How do I merge multiple PDF files into one?

Upload or drag-and-drop multiple PDF files into the merger tool. Arrange them in your desired order by dragging files up or down in the list. The tool shows thumbnails of each PDF's first page for easy identification. Once ordered, click 'Merge PDFs' and the tool combines all files into a single PDF document, preserving each file's content, formatting, and page structure. This is perfect for combining invoices, contracts, reports, or any collection of separate PDFs into one organized document. All processing happens in your browser, so your files never leave your device.

Can I split a PDF into separate pages or sections?

Yes! Upload your PDF and choose how you want to split it: extract specific page ranges (e.g., pages 1-5, 10-15), split every X pages (e.g., every 3 pages creates new PDFs), extract individual pages as separate files, or split at specific page numbers. The tool shows page previews so you can see what you're extracting. This is useful for separating chapters from a book, extracting relevant sections from long reports, or creating individual documents from batch-scanned files. Each split PDF maintains the original quality and formatting of the source document.

How can I reduce PDF file size without losing quality?

PDF compression works by optimizing images (reducing resolution while maintaining visual quality), removing duplicate embedded fonts, eliminating metadata and hidden data, and recompressing the PDF structure. You can typically reduce file size by 40-70% with minimal quality loss. Choose compression level: maximum compression (smallest file, some quality loss—good for sharing), balanced (moderate size reduction with better quality—recommended), or lossless (only removes redundant data, no visual changes). Compression is essential for emailing PDFs with attachment size limits, reducing storage costs, or improving website load times when PDFs are downloadable.

Are my PDF files secure when using online PDF tools?

Absolutely! Our PDF tools process everything locally in your browser using JavaScript and WebAssembly. Your PDF files are never uploaded to any server, transmitted over the internet, or stored anywhere except temporarily in your browser's memory during processing. This makes it completely safe to work with sensitive documents like contracts, financial statements, medical records, or confidential reports. Once you close the browser tab or download the processed PDF, all data is immediately cleared from memory. No server logs, no data retention, complete privacy. Always verify tools claiming client-side processing by checking network activity in browser developer tools.

What PDF conversions are supported?

Common PDF conversions include: PDF to images (PNG, JPG—useful for presentations or web display), images to PDF (combine multiple photos into a document), PDF to Word (editable DOCX format), Word to PDF (preserve formatting), PDF to Excel (extract tables), PDF to PowerPoint, and HTML to PDF. When converting from PDF, text extraction quality depends on whether the PDF contains actual text or scanned images (OCR may be needed for scans). Converting to PDF preserves formatting across all platforms—a Word document looks identical as a PDF on any device. Choose conversion based on your use case: edit content (to Word), extract data (to Excel), or share with formatting locked (to PDF).

Can I rearrange, rotate, or delete PDF pages?

Yes! PDF editors let you manipulate page order and orientation. Rearrange pages by dragging thumbnails to new positions—perfect for fixing incorrectly ordered scans or reorganizing content. Rotate pages 90°, 180°, or 270° to fix orientation issues from scanning or mobile photos. Delete unnecessary pages to remove blank pages, unwanted content, or reduce file size. Some tools also support duplicating pages, inserting blank pages, or splitting pages. Changes are non-destructive until you export—you can undo and restart. This is essential for preparing professional documents from raw scans or combining multiple sources with different orientations.

What's the maximum PDF file size that can be processed?

Since PDF tools run in your browser, the limit depends on your device's available memory (RAM). Most modern computers with 8GB+ RAM can handle PDFs up to 100-200MB (hundreds of pages) without issues. Mobile devices with 4GB RAM may struggle with files over 50MB. Very large PDFs (500MB+, thousands of pages) might cause browser slowdowns or crashes. For huge files, consider splitting into smaller sections first, processing each, then merging. Desktop PDF software handles larger files better but requires installation. The browser-based approach provides instant access without downloads, making it perfect for typical PDF tasks (contracts, reports, invoices) which are usually under 50MB.

How do I extract specific pages from a PDF?

Upload your PDF and the tool displays page thumbnails with numbers. Select specific pages by clicking checkboxes or entering page ranges (e.g., 1-5, 10, 15-20). The tool creates a new PDF containing only the selected pages while maintaining original quality, bookmarks, and links. This is useful for extracting relevant chapters from books, separating signed contracts from multi-page agreements, creating custom document compilations, or sharing specific sections without exposing the entire file. Extracted pages retain all formatting, images, and text exactly as in the original, making the new PDF indistinguishable from a natively created document.

Why do some PDFs lose formatting when converted to Word?

PDF to Word conversion quality depends on PDF structure. PDFs created from Word preserve formatting well because they contain proper text and structure metadata. Scanned PDFs or image-based PDFs require OCR (Optical Character Recognition) to extract text, which may misinterpret fonts, colors, or layout. Complex PDFs with custom fonts, multi-column layouts, text boxes, or embedded graphics are harder to convert perfectly—the converter attempts to recreate layout using Word elements, but complex designs may shift. For best results: use high-quality source PDFs with actual text (not scans), accept that some manual cleanup may be needed for complex layouts, or consider editing the PDF directly instead of converting.

Can I password protect or encrypt PDFs?

PDF encryption adds password protection to prevent unauthorized viewing or editing. Set an open password (required to view the PDF) and/or a permissions password (restricts printing, copying, or editing). Encryption uses AES-128 or AES-256 bit encryption for strong security. Protected PDFs require the password to open in any PDF reader. This is essential for sharing sensitive documents (contracts, financial data, personal information) via email or file sharing. Note: password protection only secures the PDF itself—if someone has the password, they have full access. For maximum security, combine password protection with secure file transfer methods and strong, unique passwords. Never share passwords through the same channel as the PDF.
