SKY13.app is built for the ordinary PDF jobs people otherwise hand to a big converter site: merging a packet, splitting a scan, shrinking a photo PDF, signing a form, numbering pages, and moving text into Word or a sheet. The work runs in the browser. The product plan behind it keeps business rules out of the page, keeps secrets off the page, and refuses to treat a browser message as proof of payment.
The tool list follows the jobs people expect from products such as Smallpdf and Sejda: merge, split, compress, convert, organize, crop, watermark, sign, redact, OCR, and n-up. Where a browser cannot do the job truthfully, SKY13.app leaves it out. Password locks, PowerPoint conversion, and a designed Word layout are in that group. A file that only looks protected is worse than a missing button.
You can use the interface in English or Hindi. Prices can show in Indian rupees, US dollars, or euros. Those choices are remembered on your device and they do not depend on each other. The free tools are usable now. A future Pro plan is priced on the pricing page and cannot be activated from this website yet.
