Creative Preflight Checklist: How to Check Your Ad Before Launch

Tadvio Creative Preflight is built for that moment. Upload a finished static creative, review four groups of checks, see a readiness score with clear severity levels, and identify which additional campaign sizes still need adaptation. It is free to use, consumes no Tadvio credits, and requires an account to run the check.

In design and production, “preflight” means checking an asset before it is handed off or published. For static advertising, that means validating practical production details on the finished file rather than judging the creative idea itself.

Tadvio Creative Preflight focuses on four areas: File health, Layout safety, Readability, and Size fit. It is designed to answer questions such as: Is this file large enough? Is important content too close to the edge? Can the text be read confidently from the flattened creative? Which common placements can this exact shape serve?

The point of preflight is not to redesign the ad. It is to catch production risks while they are still cheap to fix. A designer may have finished the composition, but the launch team still needs to know whether the file is technically healthy, whether the content sits safely within the frame, whether the text is readable enough to review, and whether the asset covers the campaign shapes that are actually needed.

• Catch resolution, file-weight, transparency, edge-spacing, readability, and size-fit issues before handoff.
• Separate “Must fix” items from “Should improve” suggestions instead of presenting every finding as equally urgent.
• See when a check could not be verified instead of treating missing information as a pass.
• Understand campaign coverage from the current creative shape and identify missing sizes for adaptation.
• Move a finished creative directly into AI Resizer when additional campaign sizes are needed.

1. File health

File health is measured locally from the uploaded image. Creative Preflight reads the file’s dimensions, file weight, format, and transparency without uploading the original creative for those checks.

• Resolution: very small creatives can be flagged as Must fix; lower-resolution assets can be marked Should improve.
• File weight: files over 8 MB are flagged as Should improve.
• Transparency: any alpha transparency is reported as Should improve so the production team can review whether it is intentional.
• Format: PNG, JPG, and WebP are reported in the technical details. Format itself is not treated as a pass/fail issue.

Creative Preflight accepts PNG, JPG, and WebP files up to 20 MB.

2. Layout safety

Layout safety looks at how close measured content sits to the frame and whether detected text falls inside Tadvio’s recommended safe area for the creative shape.

• Edge margin: content touching or nearly touching the outer edge can be flagged as Should improve.
• Safe area: detected text outside the recommended safe area can be flagged as Must fix.
• When text cannot be read confidently, the product can still surface measured “text-like” or busy regions and mark the text-specific part of the check as not checked instead of pretending it passed.

3. Readability

Readability is evaluated only when Tadvio’s text reading step can verify the text regions in the flattened creative. The product measures the size of detected text, estimates contrast against the pixels behind it, and checks overall text density.

• Text size: very small text relative to the creative can be marked Must fix or Should improve.
• Estimated contrast: strong, measurable contrast can pass; weaker results can be flagged. Photo or gradient backgrounds are treated more cautiously and can require a human look rather than producing a high-severity failure.
• Text density: if detected text covers more than 40% of the creative, it is marked Should improve.
• Arabic and mixed Arabic/English creatives are supported in the text reading step, including right-to-left reading.

4. Size fit

Size fit compares the creative’s aspect ratio and resolution with known advertising placements. It is a shape-and-resolution check, not a policy check.

• Size fits: the aspect ratio matches within tolerance and the resolution meets the placement minimum.
• Too small: the shape is correct, but the resolution is below the placement minimum.
• Needs resize: the creative uses a different aspect ratio and cannot serve that placement as-is.

Tadvio uses one neutral cross-platform safe-area recommendation per common aspect ratio. These guides are intentionally not presented as official platform-published safe zones. Their job is to provide a conservative production reference for keeping important content away from risky edges.

Curated guides are available for 9:16, 4:5, 1:1, 16:9, and 1.91:1. The 9:16 guide is the strictest because vertical placements commonly have more interface pressure near the top and bottom. When a creative uses another shape, Creative Preflight derives a conservative minimum safe area from that aspect ratio so the layout-safety check can still run.

In the product, curated guides are labelled “Tadvio Recommended Safe Area.” Derived guides are labelled “minimum safe area for this shape.” Neither label should be read as certified platform compliance.

