Real reviews from people who edit PDFs with lumr every day.
Marco De Luca
Creative Director
“Honestly? I cancelled my other subscriptions. Editing a PDF here is just that smooth, and the UI doesn't make my eyes bleed, which is a huge plus.”
Emily Watson
Small Business Owner
“Running a small bakery means I wear a hundred hats. I use lumr to sign contracts, merge invoices, and fix typos in menus. Best tool I added this year.”
David K.
Senior Software Engineer
“I paste in scanned specs, OCR them, and convert to Word in seconds. It handles messy layouts surprisingly well. Way better than juggling three different apps.”
Sofia Romero
Marketing Manager
“Compressing decks before a client send used to be a chore. Now it is one drag, one drop, done. The quality stays crisp every time.”
James O'Brien
Freelance Designer
“The e-signature flow is ridiculously fast. I sent a proposal, the client signed on their phone, and it was back in my inbox before my coffee was cold.”
Aisha Khan
Operations Lead
“We process dozens of forms a week. Filling and exporting them in lumr cut our turnaround time roughly in half. The team actually enjoys it now.”
Lukas Becker
Graduate Student
“Summarizing 60-page research papers before a seminar is a lifesaver. I get the gist in a minute and dive into the details that matter.”
Priya Nair
Product Manager
“Talking to my PDFs feels like cheating. I ask where a clause is and it points me straight to it. No more endless scrolling through contracts.”
