Why combine photos into one?
Posting several separate photos makes people swipe through them, but a single combined image gets the whole story across in one scroll or one thumbnail. For a product comparison you can put the photos side by side so they can be compared at a glance, and content with an order, like a review or product details, reads naturally when stacked vertically. Travel photos or album covers that should show many moods at once suit a grid collage. What matters most is deciding first how many photos to arrange and in what shape.
The four layouts compared
- Side by side: scales the photos to the same height and joins them in a row. Good for product comparisons, color comparisons and process shots (step 1 → 2 → 3) in one line.
- Stacked vertically: scales the photos to the same width and stacks them into one tall image. Suits product pages, long explanations and content read by scrolling. Common product-page widths like 860px and 1000px are available as presets.
- 2×2 grid: fills 4 square cells with photos. Good for a short, balanced collage.
- 3×3 grid: fills 9 square cells with photos. Good for an album feel or showing many scenes at once.
Step by step
- Upload 2 to 9 photos to the Photo Collage Maker.
- Choose the layout that fits your purpose from the four above.
- Use the up and down buttons on each photo in the list to set the order. This step matters most for side-by-side and vertical layouts, where order carries meaning.
- Set the gap (px) and background color. Use a gap of 0 for photos that touch, or about 10–20px for clear separation.
- Add a corner radius for a softer look if you like.
- Choose the file format and quality, check the result size (px, KB) and download.
Tips for order and gap
When joining photos side by side or vertically, the order has a big effect on how the message comes across. Arranging product photos as "problem → solution → in use" reads naturally, while a shuffled order is confusing. If you don't like the order you uploaded in, just change it with the up and down buttons. The gap sets the collage's mood. With no gap (0px) the photos look like one continuous image; a small gap (10–20px) separates each photo and brings out the collage feel. In a grid, a gap that's too narrow feels cramped and one that's too wide stops it looking like one piece, so about 8–16px is a safe choice.
Choosing a background color and corner radius
The background color fills the gaps between photos and any grid cells without a photo. White or a very light gray suits bright photos, while black or deep navy works well for dark tones or a moody feel. If you have a brand color, using it as the background adds consistency. Slightly rounded corners (8–16px) soften the edges and match card-style social media layouts, while square corners (0px) fit places that need a formal look, like print or official documents.
Recommended settings by use
| Use | Recommended layout | Notes |
|---|---|---|
| Product comparison (2–4 items) | Side by side | Compare at the same height |
| Naver Smart Store product page (Korea) | Stacked vertically (860px) | Naver's official recommended width |
| Travel photo set | 2×2 or 3×3 grid | Suits Instagram posts and album covers |
| How-to steps 1, 2, 3 | Side by side or stacked | Arrange so the order is clear |
Good vs. bad examples
- Good: Photos taken from the same angle and distance, joined side by side for a fair comparison.
- Bad: Each photo has different brightness and angle, so the comparison looks unfair.
- Good: A vertical product-page image unified at an 860px width.
- Bad: Uneven widths because each original has a different size (vertical stacking matches the width automatically, so this one is solved for you).
Common mistakes
- Leaving the photos in upload order so the flow feels off.
- Uploading 5 or more photos to a 2×2 grid and not noticing that some aren't included.
- Setting a gap of 0 with a bold background color, which creates an odd border (with a gap of 0 the background barely shows, but it can peek through when you use a corner radius).
- A vertical image so long that it hits the upload size limit. In that case, split it into sections before uploading.
If a very tall vertical image like a product page ends up larger than the platform's upload limit, splitting it into sections and uploading them separately is the safe way.
Checklist
- Did you choose the right layout (side by side, vertical, grid) for the purpose?
- Is the photo order arranged to match the flow of your content?
- Do the gap, background color and corner radius fit the overall feel?
- Is the file size within the upload limit of the platform?
FAQ
Can I combine photos with different aspect ratios?
Yes. Side-by-side and vertical layouts keep each photo's ratio and only match one side (height or width), so different ratios still join naturally. Grid layouts crop each photo to its cell, so choose photos with the important content in the middle.
How many photos can I combine?
From 2 up to 9 at once. A 2×2 grid fills up to 4 cells and a 3×3 grid up to 9; with fewer photos the remaining cells stay empty in the background color.
What if the file is too large?
Switch the file format to JPG or WebP and lower the quality from 90% to about 75%. If a vertical image has become too long for the platform's upload limit, splitting it into sections is another option.
Should I join photos side by side or vertically?
Side by side is natural for comparing photos or showing them all on one screen; vertical suits content with an order (how-tos, before and after, product details).
