MD5 is collision-broken and unsuitable for password storage, signatures or adversarial integrity verification. It remains useful for legacy non-security checksums. Text is UTF-8 without normalization. Files are raw bytes, up to 512 MiB, processed in 2 MiB chunks.
Processing uses your browser memory. Inputs are not included in page analytics. Text tools accept up to 200,000 UTF-8 bytes unless a tighter limit is stated. Worker operations time out after 45 seconds and can be cancelled. Clipboard and downloads require an explicit action.
Enter your values locally; no inputs are uploaded.
Check validation feedback before reviewing the browser-generated result.

No. MD5 is fast and collision-broken. Do not use it for password storage, digital signatures or adversarial integrity verification. This tool supports legacy non-security checksum workflows.

Processing takes place locally in browser memory. Inputs are not sent to a processing service, persisted by this tool or included in analytics. Ordinary page requests may still be logged. Clipboard and downloads require explicit actions.

The exact input is encoded as UTF-8 without Unicode normalization. Spaces, newlines, a byte-order-mark character and different normalization forms can produce different digests.
No. A local Worker reads raw file bytes incrementally in 2 MiB chunks with progress reporting. The file size limit is 512 MiB and Worker processing has a 45-second timeout.
The empty byte sequence produces d41d8cd98f00b204e9800998ecf8427e. Empty text is valid input rather than a missing-data error.
No. An expected checksum must contain exactly 32 hexadecimal digits, and comparison ignores letter case. Uppercase output changes presentation rather than the digest value.
No. Only the raw file contents are hashed. Renaming an unchanged file does not change its digest, while any changed byte may change the digest.
