Free AI Image Upscaler
Upscale textile patterns and designs — plus photos and artwork — 2× or 3× with AI. Real detail — not just bigger pixels. Output up to 16K, no watermarks.
What is AI image upscaling?
AI image upscaling makes a picture bigger and better. Instead of simply stretching pixels — which produces blur, halos, and ringing — our AI analyses the image, understands what it's looking at, and adds real detail that didn't exist before. The result is sharper edges, cleaner textures, and legible type at a size the original couldn't support.
For textile and print work, this matters more than in consumer photography. A 1500×1500 pattern destined for a 30cm repeat at 300 DPI needs to reach 3543×3543 before it's production-ready — you can check the exact target resolution for your run with our Print Calculator. Ordinary upscaling loses weave detail and introduces moiré; our AI preserves motif structure while hitting the resolution you need. If you're working from a scanned swatch with visible halftone or moiré, run it through the AI Texture Remover first for a clean starting point. The upscaler itself is tuned specifically for textile and surface-design work, so fabric weaves and motif edges come through crisp at 4K, 8K, or full 16K print resolution.
Smart Upscale vs AI Enhance
Smart Upscale (what you're using here) is our instant preset-tuned enhancement — the same engine paid Studio users run on the free mode. AI Enhance is a different beast: full Texloom AI that rebuilds detail and fixes blur.

What people use our AI upscaler for
Upscale an image to 4K
Our AI image upscaler turns a standard 1080p image into a 4K (3840×2160) version in one click with the 2× preset — no subscription, no card, no watermark. edge-preserving resampling and edge-aware sharpening keep lines, type, and pattern detail crisp instead of just stretching pixels. If your source is blurry or heavily compressed to begin with, pair it with our AI Image Sharpener first for cleaner 4K output.
Upscale a JPG for free
Drop a JPG straight in — no conversion needed. The upscaler reads JPG/JPEG, PNG, WEBP, and TIFF natively, preserves EXIF orientation on portrait photos, and exports a clean PNG with an alpha channel. Need a different output format instead? Our Format Converter handles PNG → JPG / WEBP / TIFF with quality control.
Upscale a low-resolution image without losing quality
The combination of edge-preserving resampling and edge-recovery pass is specifically designed to recover edge acuity on low-res inputs without introducing the halos or ringing artefacts that small-kernel sharpening creates. For photos below 1000px, the Photo preset gives the most natural lift; for textile swatches below 500px, Textile preserves weave geometry best.
AI photo enhancer for blurry shots
For mildly soft photos, Smart Upscale with the Photo preset recovers edge acuity and adds perceived sharpness without over-correcting skin tones. For genuinely blurry inputs — motion blur, out-of-focus shots, heavy JPG compression — the AI Image Sharpener or AI Enhance mode (free with signup) runs the Texloom AI that rebuilds detail instead of just sharpening what's already there.
Upscale textile patterns and scanned artwork
The Textile preset is tuned on fabric data — sharpenThreshold 12 so fine thread and weave detail isn't flattened, and noise reduction held to 0.15 so scan texture is preserved. Ideal for vintage pattern archives or hand-drawn repeats heading to production. If your scan has moiré or halftone dots, run it through our AI Texture Remover first, then upscale.
Upscale to 8K, 12K, or 16K
For production print, 4× scale unlocks outputs up to 16384×16384 px — enough headroom for large-format wall panels, 300 DPI fabric runs, or billboard reproduction from a moderate-resolution source. 4× requires a free account; the algorithm itself is the same studio-grade Smart Upscale, the cap is the gate. Check Print Calculator before choosing a scale.
When to use 2×, 3×, or 4×
Web → product photo
E-commerce images, social media assets, pattern previews. Fast, predictable, rarely needs more.
Sample → design review
Low-res scans of hand-drawn art, vintage pattern archives, client reference images you need to present clearly.
Reference → production
Turning a moodboard image into a printable repeat. Legacy artwork recovery. Anything headed for large-format output at 300 DPI.
Four steps, two minutes
Upload your image
Drop any JPG, PNG, or WEBP up to 10MB. Works with photos, patterns, logos, and scans.
Pick a scale factor
Choose 2×, 3×, or 4× upscaling based on your output size. 4× is ideal for large-format production printing.
Let AI enhance detail
Our model adds real detail — sharper edges, cleaner textures — not just pixel stretching.
Download the result
Export as PNG or TIFF at up to 16000×16000 pixels. Lossless, production-ready.
Built for production work
Most free upscalers cap at 2× or watermark their output. Ours doesn't.
No watermarks, ever
Every output is clean — free or paid. No logos, overlays, or hidden marks.
Color fidelity preserved
Delta E <2.0 against source — the tolerance commercial print actually requires.
Production-grade output
Up to 16000×16000 pixels. Ready for rotary, digital, and wide-format.
Pattern-aware AI
Tuned on textile data. Weaves and motifs come out crisper than on generic upscalers.
