Frequently Asked Questions

What image formats are supported?

Currently, the converter supports JPG/JPEG and PNG image formats. These are the most common image formats and cover the vast majority of use cases. If you have images in other formats, convert them to JPG or PNG first using an image editing tool.

Will the PDF maintain the original image quality?

Yes, absolutely. The converter preserves the original resolution and quality of your images. The images are embedded in the PDF at full resolution without compression or quality loss, ensuring your PDF looks as good as the original images.

Can I mix different image sizes in one PDF?

Yes, you can combine images of different sizes and aspect ratios. Each image becomes a page sized to match that image's dimensions. The PDF will have variable page sizes, with each page optimized for its image.

Is there a limit on the number of images?

There's no strict limit, but performance depends on your browser's memory. For best results, we recommend batches of 50-100 images at a time. Very large image collections should be processed in smaller groups for optimal performance.

Are my images uploaded to a server?

No, never. All image processing and PDF conversion happen entirely in your browser. Your images never leave your device, providing complete privacy and security. No data is stored, collected, or transmitted to any server.

Can I add text or annotations to the images?

This tool focuses on pure image-to-PDF conversion. For adding text, annotations, or editing, use a PDF editor after conversion. The tool preserves images exactly as they are without modifications.

What happens to transparent backgrounds in PNG images?

Transparent areas in PNG images will appear as white in the PDF. PDF doesn't natively support transparency in the same way as PNG, so transparent pixels are rendered with a white background.

How large can the resulting PDF be?

The PDF size depends on the number and resolution of images. High-resolution images create larger PDFs. For example, 10 photos at 3MB each will create roughly a 30MB PDF. Consider resizing very large images if file size is a concern.

Did You Know?

•Resize large images before conversion if you need smaller PDF file sizes
•Name your images sequentially (001, 002, 003) for easy ordering
•Use JPG format for photos and PNG for screenshots or graphics with text
•The number indicator on each thumbnail helps track the page order
