7Z: create an archive or a data ISO

A 7Z archive compresses files and folders. A small compressed file can expand substantially. Choose a new 7Z archive for repacking, or a data ISO only when the destination actually needs a disc image.

Available conversions

Choose your task

Create a 7Z archive

ZIP → 7Z repacks the extracted ZIP contents. File types and compression already applied can limit any size reduction.

Create a data image

7Z → ISO extracts files into a new non-bootable data ISO. If the desired ISO is already inside, extract it locally.

Archive is too large or protected

Check the route’s upload limit and unpacked limits. Passwords, multipart inputs and renaming/splitting to bypass the one-file limit are not supported.

Available conversions

7Z → ISO

Put the extracted 7Z files into a new data ISO. Extract an ISO already inside locally.

Upload limit: ≤ 50 MB

ZIP → 7Z

Repack ZIP files into a 7Z archive. A smaller output is not guaranteed.

Upload limit: ≤ 100 MB

Check limits before uploading

One file per task. Compressed size is not unpacked size; processing also has memory and time limits. Files are processed on the server: avoid confidential material. Download before the expiry shown on the result page.

Unpacked data for archive → ISO: ≤ 1024 MB · ≤ 10000 files

Check the result

Compare the files in the downloaded archive or image with the source.
Keep the original and check the result in the application where you need it.

Questions before you convert

Does 7Z → ISO keep an installer bootable?

No. The service builds a new data filesystem rather than preserving the original boot structure.

Will ZIP → 7Z always reduce the size?

No. Already compressed images, video or archives may not become smaller.
