LaiUse PDF tools handle the most common PDF operations: edit existing PDFs (add text, images, annotations), merge multiple PDFs into one, split a PDF into individual pages or sections, compress PDFs to reduce file size, and convert images (JPG, PNG) into PDF documents. Every PDF tool processes files locally in your browser using PDF.js — your documents never leave your device, which is the safest way to edit or merge confidential PDFs. No signup required, no watermarks added.
Convert images (JPG, PNG, WebP, GIF, BMP, TIFF) to PDF documents. Batch convert multiple images into a single PDF — all local.
Reduce PDF file size significantly while preserving readability. Choose high, medium, or low compression.
Edit PDFs in your browser — merge, split, rotate pages, and reorganize. No software installation needed.
Merge multiple PDF files into one. Drag to reorder pages before merging. All processing done locally in your browser — no uploads.
Split a PDF into separate files. Extract selected pages or split every N pages. All processing done locally in your browser.
