About Online2PDF
Online2PDF is a browser-based PDF converter and editor that has been developed and maintained by a single Austrian developer since 2007. It converts Word, Excel, PowerPoint, Publisher, OpenOffice, image and XPS files to PDF, exports PDFs back to Word, Excel, PowerPoint and JPG, and bundles 16 main features including merging, page extraction, compression, OCR, password removal and booklet creation into one single-page interface. There is no account, no signup and no paid tier — the service is entirely free and funded by Google AdSense ads plus voluntary donations.
Pros & Cons
Pros
- Genuinely free with no paywall, no signup and no watermark on output files — unusual among online PDF tools that gate batch processing or OCR behind subscriptions
- Unusually generous limits for a free tool: 150 MB per file, 200 MB total and up to 30 files in one batch
- Removes printing, copying and editing restrictions from PDFs automatically without requiring a password
- Options are combinable in a single pass — you can merge, compress, rotate, add a footer and apply protection in one conversion instead of chaining separate tools
- Strong file-privacy posture: HTTPS-only, uploads deleted immediately after conversion, and converted files purged after 90 seconds
Key Features
Conversion to PDF
Converts Word (DOC/DOCX), Excel (XLS/XLSX), PowerPoint (PPT/PPTX), Publisher, OpenOffice, XPS and image files (JPG, PNG, TIFF, GIF, BMP) into PDF, either merged together or as separate output files.
Merge files
Combines up to 30 selected files into a single PDF, either one after another or mixed alternately — useful for interleaving separately scanned front and back pages.
Export PDF to Office formats
Converts PDFs back into editable Word, Excel, PowerPoint or image files. Limited to 500 pages per conversion without OCR, or 100 pages with OCR enabled.
OCR for scanned documents
Makes scanned PDFs searchable via optical character recognition in 32 languages, with an additional Advanced OCR checkbox for difficult documents.
Remove PDF protection and unlock
Automatically strips printing, copying and editing restrictions without needing a password. Read-protected files still require the correct password, and DRM-protected files cannot be processed.
Protect PDF or change password
Applies a new password and sets authorization permissions for printing, copying and editing on the output file.

Best For
Merging scanned documents into one PDF
Combine up to 30 scans, images or Office files into a single PDF, using the mixed-alternately mode to interleave separately scanned odd and even pages back into correct order.
Unlocking restricted PDFs you already own
Strip printing, copying and editing restrictions from your own PDFs so they can be annotated or reused, without buying a full PDF editor license.
Making scanned archives searchable
Run OCR in any of 32 languages over scanned PDFs to turn image-only documents into searchable, selectable text for filing or research.
Shrinking oversized PDFs for email or upload
Use the compression tab to cut quality, resolution and color depth until a PDF fits under an attachment or portal size limit.
