Convert files and debug code in one app. DevKit turns PDFs into editable Word documents, photos into PDFs and HEIC photos into JPGs, and gives developers a full kit of formatters, decoders and generators. Everything runs on your iPhone or iPad: your files are never uploaded. FILE TOOLS > PDF to Word: Turn a PDF into an editable Word document (.docx), keeping headings, lists, links, images, headers and footers. Preview the result before you save it.

Base64 Encode Decode
Read full descriptionHide full description
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 - 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 — 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 — 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 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?
