How to Create a Photo Collage

  1. Add your photos - Click the file picker or drag and drop images directly into the photo area. You can add as many photos as you like.
  2. Arrange your photos - Drag a thumbnail onto another thumbnail to swap it into that position. This works with a mouse or your finger on touch screens. The first photo appears in the top-left position, flowing left to right, top to bottom. Or tap Shuffle to randomize the order.
  3. Choose a layout - Grid arranges photos in rows and columns. Horizontal Strip places all photos side by side. Vertical Strip stacks them top to bottom. Freeform lets you place each photo anywhere on the canvas by hand.
  4. Fine-tune in Freeform mode - Tap or click a photo to select it, then drag it anywhere. Use the round handle above the photo to rotate it and the corner handle to resize it. The toolbar buttons let you layer photos in front of or behind each other (Forward and Backward), return the selected photo to its starting spot (Reset), or restore the whole arrangement (Reset All). To remove a photo, tap the × on its thumbnail.
  5. Adjust settings - Choose whether photos Fill their cells (cropped to cover) or Fit inside them (whole photo visible). The Style section holds the background color or gradient, photo borders, corner roundness, shadows, and the outer border. The Canvas Size section holds dimensions and social media presets.
  6. Download - Choose JPEG for smaller files or PNG for lossless quality, then download your collage.

Social Media Size Guide

Different platforms have different ideal image sizes. Here are the most common formats and when to use them:

IG Grid (1080×1440, 3:4) displays uncropped everywhere on Instagram since the profile grid switched from squares to taller 3:4 previews. IG Feed (1080×1350, 4:5) is Meta's recommended portrait feed size, and it doubles as the best all-purpose portrait format for Facebook, LinkedIn, and Threads; on Instagram it gets slightly trimmed top and bottom on the profile grid. Story / TikTok (1080×1920, 9:16) is the full-screen vertical format shared by Instagram Stories and Reels, TikTok, Snapchat, Facebook Stories, and YouTube Shorts, making it the single most reusable size for a collage today. One tip for this format: keep faces and anything important away from the very top and bottom (roughly the outer 250 pixels of each), since platform interfaces like usernames and reply fields overlay those areas. A larger outer border handles this nicely. Square (1080×1080, 1:1) works across nearly every platform, though portrait sizes now get more screen space in most feeds. Pinterest Pin (1000×1500, 2:3) is the tall format that performs best on Pinterest's grid. HD Landscape (1920×1080, 16:9) suits desktop wallpapers, YouTube thumbnails, and presentation slides.

A note on Facebook: photo posts there display best at square or 4:5 portrait, so use those presets. The 1200×628 size often quoted for Facebook is the thumbnail format for shared links, not the display size for photos you upload.

Tips for Great Collages

Use photos with similar color tones or themes for a cohesive look. When mixing portrait and landscape photos, the grid layout handles them best by cropping each to fill its cell evenly. A small gap (2 to 6 pixels) between photos gives a clean, modern look, while zero gap makes the photos read as one continuous mosaic. For print projects, use larger canvas dimensions (3000+ pixels) and PNG format to preserve quality.

Photo borders are applied to every photo at once, which keeps the whole collage consistent. A white border of 8 to 15 pixels over a colored or dark background recreates the classic printed-photo look, while a border in the same color as the background acts like extra visual spacing. In Freeform mode, a white border plus a slight rotation gives each photo a polaroid-style, hand-placed feel. The outer border extends the background around the edge of the collage: on a white background it gives a clean gallery-mat look, and matching the outer border thickness to the gap setting produces even spacing everywhere, including around the edges.

Freeform mode is great for scrapbook-style layouts: overlap photos at slight angles for a casual, hand-placed feel, or rotate a few photos a couple of degrees to break up a rigid arrangement. Photos can hang off the canvas edges for a full-bleed look - anything outside the canvas is simply cropped in the final download.

FAQ

How many photos can I add? There's no hard limit - you can add as many photos as you want. However, with more than about 20 photos in a grid, each cell becomes quite small. For best results, 2 to 12 photos works well.
Can I reorder photos after adding them? Yes - drag a thumbnail onto another thumbnail to move it into that spot, using either a mouse or your finger on a touch screen. The collage updates automatically when you change the order. In Freeform mode, the thumbnail order also controls layering: later photos appear on top.
Can I add a border? Yes. The Photo Border slider draws a border around each individual photo in the Border Color. The Outer Border slider adds extra space around the entire collage in the background color, so the whole area behind and around your photos stays one consistent surface controlled by the Background picker. The outer border applies to the Grid and Strip layouts; in Freeform mode photos can be placed right up to the canvas edge for a full-bleed look. Slide either back to 0 to turn it off.
Can I round the photo corners? Yes - the Corners slider rounds every photo at once, from a subtle softening at low values up to pill shapes at the top of the range. It combines with the photo border, which curves along with the corner, and it works in Freeform mode too. The background color shows through the rounded-off areas.
How does Freeform mode work? Select Freeform from the Layout menu, then tap or click any photo on the canvas to select it. Drag to move it, use the round handle to rotate (it snaps at 90° angles), and drag the corner square to resize. On touch screens you can also pinch with two fingers to resize and rotate the selected photo in one gesture. Bring Forward and Send Backward control which photos overlap which.
What are the pink lines that appear while dragging? Those are smart alignment guides. When the photo you're moving lines up with the canvas center, a canvas edge, or the center or edge of another photo, a pink guide line appears and the photo gently snaps into alignment. The same idea applies while resizing: when your photo's width or height matches another photo's, both get a pink outline and snap to exactly equal size - making uniform layouts easy.
What happens if my photos are different sizes? In Fill mode (the default), each photo is cropped to fill its cell using a "cover" fit, similar to how CSS background-size: cover works - centered and scaled so no empty space appears, though some edges may be trimmed. Switch Photo Fit to "Fit" to show every photo in full with no cropping; the background shows around photos that don't match their cell's shape.
Can I use a gradient background? Yes - set Gradient to Vertical, Horizontal, Diagonal, or Radial and a second color picker appears. The linear options blend from the first color to the second across the canvas, while Radial places the first color at the center and fades to the second color at the edges, a soft vignette effect that draws the eye toward your photos. The gradient covers the whole canvas, including the gaps and outer border.
How do shadows work? The Shadow slider adds a soft drop shadow under every photo. Small values give a subtle lift off the background; larger values look best combined with a wider gap so the shadow has room to fall. In Freeform mode shadows follow each photo, including rotated ones.
JPEG vs PNG - which should I choose? JPEG produces smaller files and is ideal for photos and social media sharing. PNG is lossless, preserving exact pixel quality - best for print or when you need a transparent background.
Are my photos uploaded anywhere? No - everything is processed entirely in your browser. Your photos never leave your device.
Can I use this on mobile? Yes - the tool works on phones and tablets. Tap the file picker to select photos from your camera roll, and all the same layout, border, and download options are available.
