Keep files under your control.
Run conversion on your computer or your own server. There is no need to send source documents to an external conversion service, including when creating previews of confidential material.
Local conversion. Open possibilities.

See the content. Skip the hunt for the original app.
Turn PDFs, Office documents, diagrams and CAD drawings into one SVG image per page. document-svg is an open-source conversion engine that gives very different files a common way to be seen.

More of the content.
A drawing arrives, but you do not have the CAD app. Your product needs document previews, but every file type needs a different viewer. Convert the file into SVG pages first, and the person viewing it only needs a browser.
document-svg is an engine for your tools and workflows: run it from the command line or build it into your own application.
02
Make viewing the easy part.
The output is an ordinary SVG image. Put it on a web page like any other image. Reviewers do not need Office or CAD software, and vector lines and shapes stay sharp as they zoom.
03
Know what needs a second look.
Substituted fonts, omitted elements and approximations are recorded in the conversion report. Check the result and its warnings before deciding whether a page is ready to share.
01 / The real output
Different files.
A common view.
Slides, spreadsheets, diagrams and models. Switch between formats to inspect SVGs generated from actual project samples.

Want to try it without installing?The official browser demo converts PDF, Word, Excel and PowerPoint inside your browser. Your file does not need to be uploaded.
02 / Put it to work
Start with the task.
Find your workflow.
A useful tool should fit a real problem. Here is what changes, and how to start.
01Choose a file→↳Convert locally→03View in a browser
Spend less time asking, “Can you open this?”
The everyday problem
The presentation is in PowerPoint, the estimate in Excel and the drawing in DXF. Not everyone who needs to review them has the software that created them.
What changes
Convert each document into SVG pages and place them in your internal portal or sharing interface. Reviewers open a browser instead of finding a different application for every document.
Your first step
Use the CLI to convert one file. Check the page images and the conversion report, then share them through a location approved by your organisation.
Start with the CLI03 / Under the hood
One SVG per page.
A report alongside it.
The inputs vary; the output structure stays familiar. Display the page images, then check the report for the parts that need review.
Provide a file
A PDF page, a PowerPoint slide or a printed Excel page becomes a page of output. Each format keeps its own natural page boundaries.
Convert in your environment
Run the CLI or call an API. A separate WebAssembly build also supports PDF and Office conversion inside a browser.
View the pages. Read the warnings.
Open the SVG in a browser. conversion.json records the page count and warnings, including skipped or approximated content.

04 / Find your format
From everyday files
to technical drawings.
Support does not mean the same fidelity for every file type. Find a format below, then use the full matrix to check exactly what is rendered.
6 categories shown
CategoryExamples & extensionsWhat to expect
PDF / Office
.pdf.docx.xlsx.pptx.odt.ods.odpRender document pages and worksheet print pages. Layout is not guaranteed to match Office exactly.
Diagrams
.drawio.vsdx.mmd.puml.d2.dotTurn flowcharts and architecture diagrams into SVG, including diagrams maintained with your source code.
CAD / CAM
.dxf.gbr.gcode.pltPreview drawings, boards and machining paths. Some formats produce a summary rather than a complete drawing.
3D / BIM
.stl.obj.step.iges.gltf.ifcRender supported elements of models and building data for inspection. Coverage varies by format.
Data / Math
.csv.json.yaml.tex.geojsonCreate SVG tables, charts, formulas and maps for web pages or reports.
Images
.png.jpg.tiff.webp.svg.dcmUse a common output for images too. Raster image detail remains limited by the source resolution.

Your environment.
Your next step.
Start with one sample. Check the pages and the warnings, then connect conversion to your existing work or application.
Get started
Choose the CLI for a quick local conversion, or a package for the language your application already uses.
Download the CLI03
Check the output
Open the SVG in a browser and read warnings in conversion.json. Compare pages with the original before sharing when warnings are present.
Requires Rust for this install command. To use the CLI without Rust, download a build for your OS from Releases and add docsvg to your PATH.
01 / Install
cargo install document-svg --locked02 / Convert a file
docsvg slides.pptx --output out/slides
# Open an SVG in a browser and check the report
# out/slides/page-0001.svg
# out/slides/conversion.jsonUse a new or empty output directory.
Full guideWill the output look exactly like the original?
Exact reproduction is not guaranteed. Unsupported elements and available fonts can change the layout. Check the generated pages and warnings. For PDFs, embedded text can optionally be converted to outlines, but outlined text can no longer be edited or searched as text.
Can people select or search the text in an SVG?
SVG can retain text information. However, when a page is displayed as an image, as on this site, its text cannot be selected or searched. Plan text extraction and search separately from image display.
Does converting SVG back to Office restore an editable document?
Reverse conversion packages the visual appearance into a PowerPoint, Word or Excel file. It does not rebuild the original paragraphs, cells, formulas or charts. draw.io is an exception: when source data was embedded during conversion, its editable diagram can be restored.
Are documents sent to an external server?
The conversion core does not send input documents to an external conversion service. Run it on your machine or a server you control. You manage access when publishing the generated SVGs. The “Try your own file” link opens the official demo, which processes supported files inside the browser.
What if my service accepts files from other people?
The engine does not execute macros or scripts and has input, expansion and page limits. These are protections, not a guarantee of safety. Convert untrusted files in an isolated process with time and memory limits. Display SVGs as images rather than inserting unchecked SVG source into HTML.
Can I use it in a commercial product?
Choose either the MIT or Apache-2.0 licence. Keep the copyright and licence notices required by your chosen licence when redistributing it. The repository also includes notices for bundled dependencies.
