Question 1

Question 2

Can I rearrange the image order before creating the PDF?

Accepted Answer

Yes, after uploading you can drag and drop images to arrange them in any order. The PDF pages will match your arrangement. This is useful for creating photo albums, portfolios, or organized document collections where sequence matters.

Question 3

What image formats are supported?

Accepted Answer

We support all common image formats including JPG/JPEG, PNG, GIF, BMP, WebP, and TIFF. You can mix different formats in the same PDF. Each image is converted to a PDF page while maintaining its original quality and appearance.

Question 4

Is there a limit on how many images I can combine?

Accepted Answer

The free tool supports up to 50 images in a single PDF. This covers most typical use cases like photo albums, scanned document collections, and portfolios. For larger collections, ChatSlide AI offers unlimited image combining capabilities.

Question 5

What size will the PDF pages be?

Accepted Answer

By default, images are fitted to standard page sizes while maintaining aspect ratio. A horizontal image gets a landscape page; a vertical image gets a portrait page. ChatSlide AI offers options to set custom page sizes, fit all images to a uniform size, or let each image determine its page dimensions.

Question 6

Will image quality be preserved in the PDF?

Accepted Answer

Yes, images are embedded in the PDF at their original resolution and quality. We don't compress or reduce image quality during conversion. If your images are high-resolution, the PDF will maintain that quality for printing or zooming.

Question 7

Can I add margins or borders around images?

Accepted Answer

The basic conversion places images to fill the page. ChatSlide AI offers margin control, border options, and page layout customization. You can add white borders, center images with padding, or create specific layouts for professional portfolios.

Question 8

What is the maximum total file size?

Accepted Answer

The combined total of all images can be up to 100MB. Individual images can be up to 50MB each. Large collections may take longer to process but will complete successfully. The resulting PDF size depends on the number and size of input images.

Question 9

How long does conversion take?

Accepted Answer

Most conversions complete in 10-45 seconds depending on the number and size of images. Larger collections take longer as each image is processed and embedded. The process is fully automated.

Question 10

Can I create a PDF with multiple images per page?

Accepted Answer

The basic tool places one image per page. ChatSlide AI offers multi-up layouts like 2-up, 4-up, or grid arrangements where multiple images appear on each page. This is useful for creating contact sheets, proof sheets, or compact image collections.
