URL Inspector & Link Tester vs Base64 Encode Decode Offline

URL Inspector is the developer's Swiss Army knife for links. Break down any URL into its components, test deep links, trace redirect chains, compare parameters side by side - all entirely on your device. Your URLs never leave your phone. Whether you're debugging a campaign link, verifying a deep link integration, or tracing a redirect chain, URL Inspector gives you instant answers without opening a browser or spinning up a terminal. --- INSPECT ANY URL --- Paste a URL and instantly see every component: scheme, host, path, fragment, and all query parameters. URL Inspector automatically classifies parameters into 10 categories: - UTM (source, medium, campaign, term, content) - Attribution / Network IDs (gclid, fbclid, ttclid) - Deep Link (target, fallback, deferred) - Session & User IDs - Nested URLs (encoded redirect targets) - Pagination, A/B Test, Duplicate, Empty Toggle between raw percent-encoded values and decoded text. Edit any parameter inline and watch the URL rebuild in real time. Copy individual values, keys, or the full URL with a long press. --- TEST DEEP LINKS --- Verify that your custom URL schemes (myapp://) and universal links actually work - before you ship. URL Inspector tests each link and reports the result: - Opens in App - Opens in Safari - Cannot Open - Universal Link Detected Save, pin, and organize your most-tested links. Batch manage with multi-select, swipe actions, and sort options. --- TRACE REDIRECT CHAINS (Pro) --- Follow any URL through its full redirect chain — up to 20 hops. See every detail for each hop: - HTTP status code (301, 302, 307, 308) - Meta-refresh and JavaScript redirects - Response time per hop - Resolved IP address and server info - Custom User-Agent selection Share the full chain as an image or text. Perfect for debugging short links, affiliate URLs, App Store redirects, and marketing funnels. --- COMPARE URLs (Pro) --- Compare 2 to 5 URLs side by side. Instantly see which parameters are shared, which differ, and which are missing. Clear visual diff highlighting shows uniform, changed, and partial matches. Ideal for comparing campaign variants, A/B test URLs, or tracking link versions. --- ENCODE & DECODE (Pro) --- Strict percent-encoding for any text, or recursive decoding that unravels even deeply nested encoded URLs. Send results directly to Inspect, Compare, or Link Tester. --- URL CLEANING (Pro) --- Remove UTM parameters, tracking IDs, and attribution tags with one tap. Get clean, shareable URLs instantly. --- ACTIVITY HISTORY --- Every inspection, test, comparison, and redirect trace is saved to a unified timeline. Search through your history, star favorites, and filter by tool type. Pro users get unlimited history, full search, and iCloud sync across all devices. Free users get the last 5 items. --- EXPORT (Pro) --- Export any result as JSON, CSV, or plain text via the native share sheet. Share with your team or save for documentation. --- WHY URL INSPECTOR? --- - 100% on-device — URLs never leave your phone - Works offline (except Redirect Checker) - No account required - No ads - iCloud sync for Pro users - Built natively with SwiftUI for iPhone and iPad --- FREE vs PRO --- Free: - Full URL inspection with parameter classification - Deep link and universal link testing - 5 saved links, 5 history items Pro (unlock everything): - URL Comparison (2-5 URLs) - Redirect Checker with full chain tracing - URL Encoder/Decoder - URL Cleaning - Unlimited history, search, favorites - iCloud sync across devices - Advanced export (JSON, CSV, text) Download URL Inspector free and break down your first URL in seconds. ------ Privacy Policy: https://apps.timurd.com/urlinspector/privacy_policy.html Terms of Use: https://apps.timurd.com/urlinspector/terms.html FAQ: https://apps.timurd.com/urlinspector/#support

Paste a Base64 string, tap once, read the answer — right on your iPhone, fully offline. No web converter, no upload, no wondering who just logged the token you pasted. Base64 Encode Decode Offline is a developer scratchpad built for the real thing you paste: blobs copied out of logs and terminals. The decoder tolerates URL-safe alphabets, missing padding and line-wrapped copy-paste, auto-detects whether you meant encode or decode, and refuses garbage instead of returning silent nonsense. URL decoding is byte-accurate, so a leading BOM or odd byte is preserved instead of being quietly eaten. Everything renders in a proper monospaced font. WHAT YOU GET • A wrapped, unpadded, URL-safe Base64 blob from a log file still decodes cleanly — whitespace, CRLF and base64url handled for you • Paste a JWT and read its pretty-printed header and payload immediately — the signature never touches a server • One input, four digests: MD5, SHA-1, SHA-256 and SHA-512 update as you type, with one button to copy all four • URL-encode a query value and the &, =, + and # characters that break query strings are actually escaped • Turn any file into Base64 or a ready-to-embed data URI with the correct MIME type — and turn Base64 back into a file • The String Inspector shows characters, UTF-8 / UTF-16 / UTF-32 byte counts, words and lines the moment text is entered PERFECT FOR • Backend and mobile developers debugging an API payload away from the laptop • QA engineers inspecting auth tokens without pasting credentials into a website • Sysadmins decoding config blobs and verifying checksums from a phone session • Students seeing exactly how encodings and hash digests behave WHY NOT JUST USE A WEB CONVERTER? Because every online encode/decode tool receives your string on its server — and the strings developers convert are exactly the ones that should never leave the machine: session tokens, API keys, connection strings, JWTs. This app does all conversion and hashing on the device with Apple's CryptoKit. It works in airplane mode. PRIVATE BY DEFAULT No accounts, no tracking of your content, no network needed to convert. Your inputs and your conversion history are stored only on your iPhone. FULL ACCESS Pro unlocks unlimited saved conversions, file conversion beyond 5 MB in both directions, and Batch mode to convert many lines in one pass. Full access is available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. Decode that string before the next station — download Base64 Encode Decode Offline.
