What it does

Four jobs that eat your Thursday afternoon,
handled.

/ 01

Optimize

“Outlook bounced it. Again.”

A 96 MB workbook or a 180 MB drawing set reduced to something you can actually attach — every formula, pivot, macro, hyperlink and form field still working. Name a target size and it works back to fit.

85%typical reduction
/ 02

Submission

“The portal caps at 25 MB and it closes at five.”

Give it the limit and hand it the whole package — pricing schedule, method statement, drawings, technical response. It optimises the set together and produces an upload-ready folder that fits.

380→24 MBa real tender pack
/ 03

Convert

“They sent a scan and want it in Word by lunchtime.”

PDF to Word, Excel, PowerPoint or images, and Office back to PDF. Scanned pages are recognised on the way through, so what lands is genuinely editable rather than a picture of a document.

6conversion directions
/ 04

Edit PDFs

“It needs filling, signing, and one clause taken out.”

Text, ticks, highlights, stamps, shapes and saved signatures — placed by clicking, snapped to detected fields. Plus proper redaction: the characters leave the file, and the output is reopened to prove it.

Sound familiar?

You’ve had this afternoon before.

Tender day

“Submission closes at 5pm. The package is 380 MB. The portal takes 25.”

Four files, four formats, one hard ceiling — and the last person who compressed the workbook broke a pivot table nobody noticed until after award.

→Submission: give it the limit, hand it the folder, get an upload-ready package with the spreadsheet logic intact.

The bounced email

“Your message couldn’t be delivered. Attachment exceeds 20 MB.”

So you upload to Drive instead, send a link, and the client emails back asking why they need an account to read their own contract.

→Shrink it to attachable and just send the file. No link, no login, no third party holding a copy.

The scan

“Can you get this into Word? It’s only 40 pages.”

It’s a scan of a scan with no text layer. Retyping is two hours you don’t have, and the free online converter wants you to upload a signed client agreement.

→OCR and convert in one pass, locally. Editable Word with the layout intact and nothing uploaded.

The redaction

“Take the account number out before this goes to the other side.”

You draw a black box in Preview. The number is still in the file — select the page, paste it anywhere, and out it comes. That’s how redaction failures make the news.

→Redact removes the characters, then reopens the saved file and searches it to confirm nothing survived.

No signal

“We’re on a satellite link and the upload’s been spinning for forty minutes.”

Cloud tools assume bandwidth. A rig, a remote plant, a basement records room and a plane all assume otherwise.

→Everything runs on the laptop’s own processor. No connection makes no difference.

The security questionnaire

“Which third parties process our documents, and where are they stored?”

Every cloud tool you use becomes a line on that form, a vendor to assess, and a jurisdiction to explain.

→None and nowhere. There’s no processor to name because the file never leaves the machine.

Next How the security holds up Offline by architecture, verified redaction, and a statement written for vendor assessments.
