Does my file leave the browser?
No, hashing runs entirely in your browser — files are not uploaded.
FileLumo Tool
Generator hash
MD5, SHA-256, dan lainnya untuk file yang diunggah atau teks yang ditempel. Berguna untuk memastikan file sampai tanpa perubahan.
MD5/SHA-1 are fine for checksums; use SHA-256 or SHA-512 when you need stronger guarantees.
File (optional)
If you upload a file, its bytes are hashed and the text field is ignored.

Generate file and text hashes online
Compute MD5, SHA-1, SHA-256, and SHA-512 hashes from files or text strings in your browser. Useful for verifying that a downloaded file is unchanged.
When to use Hash Generator
- Verify downloaded files match a published hash
- Generate checksums for backups
- Hash passwords for safe sharing
- Confirm software integrity before installing
How it works
- 1Upload a file or paste text
- 2Choose hash type (MD5, SHA-1, SHA-256, SHA-512)
- 3Wait for hash to compute in your browser
- 4Copy or compare the hash
Before you upload to Hash Generator
Check the file you are about to process, especially when it contains contracts, IDs, invoices, payroll details, legal drafts, school records, or client information. FileLumo is designed for quick no-signup workflows, but the safest document workflow still starts with choosing the right file and keeping an untouched original copy.
- Keep a master copy before editing, compressing, converting, or protecting a document
- Remove pages you do not need to share before uploading sensitive packets
- Use a clear filename for the downloaded result so drafts and final copies do not get mixed up
Privacy, limits, and output quality
Most PDF jobs are simple, but edge cases happen: very large scans, unusual fonts, password-protected files, embedded images, and old PDF versions can change the output. After processing, open the result once before sending it to a client, school, court portal, or upload form. Server-side workflows use TLS in transit. FileLumo does not store your files — download your result to keep a copy.
- Use medium or balanced settings first when quality matters more than the smallest possible file
- For strict upload limits, compare the final file size against the portal requirement before submitting
- For confidential documents, review your organization policy before using any third-party online tool
Frequently asked questions
Which hash should I use?
Use SHA-256 or SHA-512 for security. MD5 is faster but not collision-resistant.
Is the hash generator free?
Yes, free with no signup and no limits.
