Yes, all 25+ tools are 100% free. No account required, no subscription, no watermarks on output, no premium wall. Free forever. The service is supported by optional advertisements.
There is no hard file size limit. Very large PDFs (100MB+) may take longer depending on your device speed. The practical limit is your browser's available memory. Most PDFs are well under 50MB and process instantly.
Never. All PDF processing happens in your browser using pdf-lib, PDF.js, and jsPDF. Your files are never transmitted over the internet or stored anywhere. We have zero access to your files.
Yes, completely safe. Since all processing happens locally in your browser and files never leave your device, you can safely process confidential business documents, legal PDFs, or personal files.
The Edit PDF tool uses PDF.js to render your PDF pages as canvas elements in your browser. You can add text (click the T button then click where you want), draw freehand, add rectangles, and highlight content using the toolbar. When you click Save, all edits are rendered and embedded into the PDF as image layers.
The browser-based editor adds annotations on top of existing PDF content. True editing of existing PDF text requires server-side processing. To replace existing text, you can cover it with a white rectangle and add new text on top using the Edit PDF tool.
Use the Delete Pages tool. Upload your PDF and all pages render as readable thumbnails โ you can actually read the content before deciding which pages to delete. Click pages to select them (they turn red), then click Delete Selected Pages. Works 100% in your browser.
Use the Unlock PDF tool. You must know the current PDF password (this proves you have authorised access). Enter the password, upload the PDF, and click Unlock. The password is never sent to any server โ all decryption happens locally in your browser.
Yes. Select or drop as many PDFs as needed. Drag to reorder them in the list before merging. All pages combine in your chosen order.
Our compression tool uses pdf-lib to remove embedded metadata, thumbnails, and optimize PDF object streams. For text-heavy PDFs this can reduce size by 20-50%. For image-heavy PDFs, client-side compression is limited โ for maximum image compression, server-side tools give better results.
