# EditPDFKit

> 100% Free, Private In-Browser PDF & Image Editing Suite

EditPDFKit is an ultra-fast web application for editing, converting, signing, compressing, and managing PDF and image files directly inside the browser. Most tools run entirely client-side with zero server uploads. PDF-to-Word conversion requires structural layout parsing and is processed in volatile memory on an ephemeral serverless function, never written to disk or retained; see https://www.editpdfkit.com/security for full detail.

- [How to Convert PowerPoint (PPTX) Slides into Clean PDF Handouts](https://www.editpdfkit.com/blog/convert-powerpoint-presentations-to-pdf-handouts): Sharing raw PowerPoint files (.pptx) with clients or students frequently leads to missing custom font warnings, shifted text boxes, and formatting errors on devices without Microsoft Office installed.

- [How to Rotate Sideways Photos & Scanned Certificates Upright Permanently](https://www.editpdfkit.com/blog/rotate-sideways-photos-upright-permanently): Smartphone cameras frequently misread orientation sensors, causing photos taken in portrait mode to save as sideways landscape images.

## Core Architecture & Privacy Guarantees

- **In-Browser Execution, With One Documented Exception**: Every tool except PDF-to-Word processes files using WebAssembly, Canvas 2D, and Web Workers directly on the user device, with no upload of any kind. PDF-to-Word is the single exception: structural layout parsing requires it, so the file is streamed to an ephemeral serverless function, converted in volatile memory, and streamed back — never written to disk, logged, or stored after the request completes.
- **Offline Capability (PWA & Service Worker)**: Once loaded, the platform keeps working offline. Users can merge, compress, protect, convert, and edit documents without an active internet connection — PDF-to-Word is the one tool that still needs a connection, because it runs on the serverless function described above.
- **Universal Tool Chaining**: Files cached in the local IndexedDB Privacy Vault can be immediately passed into another tool (e.g. compressing multiple PDFs and directly merging them) with zero re-uploading or intermediate downloads.
- **Zero Registration & Unlimited Free Usage**: All tools are fully available without paywalls, subscriptions, or watermarks.
- **Full Markdown & Machine Documentation**: Full detailed documentation is available at [https://www.editpdfkit.com/llms-full.txt](https://www.editpdfkit.com/llms-full.txt).
