What's the difference between my public IP and my local IP?

Your local IP (like 192.168.1.x) is assigned by your router and only visible inside your home network. Your public IP is what the internet sees — assigned by your ISP. My tool shows your public IP. To see your local IP, check your device's network settings.

Why does my IP show the wrong city?

IP geolocation maps your address to your ISP's regional infrastructure, not your exact street. If your ISP routes traffic through a data center in a different city, that's what shows up. VPN users will see their VPN server's location. This is a known limitation of all IP geolocation tools — no tool can show your precise home address from an IP alone.

Can I look up someone else's IP address?

Yes — type any IP into the field and my tool will return its geolocation data. This is useful for checking where a server is hosted, verifying a VPN endpoint, or investigating the origin of a suspicious email or connection.

What is an ASN?

An ASN (Autonomous System Number) identifies the network organisation that owns a block of IP addresses — usually an ISP, cloud provider, or large company. Seeing "AS15169 Google LLC" means the IP belongs to Google's network infrastructure.

Format vs. Validate vs. Minify — which should I use?

Format makes your JSON human-readable with indentation and highlights. Use it when reading API responses or debugging configs. Validate tells you whether your JSON is syntactically correct without reformatting it — useful for CI checks or before sending a payload. Minify strips all whitespace to reduce file size — ideal before embedding JSON in production code or HTTP requests.

Why does my JSON say "invalid" even though it looks right?

The most common culprits are: a trailing comma after the last item in an array or object (valid in JavaScript, invalid in JSON), single quotes instead of double quotes around strings, an unquoted key, or a comment (JSON doesn't support // comments). My validator tells you the exact character position where the error occurs.

Is there a size limit for my JSON?

No hard limit — my formatter runs client-side in your browser's JavaScript engine, so performance depends on your device. In practice it handles files up to several megabytes without issue. Very large payloads (10MB+) may be slow to render with syntax highlighting — use Minify mode for those.

Why does my iPhone save photos as HEIC instead of JPG?

Apple switched to HEIC (High Efficiency Image Container) as the default format in iOS 11 because it produces files roughly half the size of JPEG at the same visual quality — meaning more photos fit on your device. You can force JPG at Settings → Camera → Formats → Most Compatible, but you'll lose the storage efficiency. For existing HEIC photos, my converter is the fastest option.

JPG or PNG — which should I pick for output?

For photos, choose JPG at 88–95% quality. JPG's lossy compression is invisible at those levels and produces small files perfect for sharing, uploading to social media, or sending by email. Choose PNG only if your photo contains text, sharp geometric shapes, or you need pixel-perfect quality with no compression artefacts — PNG files will be significantly larger.

Will this work on my iPhone or Android?

Yes. My HEIC converter runs in Safari on iOS (17+) and Chrome on Android. On iOS Safari 17+, native HEIC decoding is supported — your photos convert perfectly. On older browsers, a compatibility notice appears instead of a broken result.

How many files can I convert at once?

No hard limit — select or drop as many files as you like. They process one by one with a progress bar. Each converted photo appears as a preview with an individual download link, plus a Download all button when the batch finishes.

What exactly is a Lottie animation?

Lottie is an open-source JSON-based animation format created by Airbnb. It describes vector animations exported from Adobe After Effects — things like loading spinners, success states, onboarding illustrations, and animated icons. Because it's JSON-based, the files are tiny, scalable to any resolution, and interactive. It's the standard animation format for web, iOS, and Android apps in 2026.

Where can I get free Lottie animations?

LottieFiles.com is the biggest library — thousands of free community animations. Download any as a .json file and drop it onto my player, or paste the LottieFiles CDN URL into the URL field and click Load. Google's Material Symbols also ships Lottie versions of its icon set.

How does my live color editor work?

My tool walks through the Lottie JSON structure and finds every solid fill and stroke color value. Each one gets a color picker. When you change a color, I patch the JSON in memory and reload the animation with the new values — you see the change live within a fraction of a second. Hit Export to download your edited animation as a new .json file.

Can I use this to check animations before shipping to production?

Absolutely — that's exactly what I use it for. Test on a white, black, or transparent background to make sure your animation looks right in every context. Use the speed slider to spot timing issues. Check the frame count and duration to verify the animation spec matches what your developer expects.

How many words should my blog post be for SEO in 2026?

It depends on the intent. For competitive, informational queries, comprehensive posts of 1,500–3,000 words tend to rank best — they give Google enough signal that the content is thorough. For highly specific queries ("what is X"), 500–800 tightly written words can outrank a bloated 3,000-word post. The best answer: match the length of pages already ranking for your target keyword, then add more value.

What are the character limits I actually need to know?

Google meta description: 155–160 characters (my counter helps you nail this). Twitter/X: 280 characters per post. LinkedIn posts: 3,000 characters, but the "see more" cutoff is ~210. Instagram captions: 2,200 characters, but only 125 show before the fold. YouTube descriptions: 5,000 characters, but only the first 100–150 appear in search results. Email subject lines: 40–60 characters to avoid mobile truncation.

How is reading time calculated?

My tool uses an average silent reading speed of 238 words per minute — the figure from a widely cited 2019 study across 17 languages. Speaking time uses 130 words per minute, which is a comfortable presentation pace. Both are estimates; actual speeds vary by reader and content complexity.

What does the keyword frequency section do?

It counts how often each word appears in your text, after stripping common stop words (the, a, is, was, etc.). The top 12 most-used meaningful words are shown. This helps you spot if you're over-relying on one word, or if your target keyword is appearing too rarely. It's a lightweight SEO check — not a replacement for proper keyword research tools, but useful for in-the-moment writing decisions.
