Choosing between two JPEG exports at 80 KB should not be a guessing game. Live Image Battle at vspic.com/image-battle is a free browser tool that compresses Image A and Image B to the same target kilobyte size using canvas binary search (within ±5 KB), then scores which file kept more visual detail. The winner is declared automatically from SSIM-style pixel comparison — no manual voting. You see compressed size, reduction percentage, quality score out of 100, and quality share percentage for each side.
Use it when comparing WebP vs JPG exports, testing Lightroom or Photoshop presets, validating CDN transforms, or picking which asset to ship for social cards, hero banners, and app thumbnails. Set target KB between 10 and 500 to match real platform limits. Pair with compress image for single-file workflows, compress image to target KB for exact caps, and image health score for a full single-image audit.
Everything runs locally — JPG, PNG, and WEBP only on this page. Click New Battle to reset and try another pair. Share results with your team in one click. No signup, no watermark, no server upload.
