Scriba: Read, Edit & Sign PDF

EDUSHARK

About this app

Scriba is a fast, private PDF reader, editor and signer that works entirely on your phone. It does not even request the internet permission, so your documents never leave your device. No account, no sign-up, no ads, no tracking.

PRIVATE BY DESIGN
- No internet permission: you can check this in the app's permission list.
- No account, no ads, no analytics, no data collected.
- Everything runs on your device, so it works offline.

FREE AND UNLIMITED
- Every feature is free: no subscription, no watermark, no page limits.
- Forms, signing, redaction, OCR, password protection and page organizing are all included.

FREE CERTIFICATE SIGNING
- Sign PDFs with a real digital certificate (PAdES), not just a picture of a signature. Any later change to the file is detectable by PDF readers.
- Import your .p12 / .pfx certificate, or create one on your phone.
- Add a reason and location to each signature.

READ FAST
- Smooth scrolling and zoom, even on long documents.
- Search every page and jump between matches.
- Select and copy text, then highlight or underline it.
- Contents, internal links, bookmarks, thumbnails and go to page.
- Normal, night and sepia reading modes.
- Opens password-protected PDFs.

MARK UP
- Highlight, underline, freehand ink, text, sticky notes, shapes and stamps.
- Choose colors, stroke width and opacity. Undo and redo.
- Saved as real PDF content, so pages stay sharp and text stays selectable.

FILL FORMS
- Detects real PDF form fields: text, checkboxes, radio buttons and dropdowns.
- Move from field to field, then keep the form fillable or flatten it.
- No form fields? Type values anywhere on the page.
- Save your details in fill profiles and fill matching fields in one tap.

SIGN AND EDIT
- Draw or import your signature, then place, resize and rotate it.
- Save signatures and reuse them.
- Fix a word or line of text by tapping it.

SCAN, OCR AND CONVERT
- Scan paper with your camera app: auto crop, perspective fix and filters.
- Recognize text (OCR) on scanned pages so you can search, select and copy.
- Turn photos into a PDF, or compress a PDF to share it more easily.

REDACT
- Black out words, phrases or areas. The content under each box is removed from the file, not just covered.

ORGANIZE AND PROTECT
- Merge, split, reorder, rotate, delete and extract pages.
- Add a password (AES-256), set print and copy permissions, or save an unlocked copy.

YOUR LIBRARY
- Opened and shared PDFs are kept in the app's library with thumbnails.
- Search, sort, rename, share, print or save to any folder.

GOOD TO KNOW
- Text editing covers the old text and writes the new text on top, so the original words remain in the file. Use Redact to remove content.
- OCR recognizes English text.
- New text uses your device's fonts, not the document's original font.
- Certificates you create on the phone are self-signed: readers show the signature as valid but the signer as not verified by an authority. Use a certificate from a certificate authority for a trusted identity.
- Editing a PDF that is already digitally signed invalidates its existing signatures (Scriba warns you first).
