Generate noise textures in your browser
White, grayscale, RGB, or Perlin-style noise textures for backgrounds, grain overlays, and design mockups. Runs locally.
How it works
Pick an image, tune the options, then download the result. Everything runs in your browser.
- 01
Set size
Pick width and height up to 2048 each.
Files stay in memory as an
HTMLImageElement— the original bytes are never uploaded, and EXIF metadata is preserved until you explicitly transform it.sizeuploadcanvaslocaldecodesize · bytes512x512 · loadedcanvas: 512x512

Pick a noise type
White is dotted pure black/white. Grayscale or RGB use random distributions. Perlin is smooth gradient noise.
Encoder quality is exposed where the format supports it — JPEG and WebP get a
0–1quality slider; PNG is lossless. Options re-render the canvas immediately.typeoptionslive previewencoderqualitytype · tunablegrayscale · livegenerate(grayscale)

Tune intensity
0 produces mid-gray; 100 uses the full range.
Pixel work runs on the Canvas 2D context —

Download PNG
Save the texture as a transparent-safe PNG.
Downloads ship via a hidden anchor with an object URL — no server round-trip, and the file on disk is untouched. The output filename inherits a sensible suffix.

Browser-only image work that scales
Convert with quality control
JPEG/WebP let you pick a 0–1 quality. Default 0.92 is a good compromise of size and visible quality.
PNG isn’t free
Use PNG only for transparency or sharp edges. For photos, WebP is smaller at the same perceived quality.
Strip EXIF for privacy
Photo EXIF often contains GPS, camera model, and timestamps. Strip before sharing public uploads.
Watch the colour profile
Convert to sRGB before web export. Wide-gamut images render oversaturated in non-managed browsers.
AVIF when it’s available
AVIF beats WebP on size at the same quality. Detect support via <picture> with fallbacks.
Lazy-load below the fold
Add loading="lazy" on <img>. The browser handles scheduling — no IntersectionObserver needed.
When to use this tool
Common workflows it speeds up.
Background grain
Subtle film-grain overlay for UI backgrounds. Decoded into a Canvas 2D context — original bytes never leave the tab, so you can process customer-uploaded photos, internal screenshots, or sensitive diagrams without privacy concerns.
px-perfectTexture overlays
Mix into mockups for tactile feel. Encoders expose quality 0–1 where the format supports it (JPEG, WebP); PNG and AVIF stay perceptually lossless. Pick 0.85 for web, 0.95 for archival, 0.7 for thumbnails.
quality-tunableGame backgrounds
Static-noise screens for retro game UI. Pair with the EXIF Stripper before sharing user-uploaded photos publicly. Camera serial numbers, GPS coordinates, and timestamps often hide in image metadata and leak more than the picture itself.
format-awareProcedural art
Perlin maps for generative wallpapers. Output preserves colour profile (sRGB) so it renders consistently across browsers, monitors, and print pipelines. Wide-gamut workflows can opt into Display P3 for modern Apple devices.
EXIF-safeTest fixtures
Random pixel input for image-processing tests. Re-runs only on option changes, never on window resize, so the canvas stays responsive on large images. drawImage uses the browser's bilinear filter for fast resampling.
client-sideCSS textures
Tileable noise PNGs for CSS backgrounds. Downloads as .png, .jpg, .webp, or .avif with the correct MIME so editors apply native handling on save. The filename inherits a sensible suffix derived from the input.
