🔐Password GeneratorFree online random password generator: choose length, character sets and look-alike exclusions, generate several at once with a strength meter, all locally.🎫JWT DecoderFree online JWT decoder: decode the header and payload of a JSON Web Token, show expiry and issued-at times, all locally without uploading the token.#️⃣Hash / ChecksumFree online hash calculator: SHA-1, SHA-256, SHA-384 and SHA-512 of text or any file through the browser crypto API. Files never leave your device.🟫Blur / Pixelate ImageFree online image redaction tool: drag to mark any area and hide it with pixelation, blur or a black box — several areas at once, for faces and plates.🕵️Remove EXIF DataFree online EXIF viewer and remover: see the camera, capture time and GPS location hidden in a photo, then strip the metadata losslessly before sharing.💳ID Card CopyFree online ID card copy maker: front and back laid out at the real 85.6×54mm on one A4 page, with an optional anti-misuse watermark. Export JPG or PDF.🔒Encrypt PDFFree online PDF encryption: set an open password and restrict printing, copying, editing and annotating with AES-256. Everything runs on your device.🔓Unlock PDFFree online PDF unlocker: enter the password you already know and export a PDF without it, or lift owner-only limits on printing and copying. Runs locally.🏷️Edit PDF PropertiesFree online PDF metadata editor: view and change the title, author, subject and keywords, or wipe every property and timestamp for privacy. Runs locally.⬛Redact PDFFree online PDF redaction: draw boxes over names, ID numbers or amounts and black them out for good — those pages are re-rendered so the text is gone.🙈Blur FacesFree online face blurring: AI finds every face in a photo, including small ones in group shots, and pixelates, blurs, blacks out or covers them with an emoji.🕵️Image SteganographyFree online image steganography: hide a message in the least significant bits of a PNG, optionally AES-256 encrypted, and reveal hidden text again.🔒Text Encryption & DecryptionFree online text encryption: AES-256-GCM or CBC with a password (PBKDF2, OpenSSL-compatible output), raw key + IV mode, RSA-OAEP and HMAC signatures.🔏JWT Generator & SignerFree online JWT generator: edit the header and payload, sign with HS, RS, PS or ES 256/384/512, make RSA / EC key pairs, and verify with exp/nbf checks locally.🧼Sanitize PDFFree PDF sanitizer: find and remove JavaScript, auto-run and launch actions, links, attachments, comments, forms and metadata, with a before/after report.🛡️Password Strength CheckerTest password strength privately in your browser: entropy and crack time, detects common passwords, keyboard walks, dates and l33t, optional breach check.🕰️EXIF EditorFree EXIF editor: view all JPEG tags, change or bulk-shift the date taken, set or remove GPS, edit camera, artist and copyright, with no recompression.🧂Bcrypt Generator & CheckerGenerate and verify password hashes online: bcrypt (cost 4–14, $2a/$2b/$2y), Argon2id, scrypt and PBKDF2, auto-detecting PHP, Django, Flask and passlib formats.🛂SSL Certificate DecoderDecode SSL/TLS certificates online: subject, issuer, days to expiry, SANs, key usage, OCSP/CRL, SCTs and SHA-256 fingerprints, with chain and signature checks.🗝️TOTP GeneratorGenerate and verify TOTP / HOTP 2FA codes from a Base32 secret or otpauth:// URI. SHA1/256/512, 6–8 digits, custom period, countdown, new secrets and QR codes.🫥Blur Faces in VideoFree online video face blur: AI detects and tracks every face to blur or pixelate it; keep chosen faces, add regions by hand, export MP4 with audio.🚪Htpasswd GeneratorGenerate .htpasswd entries with bcrypt, APR1-MD5, SHA-512/256 crypt or {SHA}, merge into existing files, verify passwords and get nginx / .htaccess config.🔑Classical Cipher LabEncode and decode Caesar/ROT13, Vigenère (with Kasiski auto-crack), Playfair, rail fence, affine, Bacon and substitution ciphers, plus an Enigma I simulator.🦺HTTP Security Headers CheckerPaste raw HTTP response headers to get an A+ to F grade with checks for HSTS, CSP, X-Frame-Options, cookies, CORS and more, plus fixes and a CSP builder.💠SSH Key GeneratorGenerate SSH key pairs in your browser: Ed25519, RSA 2048/3072/4096 or ECDSA, with OpenSSH keys, passphrases, PKCS#8, fingerprints and randomart.🎖️PDF Signature VerifierVerify PDF digital signatures: recompute digests, check RSA/ECDSA signatures, view the certificate chain, timestamps and LTV data, and spot edits after signing.👻Invisible Character DetectorDetect and remove zero-width characters, bidi controls (Trojan Source), non-breaking spaces, soft hyphens, control chars, homoglyphs and full-width letters.🔐ZIP PasswordFree online tool to password-protect a zip or strip the password from one you can open: AES-256 or ZipCrypto, with garbled filenames repaired on the way.✅File ChecksumFree online checksum tool: compute MD5, SHA-1, SHA-256 and CRC32 for several files at once, compare against a published value and handle multi-GB files.📡Peer-to-peer sendFree peer-to-peer file transfer: scan one QR code to pair a phone and a computer, then files go straight between them — no upload and no size limit.📱China Phone Number CheckFree checker for Chinese mobile numbers: validate the format, identify the carrier by prefix, flag MVNO, IoT and satellite ranges, and export them as CSV.
