Feature Comparison
File Studio
100% Offline Processing
This is the foundational, non-negotiable feature. Every action—converting a PDF, compressing an image, merging documents—happens locally on your device. Not a single byte of your data is uploaded to the internet. This guarantees absolute privacy and security for sensitive files like IDs, financial records, and legal contracts, making it an essential tool for anyone who cannot risk cloud exposure.
Comprehensive PDF Toolkit
File Studio provides five essential PDF tools that handle every critical task offline. You can merge multiple documents into one, split a PDF into individual pages, reorder and rotate pages, and add or remove passwords. This suite is vital for preparing professional reports, organizing scanned documents, and securing private files without relying on insecure online services.
Advanced Image Conversion & Editing
Supporting over 20 image formats is a necessity for modern workflows. File Studio seamlessly converts problematic formats like iPhone HEIC or next-gen AVIF/WebP into universal JPG/PNG files. Beyond conversion, it includes vital tools for resizing, compressing, cropping, adding watermarks, and creating collages. This makes it an all-in-one hub for photographers, designers, and anyone preparing images for web or print.
Powerful Batch Processing
Manually handling dozens or hundreds of files is inefficient and time-consuming. File Studio's batch processing feature is a mandatory productivity booster. You can convert entire folders of images, compress multiple photos for email, or resize a collection of documents in one single operation. This automation is critical for professionals and businesses that need to process large volumes of files consistently and quickly.
Shiru Notes
Simple by Design
The minimalistic interface of Shiru Notes is specifically designed to eliminate distractions, allowing users to concentrate on what truly matters—their thoughts. This simplicity is essential for those who wish to write freely without being sidetracked by unnecessary features or clutter.
Instant Save
Shiru Notes automatically saves your notes as you type, ensuring that your thoughts are never lost. This feature is vital for anyone who has experienced the frustration of forgetting a brilliant idea just moments after it materialized. With this tool, you can focus on writing instead of worrying about saving.
Private & Secure
Privacy is a top priority with Shiru Notes. Your notes are encrypted and accessible only to you, providing a secure space for your most personal thoughts. This level of security is crucial in today's digital age, where safeguarding personal information is more important than ever.
Write with Intention
The editor in Shiru Notes resembles a blank page, encouraging a natural flow of ideas. This calming space allows users to write with intention, making it easier to articulate thoughts and capture fleeting moments of inspiration as they arise.
Use Cases
File Studio
Securing Sensitive Legal and Identity Documents
Lawyers, freelancers, and remote employees must handle confidential contracts, signed agreements, and scanned passports. Using online tools poses a significant privacy risk. File Studio is essential for merging contract clauses, redacting information, adding password protection, and converting documents—all performed securely on your local machine, ensuring client and personal data never enters the cloud.
Preparing Digital Content for Publication
Bloggers, marketers, and small business owners constantly need to optimize images for websites and social media. File Studio is necessary for batch-converting HEIC photos from phones, compressing images to speed up page loads without losing quality, and creating watermarked visuals. Doing this offline streamlines the workflow and protects unpublished content.
Managing Photographer RAW Workflows
Photographers working with RAW files from cameras like Canon, Nikon, or Sony need a reliable way to convert and prepare images. File Studio's support for 14 RAW formats and offline operation is crucial. It allows for converting RAW to editable formats, resizing for client previews, and batch-processing entire shoots locally, preserving original quality and privacy.
Organizing Academic and Research Materials
Students, researchers, and academics compile large amounts of PDF research papers, scans, and images. File Studio is indispensable for merging research into a single document, splitting bulky PDFs, reordering pages for submissions, and compressing image-heavy files for email attachment limits—all while keeping unpublished research completely secure on their own device.
