Why Convert Images to PDF?

Converting images to PDF offers several advantages over sharing raw image files. PDFs are universally supported across all devices and operating systems, ensuring your recipients can view your content without compatibility issues. Unlike individual image files, a PDF keeps multiple images organized in a single, professional document.

PDFs also preserve image quality and layout exactly as you intended. When you share images through messaging apps or email, they often get compressed or resized. A PDF maintains the original quality and arrangement, making it ideal for portfolios, presentations, and official documents.

For printed materials, PDFs provide precise control over page sizing and margins. Whether you're creating a photo book, a document scan collection, or presentation handouts, PDF format ensures consistent, predictable output on any printer.

Tips for Best Results

Use consistent image sizes for a more uniform PDF. Mix sizes work too, but may require adjusting orientation settings.

Choose "Auto" orientation to let each page adapt to its image. Tall images get portrait, wide images get landscape.

Add margins for printing if you plan to print the PDF. "Small" or "Medium" margins ensure content isn't cut off.

Use "Original Size" for art portfolios or when exact image dimensions matter more than standard page sizes.

Frequently Asked Questions

What image formats can I convert to PDF?

We support JPG/JPEG, PNG, and WebP formats. These cover nearly all digital photos and graphics you might have.

How many images can I combine into one PDF?

There's no strict limit, but for best performance, we recommend batches of 50 images or fewer. Very large batches may be slow depending on your device and image sizes.

Can I rearrange the order of images after uploading?

Yes! Simply drag and drop images to reorder them. The order you see is exactly how they'll appear in your final PDF.

Will my images be uploaded to a server?

No. All processing happens locally in your browser. Your images never leave your device, ensuring complete privacy and security.

What's the difference between the orientation options?

'Auto' chooses portrait or landscape based on each image. 'Portrait' forces vertical pages, 'Landscape' forces horizontal. Auto is usually the best choice for mixed content.

Can I add margins to my PDF pages?

Yes! Choose from No Margin (edge-to-edge), Small (0.5 inch), or Medium (1 inch) margins. Margins are helpful if you plan to print the PDF.

Does image quality get reduced when converting to PDF?

No. Images are embedded in the PDF at their original quality. There's no compression or quality loss during the conversion process.

Can I convert HEIC/HEIF images from iPhone?

HEIC format isn't directly supported. Convert HEIC images to JPG or PNG first using your phone's sharing options or another converter, then use this tool.

What's the maximum image file size?

Individual images up to 20MB are recommended for best performance. Very large images may slow down processing depending on your device's memory.

Can I convert scanned document images to PDF?

Absolutely! This is one of the most common use cases. Scan your documents to JPG or PNG, then combine them into a single PDF.
