How to encode a URL on iPhone (no app to install)
Mobile Safari runs the full URL Encoder / Decoder in your browser — no App Store download, no upload, no account.
One reason people install third-party apps on their phone is that they don't realise the same tool runs perfectly in mobile browsers. URL Encoder / Decoder is browser-only — no app store, no install — and it works exactly the same on iPhone as it does on a laptop.

Step-by-step on iPhone
- Open Safari and go to URL Encoder / Decoder.
- Tap "Choose file" (or drag from the Files app if you're in split-screen on iPad).
- Pick the URL from Photos, iCloud Drive, or Files — they all work.
- Set your options (sizes, quality, output format). Tap "Run" or whatever the equivalent button is for URL Encoder / Decoder.
- Save the result. Safari downloads to the iCloud Drive Downloads folder by default; tap the result and choose "Save to Files" if you need it somewhere specific.
- AirDrop or share it straight from the Files share menu — useful if the URL is going to a Mac next.
Useful iOS-specific tricks
- Add URL Encoder / Decoder to your home screen to make it feel like a native app: tap the share button in Safari, scroll to "Add to Home Screen." It launches in its own window, no browser chrome.
- Use the Files app for batch input — select multiple URLs in Files, tap Share → Open in Safari, and URL Encoder / Decoder picks them all up at once.
- Photos library access works the same as any iOS app, but with no permissions to grant separately.
Run it in your browser

Why a browser tool beats most native apps for this
Native apps that encode URLs are almost all just wrappers around browser-class libraries. They usually upload your file to their server, which is slower, less private, and sometimes paywalled. URL Encoder / Decoder does the work directly in your phone's browser engine — same code path that would run if you were on a desktop, no upload, no signup, no daily limit.
Frequently asked questions
Can URL Encoder / Decoder access my iCloud Photos?
Only when you pick a file through the standard system file-picker. The browser sandbox prevents any app — including URL Encoder / Decoder — from reading your library without an explicit selection.
Why isn't there a "URL Encoder / Decoder" app on the App Store?
Because there doesn't need to be. Mobile browsers run the same WebAssembly the desktop site uses. Shipping a native app would mean maintaining two codebases for the same feature.
Does it work on older iPhones?
Anything from the last five years handles URL Encoder / Decoder comfortably. Older devices may take longer for big files, but the underlying APIs (WebAssembly, FileReader) have been stable for years.
Is my URL private when I use a browser tool?
Yes — more private than most apps, because nothing is uploaded. The URL is processed entirely inside the browser tab and is gone the moment you close it.
