How to use Merge JPG Images
Choose the images in the order you want them, pick top to bottom or side by side and the gap, choose JPG or PNG, then press Merge images and download the picture.
How the images are sized
Top to bottom gives every image the same width, and side by side gives every image the same height, so the edges line up. Each picture keeps its shape; smaller ones are enlarged to match the largest. Very large results are scaled down to stay under 40 megapixels so phones can open them.
JPG or PNG?
JPG keeps photos small enough to send in chats and email. PNG is lossless and keeps screenshots and text sharp, at a larger file size.
How it works
Images are scaled to the same width (or height) and drawn onto one canvas
Examples
- Worked example
Join two screenshots side by side into one image to share in a chat.
Limitations and assumptions
Up to 20 images. Very large results are scaled down to stay under 40 megapixels.
