Free online SDA to PNG converter

Older StarOffice drawing files are not supported by many image viewers, websites, and publishing systems. Converting an SDA drawing to PNG makes its artwork usable as a standard image for sharing or inserting into documents.

What the SDA format is

SDA is the legacy StarDraw drawing format used by StarOffice, the office suite that preceded OpenOffice.org and LibreOffice. It stores drawing documents, including vector shapes and text, rather than a single fixed-resolution bitmap. You may encounter SDA files in archives created with older StarOffice versions.

What the PNG format is

PNG is a raster image format supported by browsers, image viewers, and common editing software. It preserves sharp edges without lossy compression and supports transparency. Unlike an SDA drawing, a PNG does not retain editable vector objects; its dimensions and resolution determine how much detail it shows when enlarged.

How to convert SDA to PNG

Online on 101convert.com

1. Upload the SDA file to the converter on this page. Multiple files can be added as a batch; each file is subject to the size limit shown on the page.
2. Before converting, set any needed options: pages, resolution, image size, maximum width, maximum height, and auto orient.
3. Start the conversion and download the resulting PNG file or files.

The conversion runs on the server with LibreOffice, then ImageMagick.

Offline with desktop software

LibreOffice is free and available for Windows, macOS, and Linux. Open the SDA file, then use File → Export, choose PNG as the file type, and save. If an export options dialog appears, set the image dimensions or resolution before confirming.

You can also try the command line with soffice --headless --convert-to png --outdir output drawing.sda, replacing output with an existing destination folder and drawing.sda with your filename. Check the output: import support for older SDA files can depend on the LibreOffice version and the file itself.

Quality and compatibility

PNG conversion rasterizes the drawing, so text and shapes are no longer individually editable. Choose sufficient resolution and image dimensions for the intended display or print size; increasing a small PNG later cannot restore detail. If LibreOffice cannot open the file, the SDA may require an older StarOffice-compatible application before it can be exported.
