Understanding PDF documents
PDF is the world’s standard format for sharing documents because it looks the same on every device. But editing, converting or reorganising PDFs usually needs expensive software. Online PDF tools let you merge, split, compress, convert, protect and edit PDFs in your browser — quickly, securely and for free.
Common mistakes to avoid
- Uploading the wrong version of the file
- Not checking the page range before processing
- Skipping the preview before sharing the result
- Using a scanned PDF where selectable text is required (run OCR first)
