The Numbers
What you get back in time and money.
Save $15,750 and reclaim 450 designer-hours per year.
450 hours back. That's 11 full work-weeks per designer redirected from production drudgery to creative work.
Same output, 1/10 the cost. Every campaign drops from $350 of labor to $35.
How it works
Up to 4 text fields (Headline, Subhead, CTA, Body) and up to 3 images (Hero, Alternate, Logo).
All 21 standard ad sizes build instantly using your active Smart Template, or choose a single ad, a few, or all 21 before populating.
Tweak any size by hand, then save the file as a new Smart Template to reuse for the next campaign.
Note: Instant Ad Sizer doesn't resize finished artwork after the fact. It populates all 21 standard sizes from your text and image inputs using a Smart Template. Build a template once, reuse it forever, or build an unlimited library of templates for different campaigns and clients. You're in control.
Features
Online ad-sizing platforms typically solve about 60% of the problem. Instant Ad Sizer solves around 90%, so you finish in minutes, not hours.
Compare
Other tools make professional designers rebuild and relearn. IAS adds power to the workflow you already own.
Need HTML5 banner output, an API for engineering pipelines, or a browser-based shared workspace? IAS isn’t the right fit, Creatopy, Bannerbear, and Canva are stronger choices for those jobs. IAS does one thing: it supercharges the Illustrator workflow professional designers already use. Like adding a supercharger to a V8 instead of rebuilding the whole car for slightly more power.
Sizes
Built to match the briefs your agency or client already sends.

A campaign that takes 10+ hours manually drops to under 1 hour with Smart-fit. If you ship 50 campaigns a year, that’s 500 hours of work down to 50 — about 450 hours saved per designer, every year.
