Read a PDF’s hidden properties: who made it, with what software, when, who commented, and whether earlier versions are still inside. Your PDF never leaves your device.
Check a document before you send it, or check one you received. Nothing is uploaded to read it.
Author and comment authors are the most sensitive: they name people. Created with and PDF producer reveal the software, and sometimes the scanner or printer, used. Dates show when the document was really written, regardless of the date typed on the page.
Earlier saved versions means the file contains incremental updates. Content that was deleted or changed may still be present in the file even though it no longer shows on screen.
Author, software, dates, XMP, comments, attachments and saved versions are listed.
A new PDF is made in this tab, leaving hidden data and history behind.
The downloaded file is inspected again so you can see nothing is left.
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.
