Scan documents, receipts, and photos directly into multi-page PDFs with 4-point perspective keystone crop and Magic Color filters, password protect PDF files with bank-grade AES-256 or RC4 128-bit encryption and granular permissions (printing, copying, editing), draw, type, or upload custom signatures onto PDF pages, merge multiple PDF documents into a single file, split PDF pages by custom ranges, convert images (PNG, JPG, WEBP) to PDF, extract PDF pages as high-resolution images, or visually rotate and reorder PDF pages with drag-and-drop controls.

Frequently Asked Questions About PDF Utilities
Can I sign, merge, split, and organize PDF files without uploading them to a server?
Yes! All PDF operations on DwellixTools run locally in your web browser using WebAssembly and JavaScript PDF rendering libraries. Your confidential contracts, financial statements, and personal documents never leave your computer.
Does client-side PDF processing preserve document quality and vector text?
Yes. When merging or splitting PDFs, the underlying PDF vector text, embedded fonts, form fields, and metadata are preserved without lossy rasterization.
How do I reorder, rotate, or delete specific pages from a PDF?
Use our Organize PDF tool. It displays visual thumbnails of all pages in your document, allowing you to drag-and-drop to reorder, rotate pages 90 degrees clockwise, or delete unneeded pages before downloading.
Is there a file size limit for client-side PDF operations?
Because processing occurs in your local browser memory, file handling depends on your device’s available RAM. Most modern laptops and phones smoothly process PDF files up to 50 to 100 MB.
Can I preview my modified PDF before downloading it?
Yes. Every PDF tool includes a dedicated Preview button that lets you inspect your signed, merged, or organized document in a browser tab before saving the final file.
