AI image → 300 DPI Etsy-ready in 8 seconds.

The only browser-based upscaler engineered for ChatGPT Image 2.0 junk journal sellers. One drop. One click. One ZIP. Zero subscription, zero upload, zero "credits left" panic.

Etsy rejects digital downloads under 300 DPI. ChatGPT Image 2.0 outputs at 72 DPI by default — about a quarter of what you need. Free upscalers either hallucinate AI texture (waxy ephemera, melted paper edges) or rate-limit you to 5 images/day with a watermark on top. Paid services charge $0.20 per image and require uploading your kits to their servers. This tool runs 100% in your browser, batch-processes folders of AI outputs, applies a junk-journal-tuned enhance pass (Lanczos upscale + unsharp mask + aged-paper warmth + contrast curve), and exports PNG/JPEG with embedded 300 DPI metadata Etsy validates against. Lifetime access. Unlimited images. Zero ongoing fees.

Why This Exists

3 problems every FE buyer hits when shipping to Etsy.

The kits look gorgeous on screen. Then you try to list them on Etsy and discover the rules.

Problem 1: Etsy rejects 72 DPI ChatGPT Image 2.0 (and every AI image tool) outputs at 72 DPI by default. Etsy's printable-product policy requires 300 DPI minimum. Your gorgeous AI kit gets flagged "low resolution" and removed from listings within 48 hours of upload.
Problem 2: Free tools wreck the texture Generic upscalers (Topaz, Upscayl, free web tools) are tuned for photos. They smooth out the aged-paper grain, sharpen handwriting into pixel mush, and saturate the cottagecore palette into HDR mode. Your buyer notices on print day and demands a refund.
Problem 3: Paid services rate-limit + upload Subscription upscalers charge $20-$30/mo, cap at 100 images, and require you to upload your private AI kits to their servers — which their TOS often gives them rights over. Your competitive advantage gets fed back into their training data.

🔧 How It Works

Three clicks. One ZIP.

JC Upscaler step 1 — drop AI images into the input section ↑ drop or click ↑
01

Drop AI images

Drag-drop one image, or a whole folder. PNG, JPG, WebP — direct from ChatGPT, Midjourney, DALL-E, or Flux.

JC Upscaler step 2 — pick output size with Etsy presets, always 300 DPI ↑ pick a preset · output always 300 DPI ↑
02

Pick output size

One-click presets for Etsy: 8.5×11" letter, 12×12" square, 5×7" card, 4×6" tag. Output: always 300 DPI.

JC Upscaler step 3 — click the red Upscale & Download button to save ↑ one click · single PNG or batch ZIP ↑
03

Click upscale

Single image: PNG saved instantly. Batch: ZIP with all files at 300 DPI, named with original filenames + suffix.

📦 What's Inside

6 features. All tuned for junk journal.

01

Multi-Step Lanczos Upscale

Progressive 2× upscaling stages produce cleaner output than one-shot interpolation. Preserves aged-paper grain instead of smoothing it into mush.

02

Unsharp Mask Sharpening

Edge-aware sharpening with preserve-text mode — boosts ephemera detail and handwriting clarity without creating halos around high-contrast lines.

03

Aged-Paper Warmth Curve

Subtle midtone-biased warmth (R+, B-) replicates the cream tone real junk journal collectors want. Calibrated for ChatGPT Image 2.0's default palette.

04

S-Curve Contrast Boost

Punches up midtone contrast without crushing shadows or blowing out highlights. The exact range that makes printed kits "pop" without looking HDR.

05

Embedded 300 DPI Metadata

PNG pHYs chunk + JPEG JFIF density bytes injected so Etsy's automated print-quality check reads "300 DPI" correctly. Not just resampled — properly tagged.

06

Batch + ZIP Export

Drop 20 images, click upscale, get a ZIP with all 20 at 300 DPI. Original filenames preserved with _300dpi suffix. No naming chaos.

🔬 Honest Tech Specs

What it is. What it isn't.

No "AI-powered" hype. This is a browser-native enhance pipeline — Lanczos resampling + unsharp mask + tone curves — calibrated specifically for AI-generated junk journal aesthetic. Honest about scope:

✓

What it does

Upscales 2-8× cleanly · sharpens text legibly · warms aged-paper tones · embeds 300 DPI metadata · batches folders into ZIP · runs 100% offline after first load.

✗

What it doesn't do

Generate new pixels with AI hallucination · rescue blurry source images · convert raster to vector · remove backgrounds · re-color the kit. Garbage in = garbage out, just at 300 DPI.

⚡

Speed & size limits

~3-8 seconds per image at 8.5×11 / 300 DPI on a modern laptop. Tested up to 50 images per batch. No server, no rate limit — just your browser's RAM.

FAQ

Honest answers, no fluff.

No. Those use neural networks to hallucinate new detail — which often wrecks AI-generated junk journal art (smooths the grain, melts the ephemera, sharpens "fake" handwriting into pixel artifacts). The JC Upscaler uses traditional Lanczos resampling + targeted enhance passes calibrated for the cottagecore aesthetic. It preserves your AI's intent instead of overriding it.

Private access link delivered to your inbox at checkout. Bookmark it, runs in any modern browser (Chrome, Firefox, Safari, Edge). 100% client-side — once the page loads, everything happens in your browser, no uploads, no API calls. No installation, no signup, no SaaS account, no monthly fee. Lifetime access, yours forever.

100% private. The tool runs entirely in your browser — nothing uploads to any server. Your AI kits never leave your computer. We literally can't see what you process even if we wanted to.

Yes. The tool embeds PNG pHYs chunk (the metadata Etsy reads for PNG DPI) and JPEG JFIF density bytes (for JPEG DPI). Tested across multiple Etsy listings — automated print-quality check passes. Most other free upscalers skip this step, which is why their output gets flagged.

Yes. The enhance presets are tuned for cottagecore aesthetic, but you can dial them down to "Soft" or zero for general-purpose upscaling. Other use cases that work well: planner stickers, digital art prints, vintage ephemera, scrapbook elements, KDP coloring page interiors.

Limited only by your browser's RAM. Tested with 50-image batches at 8.5×11 / 300 DPI (each output ~10MB) — runs cleanly on any laptop with 8GB RAM. For very large batches (100+), process in 50-image chunks.

Mac: yes (Chrome, Safari, Firefox — full desktop). iPad: yes for small batches. iPhone/Android: works but cramped UI; not recommended for production. Best on a real laptop or desktop.

Yes. The tool is a single HTML file delivered at checkout. When new features ship (additional presets, faster algorithms, new export formats), buyers get the new version free via email. No subscription, no "premium tier" upsell.

30-day refund, full $67 back, no follow-up email asking why. Anexazrose@gmail.com. We'd rather have an honest "not for me" than a frustrated buyer.
