Privacy & Security
Where do my files go?
Your files never leave your device. All processing happens entirely in your browser. Nothing is uploaded to our servers or stored anywhere.
Is my data safe?
Completely safe. Since all processing happens locally, your data never leaves your device. We don't collect, store, or track any user information.
Do you track me?
We don't track individual users. We only see anonymized usage statistics through Google Analytics to understand which tools are most popular.
What about GDPR/Privacy regulations?
Since we process files locally and don't collect personal data, GDPR and similar regulations are naturally satisfied. No data = no privacy concerns.
How to Use
Which tools should I use for my task?
Each tool page includes a detailed 'How to Use' section with step-by-step instructions, tips, and FAQ. Start there for specific guidance.
Can I use multiple tools in sequence?
Yes. For example, compress an image, convert it to PDF, then merge multiple PDFs. Each tool works independently.
What file formats are supported?
It depends on the tool. PDF tools support PDFs, image tools support JPG/PNG/WEBP, video tools support MP4/WebM, audio tools support MP3/WAV/FLAC/OGG, and more.
Is there a file size limit?
Technically no hard limits, but very large files (100MB+) may be slow due to browser memory limits. For most files, you won't encounter limits.
Quality & Performance
Will my files lose quality?
It depends on the tool. Compression tools may reduce quality slightly (adjustable), while conversion and formatting tools preserve quality perfectly.
Why is processing slow sometimes?
Processing speed depends on file size and your computer's performance. Large files take longer. Modern computers handle most files instantly.
Can I batch process multiple files?
Most tools support adding multiple files. Check the specific tool page for batch capabilities.
What browsers are supported?
All modern browsers work: Chrome, Firefox, Safari, Edge. ZapFiles requires JavaScript enabled.
Technical
Why does processing happen in my browser?
Browser-based processing means zero server costs, instant results, complete privacy, and no uploads. It's the best approach for file tools.
What technology powers ZapFiles?
Built with Next.js (React framework) and WebAssembly-powered libraries for efficient browser-based processing.
Is ZapFiles open source?
ZapFiles is currently closed source, but the platform may be open-sourced in the future.
