Perceptual mass
Scores how heavy each mark feels — so thin outlines and dense fills land at the same visual weight, not the same box size.
Get visually balanced logos in seconds
Balance images and logo clouds by visual weight using perceptual science — not simple bounding boxes. Free in your browser, no signup.

PNG, JPG, WebP, GIF — up to 10 more in this batch
Free tier: full Smart Image Balancer preview for up to 10 images. Advanced tuning and export require Pro.
Under the hood
Built on perceptual science — not bounding boxes
ImageBalancer measures what your eye actually sees: mass, light, edges, and empty space. Here's what that unlocks.
Optical centering
Places logos by visual center of mass, with subtle overshoot past the bounding box on pointed or curved edges so shapes feel correctly sized.
Intelligent padding
Trims uneven margins and applies consistent breathing room across every tile in the batch.
Background cleanup
Removes white padding and solid backdrops so mass and bounds are measured on the mark itself — not leftover canvas.
Envelope & luminance sensing
Reads how sparse a shape is inside its envelope, and weights darker pixels more than light ones — outlines and solids are treated differently.
Advanced dial-in controls
Tune mass, envelope, luminance, and more for the whole batch — or override any setting per image when one logo needs special treatment.

Frequently asked questions
Do I need an account to use ImageBalancer?
No. The free tier works instantly in your browser with no login. Sign in only if you want premium features.
Are my images uploaded to a server?
No. All processing happens locally in your browser. Your images never leave your device.
What is perceptual visual weight balancing?
Instead of fitting images to the same bounding box, we analyze pixel density and alpha data to calculate how heavy each asset looks visually, then scale them so they appear equal in weight.
What file formats are supported?
PNG, JPG, WebP, and GIF. Output is PNG with optional transparent or white backgrounds.
How many images can I process?
Free users can preview up to 10 images per batch with the full Smart Image Balancer. Pro users can process up to 35 and download the results.
Can I download results on the free tier?
The free tier includes the full balancing preview so you can see exactly how your grid will look. Download, ZIP export, and advanced engine tuning require Pro.
What's the difference between monthly and lifetime?
Both include the same Pro features. Monthly is $9/mo and can be cancelled anytime. Lifetime is a one-time $59 payment for permanent Pro access.
