Free Online PDF Tools

Online PDF tools are browser-based utilities that let you manipulate PDF files directly in your web browser without installing any software. They are ideal for quick tasks like merging multiple PDFs into one document, splitting a large PDF into smaller files, compressing PDFs to reduce file size for email, converting between PDF and image formats, adding password protection, or signing documents electronically. Unlike desktop software that requires installation and often costs money, online PDF tools work on any device — Windows, Mac, Linux, or mobile — and require zero setup. Our tools process everything locally in your browser using JavaScript, meaning your files are never uploaded to any server, ensuring maximum privacy and speed.

To merge multiple PDF files into a single document, open our PDF Merge tool, drag and drop your PDF files into the upload area (or click to browse and select files). You can arrange them in your desired order by dragging the thumbnails. Once you are happy with the order, click the Merge button. The combined PDF will be generated instantly in your browser and ready for download. You can merge 2 or more PDFs at once, and there is no file size limit. The entire process happens locally on your device — your files never leave your computer, ensuring complete privacy.

Yes, our PDF Compress tool offers multiple compression levels so you can balance file size and quality. The default balanced mode typically reduces file size by 40-70% while maintaining excellent visual quality for most documents. For documents with many photos, you can choose a higher compression level to achieve even smaller files, though images may show slight quality reduction. For documents that need to look pixel-perfect (like design portfolios or print-ready files), use the minimum compression setting. All compression is performed entirely in your browser using advanced algorithms — no server upload required, and no watermark is added to the output.

Our PDF to Image converter supports exporting PDF pages as PNG and JPEG formats. PNG is recommended for documents with text, diagrams, or sharp edges because it provides lossless quality. JPEG is ideal for PDFs containing photographs where smaller file size is preferred. You can convert all pages at once or select specific page ranges, and the output resolution is customizable. For the reverse direction, our Images to PDF tool accepts JPG, PNG, WebP, BMP, and GIF images. You can adjust page size (A4, Letter, or custom), set margins, and reorder images before conversion. Both tools run entirely in your browser with no file uploads.

Our E-Sign tool allows you to add electronic signatures to any PDF document in three easy steps. First, create your signature by drawing it with your mouse or finger on a touchscreen, typing your name and choosing a signature style, or uploading an image of your handwritten signature. Second, open your PDF in the tool and navigate to the page where you want to sign. Third, click to place the signature, resize and position it precisely, and save the signed document. The signed PDF can be downloaded immediately. Your signature data and documents remain entirely on your device — nothing is transmitted to any server, ensuring your signature stays private and secure.
