Frequently Asked Questions
Is this tool completely free?
Yes! File Gulp provides completely free file conversion tools with no hidden fees, no watermarks, and no registration required.
Are my files safe?
Absolutely. Unlike other converters, File Gulp uses modern WebAssembly technology to convert files directly on your device. Your files never leave your computer, ensuring maximum privacy.
Does it work on mobile devices?
Yes, our tool is fully responsive and works perfectly on smartphones and tablets, directly from your mobile browser.
Will the quality be affected?
No, we use high-quality algorithms to ensure your output files maintain the best possible quality during conversion.
Is there a file size limit?
Very large files may be limited by your device memory/browser performance. For normal image sizes, conversion is fast and seamless.
Free online hash generator for text and files
Use this Hash Generator to create MD5, SHA-1, SHA-256, SHA-384, and SHA-512 checksums directly in your browser. It is designed for developers, website owners, students, and anyone who needs to verify a downloaded file, compare two pieces of text, check API payload changes, or create a quick checksum without uploading private data.
What is a hash?
A hash is a fixed-length fingerprint generated from text or a file. The same input creates the same hash every time, while even a tiny change creates a different value. That makes hashes useful for file integrity checks, download verification, duplicate detection, cache keys, and development workflows.
Why generate hashes locally?
Files used for checksums can contain source code, backups, contracts, archives, documents, or private exports. This tool reads your input with browser-native APIs and calculates the result in local memory, so your text and files are not uploaded to a server.
Which hash algorithm should I choose?
- SHA-256: Best default choice for modern file verification, software downloads, API checks, and security-aware workflows.
- SHA-512: Stronger and longer output, useful when a system or download page specifically provides SHA-512 checksums.
- SHA-384: A SHA-2 family option sometimes used in enterprise, TLS, and compatibility workflows.
- SHA-1: Useful only for old systems and legacy checksums. Do not choose it for new security-sensitive designs.
- MD5: Fast and still common on old download pages, but not secure against deliberate tampering. Use it only when you need to compare with an existing MD5 value.
Text and file hashing
Paste text, code, JSON, tokens, or select any local file and generate multiple hash values from the same input.
Instant verification
Paste a checksum into the compare field and the matching result is highlighted automatically after generation.
Easy export
Copy a single result, copy all generated checksums, switch lowercase or uppercase output, or download a TXT report.
No account, no upload
The tool is free to use in the browser, with no registration and no server-side file processing.
Common use cases for a hash generator
- Verify downloads: Compare a file checksum with the MD5, SHA-256, or SHA-512 value published by the software provider.
- Check file integrity: Confirm that a backup, ZIP archive, image, PDF, or installer has not changed after transfer.
- Debug development changes: Hash API payloads, JSON strings, scripts, CSS files, build outputs, and cache keys.
- Compare text safely: Generate a fingerprint for text without exposing the original content to an external server.
