Every file tool you need, quietly in your browser.

Local PDF, image, video, audio, GST, and calculator tools process entirely in your browser. File bytes and calculator inputs are not uploaded. Some tools download a processing model or asset on first use, which never includes your file.

No. Every tool works without an account, and this build has no sign-in at all. You open a tool, add your file and download the result. There is nothing to register, no email to give and no profile that remembers what you worked on.

Local tools can work offline after their pages, processing code, and required assets have been cached. Load the tool and download any required OCR or video assets before disconnecting. Cloud AI and remote MCP features still need an internet connection.

Yes. The same app merges, splits, compresses, and signs PDFs, and converts images, video, and audio. Each tool page states accepted formats, where processing happens, and honest limitations.

Yes. GST, EMI, SIP, income-tax sketch, salary, and everyday math calculators run in your browser. Nothing is uploaded. Tax tools are illustrative sketches, not government filings.

You enter seller, buyer, and line items. Same-state supplies split GST into CGST and SGST; interstate supplies apply IGST. Totals round to paise. GSTIN checks are format-only. The tool does not register invoices with the government IRP.

No. Core local tools are free, add no product watermark, and download from your device. Future pricing would be disclosed on the pricing page before it changes in the product.

Open your browser developer tools, switch to the Network tab, then run any local tool on a file. You will see no request carrying your file. The /prove page does this check for you and shows what left your device while a conversion runs. Pages and code still load normally.

There is no fixed cap. The practical limit is your device memory, because the work happens locally. Current Chrome, Edge, Firefox and Safari all work. Safari on iPhone and iPad has stricter memory limits, so very large PDFs or videos may fail there and run better on a computer.

Automatic subtitle generation is unavailable. The two peer-to-peer tools, file sharing and the shared whiteboard, are same-device demos that connect browser tabs on one device, not people on other devices. Each tool page states what it does and does not do before you start.

You can choose from 40 interface languages. Ten of them have fully translated tool guides: English, Hindi, Spanish, Brazilian Portuguese, French, German, Italian, Arabic, Japanese and Indonesian. In other languages some guide text may appear in English until it is translated.
