Free AI Image Sharpener
Fix blurry photos with AI. Recover edge detail, clean up soft focus, keep colors intact — your image is never stored, copied, or used for training.
What is AI image sharpening?
AI image sharpening recovers the edge detail softened by mild blur, low focus, JPG compression, or scanning artefacts. Unlike a one-size-fits-all unsharp-mask filter — which indiscriminately amplifies every pixel boundary, including noise and skin texture — a content-aware sharpener identifies which edges are real structure and tightens only those, leaving flat areas and gradients untouched.
For textile, portrait, and print work this matters more than casual photography. A scanned vintage pattern needs clean lines without noise amplification; a portrait needs crisp eyes without skin that looks plastic. Our sharpener runs studio-grade unsharp-mask + high-pass recovery with per-preset edge-aware masking, so each content type gets the right treatment. If the result still isn't enough — or the source is truly blurry rather than just soft — pair it with our AI Image Upscaler at 2× to sharpen and enlarge in one pass.
Smart Sharpen vs AI Restore
Smart Sharpen (what you're using here) instant with preset-tuned sharpening + edge-aware masking — the same engine paid Studio users run on the free mode. AI Restore is a different beast: a cloud-hosted Texloom AI that rebuilds detail from genuinely blurry inputs, not just sharpens existing edges.

What people use our AI sharpener for
Fix a blurry photo online
Drop a soft or mildly blurry photo and Smart Sharpen recovers edge detail in about 2 seconds — instant, no upload, no signup for the first try. Unsharp mask with edge-aware masking catches real structure (eyes, lettering, pattern edges) without amplifying skin texture, noise, or JPG compression artefacts.
Unblur an image for free
For mildly soft inputs — out-of-focus by a touch, low-light camera shake, heavy compression — Smart Sharpen lifts edge acuity back to crisp. If the source is genuinely out-of-focus or motion-blurred, AI Restore (free with signup) is the tool to reach for — it rebuilds detail with Texloom AI instead of just sharpening existing edges.
Sharpen a JPG without losing colors
Smart Sharpen operates on luminance, so colors stay exactly where they were — critical for brand work, product photos, and any design heading to print. Output is a clean PNG with preserved color profile. Need a different output format? Pass the result through our Format Converter for PNG → JPG / WEBP / TIFF conversion with quality control.
Sharpen a scanned image or vintage pattern
Use the Textile preset for fabric scans and vintage pattern archives — it's tuned to preserve weave and thread detail with moderate amount and higher detail recovery. If your scan shows halftone dots or moiré, run it through the AI Texture Remover first, then sharpen.
Sharpen a portrait without ruining skin
The Portrait preset uses a gentler amount and higher denoise value so skin stays natural while eyes, lips, and hair edges get the lift they need. It's the preset we ship tuned for faces — never use Illustration or Textile on a portrait or you'll amplify pores and skin noise.
Sharpen low-res images before upscaling
Sharpening before upscaling gives the upscaler cleaner edges to work with. Run Smart Sharpen first, then feed the output to our AI Image Upscaler for 2× or 3× output with better detail retention than doing either step alone.
When to use Photo, Portrait, Illustration, or Textile
Everyday defaults
Soft product shots, street photography, travel photos. Balanced amount and denoise — the safest pick for anything that isn't portrait or pattern.
Faces and skin
Gentler amount + higher denoise so skin stays smooth while eyes and hair get real edge recovery. Never use Photo or Textile on a face.
Line art and graphics
Strong edge recovery, zero denoise so lines stay crisp. Best for digital art, logos, scanned sketches, and any content with clean-color regions.
Weaves and patterns
Tuned on fabric data — preserves thread and weave detail, moderate edge-aware masking to protect motif structure. Use this on fabric scans, swatches, and repeat artwork.
Four steps, under a minute
Upload your image
Drop any JPG, PNG, or WEBP up to 10MB. Photos, portraits, scans, or illustrations — our AI picks the right sharpen profile automatically.
Pick a strength
Light for photos that are already close to crisp, Medium for most everyday use, Strong for clearly blurry scans and soft captures.
Let AI sharpen the edges
Our AI recovers lost detail, tightens edges, and restores clarity without inventing texture that wasn't there. Output size matches your input.
Download the result
Export as a lossless PNG ready for anywhere — print, web, social, client deliverables. Your design is never stored, copied, or used for training — it stays yours.
Not just a sharpen filter
Every free online sharpener applies one generic kernel. Ours adapts per content type and protects what shouldn't be amplified.
Content-aware tuning
Photo, Portrait, Illustration, and Textile each use different amount/radius/denoise profiles — portraits don't get the harsh treatment that ruins skin tones.
No over-sharpening halos
Edge-aware masking prevents the white/black halos around subjects that plague cheap sharpen tools.
Color fidelity preserved
Sharpening affects luminance only — colors stay exactly as they were. Critical for brand work and textile design.
Your designs stay yours
Never stored on our servers, never copied, never used to train AI, never shared with anyone. Your file leaves with you.
