Should I send my product catalog as one collage image or as a PDF?
If you have 12 products or fewer and want the customer to take them in at a glance inside the chat, send one collage: it opens instantly as a picture and needs no other app. If you have more, or the customer needs to zoom in on details, a PDF with one image per page is clearer, because every product gets a full page at its original resolution.
What the customer actually sees
A collage is one image that shows up right in the chat, and that is its big advantage: nothing to download or open. But the phone shrinks the whole image to the screen width, so the more products you include, the smaller each one's share of the screen until the customer pinches to zoom.
12 products in 4 columns, a 2000 width, a 10 gap, 0 margin and a 1:1 cell shape: the output is 2000 × 1499, with each product in a cell of about 493 × 493.
On a phone each product takes roughly a quarter of the screen width. Build the same collage at 1080 wide and each cell is just 263 × 263, far less detail when zoomed in.
In a PDF each image is its own page, so the customer flips through and sees each product filling the screen. The cost is that the file has to be opened, and its size is close to the sum of the photos, since the conversion tool does not compress them.
A quick rule for choosing
- Collage: a fast look at a small range, such as the colors of one product or this week's offers, or a reply to a customer who asked what you have.
- Collage: when it is enough for the customer to point at an item and you handle the details in the chat.
- PDF: more than 12 products, since the collage maker takes no more per image, while Images to PDF takes up to 20 images.
- PDF: when the customer needs to see fabric, a pattern or a label clearly, or will print the catalog or forward it to someone else.
The best of both: collages inside a PDF
If your catalog has 30 products in several categories, make one collage per category, for example abayas in one image, shawls in another and accessories in a third, then put those images into a single PDF with a page per category. The customer gets a tidy catalog, and every page stays a quick visual summary.
- In the Image collage maker maker build the first category's collage with a suitable column count and download it as JPEG.
- Press “Reset” and repeat for each category, keeping the same settings so the pages look consistent.
- Open the images to PDF tool, add the collages in category order, pick a page size and download the file.
What neither approach gives you
The collage maker does not write names or prices on the photos, and the PDF tool does not add text to pages. If you want prices inside the catalog itself, add them to the photos before combining, or send the price list as a tidy text message keyed to product positions. And remember that a heavy PDF can be slow to arrive on a weak connection, so compress large photos before converting them.
Common questions
Which opens faster for the customer?
The collage, because it is one image shown inside the chat. A PDF has to be downloaded and opened in a viewer.
Do photos lose quality in the PDF?
JPEG photos are embedded as they are, without re-encoding, in most cases. A collage saved as JPEG is written at quality 92.
Are my photos uploaded by either tool?
No, both run inside your browser.
