To convert other file formats to the "Microscopy Data" file type, you need software like AmScope Software or a similar tool.
About ASA files
The .ASA file extension represents a significant file format collision, most frequently functioning as an annotated scientific image generated by Aquinto or AmScope microscopy software. These files are not simple bitmaps; they act as containers holding high-resolution raster data alongside proprietary layers for calibration, measurements, and vector annotations. The primary constraint users face is proprietary lock-in: .ASA images cannot be rendered by standard web browsers, Adobe Photoshop, or generic image viewers. To include these micrographs in research papers or share them with colleagues who lack the specific lab software, you must convert them to interoperable formats like TIFF (for uncompressed archiving), PNG (for web presentation), or PDF (for reports).
Note on Text Files: A distinct but historically significant variation is the global.asa file used in Classic ASP environments. These are plain text configuration files used by Microsoft IIS to handle server-side application events. If your file is a few kilobytes in size and contains readable code, do not convert it as an image; simply open it with a text editor like Notepad++.
Convert.Guru analyzes your ASA file, detects the exact format, and lets you read the text inside.
If you want to convert ASA file to FTD, DIN, ISO, HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP or JSPX, you can use AmScope Software or similar software from the "Scientific Microscopy Imaging" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to ASA, try AmScope Software or another comparable tool in the "Scientific Microscopy Imaging" category.
The ASA Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ASA converter.
