Free Online PDF Tools — No Upload Required

OptiDrop's PDF tools let you merge, split, compress, watermark, and convert PDF files entirely in your browser. Unlike other online PDF services, OptiDrop processes everything locally using JavaScript — your files are never uploaded to any server. This makes it completely safe for confidential documents like contracts, financial reports, legal papers, and personal records.

Whether you need to combine multiple PDFs into one, extract specific pages, reduce file size for email attachments, add page numbers for professional documents, or convert PDFs to images, OptiDrop has you covered. Every tool is free with no sign-up, no watermarks, and no file size limits beyond your device's available memory.
