Frequently Asked Questions

Yes, FileCraft Pro is completely free to use. All our tools are available without any cost, registration, or hidden fees.

There are no premium tiers, no feature limitations, and no watermarks on your files. We support the service through non-intrusive advertising.

No, FileCraft Pro requires no registration or account creation. Simply open any tool and start using it immediately. We don't collect personal information or require email signups.

FileCraft Pro works on all modern web browsers, including:

• Google Chrome (recommended)
• Mozilla Firefox
• Microsoft Edge
• Safari (macOS and iOS)
• Opera

Our tools work on desktop computers, tablets, and smartphones. For the best experience, we recommend using the latest version of your browser.

Absolutely. Your files never leave your device.

Unlike most online converters that upload your files to remote servers, FileCraft Pro processes everything directly in your web browser using JavaScript. This means:

• We never see your files
• We never store your files
• We never have access to your data
• Your files cannot be intercepted during transfer (because there is no transfer)

This approach makes FileCraft Pro ideal for sensitive documents, confidential business files, and personal photos.

When you use a FileCraft Pro tool:

1. You select a file from your device
2. Your browser reads the file into memory
3. JavaScript code processes the file entirely within your browser
4. The result is generated locally
5. You download the result directly from your browser's memory

At no point is your file sent to any server. You can verify this by using browser developer tools (Network tab) or by disconnecting from the internet after the page loads—the tools will still work!

We collect minimal, anonymous analytics data to improve our service:

• Page views and tool usage statistics (which tools are popular)
• General device/browser information
• Anonymous error reports to fix bugs

We never collect:

• Your files or file contents
• Personal information
• Names, emails, or contact details

For complete details, please see our Privacy Policy.

We support a wide range of formats. The specific formats vary by tool:

Image Formats:

• JPG/JPEG, PNG, GIF, WebP, BMP, TIFF
• HEIC/HEIF (iPhone photos)
• SVG (for certain tools)

Document Formats:

• PDF (merge, split, rotate, convert)

Data Formats:

• JSON, CSV, XML
• Base64 encoded data

Text Formats:

• Plain text, Markdown, HTML

Since processing happens in your browser, the limits depend on your device's available memory (RAM). General guidelines:

• Most devices: Can handle files up to 50-100MB without issues
• Powerful computers: May handle files up to 200-500MB
• Mobile devices: Best results with files under 30-50MB

For very large files (high-resolution photos, multi-page PDFs), you may experience slower processing. If your browser becomes unresponsive, try using a device with more RAM or processing the files in smaller batches.

Browser-based processing uses your device's resources. Processing speed depends on:

• File size: Larger files take longer to process
• Device performance: Newer devices with more RAM process faster
• Browser: Chrome generally offers the best performance
• Other applications: Close unused tabs and programs to free up memory

Tips for faster processing:

• Close other browser tabs
• Use a desktop/laptop instead of mobile for large files
• Process files in smaller batches
• Use Google Chrome for best performance

Once a tool page has fully loaded, most of our tools will continue to work even if you lose internet connection. The processing happens entirely in your browser.

However, you need an internet connection to:

• Initially load the tool page
• Load external resources (fonts, etc.)

For reliable offline use, consider using browser "Save Page" functionality or dedicated desktop software.

To maintain quality when resizing:

• Downscaling (making smaller): Always safe. Our tools use high-quality resampling algorithms.
• Upscaling (making larger): Can cause pixelation. Try to avoid enlarging images more than 150-200% of original size.
• Maintain aspect ratio: Enable "Lock aspect ratio" to prevent distortion.
• Use PNG for crisp graphics: PNG preserves sharp edges better than JPG.

Try our Image Resizer tool for precise control over dimensions and quality.

Password-protected PDFs cannot be merged directly. You'll need to:

1. Remove the password protection first (you need to know the password)
2. Save unprotected copies of the PDFs
3. Then merge the unprotected versions

This is a security feature—it prevents unauthorized manipulation of protected documents.

JPG (JPEG):

• Best for photographs and complex images
• Smaller file sizes
• Lossy compression (some quality loss)
• No transparency support

PNG:

• Best for graphics, logos, screenshots
• Larger file sizes
• Lossless compression (no quality loss)
• Supports transparency

For a detailed comparison, read our guide: JPG vs PNG: Which Should You Use?

Try these troubleshooting steps:

1. Refresh the page: Press Ctrl+F5 (Windows) or Cmd+Shift+R (Mac) for a hard refresh
2. Try a different browser: Chrome typically works best
3. Clear browser cache: Old cached files can cause issues
4. Disable browser extensions: Some ad blockers or privacy extensions can interfere
5. Check file format: Make sure your file is in a supported format
6. Try a smaller file: Large files may exceed browser memory limits

If problems persist, please contact us with details about your browser, device, and the issue.

If downloads aren't starting:

• Check popup blocker: Some browsers block automatic downloads. Look for a blocked download notification.
• Check downloads folder: The file may have downloaded to an unexpected location.
• Allow downloads from this site: Your browser may be blocking downloads from unfamiliar sites.
• Try right-clicking: Some browsers require manual "Save As" for certain downloads.

Common causes and solutions:

• Colors look different: This can happen when converting between formats (especially JPG to PNG or vice versa). Some color information may be interpreted differently.
• Image looks blurry: You may be enlarging beyond the original resolution. Try to keep upscaling under 200%.
• Transparency is gone: If you converted to JPG, transparency is replaced with white. Use PNG to preserve transparency.
• PDF pages are in wrong order: Drag and drop to reorder before merging.
