Troubleshooting

Try these steps:
• Hard refresh with Ctrl+F5 or ⌘+Shift+R
• Clear browser cache for our site
• Disable browser extensions temporarily
• Try a different browser

If the issue persists, your browser might be outdated - update to the latest version.

JavaScript errors usually indicate a browser compatibility issue. Make sure you're using a modern browser (Chrome 90+, Firefox 88+, Safari 14+, Edge 90+). Try disabling any script-blocking extensions like NoScript. Clear your cache and reload.

This can happen if CSS fails to load properly. Try:
• Hard refresh
• Clear cache
• Check if your zoom level is at 100%
• Disable any CSS-altering extensions

On mobile, try rotating your device.

We support all modern browsers - Chrome (version 90+), Firefox (88+), Safari (14+), Edge (90+), and Opera (76+). Internet Explorer is not supported. Mobile browsers like Chrome for Android and Safari for iOS work great.

For client-side tools, performance depends on your device since processing happens locally. Try:
• Close other tabs and applications
• Process smaller files if working with large ones
• On older devices, avoid batch processing many files at once

Clipboard access requires a secure context (HTTPS) and user permission. Make sure:
• You're using HTTPS (our site always does)
• You've granted clipboard permission if prompted
• You're clicking directly (not using scripts)

Some browsers restrict clipboard in certain contexts.

Check these common issues:
• File size might be too large for your device's memory (try files under 50MB)
• File format might not be supported - check the tool's documentation
• Try dragging and dropping instead of using the file picker
• Make sure you have file access permissions

Each tool supports specific formats. Check the tool's documentation for supported formats. Common issues - file extension doesn't match actual format, file is corrupted, or it's a proprietary format. Try converting to a standard format first.

Try these fixes:
• Check if your browser is blocking downloads
• Try right-clicking and "Save as" if available
• Disable any download manager extensions
• Make sure you have storage space on your device
• Try a different browser

Large files or complex operations can take time. For very large files:
• Wait longer - check if the progress indicator is moving
• Process files in smaller batches
• Close other applications to free up memory
• Try on a more powerful device if available

Common PDF issues:
• The PDF might be encrypted or password-protected - unlock it first
• It might be a scanned document that needs OCR
• The PDF could be corrupted - try opening it in Adobe Reader or Foxit Reader first
• Some proprietary PDF features aren't supported

Image quality depends on the conversion settings. Check:
• Quality slider if available - set it higher
• Output format - some formats (JPEG) are lossy
• Original image quality - we can't improve source quality
• Try PNG or WebP for better quality

QR scanning issues:
• Make sure the code has enough contrast
• Don't make it too small - minimum 2cm x 2cm for printing
• Check that the data isn't corrupted
• For WiFi codes, verify the password and security type are correct
• Test with multiple QR scanner apps

We use the Web Crypto API (crypto.getRandomValues()), which provides cryptographically secure random numbers. This is the same randomness used by banks and security applications. The passwords are generated entirely in your browser.

Common JSON syntax errors:
• Missing or extra commas
• Unquoted keys (JSON requires double quotes)
• Single quotes instead of double quotes
• Trailing commas after last items
• Unclosed brackets or braces

Our formatter shows exactly where the error is.

You can reorder pages before merging:
• After adding files, drag and drop pages to reorder them
• Use the preview to verify the order
• If merging many files, add them in the desired order initially

Color appearance varies between devices. Factors:
• Monitor calibration differences
• Color profile settings
• Viewing angle on some displays
• Browser color management

For precise work, use calibrated monitors and check color values numerically.

Character encoding issues:
• The original text might use a different encoding (UTF-16, ISO-8859-1)
• The base64 might encode binary data, not text
• Try the "File" mode if decoding binary content

Our tool defaults to UTF-8 encoding.

For client-side tools, performance depends on your device since processing is local. Try:
• Close unnecessary browser tabs
• Close other applications
• Restart your browser
• Process files one at a time instead of batches
• Use smaller files if possible

This happens when processing large files that use too much memory. Solutions:
• Process smaller files
• Break large operations into smaller parts
• Close other tabs to free memory
• Try a browser with better memory management (Chrome/Edge usually handles large files better)

Crashes usually indicate memory issues. Your device ran out of available memory during processing. Solutions:
• Use smaller files
• Process fewer files at once
• Close other applications
• Restart your browser or device

There's no fixed limit - it depends on your device's available memory. Guidelines:
• Most modern devices handle up to 50-100MB easily
• Older devices might struggle with files over 20MB
• For very large files (100MB+), expect longer processing times

Try these mobile tips:
• For optimal experience, we recommend phones with at least 6.1" display
• Use landscape mode for tools with complex interfaces
• Use the pinch-to-zoom gesture carefully
• Try the desktop version if your browser offers that option
• Ensure you're not in a zoomed state (browser zoom should be 100%)

Mobile file handling varies by device:
• iOS - Files typically save to the Files app or prompt to share
• Android - Check your Downloads folder or the browser's download manager

Some browsers require enabling download permissions.

Device access requires explicit permission:
• Accept the permission prompt when it appears
• If you denied it, go to browser settings to re-enable
• Some older mobile browsers have limited API support
• Make sure you're using HTTPS

Touch responsiveness issues:
• Close other apps to free up resources
• Make sure your screen is clean
• Restart your browser
• Check if your device is in power-saving mode (can affect performance)
• Try a different browser

Some tools have reduced functionality on mobile due to browser limitations. If a specific tool doesn't work:
• Try a different mobile browser
• Check if the tool documentation mentions mobile limitations
• Use a desktop or laptop for complex operations
