About this app

Uncode helps you understand unfamiliar strings and work with everyday text, without an account or a server.

Paste text, type it, or select text from your camera or an image. Uncode suggests possible formats, explains the evidence and shows decoded text when a meaningful conversion is available.

ANALYZE AND DECODE
Explore Base64 and Base64URL, Hex, Binary, ASCII, Unicode escapes, HTML entities and URL encoding. Follow up to five decoding steps and compare alternative interpretations. Inspect JSON, timestamps, URLs, color codes, JWT, UUID and recognizable hash or encrypted-data structures.

WORK WITH TEXT
Format, minify and explore JSON. Convert Unix timestamps and ISO dates, with UTC and local time. Encode text, change case, clean whitespace, remove duplicate lines, sort lines, replace text and add prefixes or suffixes. Preview changes before applying them to your input.

CAMERA, IMAGES AND QR
Read Latin, Korean, Japanese and Chinese text using bundled on-device OCR models. Choose automatic or manual recognition. Select recognized text, correct it and analyze it. Generate QR codes, save or share PNG images and read QR content from the camera or selected images. Links never open automatically.

YOUR CONTENT, YOUR CHOICE
String analysis and image recognition run on your device. No account, ads or in-app purchases. The clipboard is read only when you tap Paste. Input and results are not automatically saved as a history. Sharing and QR image saving happen only when you choose them; temporary files may remain after image selection or sharing. See the privacy policy for SDK and data-handling details.

KNOW THE LIMITS
A format match is not proof of origin or authenticity. Hashes and key-protected ciphertext cannot be reversed by ordinary decoding. JWT decoding does not verify its signature. OCR may misread characters; review the source before applying a suggestion.

Dark, light and system themes. Interface options for English, Korean, Japanese, Traditional Chinese (Taiwan), Spanish, Brazilian and European Portuguese, German, French and Italian. App translations are AI-generated; your input and decoded content are not translated.
