Image Collage Maker: free online, fast and secure
A collage lets you share many photos as one image: before-and-after shots, product variants, trip highlights or event memories. This free collage maker arranges 2 to 16 photos automatically into a tidy layout.
Pick an auto grid, a single row or column, or a fixed number of columns. Choose square, 4:3, 3:4 or 16:9 cells, adjust the spacing and background colour, and download a high-resolution JPG or PNG.

Why use ConvertKaro Image Collage Maker? Free, fast and secure

Fast results
No waiting for uploads to finish. The work happens on your device the moment you add a file, which makes it noticeably faster than server-based tools.
Secure and private
Your files never leave your device. ConvertKaro does not upload, store or look at your documents and photos, which makes it safe for ID cards, bank statements and private pictures.
No signup, no watermark
You do not need to sign up or log in, and your output is clean, without any logo or branding.

Good to know
Two numbers describe every digital image: its dimensions in pixels (for example 1600×1200) and its file size in KB or MB. Dimensions decide how sharp the picture looks; file size decides how fast it loads and whether a form accepts it. Format matters too: JPG is best for photos, PNG for graphics and transparency, WEBP and AVIF for websites. Image Collage Maker lets you control these things without Photoshop, and because everything runs locally, you can experiment as many times as you like without waiting for uploads.

How Image Collage Maker keeps your photos and images private
Most online converters upload your file to their server, process it there and send it back. That costs time, uses your data pack and means a copy of your file sits on someone else’s computer. Image Collage Maker works differently: the page loads the tool into your browser, and your photos and images are processed by your own phone or computer. The file never travels over the internet, so it cannot be leaked, stored or misused.
Using Image Collage Maker on your phone
Image Collage Maker is designed for small screens. Buttons are large, options are simple, and downloads save directly to your phone storage. On iPhone, downloaded files appear in the Files app under Downloads; on Android they go to the Downloads folder.
