Feature Comparison
File Studio
100% Offline, On-Device Processing
This is the cornerstone feature that makes File Studio exceptional. Every single operation—from converting a HEIC file to merging a 100-page PDF—is executed locally on your Mac or Windows PC. Not a single byte of your data is uploaded to a remote server. This guarantees complete privacy and security for sensitive documents and also means your processing speed is limited only by your own hardware, with no internet latency.
Comprehensive PDF Toolkit
File Studio provides a full suite of essential PDF manipulations, all working offline. You can seamlessly merge multiple documents into one, split a large PDF into individual pages, reorder pages with a simple drag-and-drop, and rotate pages as needed. Crucially, it also handles document security, allowing you to remove passwords from PDFs you have the right to edit and to clean metadata, ensuring no hidden information leaves your device.
Advanced Image Conversion & Editing
Supporting over 20 formats, including modern types like HEIC, WebP, AVIF, and 14 different RAW camera formats, this tool eliminates compatibility headaches. But it goes far beyond simple conversion. You can resize, compress, crop, add watermarks, and even create image collages. The smart compression is particularly impressive, significantly reducing file size while intelligently preserving visual quality.
Powerful Batch Processing
This feature is a massive time-saver for professionals. Instead of processing files one by one, you can drag and drop an entire folder of images or documents. File Studio will then convert, resize, or compress all of them in a single, automated operation. This batch functionality, combined with offline processing, makes it incredibly efficient for preparing portfolios, client deliverables, or archiving projects.

Use Cases
File Studio
Securing Sensitive Legal Documents
As a freelancer or small business owner, you often handle signed contracts, tax forms, or client IDs. Instead of risking these documents on a random web converter, use File Studio to merge, split, or password-protect them entirely on your computer. You can redact information or clean metadata before sending, ensuring only the intended information is shared, with zero cloud exposure.
Preparing Photography Portfolios
Photographers can use File Studio to convert RAW files to universal JPEGs, batch-resize images for web or print specifications, and create cohesive PDF portfolios by merging selected images into a single document. Processing everything offline means your unpublished work remains completely confidential until you decide to share it.
Managing Personal Documentation
For anyone organizing their digital life, File Studio is perfect. Convert those unopenable HEIC photos from your iPhone to JPEGs for family albums, compress a folder of scanned receipts to save space, and combine multiple PDFs (like bank statements or manuals) into organized, yearly archives—all without ever uploading your private information.
Optimizing Content for Web & Email
Bloggers, remote workers, or anyone who needs to email images can use the smart compression tool to drastically reduce file sizes for faster uploads and downloads, while the format converter ensures compatibility with any platform. Creating a PDF from a series of images for a tutorial or compressing screenshots for a help desk ticket becomes a quick, offline task.
