Our Mission

ThinPDF was created with a single goal: provide powerful, free PDF tools that anyone can use without sacrificing their privacy. Too many online PDF services require accounts, harvest user data, or hide essential features behind paywalls. We believe document management should be simple, accessible, and private.

What We Offer

ThinPDF is a suite of free online tools for working with PDF documents:

Compress PDF

Reduce PDF file size by up to 90% without losing quality. Choose between regular and maximum compression levels depending on your needs.

Merge PDFs

Combine multiple PDF documents into a single file. Drag and drop to reorder pages before merging.

PDF to Word

Convert PDF files to editable Word documents while preserving formatting, tables, and layout.

Protect PDF

Add AES-256 password encryption to your PDF files to keep sensitive documents secure.

Unlock PDF

Remove password protection from encrypted PDFs when you have the correct password.

Our Principles

Privacy First

We don't collect personal data, require accounts, or track usage. All uploaded files are automatically deleted within 10 minutes of processing. We believe the best way to protect your data is to never store it.

Quality Results

We use industry-standard algorithms and libraries to ensure your documents maintain their quality after processing. Whether you're compressing, converting, or merging, the output meets professional standards.

Who We Are

ThinPDF is an independent project built by a small team of developers who were frustrated with existing PDF tools. Most online services either charge for basic features, require accounts to access downloads, or quietly collect and store user files far longer than necessary.

We decided to build what we wanted to use ourselves: a clean, fast, and genuinely free set of PDF tools that treat users with respect. ThinPDF is funded entirely by voluntary donations from users who find the tools useful.

Technology

ThinPDF is built with reliability and security in mind:

Server-side processing: All PDF operations happen on our servers, so your device doesn't need specialized software
HTTPS encryption: All file transfers are encrypted in transit
Automatic cleanup: Files are permanently deleted within 10 minutes
No database storage: We don't store file metadata, user information, or processing logs tied to individuals

Support the Project

ThinPDF is free to use and will remain so. If you find our tools helpful, you can support continued development by:

Buying us a coffee to help cover hosting costs
Sharing ThinPDF with friends and colleagues who work with PDFs
Requesting features you'd like to see added
