PART OF THE VELORA TOOLKIT
Most free PDF tools work the same way: you upload your file to someone else's server, it gets processed, and you download the result. That's fine for a public flyer. It's a bad trade for a contract, a payslip, or a scanned ID.
VeloraPDF does the same jobs — merge, split, rotate, compress — but the file never leaves your browser tab. The PDF is read, edited, and rebuilt entirely on your device using open-source libraries that run in JavaScript, the same way a spreadsheet formula runs locally in your browser. Close the tab, and nothing of your file remains anywhere but your own downloads folder.
When you pick a file, it's read directly from your disk into the page's memory. The merge, rotate, or compress operation happens in that memory. The result is offered back to you as a download. At no point does the file's content get sent over the network to us or anyone else.
VeloraPDF is the second tool in the Velora toolkit, after VeloraGif, a browser-based GIF and image editor built on the same principle. Both exist because everyday file editing shouldn't require trusting a stranger's server with your documents.
