Does my file leave the browser?
No, hashing runs entirely in your browser — files are not uploaded.
MD5 وSHA-256 والمزيد لملف مرفوع أو نص ملصق. مفيد للتحقق من وصول الملف دون تغيير.
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.

Large files may take longer to upload.
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.
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.
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 SHA-256 or SHA-512 for security. MD5 is faster but not collision-resistant.
