Why we built this
Most free PDF tools online ask you to upload your file to their servers first — which means your documents, invoices, IDs, or contracts pass through someone else's infrastructure before you get them back. PdfKaro does the opposite: every tool runs entirely inside your own browser, using your device's own processing power, so your files never leave your computer or phone.
What PdfKaro does
- Merge PDF — combine multiple PDF files into one, in the order you choose.
- Split PDF — extract specific pages from a PDF into a new file.
- Image → PDF — turn JPG or PNG photos into a single PDF document.
How it stays free
There's no account system, no storage costs from holding your files, and no server-side processing to pay for — so there's nothing to charge for. PdfKaro is maintained as a straightforward utility, not a subscription product.
