Use Tool →PDF Tools
PDF tools built on ISO 32000 (PDF specification) using PDF-lib and PDF.js libraries. Merge, split, rotate, and compress PDFs with full standards compliance. Our compressor optimizes embedded images while preserving document structure. Text extraction uses PDF.js (Mozilla) for accurate content parsing. Electronic signatures use canvas-based drawing with cryptographic hashing. All processing happens locally—your documents never leave your device.
These tools cover the most common PDF workflows — combining multiple scans or documents into a single PDF for email, splitting large files to extract specific pages, adding page numbers before printing or sharing, and compressing image-heavy PDFs to meet email attachment limits (typically 25 MB for Gmail, 20 MB for Outlook). Whether you need to prepare a report, organize invoices, or share a presentation, each task takes just a few clicks.
The suite also includes professional features for more advanced needs. The PDF editor supports text annotation and highlighting for review workflows. The signature tool lets you draw or type electronic signatures and place them precisely on any page. The page number tool supports custom positioning, formatting, and starting number. PDF-to-image conversion renders each page as a high-resolution PNG or JPEG suitable for presentations or web use. All operations preserve document metadata, bookmarks, and hyperlinks where applicable.

Use Tool →Frequently Asked Questions
Are my PDF files uploaded to a server?
No. All PDF processing happens entirely in your browser using PDF-lib and PDF.js (developed by Mozilla). Your files are never uploaded to any server. This makes our tools safe for confidential documents, contracts, and sensitive business files.
What is the PDF standard?
PDF (Portable Document Format) was created by Adobe in 1993 and became an open ISO standard in 2008 as ISO 32000-1. The current version, ISO 32000-2 (PDF 2.0), was published in 2017. Our tools comply with the ISO 32000 specification, ensuring compatibility across all PDF readers and platforms.
How does PDF compression work?
PDF compression reduces file size by optimizing embedded images (the largest component in most PDFs), removing duplicate resources, and compressing data streams. Our compressor lets you choose a quality level that balances file size against image clarity, preserving text, fonts, and document structure.
What is the maximum PDF file size I can process?
Since all processing happens in your browser, the practical limit depends on your device's available memory. Modern computers can typically handle PDFs up to 100–200 MB without issues. For very large files, splitting them into smaller sections first can help avoid performance slowdowns. There is no server-side file size restriction because your files are never uploaded — everything runs locally using JavaScript and the PDF-lib library.
Are electronic signatures from the Sign PDF tool legally valid?
Our tool creates a visual signature image embedded in the PDF. In many jurisdictions, electronic signatures are legally recognized under laws such as the U.S. ESIGN Act (2000) and the EU eIDAS Regulation (2014) for most standard agreements, contracts, and consent forms. However, for documents requiring qualified electronic signatures — such as certain government filings, notarized documents, or regulated financial transactions — a certified digital signature service with identity verification may be needed. Consult local regulations for your specific use case.
