Everything Mermaid2Visio has become—kept in one place.
This page tracks meaningful customer-facing capabilities and changes from the first working lab through today’s five available conversion workflows. It will move forward with every cumulative release.
Five workflows. Editable, reviewable outcomes.
Mermaid to editable Visio is available to Basic and Pro. Visio, SVG, Draw.io, and supported embedded-source PNG workflows are included with Pro. Ordinary PNG screenshots remain unsupported while external vision processing is disabled.
Product history
Customer-facing milestones are grouped into readable releases; internal-only maintenance noise is intentionally excluded.
Honest cancellation and payment-decline returns
Returning from Stripe now clearly confirms when checkout was cancelled or a payment was not accepted, without exposing provider error details.
- Confirms that nothing was charged and the selected plan is not active.
- Keeps secure checkout resumable while preventing duplicate paid journeys or subscriptions.
- Provides clear resume and pricing actions in English and French.
Guest-first conversion paths and discoverable examples
Every converter now leads prospects directly to secure Pro checkout, unfinished checkout can be resumed on-site, and dedicated demonstrations and examples make each workflow easier to evaluate.
- Removed remaining sign-in-first upgrade paths and clarified guest-first compatibility copy.
- Added persistent checkout continuation and a measurable recovery-consent wording experiment.
- Published five lightweight converter demonstrations and downloadable source/output examples.
- Added stable English and French URLs, hreflang metadata, improved sitemap dates, and new high-intent converter landing pages.
- Standardized structured conversion failure codes for safer funnel diagnosis.
Five professionally qualified conversion workflows
Draw.io recovery preserves more source hierarchy and visual intent, SVG produces two editable outputs, and supported Draw.io PNG exports can now be recovered privately into Mermaid and Visio.
- Improved containers, nested scopes, titles, annotations, neutral styling, dashed connections, and multi-page handling in Draw.io to Mermaid.
- Added deterministic SVG to reviewable Mermaid alongside the geometry-preserving editable Visio output.
- Added private PNG recovery for Draw.io exports that include embedded diagram data, with no external AI processing.
- Added immediate file-picker and conversion feedback, including keyboard-accessible file selection.
- Added broader visual and semantic regression corpora across Mermaid, Visio, SVG, Draw.io, and supported PNG workflows.
- Simplified converter navigation and grouped the product footer around conversion, trust, product, and support tasks.
- Ordinary PNG screenshots remain unsupported until a privacy-reviewed provider and end-to-end visual-quality gate are approved.
Mermaid-first, review-first workbenches
Mermaid → Visio is once again the unmistakable flagship while every additional converter follows one coherent review-first system.
- Restored the Mermaid source and live diagram workbench immediately after the primary homepage message.
- Moved Visio, SVG, Draw.io, and PNG into a compact additional-converters selector without removing their dedicated pages.
- Standardized Source, Visual review, and Output steps across secondary converters.
- Added original-image comparison for PNG recovery and a safe original-source preview for SVG conversion.
Clearer file-selection workflow
Every converter now makes the first action and the next step visually unmistakable.
- Added prominent Choose file controls for Mermaid, Visio, SVG, Draw.io, and PNG inputs.
- Inactive conversion buttons now explain that a source file must be selected first.
- Unified responsive upload styling across the complete converter suite.
The five-converter suite
Mermaid2Visio expanded from its original forward converter into a governed, commercially validated diagram-conversion suite.
- Visio VSDX to reviewable Mermaid passed its commercial semantic-quality gate.

- Draw.io gained multi-page Mermaid and editable VSDX conversion.

Measurable checkout recovery
The purchase path became easier to resume and diagnose without weakening customer consent or payment safety.
- Added checkout recovery tracking and customer-safe retry paths.

SVG to editable Visio
Supported SVG diagrams could now become editable Visio content instead of a flat embedded image.

Visio to Mermaid Pro beta
