Upscale by Sticker Mule is a free AI image upscaler: enlarges images up to 8x while automatically enhancing colors and reducing blur, creating new pixel detail rather than just stretching the original.
Completely free, no subscription or paid tiers. Limits: 5 images/day, max 5MB file size, max 3,000x3,000px input.
Anyone needing occasional (up to 5/day), genuinely free image upscaling for illustrations or photos without a subscription commitment.
The daily cap (5 images) and input size limit (3,000x3,000px, 5MB) rule this out for bulk or very-high-resolution upscaling jobs: fine for occasional single-image use, not a batch workflow.
Unblur and enlarge your images for free.
