All-in-One PDF & Image Toolkit

All-in-One PDF & Image Toolkit is a privacy-first document editor that runs entirely inside your browser. No file upload, no server, no account — your documents never leave your computer. Why use this extension Everything processes 100% on-device — nothing is ever uploaded anywhere. There's no sign-up, no subscription, and no hidden cost. Once loaded, it even works offline. It's essentially one tool that replaces the five or six different websites you'd normally need for document editing. Document tools Combine multiple files into one, split them apart, or reorder, delete, and duplicate individual pages. Fix sideways scans with rotation, trim unwanted margins with cropping, or shrink file size with compression — all without losing quality. Lock a file with a password, remove one you already own, or repair a corrupted file that won't open. You can also update title/author metadata, stamp in page numbers, add watermarks, place a hand-drawn or uploaded signature, type text directly onto a page, pull out embedded images, or run text recognition (OCR) to make scanned pages searchable and selectable. Format conversion Convert between PDF and image formats (JPG/PNG), turn a PDF into clean Markdown, or bring Word and Excel files into PDF form. Image tools Shrink image file sizes, convert photos to grayscale, remove a background automatically using on-device AI, or stamp a generated QR code onto a document. Privacy by design Every tool above runs locally in your browser tab using WebAssembly and on-device AI models. Nothing is sent to a server, there's no tracking or analytics on your file content, and no account is ever required. Whether you're a student, a professional, or just someone who needs to quickly combine two files, All-in-One PDF & Image Toolkit gives you a complete document toolkit without asking you to give up your privacy.
