Why Nelstack
Built for sensitive, real-world documents
Nothing is uploaded
Documents are processed on your device. Bank statements, IDs and contracts never touch a server.
No caps or paywalls
No file-count limits, no daily quota and free OCR — features others keep behind a premium plan.
Protected PDFs welcome
Type the password once and any tool can work on an encrypted PDF — unlocked on your device.
Chain tools together
Send the result straight into the next tool: merge, then compress, then protect — no re-uploading.
Private AI
Summaries and translations run on-device with your browser’s built-in AI or open models.
Works offline once loaded
After first use, engines are cached, so most tools keep working on a poor connection.

PDF Tools FAQ
Are these PDF tools really free?
Yes. Every tool is free with no signup, no watermark and no daily limit. Files can be up to 200 MB each; the practical limit is your device’s memory.
Are my PDFs uploaded to a server?
No. Every tool runs inside your browser. Engines such as Ghostscript, qpdf, OCR and AI models are downloaded to your device on first use and then run locally — your documents are never sent anywhere.
How is this different from iLovePDF or Smallpdf?
Those services upload your file to their servers and limit free use. Here the work happens on your own device, so sensitive documents like bank statements, IDs and contracts stay private, and there are no file-count caps or premium-only OCR.
Can I use several tools on the same file?
Yes. After any tool finishes, choose “Continue with…” to send the result straight into the next tool — for example merge, then compress, then protect with a password.
Do the tools work on phones?
Yes. Every tool works in modern mobile browsers. Scan to PDF uses your phone camera directly, with no app to install. Heavy jobs on very large files are faster on a computer.
