Add digital signatures, initials, or handwritten marks. Legally valid and audit-ready for business documents.
Online PDF tools have become the default. But there's a real cost: your data moves through third-party servers, gets logged, potentially retained, and exposed to breaches. For contracts, tax returns, medical records, and payroll documents, this risk isn't acceptable.
Local processing changes everything. Your files never leave your device. No servers to compromise. No data retention policies to worry about. No Terms of Service burying what happens to your documents. You process, you own, you move on.

Whether you're a lawyer protecting client confidentiality, an accountant handling tax documents, a freelancer managing contracts, or someone who just doesn't want their family photos uploaded anywhere, PDF Toolkit respects your boundaries.
The shift toward local-first tools isn't about paranoia. It's about control. You get to decide what happens to your documents, who touches them, and where they go. That's not extreme. That's baseline professional practice.

It's that simple. No registration. No confirmations. No surprise emails trying to upsell you. Just the tool, and your files.
PDF Toolkit runs on open standards. No proprietary dependencies. The source code is available for audit. Use it as-is, fork it, integrate it into your workflow, or deploy it on your own infrastructure. It's built to work for teams who need transparency.
Because sometimes the best tool is one you can verify yourself.
Yes, 100%. Processing happens in your browser using WebAssembly. You can verify this by checking network activity in your browser's developer tools - you'll see zero file uploads to our servers. The only data sent is analytics (clicks, feature usage), which you can disable.
PDF Toolkit works offline after the first load. The entire app is cached in your browser. Open it again without internet and everything works exactly the same.
Yes. The web version works on iOS Safari and Android Chrome. A mobile app is planned.
PDF input and output. Image input (JPG, PNG, WebP, AVIF). Text extraction from scans. More formats coming based on user demand.
No hard limit, but processing speed depends on your device's RAM. Most computers handle files up to 500MB easily. Larger files may take longer.
Start for free. No installation. No signup. Open and use.
