Frequently Asked Questions

Yes, absolutely! QuickImageHub is 100% free to use with no hidden fees, subscriptions, or premium tiers. All seven of our tools—Image Converter, Image to PDF, PDF to Image, Merge PDF, Compress PDF, Split PDF, and Protect PDF—are completely free and will remain free forever. We're committed to providing accessible, high-quality image and PDF tools to everyone without charging a single cent. Our goal is to make file processing simple, fast, and cost-free for all users worldwide.

No, your files are never uploaded to our servers. This is one of the core principles of QuickImageHub. All image conversions, PDF operations, compressions, merging, splitting, and password protection happen entirely in your web browser using JavaScript. When you upload a file, it stays on your device and is processed locally by your browser's computing power.

This approach provides several key privacy benefits:

• Your files never leave your device, so there's zero risk of interception or unauthorized access during transmission
• We have no access to your files, which means we can't accidentally leak, lose, or misuse your data
• You can use QuickImageHub offline (once the page loads) since processing doesn't require server communication
• No file storage means no data retention policies to worry about—your files exist only on your device

For complete details about our privacy practices, please read our Privacy Policy.

QuickImageHub supports the most popular and widely-used image formats:

• JPG/JPEG: The most common format for photos and general images
• PNG: Best for images requiring transparency or lossless quality
• WEBP: Modern format offering superior compression and quality
• HEIC/HEIF: Apple's format used by iPhones and iPads (iOS 11+)

You can freely convert between any of these formats. For example, convert iPhone HEIC photos to JPG for wider compatibility, or convert JPG to WEBP for smaller file sizes with minimal quality loss. Our tools handle format detection automatically—just upload your images and select your desired output format.

QuickImageHub offers generous limits designed to handle most personal and professional use cases:

• Maximum file size: 100MB per individual file
• Maximum batch size: Up to 50 files per batch operation

These limits apply across all our tools. You can convert up to 50 images at once, merge up to 50 PDFs into a single document, extract pages from PDFs up to 100MB in size, and more. For most users, these limits are more than sufficient for everyday tasks like preparing presentation materials, organizing photo albums, managing documents, and creating portfolios.

If you regularly work with files exceeding these limits, please contact us to discuss your specific needs.

Yes, you're welcome to use QuickImageHub for both personal and commercial purposes! There are no restrictions on business usage. Whether you're a freelance designer converting client images, a real estate agent creating property PDFs, a marketing professional optimizing web graphics, or a small business owner managing documents, you can use our tools freely without any licensing fees or commercial restrictions.

For enterprise teams or organizations requiring custom features, integrations, or support, please contact us to discuss tailored solutions.

QuickImageHub is supported by non-intrusive advertising through Google AdSense. We display relevant, privacy-respecting ads that help cover our hosting costs and development expenses while keeping all our tools completely free for you. We carefully balance ad placement to ensure they don't interfere with your workflow or distract from the tools you're using.

We will never charge users for our core features, sell your data, or introduce mandatory subscriptions. Our commitment is to provide free, accessible tools funded by ethical advertising that respects your experience and privacy.

No, absolutely not! QuickImageHub requires zero registration. There are no accounts, no email verification, no passwords to remember, and no profiles to manage. Simply visit our website, select the tool you need, upload your files, and start processing immediately. This approach respects your time, reduces friction, and eliminates concerns about email spam or data collection. We believe great tools should be instantly accessible to everyone without barriers.

Your data is extremely secure because it never leaves your device. Since all processing happens in your browser, there's no transmission of files over the internet to remote servers where they could potentially be intercepted, logged, or compromised. This client-side architecture provides the highest level of security possible.

Additionally:

• Our website is served over HTTPS, ensuring all communications are encrypted
• We don't use cookies to track your file processing activities
• Password protection for PDFs is performed locally—your passwords never leave your browser
• Once you close your browser tab or download your files, all temporary data is automatically cleared

For sensitive documents requiring password protection, you can use our Protect PDF tool knowing that your passwords are processed entirely on your device and never transmitted to any server.

