Blank Image Generator
🖼️ 100% Private: Generated entirely in your browser—no uploads.
Create dummy images for testing with exact dimensions and format, and optionally target an approximate file size.
If a target is set, the generator auto-tunes compression and may add harmless padding to reach within ±5%.

Note: Preview is the actual encoded image. Some viewers may downscale display but downloaded file keeps full dimensions.
- ℹ️ File size vs. dimensions: size depends on format, quality, and image complexity. Noise/Checker compress less than solid colors.
- 🎯 Targeting MB: we auto-tune JPEG/WEBP quality and (optionally) pad trailing bytes if still under target.
- 🔒 Privacy: Everything runs locally; nothing is uploaded.
