Auto Fix for rejected HTML5 banners
Drop a rejected banner ZIP into the Banner Validator and press Run Auto Fix. It repairs the technical faults that can be repaired safely, runs the validator again on the repaired ZIP with the same rules and shows you the result, free. With Pro, you download the repaired ZIP. Everything happens in your browser. Nothing is uploaded.
Free: run Auto Fix and see the result, checked again with the same rules. Pro: download the repaired ZIP.
What Auto Fix repairs
Auto Fix repairs these faults and nothing else. You see every change it would make before you download anything.
- Missing or miscased clickTag. A missing clickTag is added where the rules you validate against require one, and a miscased one, such as clickTAG or ClickTag, is renamed so every reference matches.
- Missing ad.size meta tag. Added to the primary HTML file with the width and height of the banner.
- ZIP over the size limit. The images inside the ZIP are recompressed to bring the package under the platform limit, such as 600 KB for Google Ads.
- macOS junk files. The
__MACOSXfolders and.DS_Storefiles a Mac adds when it zips a folder are removed. - Libraries loaded from a CDN. A library loaded from a host the platform does not allow is pointed to the copy the platform accepts, where that swap is safe. Anything else becomes a manual step.
- Backup image for canvas banners. A static JPG of a canvas banner, such as an Adobe Animate export, at the size of the banner and under 150 KB.
- GIF and image banners. A GIF over 150 KB or looping past 30 seconds is rebuilt to fit both limits, and a JPG or PNG banner is recompressed under the weight limit. A whole campaign can be repaired at once with Fix all in Campaign Preflight.
What stays manual
Some problems need a person or a design tool, not a script. Auto Fix lists them as manual steps, each with the free tool that handles it.
-
Files still over the limit after Auto Fix. Auto Fix never scales below a safe point. The Banner Compressor gives you full control over quality and scale for every image and GIF.
-
A landing URL written into the code, or a custom exit. Replace it with a clickTag in the clickTag Editor, or generate the exit code in the clickTag Generator.
-
Wrong dimensions, or a size the platform does not take. Export the banner again from your design tool. The banner sizes page lists the common sizes with a starter kit for each.
-
No primary HTML file, too many files or a file type the platform rejects. Export again from the authoring tool, then run the new ZIP through the Banner Validator.
-
A video or an image for social placements. Auto Fix works on HTML5 banner ZIPs. Check social files in the Ad Spec Checker and the Safe Zone Checker.
How it works
- Drop the ZIP.
Open the Banner Validator, choose Google Ads, Campaign Manager 360 or DV360, and drop the rejected ZIP.
- Read the plan.
When a banner fails, Auto Fix shows the exact list of changes it would make, and the steps it leaves to you.
- Repair and check again.
Auto Fix applies the changes in your browser and runs the validator again on the repaired ZIP, with the same rules. You see before and after, every change and what is left, for free.
- Download.
With Pro, download the repaired ZIP and upload it to the platform.
Your banner never leaves your browser
Auto Fix opens, repairs and checks the ZIP inside this browser tab, with the same JavaScript engine as the validator. The file is not uploaded, not to AdCheckLab and not anywhere else, so Auto Fix suits banners under NDA and campaigns that have not launched yet.
The only network request Pro makes is the account check: whether your signed in account has an active plan, at most once an hour. No file, file name or report is ever part of it.
Free result, Pro download
Auto Fix is part of AdCheckLab Pro, not a separate purchase. Prices are in US dollars, and sales tax or VAT is added at checkout where it applies.

Passing the validator is not approval
Auto Fix repairs technical faults and checks the result against the validator rules for Google Ads, CM360 or DV360. Platforms also review the creative, its claims and the landing page, so the final approval is theirs. Open the repaired banner in the validator preview before you upload it.
Questions
Does Auto Fix change how my banner looks?
It changes code, packaging and image compression, not the layout or the artwork. Recompression can soften an image slightly, so look at the repaired banner in the validator preview before you upload it.
Which ad platforms does it cover?
Google Ads, Campaign Manager 360 and DV360. Auto Fix follows the rules of the environment you choose in the validator, so a repair for Google Ads is checked against the Google Ads limits, such as 600 KB per ZIP.
What if Auto Fix cannot repair everything?
It repairs what it can and lists the rest as manual steps, each with a link to the free tool that handles it. You see the result, and what is left, before you decide on Pro.
Can I see what it would change without paying?
Yes. Free visitors get the full validator report and the exact list of changes, and can run Auto Fix on their own banner to see the result checked again: before and after, every change, and what is still left. Only downloading the repaired file needs Pro.
Is my banner uploaded anywhere?
No. The ZIP is opened, repaired and checked inside your browser. AdCheckLab has no server that receives files.
What does Pro cost?
$9 a month or $79 a year, with every Pro feature included. Dodo Payments, the merchant of record, takes the payment and handles the invoice and sales tax or VAT.
Prefer to fix it by hand?
The free tools handle each fault one at a time, without leaving your browser.