Yes! QuickImageHub has full support for Apple's HEIC (High Efficiency Image Container) and HEIF (High Efficiency Image Format) formats, which are used by iPhones and iPads running iOS 11 or later. These formats offer better compression than JPG while maintaining similar quality, but they're not universally compatible with all devices and software.

You can easily convert your iPhone HEIC photos to more widely-supported formats like JPG, PNG, or WEBP. This is particularly useful when sharing photos with Android users, uploading to websites that don't support HEIC, or importing into older photo editing software. Our converter maintains image quality while ensuring broad compatibility across platforms and devices.

Processing speed depends on several factors including your device's computing power, file sizes, number of files in the batch, and the complexity of the operation. However, because all processing happens locally in your browser without network delays, QuickImageHub is typically very fast:

• Image conversions: Usually complete in seconds, even for large batches
• PDF operations: Vary by file size; small PDFs process in seconds, larger ones may take 10-30 seconds
• HEIC conversion: Slightly slower than standard conversions due to format complexity, but still typically under 10 seconds per image

Modern devices with faster processors will see quicker processing times. Because there's no uploading or downloading from servers, you'll often find QuickImageHub faster than server-based alternatives that require file transfers.

Yes! QuickImageHub is fully responsive and works seamlessly on smartphones, tablets, and desktop computers. We've carefully designed our interface to provide an excellent experience across all screen sizes and devices.

Merging PDFs with QuickImageHub is simple and straightforward:

1. Navigate to the Merge PDF tab on our homepage
2. Click "Upload PDFs" or drag and drop your PDF files into the upload area
3. Once uploaded, you'll see thumbnail previews of all your PDFs with page counts
4. Drag and drop the thumbnails to reorder them in your desired sequence
5. Click "Merge PDFs" to combine all documents into a single PDF
6. Download the merged PDF file to your device

You can merge up to 50 PDFs at once, and each PDF can be up to 100MB in size. The entire process happens in your browser, so your files remain private and secure. This tool is perfect for combining contracts, reports, receipts, or any other PDF documents into a single, easy-to-share file.

Our Split PDF tool makes it easy to extract specific pages:

1. Go to the Split PDF tab
2. Upload the PDF you want to split (up to 50MB)
3. You'll see thumbnail previews of all pages with page numbers
4. Select pages by clicking thumbnails or entering page ranges (e.g., "1-5, 8, 11-13")
5. Use "Select All" or "Deselect All" for quick selection management
6. Choose to download selected pages as a single merged PDF or as individual PDFs in a ZIP file

This tool is ideal for extracting specific chapters from ebooks, separating relevant pages from long reports, or creating custom documents from existing PDFs. Everything processes locally in your browser for maximum privacy.

Our Compress PDF tool offers three compression levels to balance file size reduction with quality preservation:

• Low: Minimal compression that preserves the highest quality; ideal when quality is paramount
• Medium: Balanced compression that reduces file size while maintaining good quality; recommended for most use cases
• High: Maximum compression for smallest file size; best for documents where minor quality loss is acceptable

Compression works by optimizing the PDF structure, removing redundant data, and compressing embedded images. The "before and after" comparison shows exactly how much space you've saved. This is especially useful for reducing large PDF files for email attachments, web uploads, or storage optimization.

For text-heavy documents, even high compression typically has minimal visible impact on quality. For image-heavy PDFs, medium compression usually provides the best balance.

Our Protect PDF tool provides an easy way to add password protection to your PDF documents:

1. Navigate to the Protect PDF tab
2. Select "Protect PDF" mode (if you want to add a password) or "Unlock PDF" mode (if you want to remove password protection)
3. Upload your PDF file
4. Enter your desired password and confirm it
5. Click "Protect PDF" to encrypt the document
6. Download the password-protected PDF

IMPORTANT: All password processing happens entirely in your browser—your passwords are never sent to our servers or stored anywhere. The encryption uses industry-standard AES-128 encryption provided by the pdf-lib library.

Note: This tool provides basic password protection suitable for personal documents. For highly sensitive or confidential information requiring enterprise-grade security, we recommend using professional PDF software with advanced encryption options.
