Specifications and Requirements

Step-by-Step Guide

1. Open imgresizr.com/gif-maker in any browser — works on desktop and mobile.
2. Upload your images in order — drag multiple files at once or add them one by one. JPG, PNG, and WebP are all supported.
3. Arrange the frame order by dragging thumbnails — the first frame appears first in the animation loop.
4. Set the frame delay (milliseconds between frames) — use 100ms for smooth animation, 500–1000ms for slideshow-style.
5. Set the loop count — enter 0 for infinite loop, or a specific number for limited plays.
6. Preview the GIF in real-time before exporting — adjust frame order or delay as needed.
7. Click Create GIF and then Download — your animated GIF is ready to share or upload anywhere.

Pro Tips

• Upload at 2× the display size where possible — extra pixels buffer against platform compression artefacts
• Always check your profile photo at thumbnail size (40px) — a face that looks fine at full size can become unrecognisable miniaturised
• Use PNG for graphics with text overlays — JPG compression degrades text edges at smaller sizes
• Avoid placing critical content in the outer 10% of any image — platforms may crop or overlay edges
• Back up processed images in cloud storage — losing a batch of correctly sized images means starting over

Common Mistakes to Avoid

• Uploading images that are too small: Stretching a small image to fit a larger dimension reduces quality. Always start with an image at least as large as the target dimensions.
• Using the wrong file format: Using JPG for logos and graphics causes visible compression artefacts around edges. Use PNG for graphics, JPG for photography.
• Ignoring aspect ratio: Forcing an image into incorrect dimensions stretches or squashes it. Always maintain the correct aspect ratio for the platform.
• Over-compressing: Reducing quality too aggressively creates blocky artefacts. Aim for 75–85% JPG quality as a safe balance between file size and visual quality.
