FAQ
Answers to common questions
Is LocoPDF really free? +
Yes! Core tools like merge, split, compress, and rotate are completely free with no limits. Advanced and interactive tools get 50 free uses each. Upgrade to Pro for unlimited access plus batch processing and saved signatures.
Do you upload my files? +
Never. All processing happens locally in your browser using JavaScript. Your files never leave your device.
What PDF tools are available? +
Is LocoPDF safe for sensitive documents? +
Yes. Since files never leave your device, LocoPDF is safe for confidential, legal, medical, and financial documents.
Can I fill out PDF forms? +
Yes! The Fill PDF Forms tool detects text fields, checkboxes, dropdowns, and radio buttons in your PDF and lets you fill them in directly in your browser. You can optionally flatten the form before downloading.
What is batch processing? +
Batch processing is a Pro feature that lets you drop multiple PDF files and process them all at once — for example, compressing, watermarking, or signing 50 documents in one go with a progress bar and ZIP download.
What are saved signatures? +
Saved signatures is a Pro feature that stores your signatures locally in your browser (IndexedDB) so you can reuse them across documents. Name them, manage them, and apply with one click — still 100% private.
Which tools are free vs Pro? +
Core tools (merge, split, compress, rotate & reorder) and convert tools (PDF to image, image to PDF, PDF to Word) are completely free with no limits. Advanced and interactive tools (watermark, remove password, sign, annotate, fill forms) get 50 free lifetime uses each. Pro unlocks unlimited usage, batch processing, and saved signatures.
Why upgrade to Pro? +
Pro unlocks three power features designed for people who work with PDFs regularly:
- ⚡ Batch Processing — Drop dozens of PDFs and compress, watermark, or sign them all at once. Each file shows its own progress bar, and you download everything as a single ZIP.
- 🔗 Pipe Mode — Chain tools together without re-uploading. Compress a PDF, then immediately pipe the result to the Sign tool or Watermark tool. One continuous workflow, zero re-uploads.
- ✍️ Saved Signatures — Store multiple signatures locally in your browser. Name them, manage them, and apply to new documents with one click — still 100% private.
Plus unlimited usage across every tool, no caps.
