PDF guides
Practical notes for private PDF work.
These guides explain the document problems vinniDocu is built around: scanned PDFs, browser OCR, office file conversion, image-based PDFs, password protection and text export. They are written for people who want useful PDF workflows without sending private files to a remote converter.
How browser-based PDF tools protect your documents
Learn what local processing means, when a file stays on your device, and what to check before using any PDF tool.
OCRHow to OCR a scanned PDF privately
Understand when OCR is needed, how to prepare scans, and how to review extracted text before using it.
To PDFConvert Word, Excel, CSV and text files to PDF
Choose the right conversion path for office files, spreadsheet exports, tabular data and plain text notes.
ExportExport PDF text to Word, Excel, CSV or TXT
Know the difference between selectable PDFs and scanned PDFs before exporting text into editable formats.
ScansCreate a clean PDF from images and phone scans
Prepare receipts, forms, notes and photos so the final PDF is readable, ordered and easy to share.
SecurityPassword protect a PDF before sharing it
Use PDF passwords responsibly, understand the limits, and avoid common mistakes when sharing sensitive files.
File sizeHow to reduce PDF file size before sharing
Understand why PDFs become large and reduce size through page extraction, image choices and cleaner scans.
SignaturesHow to sign a PDF without printing it
Add visible signatures carefully, review the exported file and know when certified signing is required.
OCR prepPrepare scanned documents for better OCR
Improve recognition accuracy with better lighting, rotation, cropping, contrast and language choices.
PagesHow to extract pages from a PDF safely
Share only the pages a recipient needs, avoid accidental disclosure and review the final focused PDF.
ArchivePDF/A vs standard PDF: what is the difference?
Learn when archival PDF matters, what PDF/A does not solve and when a standard PDF is enough.
RecordsA practical PDF workflow for invoices and receipts
Organize financial PDFs, extract only needed pages, use OCR carefully and protect sensitive files.
PrivateHow to convert PDFs without uploading files
Understand browser-side conversion, what stays local and how to choose a private document workflow.
FixesCommon PDF conversion mistakes and how to avoid them
Avoid OCR, table, page order, file size and password mistakes before sending converted PDFs.
Choose the PDF workflow before choosing the tool.
Most PDF problems look similar from the outside: there is a file, and something needs to happen to it. The right workflow depends on what the file really contains. A digital PDF with selectable text should be handled differently from a phone scan. A spreadsheet export needs different settings from a signed form. A password-protected final copy should usually be the last step, not the first one.
The guides above are written around that decision. They explain when to use OCR, when to export PDF text to Word or Excel, when to turn images into a clean PDF, and when browser-side tools are the safer choice because the file can stay in the local session.
Common starting points
- If the page is a scan and you need text, start with the OCR guide.
- If the PDF has selectable text and you need editing or table cleanup, start with PDF to Word and Excel.
- If you have photos, receipts or paper scans, start with the image-to-PDF workflow.
- If you need to share the final file carefully, read the password protection guide before sending it.
- If the file is too large, remove pages and review image quality before lowering detail.
- If a workflow fails, check the common conversion mistakes guide before retrying.
- If the document is private, review the browser-based PDF tools guide before choosing any converter.
What vinniDocu is optimized for
vinniDocu focuses on everyday document work that can reasonably happen in the browser: merging and splitting PDFs, adding simple edits, protecting a final copy, extracting text, creating PDFs from images and converting common office files. The app is not meant to replace a full document management system. It is meant to make focused PDF tasks fast, understandable and private by default.
