About this file hash checker

A SHA-256 checksum is a 256-bit digest that can help detect whether two files contain the same bytes. This checker reads the selected file locally in chunks and calculates its checksum without loading the entire file into memory. It accepts any file type and does not modify the file.

A matching checksum only confirms a match with the checksum you supplied. To check a download, get the expected checksum from the software publisher’s official, trusted source. A match by itself does not prove that the file is authentic or safe to open.

Frequently asked questions

Is my file uploaded or saved?

No. The file is read and hashed locally in your browser. It is not sent to or stored by ToolsLodge.

How do I check whether a file matches?

Paste the SHA-256 checksum published by the software provider. A match means the selected file has the same checksum; a mismatch means the bytes differ or the expected checksum may be incorrect.

Does a matching checksum prove a download is safe?

No. Only compare against a checksum obtained through a trusted, authentic source, such as the provider's official website. A checksum alone does not prove who created a file or that it is safe.

Can I check large files?

Yes. The file is streamed and hashed in chunks rather than loaded all at once. Processing time depends on file size and your device.
