First, refresh the page. If it is still blank, make sure JavaScript is enabled and your browser is up to date — our tools run in the browser and need JavaScript. Temporarily disabling ad blockers or strict privacy extensions for azutils.com can also help, as they sometimes block scripts.

Check that your browser isn't blocking downloads or pop-ups for azutils.com. Some browsers queue downloads quietly — look in your downloads bar or folder. On iPhone and iPad, files usually save to the Files app. If it still fails, try another browser.

Each tool supports specific formats — for example, the image tools work with JPG, PNG and WebP. Confirm your file is a supported type and not corrupted. Because processing happens on your device, very large files depend on your available memory, so try a smaller file or close other tabs.

Compression reduces file size, and at higher levels some quality loss is expected. Use a lighter setting if one is available, and always keep a copy of your original. For graphics with sharp edges or text, PNG or WebP usually look better than heavy JPG compression.

That usually means the JSON is invalid. Common causes are trailing commas, single quotes instead of double quotes, or missing brackets. Use the JSON Validator to pinpoint the line, fix the issue, then format again.

Make sure you pasted the entire token, including all three parts separated by dots (header.payload.signature), with no extra spaces or line breaks. The decoder reads the header and payload locally and does not verify the signature.

Clipboard access needs a secure connection and your permission. AZUtils runs over HTTPS, so allow clipboard access if your browser prompts you. On some older browsers you may need to select the text and copy it manually.

This is usually a caching issue. Do a hard refresh (Ctrl+F5 on Windows, Cmd+Shift+R on Mac) to reload the latest styles. Clearing your browser cache for azutils.com also resolves it.

Our EMI Calculator gives an accurate estimate from the principal, interest rate and tenure you enter. Banks may add processing fees, insurance or taxes, or use slightly different rounding, so small differences are normal. Always confirm the exact figure with your lender.

Large files are processed on your device and can use noticeable memory for a moment. Close unused tabs, try a smaller file, or use a desktop browser for heavy tasks. The pause is temporary and clears once processing finishes.
