FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Laravel DWG Converter
繁體中文
Laravel DWG Converter lets Laravel applications extract embedded thumbnails from DWG files and convert DWG files to DXF, structural JSON, PNG, JPEG, or WebP.
Features
- Extract embedded DWG thumbnails.
- Convert DWG files to ASCII DXF.
- Export DWG files as structural JSON.
- Create PNG, JPEG, or WebP previews.
- Accept uploaded files, local paths, or DWG bytes.
- Store or stream results with Laravel Storage.
Requirements
| Requirement | Supported |
|---|---|
| PHP | 8.3 or later |
| Laravel | 12 or 13 |
| CI-tested combinations | PHP 8.3–8.5 with Laravel 12–13, including the PHP 8.3 / Laravel 12 lowest boundary |
External commands are feature-specific. You do not need LibreOffice or ImageMagick when you only extract thumbnails, create DXF, or export JSON.
External commands by operation
| Operation | Required commands |
|---|---|
Dwg::thumbnail(...)->extract() |
LibreDWG dwgbmp |
Dwg::toDxf(...)->convert() |
LibreDWG dwg2dxf |
Dwg::toJson(...)->convert() |
LibreDWG dwgread with JSON output support |
Dwg::toImage(...)->convert() |
LibreDWG dwg2dxf, LibreOffice 7.4+ soffice, ImageMagick 7 magick |
The package does not download or bundle these tools. For LibreDWG installation, see the official LibreDWG repository. The external tools guide covers LibreOffice and ImageMagick installation on Ubuntu/Debian, RHEL/Fedora, and Windows.
Installation
Install the package with Composer:
If a required command is not on PATH, publish the configuration and provide its absolute path:
Quick start
This example extracts the DWG's embedded preview and streams it to Laravel's default disk. The source is
an UploadedFile from a validated request.
A DWG may not contain an embedded thumbnail. Use image conversion when you need a rendered preview:
Inputs and outputs
Every operation accepts a valid UploadedFile, a local absolute path, or bytes explicitly wrapped with
DwgBinary::from($bytes). A plain string is always treated as a path.
Each successful operation returns a one-time DwgOutput:
extension()andmimeType()inspect trusted output metadata without consuming it.storeAs()streams the artifact to Laravel Storage and cleans up temporary resources.output()returns all bytes as a string and should only be used for outputs that safely fit in PHP memory.
Errors and operational limits
Failures use LibreDwgUnavailable, InvalidDwg, or DwgOperationFailed. Each exception provides a stable
reason() and sanitized scalar context().
The default limits are 200 MiB input, 512 MiB general output, and 64 MiB JSON output. Set a byte limit to
null, zero, or a negative integer to disable it. Keep positive limits and run untrusted DWG conversions in
a resource-limited worker or container.
Successful conversion means the configured tools completed the requested operation and the artifact passed the package's format checks. It is not a DWG safety certification, a full conformance check, or an AutoCAD visual-fidelity guarantee.
