Fixed-cell PNG export — not a full-resolution stitcher

Pix-8 Image Collage Maker is a photo collage creator that exports a crisp flattened PNG from a client-side canvas — each photo renders in a 360×360 pixel cell with cover crop. Pick vertical strip, horizontal row, two-column grid, 2×2, or 3×3, tune gap and background, preview live, and download. It does not upscale cells, accept custom export dimensions, set print DPI, or preserve each source photo at its native pixel dimensions.

Why export collage PNG on-device?

Server collage tools re-encode your gallery before export. Pix-8 composites locally and flattens to PNG — the practical fit when you need a high-resolution photo collage creator that delivers a sharp, lossless composited file without uploading source photos to a remote service.

Lossless PNG flatten

Export one flattened PNG from the client-side canvas — no server recompression of your composited collage.

Predictable canvas output

Each cell renders at 360×360 pixels; total export dimensions follow your chosen layout preset and gap spacing.

Private client-side render

Photos stay on your device during compositing and export. Pix-8 never receives your files on a server.

How it works

  1. Step 1

    Open Image Collage Maker

    Navigate to Pix-8 in your browser — compositing starts locally with no install or sign-up.

  2. Step 2

    Compose on a client-side canvas

    Upload photos, pick a strip or grid preset, adjust gap and background, and preview the flattened layout live.

  3. Step 3

    Export flattened PNG

    Download or copy one PNG from the canvas — optional EXIF metadata stripping before share.

Frequently asked questions

What resolution does this photo collage creator output?

Pix-8 Image Collage Maker composites each photo into fixed 360×360 pixel cells on a client-side canvas, then exports one flattened PNG. Total export size depends on your layout — for example, a 2×2 grid is roughly 732 pixels wide with default gap spacing; a 3×3 grid is roughly 1,104 pixels wide. Output is lossless PNG from the canvas. The tool does not offer custom export dimensions, DPI settings, or upscaling beyond the built-in cell size.

Will my collage keep the full resolution of each source photo?

Photos are cover-cropped into 360×360 pixel cells — detail beyond what fits each cell is trimmed, not preserved at the source file's native dimensions. Starting with sharp source images still helps within each cell. For a single image at full native resolution, use Pix-8 Resizer separately. Collage Maker does not stitch full-resolution originals into oversized cells or export print-ready DPI metadata.

Does creating a high-resolution collage require uploading photos to a server?

No. Compositing and PNG export run entirely in your browser on a local canvas. Your photos are read from your device and are never transmitted to Pix-8 or any third-party server. Optional EXIF metadata stripping runs on-device before export. The tool offers five strip and grid presets with gap and background controls — not cloud rendering or server-side upscaling.
