WikiPlus hosts the largest collection of private, browser-based PDF utilities online. Merge, split, rotate, watermark, number pages, extract text, compress for email, strip metadata, repair a corrupted file, convert PDF pages to images or combine images back into a PDF, and even render a web page as PDF. All seventeen tools use the pdf-lib and MuPDF open-source libraries entirely on the client side — no upload, no watermark on your output, no filesize gate, and no daily quota.

Every tool on this page runs entirely inside your browser. Nothing is uploaded to our servers, nothing is cached for later, and no account is required. Files are processed on your own device using WebAssembly modules and the open-source libraries that power each utility, which means confidential documents stay confidential — even if you disconnect from the internet after the page loads, most tools will still finish their job. Pick the utility you need below and start working straight away.

Frequently asked questions

Are my PDFs uploaded to your servers?
No. The pdf-lib and MuPDF libraries both run as WebAssembly inside your browser, and every byte stays on your device. You can verify by opening DevTools Network panel during processing — no outbound requests appear while the tools work.
Is there a page-count or filesize limit?
No fixed limit. Browsers comfortably handle 500-page PDFs; very large documents (1,000+ pages) may be slow but succeed. Memory, not file size, is the bottleneck — a 2,000-page text PDF works, while a 200-page 4K-image scan may not.
Can I merge password-protected PDFs?
Yes. The merge tool accepts encrypted PDFs but prompts for the owner password before processing. The output is a single unencrypted merged PDF — you can re-encrypt it afterwards with a separate password-protection tool if needed.
