Common PDF Tasks - Quick Answers

Find quick solutions to the most common PDF questions. Click any question to see the answer and recommended tools.

Use our Compress PDF tool with adjustable compression levels. Choose Low compression (80% quality) for minimal size reduction with highest quality, Medium (60%) for balanced results, or High (40%) for maximum compression. The tool intelligently optimizes images while preserving text clarity.

Our Merge PDF tool lets you upload multiple PDFs, reorder them by dragging and dropping, and combine them into a single file. You can also select specific pages from each document before merging. Perfect for combining invoices, reports, contracts, or any document collection.

Use our Protect PDF tool to add password protection and set permissions. You can require a password to open the document, restrict printing, copying, or editing. For multiple files, try our Batch Protect tool to secure many PDFs at once with the same password.

Yes! Our Split PDF tool allows you to extract individual pages or page ranges. You can select pages by number (e.g., 1-5, 10, 15-20), extract every nth page, or split by bookmarks. This is perfect for extracting specific sections from lengthy documents, reports, or ebooks.

Use PDF to Images to save each page as a JPG, PNG or TIFF file. For scanned documents, run OCR PDF first: it recognises the text so you can search and copy it.

Use our Sign PDF tool to add electronic signatures. You can draw your signature, upload an image, or type and choose a signature font. Place it anywhere on the document, resize it, and download your signed PDF. Perfect for contracts, agreements, and official documents.

Our Rotate PDF tool lets you rotate pages by 90, 180, or 270 degrees. You can rotate all pages at once or select specific pages to rotate individually. This is especially useful for scanned documents or PDFs with mixed orientations.

Absolutely! Our OCR PDF tool (Optical Character Recognition) converts scanned images into searchable text. OCR runs in your browser, so your file is not uploaded, and you can copy, search and edit the extracted text or download it as a TXT file. This works with photos of documents, screenshots, and scanned papers.

Use our Add Page Numbers tool to automatically number your PDF pages. Choose from various positions (top/bottom, left/center/right), customize the format (numbers, Roman numerals), and set the starting number. Perfect for reports, theses, and professional documents.

Our Rearrange Pages tool provides a visual interface to drag and drop pages into your desired order. You can also duplicate pages, delete unwanted pages, or create custom page sequences. Ideal for reorganizing scanned documents or creating custom document arrangements.
