Frequently Asked Questions

Is this PDF tool really free?▼
Yes. Every PDF tool on iluv.tools is completely free. No signup, no account, no payment. Everything runs in your browser.
Are my PDF files uploaded to a server?▼
No. All PDF processing happens locally in your browser using the pdf-lib and PDF.js libraries. Your files never leave your device.
Do these PDF tools work offline?▼
Basic PDF tools (merge, split, compress, rotate, sign, watermark, protect, unlock, add page numbers, edit metadata, flatten, grayscale, crop, delete pages) work completely offline after the page loads. AI-powered tools like smart compression and PDF to Word require an internet connection.
Is there a file size limit?▼
Browser-based tools handle files up to ~100MB smoothly. Larger files may be slower depending on your device. For very large PDFs, try splitting them first, processing the parts, then merging.
Can I use these on mobile?▼
Yes. All PDF tools work on mobile browsers (iOS Safari, Android Chrome). Desktop is recommended for large files, but everything is functional on mobile.
