How it works

Choose a file

Open a PDF or document on this page. SKY13.app does not send it to a server.

Download

The finished file is saved on your device.

The file stays with you

These tools run in the browser. Language and currency are chosen separately: a Hindi interface can still show prices in INR, USD, or EUR.

Common questions

Does SKY13.app upload my PDF?

No. Merge, split, compress, convert, sign, and the other tools on this site run in your browser. The file stays on your device.

Will this work on a phone?

Yes. The pages are built for narrow screens and for a desktop browser. Large files can take longer on a phone, so keep the tab open until the download appears.

Why are there prices in rupees, dollars, and euros?

SKY13.app picks a currency from your region, and you can change it without changing the language. Hindi and English are separate from INR, USD, and EUR.

Can I password-protect a PDF here?

Not in this version. A lock that only looks secure would be misleading, so password protect and unlock are not offered until a real worker can do them.
