vScan
Paper into a PDF, without re-encoding a single page.
The problem
The software that came with the scanner is usually the worst program on the machine. It takes half a minute to open, it wants an account, it saves everything as scan001.pdf in a folder nobody chose, and finding the setting for greyscale means three dialogs.
And most of them quietly compress every page twice — once when the scanner produces it, again when it goes into the PDF. A page of text ends up softer than it was and larger than it needs to be, and nobody is told.
What it does
1Nothing is re-encoded
The bytes the scanner produced go into the PDF exactly as they came — a JPEG page whole, a PNG page as its own compressed data. A page is never compressed twice, so nothing is lost putting it in and nothing is spent doing it.
2You see it before it is saved
Pages appear as thumbnails. Untick any that came out badly, give it a name, then press Save. Until then no file exists at all.
3It never writes over anything
If the name is taken it adds a number. Yesterday's invoice is not replaced because today's pattern produced the same name.
4Names you can find again
Scan 2026-01-15 09-30-45, or your own pattern with the date, the page count or the resolution in it. Shown before the scan rather than discovered afterwards.
5The settings are in front of you
Colour, detail, glass or feeder — one row across the top, always visible. Nobody should have to open a dialog to find out whether it is set to colour.
6Feeders and both sides
A document feeder runs until the paper stops, and pages appear as they come. Both sides at once if the scanner can do it — and the option only appears if it can.
7A4 in, A4 out
A page scanned at 300 dpi comes out the size it should be on paper. Scanner software gets this wrong often enough that a scan of a letter opens as a poster.
8A note of every scan
What it was called, how many pages, and whether the file is still where it was put.
Why it is worth it
Windows Image Acquisition — the same interface Windows' own scanning uses. No driver to install, no service, nothing running in the background.
vScan says which folder they are in. A scanner that throws away forty sheets because a disk was full is one somebody has to feed forty sheets into again.
vScan produces PDFs and vPDF is what opens them. A scanner that made itself the handler for .pdf would be taking a file type from its own sibling.
No account, no cloud, no "scan to email" that routes through somebody else. The file goes in the folder you chose.
How you use it
Or a stack in the feeder.
Colour or greyscale, how much detail, glass or feeder. It stays as you left it.
The pages appear. Click one to see it full size.
Or take the suggested name, which has the date in it.
What it needs
| Windows | 10 or 11, 64-bit |
|---|---|
| Scanner | Any with a WIA driver — nearly all made since about 2005 |
| Installs to | Your user profile — no administrator prompt |
| Network | None — vScan never connects to anything |
| Goes with | vPDF, for reading and marking up what comes out |
What it will not do, said plainly
Scanners with only a TWAIN driver do not appear at all. Some older machines and some professional film scanners are TWAIN-only, and that is the one real thing the specialist scanning tools do that vScan does not. When it finds nothing it says this, rather than showing an empty list and leaving you to check the cable.
It does not make the text searchable. That needs optical character recognition, which is a large piece of software and not one to pretend about — a vScan PDF is pictures of pages. Anything that adds a text layer can do so afterwards.
It does not straighten, crop or clean up a page. It gives you what the scanner gave it. Adjusting a scan afterwards is a job for an image editor, and doing it badly inside a scanner is how a document ends up with its edges cut off.
