How do we guarantee the security of your data?
Most online PDF services require uploading your private documents to external servers for processing. PDFCapsule processes your files entirely locally in your browser. No data ever leaves your machine, guaranteeing absolute privacy compliant with GDPR. It is free, instant, and works 100% offline.

Frequently Asked Questions (FAQ)
Everything you need to know about security, privacy, and how PDFCapsule works.
PDFCapsule is a suite of PDF document tools that operates 100% client-side, directly within your browser's RAM. Unlike traditional online PDF converters that upload your private files to remote external servers, exposing you to potential security risks and data breaches, with PDFCapsule no file ever leaves your computer. This guarantees absolute privacy, ideal for processing sensitive or corporate data in full compliance with GDPR.
Yes, absolutely! Thanks to PWA (Progressive Web App) technology and a Service Worker, PDFCapsule is saved in your device's local cache on first load. You can then disconnect from the Internet, enable airplane mode, and continue merging, splitting, compressing, or signing your PDFs completely offline.
No, we do not apply any size limits on uploaded files or daily operations. Since processing happens locally on your computer using your device's hardware resources (via high-performance WebAssembly and JavaScript), we do not consume server bandwidth. You can merge or compress very heavy documents without paying any subscription or registering an account.
No. PDFCapsule non utilizza cookie di profilazione, pixel di tracciamento di terze parti (come Google Analytics) o pubblicità mirata. Gli unici dati raccolti sono log di rete generici e temporanei a livello del server di hosting (Amazon Lightsail) per scopi di stabilità e sicurezza informatica, come stabilito dal GDPR. La tua navigazione e i tuoi file restano privati al 100%.
PDFCapsule offers a complete suite for PDF document management, including: merging and combining files, visual page splitting and extraction, local compression to reduce file size, format conversion (to and from JPG, Word, PowerPoint, Excel, HTML), repair of damaged PDFs, text extraction via local OCR, rotation, page numbering, adding protective watermarks, freehand digital signing, redaction of sensitive data by blacking out, and password protection.
How do we guarantee your privacy?
No tricks, no servers. Here is a visual explanation of how your data is processed.
Local Reading
Your PDFs are loaded into your browser's temporary RAM as binary fragments (ArrayBuffer). They never reach any server.
Client-Side Processing
The page's JavaScript engine (`pdf-lib`) unpacks files, extracts pages, and assembles or compresses them, entirely using your device's CPU.
Direct Saving
The new PDF is downloaded via a locally generated blob URL (`blob:null/...`). It is essentially a memory transfer internal to your computer.
Want proof? Try it Offline!
Load this page, turn off your Wi-Fi or internet connection completely, and try merging or compressing files. You will see it works perfectly even without a network.
