How to Make a Photo Collage Online (Free, Without Uploading Your Photos)

Short answer: open Imgovo’s Collage Maker, add two to four photos, pick a layout, set the size, gap and background, and download the result. Everything happens in your browser, so your photos are not uploaded.

What the Collage Maker can do

The tool is built for simple, clean collages of up to four photos, not for scrapbook-style designs with stickers.

Setting	Options
Layouts	2 side by side, 2 stacked, 3 in a row, 1 big + 2 small, 2×2 grid
Ready-made sizes	News portal 900 × 600, two photos 16:9, social post 4:5
Aspect ratios	Layout default, 1:1, 3:2, 2:3, 4:3, 3:4, 4:5, 16:9, 9:16 or custom
Custom size	200 to 8000 px per side
Gap between photos	10 px by default
Outer margin	0 px by default
Background	A colour, or transparent for PNG and WebP
Output	JPG, PNG, WebP or AVIF

Each layout needs a specific number of photos, and the tool accepts two to four in total.

Step by step

1. Open the Collage Maker and add your photos. JPG, PNG, WebP, HEIC, TIFF and more work as input.
2. Choose a layout that matches the number of photos.
3. Choose the size. Use a ready-made size for a news portal image or a social post, or pick an aspect ratio, or enter a custom size.
4. Set the gap between photos and the outer margin.
5. Choose the background colour.
6. Adjust each photo (see below).
7. Choose the format and download.

You can undo and redo changes with the buttons or Ctrl+Z and Ctrl+Shift+Z.

Choose what shows in each cell

A cell is rarely the same shape as the photo, so something has to give. There are two modes:

• Fill (default): the photo covers the whole cell and the overflow is cropped. Drag the photo in the preview to choose the visible area, or use zoom and the horizontal and vertical position sliders. “Reset position” starts over.
• Fit: the whole photo is shown inside the cell, and the leftover space shows the background colour.

Faces and important details are what you should keep in view. Check each cell before you save.

Change the order

The order of the photos decides which one goes in which cell. You can use the arrows on the thumbnails, drag the thumbnails, press “Swap photos” or use “Replace photo” to change one image without redoing the layout.

Which size and format to pick

Where it will be used	Suggestion
Social post	Use the 4:5 ready-made size or check the size cheat sheet
News or blog article	900 × 600 ready-made size, or a custom 3:2
Printing or sharing with others	JPG, a larger custom size within the 8000 px limit
Needs transparent gaps	PNG or WebP with a transparent background
Smallest file for a website	WebP or AVIF

JPG is the safest format for sharing. AVIF often gives smaller files, but some older programs cannot open it. For a comparison, read JPG vs PNG vs WebP vs AVIF.

Avoid soft results

If a small photo is stretched to fill a big cell, the collage will look soft, and the tool warns you when this happens. Use the largest copies of your photos, and do not set the collage size much larger than your photos can fill.

If photos need different crops before they go in, prepare them with Crop Image first.

Privacy

The collage is built using the HTML5 Canvas API in your browser. The files never leave your device.
