Make a photo collage in your browser

What the collage maker is for

The collage maker in Lightframes arranges several photos on one image in a clean grid, with even gaps between them. Use it for a trip recap, a before-and-after, a product set, a story post with a handful of moments, or a multi-slide Instagram post where each slide is its own little grid.

It lives inside the photo editor, so the photos in your collage are the developed versions, not the raw originals. Edit a set with a preset, fix a few spots, and the collage uses all of it without exporting each photo first.

How it works and what happens to your photos

The collage is built and exported entirely in your browser; your photos never leave your device. When you export, Lightframes develops each photo with its edits at the resolution its cell actually needs, draws every slide at full size and saves it as a JPEG. Cell edges are snapped to whole pixels, so neighbouring photos never leave a thin seam.

There’s no account and no upload, and once the app is loaded, collage also works offline.

Sizes

All slides in a collage share one size, set under Size:

Aspect	Name	Pixels
9:16	Story	1080 × 1920
3:4	Tall	1080 × 1440
4:5	Portrait (default)	1080 × 1350
1:1	Square	1080 × 1080
4:3	Classic	1440 × 1080
3:2	Photo	1620 × 1080
16:9	Widescreen	1920 × 1080
1.91:1	Landscape	1080 × 566

Layouts and controls

Under Layout, choose how many Photos the current slide holds, from 1 to 9, and then one of the layouts for that number. There are 40 in total, for example:

• 2 photos: Side by side, Stacked, Wide left, Tall top.
• 3 photos: Big left, Big right, Big top, Big bottom, Three columns, Three rows, Wide middle.
• 4 photos: Grid, Big left/right/top/bottom, Four columns, Four rows, Mosaic.
• 5 photos: Two over three, Three over two, Pinwheel and more.
• 6 to 9 photos: column and row grids, Big corner, Big middle, a 3 × 3 Grid and others.

Other controls:

• Border: turn it on or off, set the Width (0.5 to 6% of the slide width, 1.5% by default), pick a colour from the swatches or any custom colour, and choose whether the Outer edge is framed too.
• Photo: select a cell to set its Zoom (100 to 400%), Reset framing or Remove the photo.
• Fill empty: drops photos that aren’t in the collage yet into the empty cells.
• Slides: add a slide, duplicate it, move it left or right, or delete it, up to 20 slides.

If you open more than nine photos, Lightframes starts you off with grids of four per slide; with nine or fewer, it puts them all on one slide.

Tips

• Pick the size first. Changing the aspect later changes every cell’s shape, so framing may need a touch-up.
• Use thin borders for a modern look, or turn borders off for a tight mosaic. White or cream borders give a classic print look; black suits night and city shots.
• Mix orientations sensibly. Put portrait photos in tall cells and landscapes in wide ones to avoid heavy crops.
• Give the first slide a strong lead photo in multi-slide posts, since it’s the one shown in the feed.
• Want one image running across slides? That’s the Instagram carousel maker, in the same mode.

Limitations

Collages are exported as JPEG only, at the fixed sizes above. There’s no text, stickers or free-form placement: photos sit in layout cells (the carousel mode allows free placement). Your photos and edits are restored after a reload, but the collage layout itself is not, so export before you close the tab. For other questions, see the FAQ or open the editor.
