Comment ça marche

Offline File Tools uses WebAssembly and modern browser APIs to process your documents entirely on your device. Unlike other file tools online that upload your sensitive documents to remote servers, your files never leave your computer.

Choisissez votre outil
Select from 8 free PDF tools — merge, split, compress, rotate, convert and more.
Chargez votre fichier
Drag and drop or click to select. Files are read directly by your browser — nothing is sent anywhere.
Traitez localement
Your browser uses pdf-lib and PDF.js (WebAssembly) to process the file with full CPU/RAM power.
Téléchargez instantanément
The result is downloaded directly to your device. No waiting for server uploads or downloads.

Pourquoi choisir Offline File Tools ?

There are many online file editors out there. Here's what makes Offline File Tools different from iLovePDF, Smallpdf, and other competitors.

Confidentialité sans envoi
Your documents contain sensitive data. Unlike most PDF tools online, we never touch your files — processing is 100% local.
Très rapide
No upload time, no queue, no server latency. Processing speed is limited only by your own CPU and RAM — usually seconds.
100 % gratuit, toujours
No paywalls, no subscriptions, no "pro plan". All 8 tools are completely free with no registration required.
Fonctionne hors ligne
Once the page loads, you can disconnect from the internet and tools will still work. Great for confidential documents.
Aucune limite de taille
Server-based tools cap files at 50–200MB. Since we process locally, you're only limited by your device's available RAM.
Multiplateforme
Hors ligne on any device with a modern browser — Windows, Mac, Linux, iPhone, Android. No app download needed.

Tous les outils PDF gratuits expliqués

Fusionner des PDF en ligne — gratuit

Combine multiple PDF documents into a single file instantly. Our free merge PDF tool lets you drag and reorder files before combining. Perfect for combining reports, contracts, invoices, or presentation slides. No aucune limite, no watermarks, and unlike competitors — no upload required.

Diviser un PDF — extraire des pages gratuitement

Extract specific pages or page ranges from any PDF. Enter ranges like "1-3, 5, 7-9" to get exactly the pages you need. Multiple extracted sections are packaged into a ZIP for easy download. Great for extracting chapters from e-books or isolating specific documents from a combined report.

Compresser un PDF — réduire la taille en ligne

Reduce PDF file size without losing quality. Our compression tool uses object stream optimization to shrink PDFs efficiently. Useful for emailing PDFs, uploading to portals with aucune limites, or saving storage space. Typical compression rates range from 10%–60% depending on the content.

Faire pivoter des pages PDF — en ligne, gratuit

Rotate all pages or select odd/even pages by 90°, 180°, or 270°. Fix scanned documents that came out upside down or sideways. The rotation is embedded permanently into the PDF — it won't revert when opened in other viewers.

Convertir un PDF en images (PNG/JPG)

Render every page of a PDF as a high-quality PNG or JPEG image. Choose from normal (96dpi), high (144dpi), or maximum (216dpi) resolution. All pages are bundled into a ZIP file for download. Powered by Mozilla's PDF.js — the same engine used in Firefox.

Convertir des images en PDF

Combine multiple JPG, PNG, or GIF images into a single PDF document. Each image becomes one page, sized to fit. Useful for creating PDF portfolios, digitizing photos, or compiling scanned documents into a single shareable PDF.

All processing happens entirely in your browser using WebAssembly and JavaScript. Your files are never uploaded to any server and never leave your device. The source code is inspectable — open DevTools and watch: no network requests are made when processing your files.
Yes, all tools are completely free with no registration, no watermarks, and no aucune limites. The site is supported by non-intrusive display advertising. We will never introduce paywalls for core functionality.
Since processing happens in your browser, the limit depends on your device's available RAM. Most modern computers with 8GB+ RAM can handle files up to 500MB or larger without issues. There is no artificial server-side cap.
No account, no installation, no plugins. Offline File Tools works directly in any modern web browser including Chrome, Firefox, Safari, and Edge on both desktop and mobile.
The key difference is privacy. iLovePDF and Smallpdf upload your files to their servers for processing — your documents pass through third-party infrastructure. Offline File Tools processes everything locally in your browser, so sensitive legal, financial, or personal documents never leave your device. We're also fully free with no file size paywalls.
Yes! Once the page has fully loaded (including the JavaScript libraries), you can disconnect from the internet and all tools will continue to work. This makes it suitable for processing confidential documents in air-gapped environments.
