offline. Non-English OCR languages, opening websites, updates and some share destinations need internet. Try a simple task in airplane mode to check on your device.

Is a signature from the app legally valid?

It's a drawn electronic signature, not a certificate-based digital signature. Check what your document requires.

Why isn't it on Google Play?

It installs from the APK file you download. Android may show an "unfamiliar developer" message; the guide explains what to check. Keep Play Protect on.

Can I get a refund?

7-day refund if the file is unused, corrupt, or materially misrepresented. Contact paidigitalstore@gmail.com. This doesn't limit your rights under applicable consumer law.
