Frequently asked questions
Is LumosPDF's PDF editor really free?
Yes. Editing text, images, and pages is completely free with no sign-in, no watermark, and no page limits.
Do my files get uploaded to a server?
No. LumosPDF works entirely in your browser. Your file is read from your device and never uploaded anywhere, so it stays completely private.
Can I edit the existing text in a PDF?
Yes. Unlike tools that only let you drop a text box on top, LumosPDF lets you click existing text and edit it in place while keeping the original font and layout.
Will editing change my fonts or break the layout?
LumosPDF reuses the document's embedded fonts and re-flows text within each block, so your edits blend in with the surrounding content.
Which browsers are supported?
Any modern browser — Chrome, Edge, Firefox, or Safari — on desktop or laptop. No installation or extension is required.
