Base64 Encode Decode

Features
Read full description

Encode and decode Base64 right on your iPhone โ€” paste text or encoded data and watch it flip both ways in real time, with a live byte count on every result. Base64Tool is a full developer codec workbench, not a single-trick converter. Beyond standard Base64 it handles the encodings you actually hit while shipping โ€” URL-safe Base64, percent-encoding, HTML entities, Hex, and Base32 โ€” plus a JWT inspector and an image-to-data-URI converter, all running entirely on-device with nothing sent to a server. WHAT YOU GET - Instant two-way Base64 encode and decode with a live byte and size readout - A whole codec set: Base64URL, URL percent-encoding, HTML entities, Hex, and Base32 - A JWT decoder that splits any token, pretty-prints the header and payload, and surfaces claims and expiry - An image converter that turns any photo into a Base64 data-URI for HTML, CSS, or JSON โ€” and pastes one back to preview - Saved history so you can pull up a past conversion without retyping it - A built-in reference that explains Base64, data-URIs, and JWTs in plain language PERFECT FOR - Web and API developers wiring up tokens, payloads, and query strings - Mobile and backend engineers debugging encoded data on the go - DevOps and security folks inspecting JWTs and Base32 secrets - Students learning how encodings actually work under the hood WHY NOT JUST USE A WEBSITE? Online encoders make you paste sensitive tokens and payloads into someone else's server. Base64Tool does every conversion locally on your device โ€” no upload, no account, no waiting on a network โ€” so a private key or auth token never leaves your phone. PRIVACY Everything runs on-device. No accounts, no servers, no tracking, and your saved history stays inside the app. Your payloads never leave your iPhone. FULL ACCESS Standard Base64 encode and decode is free forever. Unlock everything else โ€” the Base64URL, URL, HTML, Hex and Base32 codecs, the JWT decoder, and the image data-URI converter โ€” with Base64Tool Pro: - Weekly plan - Yearly plan - Lifetime (one-time purchase) Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends; manage or cancel anytime in your App Store account settings. Paste your first string and watch it decode instantly. Terms of Use (EULA): https://web-levi.web.app/terms Privacy Policy: https://web-levi.web.app/privacy-policy Questions?
