Performance Max Asset Rules Keep Pushing Image Kit Workflows

Google's current Performance Max documentation continues to point advertisers toward a fuller asset set rather than a single hero creative.

That matters directly to Image Kit, because the tool's value rises when asset preparation depends on repeated ratio exports, safe-area discipline, and pre-upload QA instead of one-off resizing.

What Google is requiring

According to Google Ads Help, advertisers should prepare multiple image formats for Performance Max:

• Horizontal 1.91:1 assets for broad placement coverage.
• Square 1:1 assets because they are required and heavily reused.
• Vertical 4:5 assets for stronger mobile inventory coverage.
• JPG and PNG are accepted.
• File size can go up to 5 MB.
• The important subject matter should stay inside the center 80 percent safe area.
• Google recommends at least one image without text or graphic overlays for each aspect ratio.

Google also recommends monitoring asset performance after launch rather than assuming the first export set is final.

Why it matters for Image Kit

For Productokit, the implication is practical. Image Kit should be optimized for:

• repeated aspect-ratio exports,
• compression without softening text edges,
• safe-area checks,
• quick QA before upload.

The secondary implication concerns AI Detector. Teams using generated visuals may want an additional review step before those files become paid media assets.

Product takeaway

This is not a general advertising trend piece. It is a workflow update that changes how Productokit should support asset preparation, creative validation, and final QA for advertisers shipping into Performance Max.