The current size-fit library represents 11 common static-ad placements across Meta, Instagram, TikTok, YouTube, Google Display, LinkedIn, X, and Snapchat. Examples include square and tall feeds, 9:16 stories or in-feed placements, 16:9 video-frame placements for static creative use, and 1.91:1 landscape placements.

Platform filters let the user re-score the same measurements for Auto detect, Meta, Instagram, TikTok, YouTube, Google Display, or LinkedIn. Switching the filter does not require a new upload or a new server analysis call.

Creative Preflight does not send every uploaded image for text analysis. It first performs local pixel analysis to find busy, high-frequency regions that may contain text. If no candidate regions are found, no text-reading request is made.

When a reading step is useful, Tadvio sends a reduced-size raster, capped at 1024 px on the long side. The returned text regions are then checked against the actual pixels: regions without glyph detail are removed, boxes are tightened around real glyphs, and missed text-like regions can be added back as explicitly estimated areas.

If the reading step fails, is temporarily unavailable, returns nothing, or conflicts with the pixel evidence, Creative Preflight does not silently mark readability as passed. Instead, the relevant category is shown as “Not checked” and excluded from the available score. The overlay legend distinguishes “Detected text” from “Text-like area (measured, not read).”

The result is shown as a readiness score out of 100. The four categories — File health, Layout safety, Readability, and Size fit — each contribute up to 25 points when they are fully checkable. Within a checked category, Must fix findings reduce the score more heavily than Should improve findings.

If a category could not be verified, that category is excluded from both the earned and available points, and the overall result becomes “Partial check.” This is intentional: an unavailable check does not inflate the score as if it had passed.

After the quality checks, Creative Preflight shows campaign coverage in two parts. “Current creative fits” lists placements that share the current shape, labelled either Size fits or Too small. “Expand your campaign” lists the distinct shapes the current creative cannot serve as-is.

If additional sizes are needed, “Adapt with AI Resizer” opens a size chooser. Nothing is pre-selected. The user chooses the missing sizes and continues to AI Resizer, where the original full-resolution creative is loaded with exactly those sizes active. Creative Preflight does not calculate the cost and does not generate anything itself; pricing and generation remain entirely inside AI Resizer.

Creative Preflight checks a finished creative. AI Resizer adapts a finished creative into additional sizes. Studio is for building and controlling compositions with editable Tadvio elements — see how the workflow runs end to end. Creative Preflight does not reconstruct a flattened ad into editable layers.

Most of the check happens on the user’s own file in the browser. Dimensions, file weight, transparency, edge margins, and pixel-based contrast measurements are local. The original creative is not uploaded for those checks.

For Tadvio’s text reading step, a reduced-size copy — up to 1024 px on the long side — is sent for analysis. The image bytes are not stored. The resulting text-position data can be kept briefly in a workspace-scoped cache so repeating the same check does not require the same analysis again. Creative Preflight does not save the original creative, the report, or the readiness score.

The original full-resolution file is uploaded only if the user deliberately chooses “Adapt with AI Resizer,” and then it is placed in that user’s private workspace source area for the Resizer workflow.

Yes. Creative Preflight is free to use and consumes no Tadvio credits. An account is required to run a check because the product runs inside an authenticated workspace. There is no user-facing usage quota. If the optional text analysis is temporarily unavailable, the remaining local checks still run and the result clearly shows which part was not checked. Generation in other Tadvio workflows is covered by Tadvio pricing.

• A creative that looks sharp on screen but is too small for its intended placement.
• Text or other important content sitting too close to the outer edge.
• Detected text outside Tadvio’s recommended safe area.
• Very small text that may be difficult to review at delivery size.
• Weak or uncertain contrast in a flattened image.
• A text-heavy composition where text occupies a large share of the canvas.
• A file that is heavier than necessary for handoff.
• A campaign that still needs additional aspect ratios even though the master creative is finished.

Creative Preflight gives designers, marketers, and production teams a fast final check on the file they are actually about to use. It does not replace creative judgment or platform review. It gives the team a clearer production picture: what is healthy, what needs attention, what could not be verified, and which campaign sizes are still missing.
