Voluntary support
Buy the server a coffee
PapelPDF is free, with no accounts and no ads. If it saved you time, you can leave a one-off donation; if not, keep using it just the same.
Why we ask for donations
Most tools run inside your browser and cost nothing per use. The specialised conversions — Word, Excel, PowerPoint, EPUB, PDF/A — need a server running around the clock. That server is paid every month with or without donations: what arrives here decides how much room there is to keep it running and improve it.
Where the money goes
- The conversion VPSThe machine that runs LibreOffice and Ghostscript for the formats a browser cannot convert.
- Domain and certificatesThe yearly cost of keeping papelpdf.cardevs.com up and served over HTTPS.
- New toolsEvery added tool comes out of working hours; donations buy time to keep going.
Fair questions
- Does anything change if I do not donate?
- Nothing. There are no locked features, no limits and no paid tier. Donating unlocks nothing because nothing is locked.
- What data do you see?
- The payment happens entirely inside whichever platform you pick: no card number and no credentials pass through this site. It tells the recipient the name and email tied to the donation, and none of that is ever linked to your files.
- Is there a receipt or a tax break?
- The platform emails its own confirmation. This is not a registered non-profit, so the donation is not tax-deductible.
- Is this a subscription?
- No: it is a single payment you choose. Nothing is set up to recur next month.
How to donate
Pick whichever platform you prefer. The payment happens on their site, in another tab: you choose the amount and the currency.
The link opens in a new tab. Depending on your country, the platform may ask for an account or let you pay by card alone.
This page loads no third-party scripts: the buttons are plain links, so nothing here tracks you.
