About the Collage Maker
Collages exist because some stories take more than one image to tell. A before-and-after pair shows change; a four-photo grid summarizes an event; a side-by-side comparison answers a question more directly than either image alone could. The collage maker is a deliberately small tool: pick a grid, drop in photos, set the spacing, export. No nested templates, no text overlays, no filters — just a fast path from several images to one shareable composition.
The available templates cover the most useful cases. 2×1 places two images side by side, perfect for before-and-after comparisons or paired product shots. 1×2 stacks them vertically, which works well for vertical phone photos and Stories-style layouts. 2×2 is the classic four-photo grid for event recaps or a portfolio snapshot. 3×1 and 1×3 are three-photo strips, useful for sequential storytelling or comparing three options.
Spacing and background color are deceptively important to how a collage reads. Tight spacing with no border feels modern and editorial — the images form a single block. Generous spacing with a colored background gives each photo room to breathe and feels more polished, more like a printed magazine layout. Black backgrounds make colors pop; white backgrounds feel clean and minimal; matching a brand color ties the collage to a larger visual system.
Image fitting in each cell is automatic. Each photo is scaled to fit its cell while preserving its aspect ratio, and the excess is cropped from the edges (a center crop, the safest default). If you want a specific framing within a cell, crop the photo first using the Image Cropper, then drop it into the collage — that way the cell shows exactly what you intended.
The collage renders entirely on a canvas in your browser. The export is a PNG at the resolution of your largest input photo, so collaging 4K source images produces a high-resolution result suitable for printing or large-screen display. There's no upload, no server-side rendering, no third-party watermark. Once you've exported the PNG, you can run it through the compressor for a smaller file, or the format converter to produce a WebP version for the web.

Tips and best practices
Use photos with similar aspect ratios
A grid where every photo is landscape (or every photo is portrait) looks visually balanced. Mixing landscape and portrait inputs in the same cell means more aggressive cropping on the odd one out.
Crop first for tighter compositions
Each cell auto-fits its photo with a center crop. If you want a specific framing — for example, a face placed off-center — crop the source first using the Image Cropper, then drop the result into the collage.
Pick a background that supports the content
Dark photos against a black background fade into each other; the same photos against a white background pop. A 5–10 pixel gap with a neutral background is usually the safest starting point.
Match social media aspect ratios
A 2×2 grid of 1080×1080 photos produces a 2160×2160 collage — perfect after resizing back to 1080×1080 for Instagram. Plan your final dimensions before you start so the export fits the destination.
Compress before posting
Full-resolution PNG collages can be large. Run the export through the compressor (or convert to WebP) before posting to social media or embedding in a blog — you'll save a lot of bandwidth with no visible change.
Technical details
How cell sizing works
Each cell in the grid is allocated equal space (minus the gap) and the photo is scaled to fill that space while preserving its aspect ratio. Excess content is cropped from the center, which is the most predictable default. The output canvas is sized to the largest input dimensions to preserve resolution.
Why PNG and not JPG
PNG output preserves the exact rendered canvas losslessly, which is the right default for a fresh composition. If you need a smaller file for web use, run the PNG through the format converter or the compressor — JPG quality 85 typically shrinks a collage 60–80% with no visible loss.
Working with mixed orientations
If you mix landscape and portrait photos in the same grid, the auto-fit will crop more aggressively on the photos whose aspect ratio doesn't match the cell. To avoid this, pre-crop sources to a common aspect ratio (1:1 is the most forgiving) using the cropper before composing the collage.
Frequently asked questions
Can I use images of different sizes?
Yes. Each cell auto-fits its photo. For the cleanest result, use images with similar aspect ratios — otherwise some cells will crop more aggressively than others.
Can I add text or stickers?
Not in this version. The collage maker focuses on grid layouts. For text overlays, export the collage and add text in a dedicated editor.
What is the output resolution?
The output is sized to fit the largest input dimensions, so combining 4K photos produces a high-resolution collage. The PNG is exported losslessly.
Can I make a custom non-grid layout?
Only the five grid templates are supported. For freeform compositions, export individual photos and arrange them in a dedicated image editor like Figma, Photoshop, or Affinity Designer.
Does it work with portrait phone photos?
Yes. Use a 1×2 or 1×3 vertical layout for vertical phone photos to keep them in their native orientation without cropping.
Can I save the collage as a JPG instead?
The export is PNG. To convert to JPG, run the PNG through the format converter — that gives you the option to also pick a quality level.
Are there any watermarks on the output?
No. The collage is unbranded. We do not add any watermark, logo, or attribution to the exported PNG.
