A colleague sends a .vsdx file before a design review. Your computer does not have Visio, and you only need to read the pages, flag a misleading label, and share a PDF with the meeting group. That is a viewing and review task—not necessarily a reason to reconstruct the diagram.
Disclosure: this guide is written by the LayerBack team. It describes a review workflow rather than an independent compatibility benchmark.
Official sample diagram preview, not a screenshot of the viewer. Use the sample VSDX to practise page and label checks.
First identify what you received
If the attachment is a VSDX, start by opening that file. If it is a PNG or a PDF, changing the extension to .vsdx does not create editable Visio objects. Those inputs require a separate recovery workflow if object editing is needed.
Keep an untouched copy of the original. Record the document version or ask the sender which revision it represents. Viewing the right file is more useful than carefully reviewing an obsolete export.
Open the drawing in a browser viewer
LayerBack's VSDX viewer opens the file in the browser without uploading it as part of the viewer workflow. This differs from the image converter, which uploads an image for reconstruction.
Open the drawing and inspect every relevant page. Check page names, legends, labels, arrow direction, and clipping near page edges. Zooming the first page until it looks sharp is not a complete review of a multipage drawing.
If a font, icon, or specialized shape looks unusual, compare it with a reference PDF from the author. A browser rendering can be useful without being identical to the original application in every detail.
Review content with an explicit scope
Use this note template:
File and revision:
Pages reviewed:
Label or object needing correction:
Expected wording or destination:
Layout differences observed:
Reviewer:
For a quick wording correction, work on a copy and keep the requested change narrow. Do not make a structural change merely because editing controls are available. A diagram may carry process assumptions that only its owner can confirm.
Export a reading copy and reopen it
Use the viewer's export controls to create a PDF or image for recipients who do not need an editable source. Menu wording can change; inspect the available export options in the live interface.
Open the exported file and verify the pages you intended to share. Check legibility, boundaries, and branch labels. Do not assume that a successful export dialog means all pages or content are included as expected.
Preserve the original VSDX and any edited copy separately. A PDF is convenient for reading, but it should not become the only surviving version if the team will revise the diagram later.
If you only have a picture
Use an image-to-diagram workflow such as image to Visio when the diagram exists only as pixels. After reconstruction, verify individual shapes, text, and connectors before treating the new VSDX as a working source.
The viewer and converter have different purposes and pricing. The viewer is presented as a free tool; website conversion preview is also free, while a converted diagram's first download or edit currently uses 10 credits. See pricing for the conversion workflow.
For today's review, open the VSDX you already have, record the pages checked, and hand off a verified reading copy alongside the original drawing.
