ConvertKoala is a small, independent team that builds file tools for people who just want the job done. Merge a PDF, turn a few photos into a document, move on with your day.
Why we built it
Most online converters ask you to upload your files to a server you know nothing about, then cap how many you can convert before showing a paywall. We thought that was backwards. Your tax return, your contract or your kid’s school photos should not have to travel anywhere to be merged.
So every ConvertKoala tool does its work inside your browser, on your own device. There is no upload, which means there is nothing for us to store, lose or look at. It also means we have no per-file cost, so there is no reason to limit you.
What we promise
- Your files never leave your device.
- No file limits, no daily quotas, no paid tier.
- No account and no email required.
- One clear action per page, so nothing needs explaining.
How we keep the lights on
The site is free to use and will stay that way. To cover hosting and development we may show a small, clearly labelled advertisement on result pages. Ads never appear above the tool, and they never see your files.
