Free online repeat image generator. Tile images, create image patterns, repeat photos in rows and columns. No upload, instant tile preview, download PNG.

What is a Repeat Image Generator?

A repeat image generator (also called an image tiler or tile maker) is an online tool that takes a single image and repeats it in a grid pattern to create a larger, tiled image. You control how many times the image repeats horizontally (columns) and vertically (rows). Unlike desktop software that requires installation and file uploads, this tool runs entirely in your browser using HTML5 Canvas technology. It draws your source image repeatedly across rows and columns to create anything from a simple 2×2 pattern to a dense 10×10 tile grid. The result is a single, downloadable image file perfect for backgrounds, wallpapers, patterns, and textures — all created without ever uploading your original image to a server.

Repeat Image Generator Features

Create beautiful tiled images and repeating patterns with these built-in features.

  • Flexible Grid Tiling

    Choose any grid size from 1×1 up to 10×10 — customize both horizontal (columns) and vertical (rows) repetitions independently.

  • Real-Time Preview

    See your tiled image update instantly as you adjust rows and columns. No waiting for server processing.

  • Multiple Output Formats

    Download as PNG (lossless, ideal for patterns with sharp edges) or JPEG (smaller file size for photos).

  • 100% Client-Side

    All image tiling runs in your browser. Zero server uploads — your images stay completely private.

  • Large Output Support

    Automatically constrains output to 8192px on the longest edge. Choose grid sizes that fit your intended use.

How to Create a Tiled Image

Three easy steps to repeat and tile any image into a pattern.

  1. 1. Upload Your Image

    Drag and drop a JPG, PNG, or WebP image into the upload area, or click to browse files from your device.

  2. 2. Set Rows & Columns

    Use the sliders to choose how many times to repeat the image. Columns control horizontal repeats, rows control vertical repeats.

  3. 3. Download Your Tiled Image

    Click Download PNG or JPG to save your tiled image. The result is a single image file with the pattern repeated in a grid.

Tips for Creating Tiled Images

Best practices for getting perfect tiled results.
  • 01

    Start with Small Images

    Source images of 200-400px width produce manageable tiled outputs. Very large source images with high repeat counts can generate very large files.

  • 02

    Use Seamless Images for Patterns

    For seamless repeating patterns, use images whose edges align — left with right, top with bottom. This prevents visible grid lines in the tiled output.

  • 03

    Match Grid to Aspect Ratio

    For a square final image, use the same number of rows and columns. For a banner, use more columns than rows (e.g., 5×2).

  • 04

    Choose PNG for Sharp Patterns

    Download as PNG for patterns with text, icons, or sharp edges. Use JPG for photo-based tiles to reduce file size.

  • 05

    Preview Before Downloading

    Always check the live preview to ensure the tile pattern looks right before downloading the full-resolution image.

  • 06

    Watch the Output Size

    A 500px source image tiled 8×8 creates a 4000×4000px output. Keep your intended usage resolution in mind when choosing grid sizes.
