Hash Generator

Hash text or an entire file and get hex digests for SHA-1, SHA-256, SHA-384, SHA-512, and MD5. SHA family digests come from the native Web Crypto API. Everything happens locally in your browser: nothing is uploaded, stored, or logged.

Known limitations

MD5 and SHA-1 are included for checksum compatibility only — neither is safe for security purposes.

FileForge is bringing FFmpeg entirely inside your browser tab — nothing uploads. Enable this tool by turning on cross-origin isolation in your deployment (see ffmpegwasm.netlify.app), or use the desktop CLI in the meantime.

About Hash Generator

Hash text or an entire file and get hex digests for SHA-1, SHA-256, SHA-384, SHA-512, and MD5. SHA family digests come from the native Web Crypto API. Everything happens locally in your browser: nothing is uploaded, stored, or logged. This focused Hash Generator page is designed for developers and download recipients comparing checksums or identifying changed text and files. It opens directly to the working tool, rather than hiding the function inside a general converter or account dashboard.

The source is evaluated by a purpose-built parser or browser API in the current tab; it is not submitted to a remote formatter, compiler, or logging service. Your filename and file contents stay on the device. There is no upload queue, temporary cloud copy, account record, or server-side conversion job to delete later. That makes the tool practical for personal records, work material, and drafts that should not be handed to an unknown processing service.

The important limitation is straightforward: MD5 and SHA-1 are included for checksum compatibility only — neither is safe for security purposes. Knowing that boundary helps you choose the right source file and check the result before relying on it. Processing speed and maximum size depend on your browser and available device memory, which is the honest trade-off for doing the work locally.

FileForge charges nothing for this tool and does not add a watermark. Once the page and its processing engine have loaded, the operation can continue without sending the file over the network. Use the numbered steps below, download the result, and review it before replacing an original file.
