PNG InspectoRoaster: PNG Checker for DPI, Transparency & Print on Demand

Check any PNG before you sell or print it: real DPI and print size, fake transparency, ghost pixels, DTG halo risk and CMYK colors.

Analyzes, grades, and certifies print-ready PNGs for print-on-demand sellers and digital shops. No mercy, no filter, no bad file slipping through. Ruthless PNG quality checker. We roast your file before your customer roasts you in a review. Fair warning: this extension does not sugarcoat anything. If your PNG has a dirty background, embarrassing resolution, or crooked margins, we'll say so. Straight to your face, with sharp humor and zero patience for excuses. It's not cruelty — it's the wake-up call your file needs before a customer leaves it in a 1-star review instead. We figure laughing at your own mess is cheaper than losing the sale over it. Behind the sarcasm, there's real engineering: actual resolution, print DPI, ghost pixels hiding in that "transparent" background, colors that exist on your screen but will never exist in real ink, white halo on DTG prints — all the stuff nobody catches with the naked eye. We catch it, measure it, and don't pretend we didn't see it. 🛍️ If you SELL digital art, clipart, or POD designs Upload your file, pick the preset that matches where you're selling — each one calibrated to that platform's real technical requirements, not a generic rule of thumb — and get a real score, not a vague "looks fine." Pass our test and you can generate a Publication Card with a verification seal, QR code, ready-to-paste listing copy, and an authenticity code any buyer can check for themselves — without just taking your word for it. What this saves you: refunds over unreadable files, one-star reviews about "the print came out blurry," and the embarrassment of finding out only after the customer already complained. 🛒 If you BUY digital art, clipart, or POD designs Before you pay for a file, you deserve to know whether it actually works for what you're making with it — a shirt, a sticker, a banner, a poster, a design element. We test that instantly, right in your browser, and tell you straight up whether the file is "Electronic Trash" or a "Commercial Masterpiece" (yes, those are real category names — we told you we don't sugarcoat). And if the seller already added a verification seal to their listing, you can scan it and check the real technical data before you even click buy. What this saves you: paying for blurry clipart you thought was HD, or finding out after printing that your "t-shirt design" was actually an Instagram screenshot. What we check, no complaints ✓ Real resolution and print size at 300 DPI ✓ Ghost pixels / loose noise hiding in a "transparent" background ✓ Margins and framing ✓ Semi-transparent edges that cause white halo on DTG/DTF prints ✓ Colors that look great on screen but print washed out (outside CMYK gamut) ✓ Aspect ratio and compatibility with your chosen platform Your image never leaves your browser 100% local processing — the extension never sends your artwork to any server, ever. No account, no login, no ads. Available in 10 languages. Go ahead. Drop your PNG in and see if it holds up. If it's genuinely good, you'll walk away with the seal and a well-earned ego boost. If it's not... well, at least you'll find out laughing, not after a 1-star review.
