How we handle your data

How the processing works — and how to check it yourself.

Twelve tools send the file nowhere

Merging, compression, text recognition, scan enhancement and eight more operations run right inside your browser. The document is never uploaded to our server — there is nothing to delete there, because nothing ever arrived.

It takes ten seconds to verify

Open the developer tools (F12), go to the Network tab and process a file — no request will carry your document. Or simpler still: turn off the internet after the page has loaded. The in-browser tools keep working.

What stayed on the server

Converting Word, Excel and PowerPoint and transcribing audio need server-side engines — they cannot run in a browser. That is why we do not offer them publicly: clients get those tools separately.

Free online PDF tools — compress, convert, merge

Twelve tools for working with documents, and every one of them runs right inside your browser: the file is never uploaded, and you can see that on the Network tab.

Frequently asked questions

Answers to the key questions about security, how the tools work and their limits.

Is it safe to process documents here?
All twelve tools run entirely inside your browser: the file is read from your disk, processed on your device and saved back. It is never sent to our server, so questions of storage and deletion simply do not arise. It takes ten seconds to check — open the Network tab in your developer tools.
Can I process documents with personal data — passports, contracts, medical records?
Yes, and this is exactly the case the whole thing was built for. The document never leaves your device: we do not receive it, do not see it and do not store it.
Do I need to register or install any software?
Nothing to install — everything opens in your browser. All twelve tools work without registration, an account or a password: choose a file and get the result.
Are files sent to OpenAI, Google or other external services?
No. All twelve tools run right inside your browser and send the file nowhere — neither to us nor to anyone else. No external clouds or APIs are involved at any point.
Are there any file size limits?
PDF tools accept files up to 200 MB. Audio and video transcription supports files up to 30 min · 500 MB. There is no limit on the number of operations.
How much do the tools cost?
Every tool is completely free. No hidden fees, no subscriptions and no limits. We built them as a complement to our core consulting business — for the convenience of our clients and everyone who works with documents.
Do the tools work on a phone or tablet?
Yes, everything opens in a mobile browser with no apps to install. Bear in mind that the tools compute on your own device, so large files take longer on a phone and very large ones may not fit into the tab's memory. For documents over 50 MB a computer is safer.
Can I compress a PDF to a specific size, say 1 MB?
The achievable size depends on the original content of the file. The compression tool lets you choose a quality level: screen (72 dpi), e-book (150 dpi) or print (300 dpi). The lower the dpi, the smaller the resulting file.
Are scanned PDFs supported when converting to Word?
For scanned PDFs we recommend running the OCR tool first — it recognizes the text and adds a text layer. After that, conversion to Word will be far more accurate.
