🚀 Exclusive Feature

Introducing Smart Workspace

A browser workspace for keeping files between supported tool operations.

AdreTools revolutionizes online document processing by introducing the Smart Workspace. Say goodbye to the endless cycle of downloading intermediate files, littering your local "Downloads" folder, and re-uploading them to the next tool. Our highly intelligent, fully local virtual pool acts as an integrated development environment (IDE) specifically engineered for your PDF files and images.

Seamless Tool Interconnectivity

The output of one tool (e.g., extracting images from a PDF) is instantly deposited into your virtual Workspace. With a single click, you can inject those results into another tool (e.g., Image to PDF Converter) without ever leaving the platform or triggering a local PC download.

Dynamic AI-Powered Sorting

Our system automatically parses, categorizes, and organizes your files into a sleek, masonry-grid interface. Whether you are generating PNGs, merging DOCX files, standardizing irregular PDF page sizes (A4/Letter), or compressing PDFs, the Smart Workspace intelligently categorizes them on the fly.

Workspace storage stays in your browser

Smart Workspace stores files in browser IndexedDB. This storage can persist after closing the browser. Remove files with the workspace controls or clear site data. Sending a workspace file to a server-based tool uploads that selected file; workspace storage does not change that tool's processing location.

💬 Frequently Asked Questions (FAQ)

Yes, absolutely. We prioritize your data security. Unlike traditional online PDF editors that require you to upload your sensitive files to an unknown server, AdreTools utilizes advanced modern browser technologies (like WebAssembly and pdf-lib). This means that for almost all tools, your PDF file is processed entirely on your own device's memory. It never touches our servers.

No installation is required. AdreTools is a 100% web-based platform. You can access all our PDF tools directly through your web browser (Chrome, Safari, Firefox, Edge) on any device, completely free of charge.

Since processing happens locally in your browser, the only real limit is your device's memory (RAM). However, for optimal performance and to prevent your browser from freezing, we generally recommend keeping individual files under 100MB-200MB depending on your computer's speed.

Yes! All the core tools including PDF Splitting, Merging, Editing, Watermarking, Rotating, Resizing, and Conversions are completely free to use. No account is required for these workflows. Resource and request limits can apply; availability and limits depend on the selected tool.

It's incredibly simple! Just navigate to our "Image to PDF" tool, drag and drop your JPG, PNG, or WEBP images into the workspace. You can easily drag to reorder them, adjust margins and page sizes, and finally click the download button to generate your new PDF instantly.

Yes. Our Watermark PDF tool allows you to place text (with custom fonts, colors, and opacity) or an uploaded image logo across any specific page range you define. You can also use the 'Mosaic' feature to tile the watermark across the entire background of the document for maximum security.

Absolutely! Our new Resize PDF tool allows you to instantly standardize all pages within a PDF to a uniform format (A4, Letter, A3, etc.). By using the "Smart Fit" strategy, your text and images are scaled proportionately without any distortion or data loss.
