One clean workflow

Your source folder is not a customer-ready product.

Buyers see filenames, extraction steps, missing instructions, and broken files—not the hours you spent designing. PreflightZIP catches that packaging gap before a listing or download goes live.

01

Add the real product files

Choose loose files, a complete folder, or an existing ZIP. Nothing is uploaded for analysis.

02

Review the exact findings

Blockers, warnings, file facts, verification depth, and package limits stay visible before generation.

03

Download the customer pack

Receive up to five Etsy-sized ZIPs, customer instructions, your license, a manifest, and a build receipt.

Checks that name their limits

Useful evidence. Zero fake “perfect” badges.

PreflightZIP tells you whether it read metadata, checked a signature, checked additional structure, or saw only a filename extension.

ZIP integrity + safetyCRC, traversal paths, suspicious expansion, and collisions.
Etsy upload limitsFive-file plan, 20 MB outputs, and compatible filenames.
Format-aware preflightImages, PDF, SVG, fonts, and common embroidery formats.
Customer documentsSTART-HERE, seller-authored license, manifest, and receipt.
Delivery cleanupKnown macOS and Windows metadata stays out of the product.
Private processingCommercial source files stay inside the seller's browser.
PreflightZIP reports evidence—not fake perfection.It does not grant intellectual-property rights, replace physical production tests, promise Etsy acceptance, or guarantee sales.

Questions, answered

Know what happens before you add a file.

Are my product files uploaded anywhere?

No. Auditing, repackaging, hashing, and report generation happen in your browser. PreflightZIP does not receive a server copy of the product files.

Does “ready” guarantee Etsy will accept the listing?

No. It means the reported technical checks found no blocker. Listing content, seller policy, legal rights, and Etsy's final decisions remain outside PreflightZIP.

Why not use a normal ZIP app?

A normal archive app compresses files. PreflightZIP also checks Etsy's delivery constraints, identifies package risks, inspects supported file structures, generates customer documents, and records final fingerprints.

Will it repair every finding automatically?

No. It safely removes known system junk and rebuilds package boundaries. It does not silently modify artwork, fonts, PDFs, embroidery data, or usage rights.

Which devices are supported?

PreflightZIP is designed for current desktop browsers. Large product folders need enough local memory, and physical production files still need testing in the software or machine your buyers use.
