PDF Tools
Split, merge, compress, without uploading.
4 tools · all run in your browser
Merge multiple PDFs into one, split a PDF into individual pages or page ranges, compress a scanned document to a fraction of its original size, or assemble a batch of images into a single PDF — all without uploading your files to a third-party server. Everything runs in your browser using PDF-lib, a pure JavaScript library that processes PDFs on your device.
Why this matters: PDFs routinely contain sensitive information — tax documents, medical records, signed contracts, pay stubs. Dragging one into a random "merge PDF" website uploads it to a server you know nothing about, often stores it for analysis or ad targeting, and in some cases exposes it to third parties. Browser-side processing means the file never leaves your device.
File size note: browser-side compression reduces size by re-encoding scanned-image PDFs (often 60-80% reduction on scanned docs). For text-based PDFs (those with actual text, not scanned images), size reduction is smaller because the text is already efficient. For large files over 100 MB, processing may take a few seconds — the progress bar shows what is happening.
All pdf tools
- Compress PDFShrink a large PDF right in your browser. Great for scanned documents and photo-heavy PDFs — pick a quality level and download a smaller file. No upload.
- Images to PDFTurn one or more images into a single PDF file. JPG, PNG, and WebP supported. Reorder the pages, pick page size and fit mode, download — all in your browser.
- Merge PDFsMerge two or more PDF files into a single document. Reorder pages, remove unwanted pages, and download the result — all in your browser. Nothing is uploaded.
- Split PDFSplit any PDF into individual pages or custom ranges. Extract just the pages you need, then download as separate PDFs. Runs in your browser — no upload.
Frequently asked
Yes — our PDF Merger runs entirely in your browser using PDF-lib. Select your files, reorder them by dragging, click Merge. The combined PDF downloads to your device. No upload, no account, no file size limit beyond what your device RAM can hold.
Yes — use PDF Splitter. Enter the page ranges you want (e.g., 1-3, 7, 10-15) and download just those pages as a new PDF. Useful for extracting one chapter from a book or one section from a legal doc.
Depends heavily on the content. A scanned-image PDF (the most common large type) can often be compressed 60-80% by reducing image resolution. A text-based PDF (native PDF, not scanned) might compress 5-20% since the text is already efficient. Our compressor shows before/after file size.
No. Files are loaded into browser memory, processed there, and the output is downloaded directly to your device. When you close the tab, nothing persists. We do not log file contents, file names, or any metadata about what you processed.
There is no server-side limit because nothing is uploaded. The practical limit is your browser's available RAM — typically comfortable up to 200-300 MB per file in Chrome and Firefox. For very large PDFs, processing takes longer but still works.
