7Z, RAR or ISO to ZIP

• Choose one supported archive within its input limit.
• For encrypted 7Z/RAR, enable the known-password option and enter the password; one password must unlock every entry.
• Choose inspection, extraction or ZIP conversion. Inspection and selected extraction still verify the entire archive.
• For ISO choose its filename namespace; the password controls do not apply to ISO.
• Download only after all checks pass. Files and ZIP output are unencrypted. Cancel stops the worker; Reset clears local input and results.

Open a header-encrypted solid archive with its known password, verify its complete contents, then extract selected files or convert all supported entries to an unencrypted ZIP.

• ISO permits 128 MiB input; 7Z/RAR permit 20 MiB. All archives: 1,000 entries, 16 MiB per entry, 64 MiB combined decoded file content, 256 MiB native heap and 120-second worker deadline. Individual extraction allows 100 downloads. Browser input/output copies are separate from the native heap.
• One supplied password of at most 127 UTF-16 code units, without NUL; supplementary characters count as two. An explicitly supplied empty password is allowed. No guessing, cracking or recovery. Mixed-password archives fail without partial output.
• Supports common 7Z LZMA/LZMA2, PPMd, stored, Deflate and BZip2 data and supported RAR3/4/RAR5 encryption and solid layouts. RAR5 dictionaries are capped at 64 MiB. Unsupported codecs or larger memory/work requirements fail explicitly; encrypted RAR7 variants are outside the tested scope.
• Split volumes, self-extracting executables, links, alternate streams, special files, unsafe/non-normalized paths, duplicate names and Unicode/case collisions are rejected. Nested archives are not expanded. No file is executed.
• All entries must completely decode and pass available archive integrity checks before a result. This does not establish origin or imply every archive entry contains a checksum. Downloads and ZIP output are unencrypted and omit timestamps, permissions and archive metadata. Individual downloads flatten folders with numbered prefixes.
• The verified engine and its complete corresponding source/relink materials are versioned local assets. Selected file bytes and supplied passwords stay in the browser. JavaScript password strings are not claimed to be securely erasable.
• ISO supports plain ISO9660, Joliet and Rock Ridge regular files and folders. It has no general file-content checksum: bounded structural checks and complete reads do not authenticate contents. Bootability, partition information and filesystem metadata are omitted; ISO version suffixes and plain ISO trailing dots are normalized.
• ISO has a 64-level directory depth, 8 MiB combined directory/continuation budget and complete matching multi-extent requirement. UDF, split/raw-sector images, linked or relocated Rock Ridge directories, interleaving, extended attributes, zisofs and appended sessions are unsupported.
