What PDFViz is
PDFViz is a set of free PDF tools that run in a browser tab, processing files there rather than uploading or storing them. The tools cover merging, splitting, compressing, converting, reordering, unlocking, password protecting, signing, filling forms, comparing, and repairing PDFs. Before offering a download, a tool reopens its output and checks it against the original; PDFViz says it withholds results that do not match. The Free plan costs nothing and requires no account. It has no watermark, site-set file-size cap, or daily cap, though large files may be constrained by the memory available to the browser tab and device. PDFViz says the tools can continue working after the page loads even when the network is disconnected. Its privacy page says it runs no usage-data scripts and sets no tracking cookies. Cloudflare sees standard request information while serving pages, but requests do not carry document content. The tools use Mozilla’s pdf.js to read and check PDFs and pdf-lib to write them. A current limitation is that PDFViz cannot read text from photographed scans because the required text-recognition engine is too large for a browser tab.
Who it suits
PDFViz suits people who want browser-based PDF tools without uploading documents or creating an account. It may not suit users who need text extraction from photographed scans or who work with files that exceed their browser or device memory.
