Local-first document tools: scan, OCR, convert between images and PDF, and turn Office files into real text PDFs. Your documents never leave your device.
Why DocUtils
• Everything runs on your device. Documents, photos and recognised text are never uploaded.
• No account, no sign-in, and the main features work offline.
• Ads appear only when you tap "Watch video for one export" — no app-open, interstitial or banner ads.
Features
Camera scan
• Shoot with the camera, or import several photos from your gallery at once.
• Automatic page-edge detection; perspective correction straightens skewed photos.
• Filters: Original, Auto-enhance, Grayscale, Black-and-white. Auto-enhance first estimates and flattens uneven page lighting (shadows, half-dark pages) so the whole page has consistent contrast.
Images to PDF
• Combine photos into one PDF with vertical, horizontal or grid stitching.
• Page size (A4 / Letter and more), orientation, and text or image watermarks (centred, tiled, corners).
PDF to images
• Export each page, merge everything into one long image (set the width; memory stays low on long documents), or combine selected pages.
• PNG / JPEG, DPI, and page ranges such as 1-5 or 7-.
Scan to editable document
• On-device OCR (Google ML Kit): Latin, Chinese, Japanese, Korean, Devanagari.
• Export editable Word (.docx), Excel (.xlsx with kept rows, columns and merged cells) or PDF.
Office to PDF with real text
• Convert Word (.docx), Excel (.xlsx) and PowerPoint (.pptx) with a built-in on-device layout engine.
• The result is a true text PDF — selectable and searchable, not page images — keeping tables, merged cells, sections, headers/footers, footnotes and bookmarks.
• Text or image watermarks.
Made for
• Turning contracts, receipts and book pages into a tidy PDF.
• Converting scans into editable Word or Excel.
• Sending Office files in a fixed layout.
• Turning PDFs into long images for chat and social apps.
Free and paid
• Files up to 3 pages can be saved and shared for free, without limit.
• Above 3 pages: one free export per month. After that, subscribe to the yearly plan or watch a rewarded video for one more export.
• Limits are counted in pages (a merged long image counts as its pages), not files.
Language
• Chinese and English UI, following your device language, with a manual override.
Save and share
• Save anywhere through the system file dialog (easy to find in your file manager), or share straight to other apps. Exporting several images only asks for a folder once.
Privacy
• Documents, photos and recognised text never leave your device; the app uploads nothing.
• Only when you actively use the rewarded video or the subscription does the app talk to Google (ad and billing data is handled by Google under its privacy policy); those requests carry no document content.
• No account, and the app itself does no user tracking or profiling.
Known limitations
• Legacy .doc / .xls / .ppt, RTF and ODF are not supported; you'll be asked to re-save them in the new format.
• Office to PDF uses an independent on-device engine; very complex layouts may differ slightly from desktop software.
