Doc Guru is a professional PDF editor and reader that works on your phone. Open a file, read it, annotate it, and run PDF tools without creating an account and without uploading documents to a server.
Your PDFs stay on this device. Doc Guru does not use the internet permission, does not show ads, and does not send your files, passwords, annotations, or ratings to our servers.
READ PDFs
• Open PDFs from Files, email, or other apps
• Pinch to zoom and jump to a page
• Night reading mode
• Bookmarks for pages you want to return to
• Share or print a document
• Open password-protected PDFs with a password you already know
EDIT PDFs
• Pen, highlight, text, and eraser
• Undo while you work
• Save a new copy — Doc Guru does not overwrite your original file
PDF TOOLS
• Merge several PDFs into one
• Split a range or extract every page
• Compress a large file
• Create a PDF from photos
• Organize pages: reorder, rotate, or drop pages
• Export pages as PNG images
• Protect a copy with a password
• Unlock a copy you can already open with the known password
• Add a text watermark across every page
PRIVACY
There is no sign-in and no cloud account. Tools create a new file you choose. You can delete recents, bookmarks, ratings, and cache any time from Settings → Delete my data. That action does not delete the original PDFs in your storage — those files belong to you.
NOTES
• Unlock only works when you enter the correct password. Doc Guru does not bypass protection you do not own.
• Keep new passwords somewhere safe. The app cannot recover a forgotten password.
• Processing happens on the device, so very large files may take longer on some phones.
