VSD Viewer for Visio Drawings

Review by eFreeware

The most distinctive thing about VSD Viewer is what it does not try to be. It is not a diagram editor, a whiteboard or a collaboration tool. It is a viewer for Microsoft Visio drawings in VSD, VDX and VSDX formats, built by Nektony, and it exists so that a file someone sends you can be opened and read on an Android device rather than left waiting until you are back at a desk.

That narrowness is the point. If Visio files land in your inbox or on a shared drive and you need to look at them away from a computer, this is the sort of tool worth knowing about. If you are the person who creates those diagrams, the app is not built for that job and the developer does not present it as such.

It has been on Google Play a long time, and the numbers reflect a modest, specific audience: over 10,000 installs and a 3.9 average from 305 ratings.

Built for people who receive Visio files

The clearest fit is anyone who is on the receiving end of Visio output: an engineer checking a drawing a colleague sent before a meeting, a project coordinator confirming a process diagram matches what was discussed, a contractor reading a floor or network layout while standing on site. These are people who need to see the drawing, not change it.

A second group is students and technical readers working with diagrams that lean on formatting rather than plain shapes. The app handles lines, fills, colors, gradients, text formatting, subscript and superscript, and tabulated text of the sort used in the frames of technical diagrams. If a drawing's meaning lives partly in those details, a viewer that ignores them would be useless, and this one is aimed at preserving them.

The app also suits people who deal with layered drawings. Visio files often stack several layers in one document, and being able to hide or reveal them changes what you can read at a glance. That is a feature you notice only when you need it, and it is one of the more practical things here.

What you can open and how you move through it

Multipage documents are navigable, with scrolling and zooming, and page numbering is supported so you can tell where you are in a long file.

Rendering goes beyond simple shapes. Original dimension units are shown, which matters when a drawing's measurements are part of what you are reading.

There are also controls for what gets displayed. You can switch the visibility of document guides, view documents with hidden objects, and see objects that sit outside the page boundaries, which is where stray annotations and notes often end up. Text in drawings can be copied out, which suits anyone who needs a label, a part number or a caption elsewhere.

Layer control and shape data

Beyond the basics, the app gives you control over layers. You can preview hidden layers and switch layer visibility on and off, so a drawing built from several stacked layers can be read one level at a time instead of as a single flattened image. On a small screen that is often the difference between a legible diagram and a tangle of overlapping lines.

The app also previews object shape data. For anyone who works with diagrams where the metadata carries as much as the picture, that is a meaningful inclusion.

Two practical limits are worth setting expectations around. Large files with many images may take a while to open. And rendering of built-in metafiles requires an internet connection, because those metafiles are sent to a remote server to be rendered rather than handled on the device.

A one-time purchase, with no ads

VSD Viewer costs $9.99. It contains no ads and offers no in-app purchases, so the price you see is the whole arrangement: you pay once and the app does not ask again. For a tool with a single clear job, that is a straightforward model, and it means there is no advertising sitting between you and a drawing you are trying to read.

The decision rests on whether the format support matches the files you actually receive. Checking that your drawings are VSD, VDX or VSDX, and that they fall within the Visio 2000 to 2013 range the developer describes, is the sensible step before buying.

It is also worth remembering that metafile rendering depends on a connection to a remote server, so any part of a drawing that relies on that will not render without one. That is a condition of how the feature works rather than a flaw, but it belongs in your thinking about where and when the app is useful.

How it compares with the alternatives

The obvious alternative is a general-purpose file viewer or office suite that happens to open Visio formats. Those tools are typically broader, and breadth is exactly what makes them appealing if you deal with many file types. What they tend not to do is treat Visio specifics as first-class: layer visibility switching, shape data preview, guides, objects outside page boundaries and original dimension units are the kind of details a general viewer rarely bothers with.

A dedicated diagramming app is the other direction. Those are built for creating and editing, and they carry the weight of that purpose. If your need is to read a drawing someone else produced, paying for an editor's feature set is a poor match, and the file formats you receive may not be the ones such tools handle best.

The remaining option is simply to wait until you are at a computer. That costs nothing and works, which is why the case for this app depends on how often Visio files reach you while you are away from one. For occasional files, waiting is reasonable; for regular ones, a viewer that respects the format's structure is the better choice.

A practical viewer for a specific file type

VSD Viewer does one job and does it without advertising or extra purchases. It opens VSD, VDX and VSDX drawings, preserves the formatting that gives technical diagrams their meaning, and gives you layer controls and shape data that a general-purpose viewer would likely skip. The 3.9 average from 305 ratings suggests a settled, workmanlike reception rather than a runaway favorite.

I would recommend it to people who regularly receive Visio drawings and need to read them on a phone or tablet: engineers, coordinators, site staff, students working with technical diagrams. The $9.99 price is easy to justify if that describes your week; it is harder to justify if Visio files reach you a few times a year and a desk is usually nearby.

What I would keep in mind before buying is the format range the developer describes, since the app is built around Visio 2000 to 2013 VSD files together with VDX and VSDX, and the fact that metafile rendering needs an internet connection. Neither is a surprise given what the app is, but both shape whether it fits your files and your working conditions.
