PDF tools online

Is work done locally in the browser?

Most operations run in your browser and files remain on your device. Some advanced features are placeholders or require additional libraries. See each tool for specifics.

Why are some conversions placeholders?

Some PDF operations need heavy third-party libraries (parsing, manipulating page objects). We provide a consistent UI and implement safe features (like image → PDF) directly; other operations show TODOs in code so developers can integrate preferred libraries later.

Are my files uploaded?

No uploads by default. All processing occurs in your browser. If you use external export/upload features later, you’ll be informed and prompted.

All-in-One PDF Tools: Simplify Your Digital Workflow

Managing PDF files has become an everyday task for students, professionals, and businesses. Whether you need to merge multiple reports, compress large documents for email, or convert PDFs into editable formats, reliable online PDF tools save time and effort. Platforms like PDFHero offer a privacy-first, browser-based solution so users can perform these tasks quickly without installing heavy software.

Why Use Online PDF Tools?

PDFs are universal because they preserve formatting across devices and operating systems. However, working with PDFs isn’t always straightforward—editing, splitting, or converting them requires special tools. Online utilities eliminate the need for bulky desktop programs and instead run directly in your browser. This ensures faster access, compatibility across devices, and a smooth workflow even when you’re on the move.

Security and Privacy Matters

One major concern users have is the safety of their data. Many online PDF platforms ensure that files are processed client-side, meaning your documents never leave your browser. This is particularly important for confidential files such as contracts, invoices, or personal IDs. Reputable services highlight transparency in their privacy policies, which makes them more trustworthy.

Everyday Use Cases

Teachers can merge exam sheets and assignments into one document.
