How can we help?
Answers to the most common questions about MRS: PDF Editor App.
How do I scan a document?
Open the app and tap the camera button. Hold your iPhone over the page — the app detects the edges automatically and captures the shot. You can then crop, straighten and enhance before saving as a PDF. For multi-page scans, keep capturing and the pages are added to the same document.
Can I edit existing PDFs?
Yes. Import any PDF from your Photos library or the Files app, then open it in the editor. You can add text, draw highlights, insert images and drop in your signature — all without converting the file to another format.
How do I add a signature?
Open any PDF, tap the signature tool and draw your signature with your finger. The app saves it so you can reuse the same signature on future documents. Once placed, you can move, resize or rotate it to fit the signature line.
How do I cancel my subscription?
Subscriptions are managed through your Apple ID. On your iPhone, go to Settings → [your name] → Subscriptions, select MRS: PDF Editor App and tap Cancel Subscription. You'll keep Pro access until the end of the current billing period, and there will be no further charges.
What file formats are supported?
The app imports PDF, JPG, PNG and HEIC files. All scans and edited documents are saved as standard PDFs, so they open in any PDF viewer across iOS, macOS, Windows and Android.
How do I share or export documents?
Tap the share icon on any document to open the standard iOS share sheet. From there you can send the PDF via Mail, Messages, AirDrop, iCloud Drive, or to any other app that accepts files.
Is my document data stored on your servers?
No. Your scans and PDFs stay on your device. We do not upload or permanently store the content of your documents on our servers. Only minimal, anonymous usage analytics and your subscription status are processed — see the Privacy Policy for details.
What iOS version is required?
The app runs on recent versions of iOS on iPhone. For the exact minimum iOS version and compatible devices, check the App Store listing.
