About the Image Duplicator
What is an image duplicator?
An image duplicator takes one picture and repeats it across a grid, so you can turn a single tile into a full pattern, a sprite sheet, or a page of identical copies ready to print. Instead of copying and pasting by hand, you tell the tool how many rows and columns you want and it lines everything up with pixel precision. The best part here: it works with animated GIFs too. Tile a looping GIF and you get a brand-new animated GIF where every copy plays in sync.
Everything happens right in your browser. Your image is never uploaded to a server, the preview updates live as you tweak the settings, and the finished file is written on your own machine — so even private artwork stays private.
How to Use This Tool
- Add an image. Click to upload, drag and drop, or paste from your clipboard. GIFs, PNGs, JPGs and WebP all work — or hit Sample image / Sample GIF to try it instantly.
- Set the grid. Choose how many columns and rows to repeat, and add spacing between the tiles if you want gaps.
- Shape the pattern. Scale the source up or down, rotate it, mirror alternate rows or columns for a seamless flip, or offset every other row for a brick-style layout.
- Pick a background. Keep it transparent (great for PNG and GIF) or fill the gaps with any color.
- Export. Download as PNG, JPG, WebP, or an animated GIF, or copy the result straight to your clipboard.
What makes it powerful
- Animated GIF support: A real GIF decoder and encoder run in the browser, so tiling a GIF gives you an animated GIF back, not a frozen still.
- Pattern controls: Mirror alternate tiles or offset rows like brickwork to build seamless, repeating textures.
- Scale & rotate: Shrink the source to pack in more tiles, or spin it in 90° steps for varied layouts.
- Flexible export: PNG for quality, JPG for size, WebP for the modern web, or GIF to keep motion — plus one-click copy.
- Private & instant: No uploads, no sign-up, no watermark; the live preview shows exactly what you will get.
Common Use Cases
- Seamless patterns: Turn a small tile into a repeating background for a website, print, or wallpaper.
- Sprite sheets: Lay out multiple copies of a sprite in a neat grid for games or animation.
- Contact sheets: Fit several copies of a photo onto one page for stickers or printing.
- Fun with GIFs: Multiply a meme or reaction GIF into a hypnotic grid that still loops.

Frequently Asked Questions
Can I really tile an animated GIF?
Yes. The tool decodes every frame of your GIF, tiles each one, and re-encodes a fresh animated GIF, so the whole grid plays together. Just keep the export format set to GIF. Other formats will save a single still frame instead.
Does duplicating lower the quality?
No. Each copy is drawn from your original pixels. If you leave the scale at 100%, the tiles are identical to the source. Scaling down is only to help you fit large grids without creating an enormous file.
Can I make a transparent pattern?
Yes. Turn on Transparent background and export as PNG or GIF, both of which support transparency. JPG has no transparency, so it fills the gaps with white.
Is there a size limit?
Browsers cap how large a single image can be (around 16,000 pixels per side), and animated GIFs use more memory because every frame is held at once. If an output gets too big, the tool warns you and suggests lowering the scale or grid size.
Are my images uploaded anywhere?
No. All decoding, tiling and encoding happen locally in your browser with JavaScript. Your files never leave your device, so your images stay completely private.
