Drag black boxes over names, account numbers, signatures or anything else, on any page, then export a PDF where the covered content is truly gone. Your PDF never leaves your device.
Drawing a black box in most PDF apps only covers text, which can still be copied out. Here every page is flattened to an image with the boxes burned in.
A PDF page is layers of text, images and drawings. A black rectangle added in a typical editor is just one more layer on top, and the text underneath can still be selected, searched and copied.
NoUpload renders each page to an image, paints your boxes into the pixels, and builds a new PDF from those images. The output has no text layer, metadata, comments or earlier versions, so there is nothing underneath to recover.
Flattened pages are not text-searchable, and the file can be larger than the original. For documents you only need to share or print, that is usually fine. Pages are rendered at roughly 200 dpi, sharp for reading and printing.
On any page: names, numbers, signatures, photos.
Pages become images in this tab, so no text survives underneath.
The output is inspected again for metadata and hidden content.
For client work, ID scans, medical documents, unreleased product shots, or anything else you do not want sitting in a stranger's storage, the safer upload is the one that never happens.
File processing runs in your browser. Google Analytics records page views and anonymous tool-usage events, but NoUpload does not send filenames, metadata values, file sizes, image blobs, or other file details as analytics data.
Anyone can claim files stay on your device. Here is how to confirm it yourself in under a minute, with tools already in your browser.
Or go further: load the page, switch off Wi-Fi, and use the tool. Processing still works, because it never needed a server.
What NoUpload does with files: image inspection, cleaning, resizing, and compression happen in your browser. Your files are not uploaded to NoUpload for processing.
What this site collects: standard page-view analytics plus anonymous usage events (a tool was opened, a file was added, processing started, an export completed) that record only the tool and page name. Google Analytics may record approximate location, device/browser type, and pages visited. NoUpload does not send filenames, image data, metadata values, file sizes, dimensions, or file counts.
Terms: NoUpload is provided free, as-is, with no warranty of any kind. Use it at your own risk.
