About PDF Tools
PDF tools let you merge, split, compress, and convert PDF files entirely in your browser using Mozilla's PDF.js library and pdf-lib. No files are uploaded to any server—your documents stay private and secure on your device.
The Privacy Problem with Traditional PDF Tools
Most online PDF services require you to upload your documents to their servers. This is a serious privacy risk for tax documents, contracts, medical records, and legal files. Browser-based tools eliminate this risk entirely—your PDF is processed in your device's RAM and never transmitted over the network.
PDF Structure: What Makes PDFs Large
PDFs can contain embedded fonts, high-resolution images, metadata, color profiles, and object streams. Compressing a PDF means stripping redundant metadata, downsampling images, and removing unused objects. Our PDF compressor applies these techniques client-side to reduce file sizes by 30–70% without visual degradation.
When to Use PDF vs Other Formats
Use PDF for documents that must maintain their exact layout across all devices: contracts, invoices, forms, and reports. Use Word/Google Docs for collaborative documents that need to be edited. Use PNG or JPG when you need to embed a document page as an image in a website or presentation.
Frequently Asked Questions
Is it safe to use online PDF tools?
Our PDF tools use pdf-lib and PDF.js to process files entirely in your browser. No files are ever uploaded to our servers. Your documents remain completely private.
How much can I compress a PDF?
Compression results vary by content. PDFs with large embedded images can be reduced by 50–80%. PDFs with mostly text and vector graphics may only reduce by 10–30%.
Can I merge more than two PDFs?
Yes. Our PDF merger allows you to combine multiple PDF files in any order and merge them into a single document.
