The Smartest PDF
Toolkit on the Internet
38+ free PDF tools that run entirely in your browser.
Merge, split, compress, convert — your files never leave your device.
PDFDroid is a free online PDF editor and converter that runs entirely inside your web browser. Unlike most PDF websites, your files are never uploaded to a server — every operation happens locally on your device, so your documents stay 100% private. There is no sign-up, no watermark, and no daily limit.
With 38+ tools in one place, you can merge PDF files into a single document, split a PDF by page ranges, and compress PDF files to reduce their size without losing readability. Need a different format? Convert PDF to Word, PDF to JPG, PDF to PNG, PDF to Excel, PDF to PowerPoint, PDF to Text, PDF to HTML and PDF to SVG — or go the other way with JPG to PDF, Word to PDF, CSV to PDF and HTML to PDF.
PDFDroid also handles everyday document jobs: rotate, crop and resize pages, extract, delete or reorder pages, add a watermark, stamp, page numbers or QR code, and e-sign your PDF with a hand-drawn signature. For security, you can password protect (encrypt) a PDF or unlock one you own, and for optimisation you can repair, flatten, grayscale, extract images from and optimise any PDF.
Because everything is browser-based, PDFDroid works on Windows, macOS, Linux, Android and iOS — on phones, tablets, laptops and desktops alike. It is a fast, secure and genuinely free alternative to tools like iLovePDF, Smallpdf, PDF2Go, Sejda and Adobe Acrobat online. Browse all 38+ PDF tools →
Is PDFDroid completely free?
Yes. All 38+ PDF tools on PDFDroid are free — forever. No subscription, no watermark, no account required.
Are my PDF files private and secure?
Yes. All processing happens entirely in your browser using JavaScript. Your files are never uploaded to any server — they stay 100% on your device.
Does PDFDroid work on mobile phones?
Absolutely. PDFDroid is fully responsive and works perfectly on all devices — phones, tablets, laptops, and desktops.
What is the maximum PDF file size I can process?
Since processing is done in your browser, it depends on your device's RAM. Most modern devices handle files up to 200MB easily. For very large files, we recommend using a device with more RAM.
Can I use PDFDroid offline?
After the initial page load, most tools work offline since no server requests are made during file processing.
Is PDFDroid better than iLovePDF or Smallpdf?
Unlike iLovePDF and Smallpdf which upload your files to their servers, PDFDroid processes everything locally in your browser — making it significantly more private and secure, with no file size restrictions or daily limits.
