What is PDF Smaller? PDF Smaller is a free toolkit of more than 25 PDF tools that run entirely in your web browser. Compress a file for email, merge several documents into one, split or reorder pages, convert to and from Word, Excel, PowerPoint and images, edit text, add a password, sign a contract, or run OCR on a scan — without installing software or creating an account. What makes it different is where the work happens. Most online PDF tools upload your file to a server, process it there, and send it back. PDF Smaller does everything locally on your own device, so your documents never leave your computer. Private files — contracts, IDs, medical records, tax forms — stay private by design, not just by policy. One toolkit, every common PDF job Optimize: compress , resize , and repair PDFs. Organize: merge , split , rotate , crop , and reorder pages . Convert: PDF to Word , Excel , images , and back again with JPG to PDF and Word to PDF . Secure & finalize: password-protect , unlock , watermark , sign , and OCR documents. Everything is free — no sign-up, no daily caps, no watermarks. To see how the browser-based approach works, read How It Works or browse the guides in our Learning Center . Frequently Asked Questions Everything you need to know about PDF Smaller Is PDF Smaller really free? Yes — every tool is free with no daily limits, no account, and no watermarks. The site is run by one independent developer and funded by unobtrusive display ads, which is what keeps the tools free for everyone. Do my files get uploaded to a server? No. Every tool runs entirely inside your browser, so your documents never leave your device. You can confirm it yourself: open your browser’s Network tab while you process a file and you’ll see no file data being sent anywhere. What can I do besides compress PDFs? PDF Smaller is a full toolkit. Beyond compression you can merge, split, rotate, crop and organize pages; convert to and from Word, Excel, PowerPoint and images; edit and annotate; add or remove passwords; sign documents; run OCR on scans; and convert to PDF/A for archiving. How much can I shrink a PDF, and will quality suffer? Compression typically reduces file size by 50–90%, depending on the content — image-heavy PDFs shrink the most. You stay in control: lighter settings preserve near-original quality, while maximum compression trades some fidelity for the smallest possible file. What is the maximum file size? You can process files up to 1GB each, and batch-compress up to 10 files at once — large enough for long scanned documents and image-heavy portfolios that most online tools reject. Does it work on my phone? Yes. Because everything runs in the browser, PDF Smaller works on phones, tablets, and computers across modern browsers — there is nothing to install and no app to download.
