Generate gradient PNGs with custom stops
Design a linear or radial gradient with any number of color stops, tune the angle, set the output size, and download a clean PNG. Runs locally.
How it works
Pick an image, tune the options, then download the result. Everything runs in your browser.

Pick size
Set the output width and height up to 4096 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 · bytes1200x630 · loadedcanvas: 1200x630

Choose gradient type
Linear runs along an axis; radial fans from the center outward.
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 · tunablelinear · livemode = linear

Add color stops
Add any number of color stops with hex colors and a 0–100 position.
Pixel work runs on the Canvas 2D context —

Download PNG
Save a clean PNG ready for OG images, banners, or backgrounds.
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.
OG hero images
Quick social cards with bold gradient 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.
1200x630App backdrops
Soft fills for splash screens and onboarding. 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-tunableDesign mockups
Drop in as a placeholder while building layouts. 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-awareCSS fallback
Static PNG for browsers that ignore CSS gradients. 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-safeMarketing assets
Generate banners without firing up Figma. 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-sideEmail assets
Bake gradients into inline images for newsletters. 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.
