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.

What PDF forms can I fill?▼

Any PDF with interactive AcroForm fields — text boxes, checkboxes, dropdowns, radio buttons, and multi-select lists. Scanned or image-only PDFs don't have fillable fields and will need OCR first.

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.
