Is this PDF tool completely free?

Yes. All PDF tools on this page — merge, split, compress, and watermark — are 100% free with no usage limits, no account required, and no watermarks added to your output files.

Are my PDF files safe? Are they uploaded to a server?

Your files never leave your device. All PDF processing happens entirely inside your web browser using JavaScript and WebAssembly. No file is uploaded to any server, making it completely private and secure.

How much can I compress a PDF file?

Using the Image Re-render compression mode, you can typically reduce PDF file size by 60–85%. The Fast mode removes metadata and redundant objects, usually achieving 5–15% reduction. Image-heavy and scanned PDFs benefit the most from the Image Re-render mode.

How do I add a watermark to a PDF?

Go to the Watermark tab, upload your PDF, type your watermark text (or upload a logo image), set the opacity and angle, then click 'Apply Watermark'. A live preview shows on the right side as you adjust settings. The watermarked PDF is ready to download instantly.

Can I split a PDF into individual pages?

Yes. In the Split tab, upload your PDF then choose 'All Pages' to extract every page as a separate PDF (downloaded as a ZIP), 'Pick Pages' to visually select specific pages, or 'Page Range' to enter a range like 1,3,5-8.

How many PDF files can I merge at once?

There is no hard limit on the number of files you can merge. You can combine as many PDF files as your browser's available memory allows. Drag to reorder them before merging.

Will PDF compression make text unsearchable?

The 'Fast' compression mode preserves all text and searchability. The 'Image Re-render' mode converts each page to a compressed JPEG image, which gives the highest size reduction but makes text non-searchable. Choose based on your needs.

Can I add an image or logo as a watermark on a PDF?

Yes. In the Watermark tab, click 'Image' to switch from text to image mode. Upload your PNG or JPG logo, adjust the scale (5–100%), opacity, and rotation angle. The watermark is applied to every page of the PDF.
