## What is DevKit?

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. Scanned pages are read with on-device text recognition. Tables are kept on iOS 26 and later.
> JPG to PDF: Combine photos and scans into one tidy PDF
> HEIC to JPG: Turn iPhone photos into JPGs for forms and websites
> MOV to MP4: Turn .mov videos into .mp4 files
> HTML Viewer: Open .html files safely and see their source
> JSON, XML and CSV Viewers: Open data files as a tree or a table
> Unzip and Zip Files: Open .zip archives, or bundle files into one
> Open files straight from the Files app, Mail or Safari, and find everything you convert in the Files tab

FORMATTERS
> JSON Formatter: Format, minify and validate JSON, with a collapsible tree view
> HTML, CSS, JavaScript, XML and SQL Formatters

ENCODE & DECODE
> JWT Debugger: Decode tokens, inspect headers and claims, verify signatures
> Certificate Decoder: Read X.509 certificates
> Base64, URL Encoder and Parser, HTML Encoder, Backslash Escape
> Hash Generator: MD5, SHA-1, SHA-256 and SHA-512

CONVERTERS
> Timestamp, Case Converter, Color Converter (HEX, RGB, HSL)
> YAML to JSON, CSV to JSON, Number Base, Hex to Text
> Cron Parser: Read cron expressions in plain English, with the next run times

GENERATE & COMPARE
> QR Code: Scan codes live with the camera or from a photo, and create your own
> UUID and ULID Generator, Random String, Lorem Ipsum
> Diff Checker, RegEx Tester, Markdown Previewer, Line Sort, String Inspector

MADE FOR YOUR PHONE
> History reopens your recent runs, stored only on your device
> Paste, copy and share in one tap
> Light and dark designs, large text and VoiceOver support
> No account and no sign-up

PRIVACY
The tools process your text and files on your device. DevKit uses analytics to learn which tools are used (never what you put in them); you can turn it off in Profile > Privacy & Data.

SUBSCRIPTION
DevKit Pro unlocks every tool, as a monthly or yearly auto-renewing subscription. The price for your country is shown in the app before you buy. Eligible new subscribers get a free trial. Payment is charged to your Apple ID account when you confirm the purchase, or when the trial ends. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
