Archive Processing API
Scalable archive REST API to compress and extract files using TAR, ZIP, and GZIP.
1 Upload your file
Firstly, your file must be uploaded or accessible to Bytescale:
Use the Bytescale Dashboard to upload a file manually.
Use the Upload Widget, Bytescale SDKs or Bytescale API to upload a file programmatically.
Use our external storage options to process external files.
2 Build your archive URL
Build an archive processing URL:
Get the raw URL for your file:
https://upcdn.io/W142hJk/raw/example.zip
Replace "raw" with "archive":
https://upcdn.io/W142hJk/archive/example.zip
Add querystring parameters to control the output:
https://upcdn.io/W142hJk/archive/example.zip?m=extract
3 Download your file(s)
When archiving files, the response will be the archived/compressed file:
https://upcdn.io/W142hJk/archive/example.jpg?m=archiveWhen extracting files, the response will be a JSON object containing links to each extracted file:
https://upcdn.io/W142hJk/archive/example.zip?m=extract{ "files": [ { "size": 12, "artifact": "/example-file.txt" }, { "size": 962594, "artifact": "/example-image.jpeg" } ]}To download each file, append &artifact=<artifact_path> to the URL:
https://upcdn.io/W142hJk/archive/example.zip?m=extract&artifact=/example-file.txtAPI Reference
Use the Archive Processing API to compress and extract files on demand.
The total size of the file archive and its contents must not exceed 10GB.
m=archive
Archives the file.
Response is the archived file, in the format specified by the out parameter.
m=extract
Extracts the file archive.
Response is a text file containing a list of file sizes and relative file paths, which you can download using the artifact query parameter.
c=<int>
Only applicable to m=archive with out=zip or out=tar.gz.
Sets the compression level for the resulting file archive.
•0 = lowest compression and largest file size.
•9 = highest compression and smallest file size.
Note: compression works best with uncompressed content, such as raw images, uncompressed videos, and text, as these files typically contain repeated characters and bytes that compression algorithms are good at reducing. Image formats like JPGs, PNGs and WebP are by design already compressed, so ZIP and other lossless compression algorithms won't be effective at reducing the size of these files any further. This means you'll get similar file sizes when setting c=0 vs. setting c=9 when archiving files such as JPGs.
Formats
Use the in and out parameters to specify the file archive format:
in=tar
Input file will be treated as a .tar archive when using m=extract.
in=tar.gz
Input file will be treated as a .tar.gz archive when using m=extract.
in=zip
Input file will be treated as a .zip archive when using m=extract.
out=tar
Output file will be saved as a .tar archive when using m=archive.
out=tar.gz
Output file will be saved as a .tar.gz archive when using m=archive.
out=zip
Output file will be saved as a .zip archive when using m=archive.
f=json
Generates a JSON index file to list the archive's contents when using m=extract.
f=text
Generates a text index file to list the archive's contents when using m=extract.
Paths
Only applicable to m=archive:
Use dest to specify the location to save the primary file to within the output archive.
Use file and file-dest to add additional files to the output archive.
dest=<string>
The destination path to save the primary file to in the resulting file archive.
Must include a "/" prefix.
file=<string>
Additional file to add to the resulting file archive.
You may specify this parameter multiple times.
To use: specify the "file path" attribute of another file as the query parameter's value.
file-dest=<string>
The destination path to save the additional file to in the resulting file archive.
You may specify this parameter multiple times: once per file parameter.
Must include a "/" prefix.
Requires: file
