RSRC Viewer Online - Mac Resource Fork Extractor
Extract Macintosh RSRC files online. Browse extracted files, open supported icons, pictures, sounds and text, and download resource data.
Browse a Macintosh resource fork
A Macintosh resource fork holds typed records such as icons, pictures, sounds, strings and application data. Upload a raw .rsrc file or an AppleSingle/AppleDouble wrapper to extract its files. Browse the file list and click a PNG, audio file or text file to open it. Original resource bytes are available in the resources folder; types, signed IDs, names and sizes are recorded in the metadata JSON.
Supported resources and limits
Supported previews include ICNS icon families, classic bitmap icons, supported PICT and color icons, sound resources, text and other resources understood by the converter. Coverage depends on the resource type and encoding. Unknown resources retain their raw downloads. Custom decompressor code from the uploaded file is not used; resources requiring it may remain compressed.
Input files are limited to 64 MiB, 256 resource types and 1024 resource records. Previews are limited to 4096 pixels per side and 16 million pixels per job. Export limits are 64 MiB per file, 256 MiB total and 4096 files, with a two-minute processing deadline. Partial results identify resources without a preview.
How do I open an RSRC file on Windows or Linux?
Use Choose RSRC above. The resource browser runs on our servers and returns images, audio, text and downloadable data that you can inspect in your browser.
Can I extract Mac icons from an RSRC file?
Yes. Open the images or converted folder and click a PNG to preview or download it. An extracted ICNS file also opens in the ICNS viewer to list its supported image variants.
Which resource files does this page open?
This page is for Macintosh Resource Manager files and resource forks in AppleSingle/AppleDouble containers. Other formats that use the same extension are not supported here. A resource fork lost during copying cannot be reconstructed from an empty file. If you have the original disk image, try the DMG extractor; packaged application files can also be browsed with the macOS PKG extractor.
