About Base64 Encoder Decoder JWT
Encode and decode Base64 right on your iPhone — 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 — URL-safe Base64, percent-encoding, HTML entities, Hex, and Base32 — 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 (RFC 4648)
- Human-readable error messages when something won't decode, so you know exactly what's wrong
- A JWT decoder that splits any token, pretty-prints the header and payload, and surfaces claims, expiry and signature
- An image converter that turns any photo into a Base64 data-URI for HTML, CSS or JSON — and pastes one back to preview
- Saved history so you can pull up a past conversion without retyping it
- One-tap copy, a clean dark-mode interface, and a quick personalisation step during onboarding
- 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 — no upload, no account, no waiting on a network — 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 — the Base64URL, URL, HTML, Hex and Base32 codecs, the JWT decoder, and the image data-URI converter — with Base64Tool Pro:
- Weekly plan
- Yearly plan
- Lifetime (one-time purchase)
Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled 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.
