A good photo collage maker online gives you creative control — not rigid templates. Pixora’s layer workflow lets you build collages like a designer: each photo on its own movable layer, blend modes for artistic merges, shapes for borders, text for captions. This guide covers three styles — grid, blended montage, and scrapbook.

Set up your collage canvas

Every collage starts with Canvas Size: decide the final shape first — square (1:1) for social, 4:5 portrait for feeds, 16:9 for wallpapers. Bigger is better here; you can always downsize at export, but you cannot recover resolution. A 2000–3000 px canvas gives comfortable room for 4–9 photos.

Fill the background layer with intention: a solid color via the paint bucket (G), a subtle gradient, or one photo blurred heavily as an atmospheric backdrop. Then bring in photos one by one — each arrives as its own layer, ready to move (V), scale via Image Size on that layer’s content, and reorder in the stack. Name layers (“beach”, “portrait”) as you go; collages accumulate layers fast.

Style 1: the clean grid

The grid is the most-shared collage style because it is effortlessly tidy. Plan your grid (2×2, 3×3), then crop (C) each photo to the cell shape before placing — uniform cells are what make grids look professional. Leave consistent gutters: set your background layer to a color (white, black, or a brand color) and let it show between photos as even spacing.

Precision trick: place the first photo, duplicate its layer as a positioning reference, and align subsequent photos against it before deleting the reference. Even 10 px of misalignment breaks the grid illusion, so zoom in and nudge carefully. Export grids as JPEG at 85% — photographic content compresses beautifully (see our compression guide).

Style 2: the blended montage

For artistic collages, let photos melt into each other with blend modes and the eraser. Overlap two photos on separate layers, then erase the top layer with a large soft brush at 30–50% opacity along the overlap — the fade between images looks seamless. Try the screen blend mode for dreamy light merges or multiply for moody dark blends.

The double-exposure look is one blend away: place a portrait over a landscape, set the portrait layer to screen, lower opacity to taste, and erase hard edges. Add a unifying noise filter at low opacity over everything so merged photos share the same grain — the secret step that makes composites believable. Our layered images guide explores blend modes in full depth.

Style 3: scrapbook with borders and captions

Scrapbook collages embrace overlap and personality. Rotate individual photo layers slightly (a few degrees, via rotate) for the casual pinned-photo feel. Build borders with the shapes tool (U): draw a white rectangle slightly larger than each photo on the layer beneath it for instant polaroid frames. Vary the tilt and overlap — controlled chaos reads as charming, uniform chaos reads as messy, so keep one anchor photo straight.

Captions complete it: small text labels (T) with dates or jokes, rotated to match their photo’s tilt. Finish with a light vignette over the whole canvas to unify the composition, then export PNG if text sharpness matters or JPEG for photo-heavy pieces (our format guide helps you choose).
