When to merge, split and convert PDFs

Merge, split, reorder, watermark and convert documents in the browser. Check a small sample before converting complex files.

How to use

  1. Choose an operation and import the corresponding file format.
  2. Preview or export a few pages and check pagination, fonts and content.
  3. Save after confirming the output meets your needs.

Example and expected result

Scenario: import two short PDFs → merge → review output page order.
Text extraction: an image-only scan may contain no extractable text.

Capabilities and limits

  • No general OCR is provided, so scans may not become editable text.
  • Complex Word/Excel/PPT layouts are approximations; signatures, forms and metadata may not survive.

Troubleshooting

Check for encryption or corruption on read errors. For missing or disordered text, check whether the source is a scan and review layout complexity.

Data processing and storage

Most conversion work runs in the browser. Remote images referenced by documents may trigger resource requests. Exports use local downloads.
