Frequently Asked Questions

How many images can I combine into one PDF?

There is no set limit. You can add as many images as your browser can handle. For very large collections (50+ large images) performance depends on your device memory.

Can I change the order of pages?

Yes. After adding your images, drag and drop the thumbnails to reorder them before creating the PDF. The page numbers update automatically.

What image formats are supported?

JPG, JPEG, PNG, WebP, and GIF are supported. Each image becomes one page in the resulting PDF.

Will image quality be affected?

The High quality setting preserves full image quality. Medium and Low settings apply mild compression to reduce the overall PDF file size.

Can I mix portrait and landscape images?

Yes. When using Fit to image page size, each page matches the dimensions of its source image. For fixed sizes like A4, images are scaled to fit while keeping their aspect ratio.

Converting Images to PDF

Converting images to PDF preserves exact visual appearance and creates a single portable file that looks identical on any device. Common uses include combining multiple receipt photos into one expense report, creating photo albums, submitting scanned documents, and preparing portfolios for print or email. Page order in the output PDF matches the order images are added. JPEG images are embedded directly into the PDF. PNG images with transparency will have transparent areas converted to white because PDF does not natively support alpha transparency in all viewers. Output file size is roughly the sum of input image sizes plus a small PDF structure overhead. To reduce output size further, compress your images first before converting. Files are processed entirely in your browser - images are never uploaded to any server.

How Does the Image to PDF Converter Work?

This converter accepts several image formats and normalises them into one document. JPG data can be embedded directly because PDF shares its compression method, but formats such as PNG are handled differently: transparency is flattened against a white background and the pixel data is re-encoded into a stream PDF can carry. Each image becomes one page, sized either to the image itself or to a standard paper size, and the tool writes a single page tree covering the whole set.

The result is one file with pages in the order you arranged them. The image and stream object types that make multi format input possible are defined in the published PDF 32000-1 specification.

When Should You Use the Image to PDF Converter?

Use it when you have several images, especially in mixed formats, that belong together as one document. Assembling a set of scanned receipts, combining screenshots into a single report, or turning a batch of photographed pages into one readable file.

If every source file is a JPG photograph, the dedicated JPG to PDF converter is marginally better, since it embeds the original data without touching it. Choose this tool when the batch includes PNG, screenshots or transparency.
