Free SVG background generator

How this SVG background generator works

Every background starts from a seed — any text you like. The seed feeds a deterministic random-number generator, so the same seed always redraws the same background, byte for byte. That makes every design a permalink: the URL holds your seed and settings, and sharing the link shares the artwork itself, still fully editable. On top of the geometry sits a hand engine — tremor noise, line-weight variance and torn edges — that is what makes the output look drawn rather than computed. The SVG it writes is deliberately clean: flat fills and strokes only, no gradients and no filters, so files stay tiny and easy to edit by hand. Not sure where to start? The ready-made styles strip above the preview holds a dozen curated looks — every one is itself just a seed, so click one and remix.

Two promises worth being precise about. What you see is byte-for-byte what you ship: the engine is deterministic down to the character, guarded by an automated suite of more than 12,000 checks that locks every seed's output — a permalink from today renders identically next year. And no tiles, no seams: nothing here is a repeated pattern block; every artwork is drawn edge-to-edge at your exact canvas size, so there is no seam to hunt for and no tile rhythm for the eye to catch.

SVG wave backgrounds

The Waves style is a classic svg wave generator with an ink temperament: three to seven stacked bands, each darker than the one behind it, like torn strips of paper laid over each other. The Hand slider is the signature control — at zero the bands are smooth editorial waves; pushed right, a fine second layer of noise tears each edge into a deckled, hand-torn contour. Flip them to hang from the top of the frame, or pick the Section divider canvas (1600 × 240, transparent) to cut a wave separator for the seam between two page sections. Waves work anywhere a section needs a soft horizon: page footers, hero bottoms, slide backdrops.

SVG blob generator, etched in ink

Most blob generators fill their shapes with gradient goo. This one hatches them. Each organic blob is drawn as a smooth closed curve, then filled with hundreds of slightly wobbling parallel strokes — like a woodcut or an engraving — and where two blobs overlap, their hatch angles cross into real cross-hatching. The result reads as printmaking, not vector candy: backgrounds with texture and weight at a few dozen kilobytes. Prefer a quieter mass? Switch the fill to solid (flat inked shapes, the classic blob-maker look) or outline (drawn keylines), and set the shape count anywhere from a composed scatter down to a single blob — one shape on a transparent background is a ready-to-use SVG blob element. A single blob also exports as a responsive CSS clip-path (the Copy clip-path button appears when one shape is selected), so you can mask photos and cards with an organic shape that scales with the element.

Abstract SVG shape generator

Field Notes scatters small abstract shapes — ticks, rings, crosses, dots and commas — across the canvas with even, considered spacing, the way a compositor would set loose type. No mark is a perfect line or circle: every glyph carries a slight wobble, so the sheet looks annotated by hand. It is the quietest of the six styles and the best behind real content, from hero text to long reading pages. Switch its layout to Grid and it becomes a ruled lattice instead: dots only on an A4 or US Letter canvas make free printable dot grid paper (about a 5 mm pitch at the default density), with the Hand slider adding the gentle irregularity of a hand-ruled notebook.

Flowing contour line backgrounds

Contours combs dozens of ink lines across the page through a single coherent flow field, so they bunch and breathe like the grain of wood or the lines of a pen-plotter drawing. Rotate the flow in 45° steps, thin it out to a whisper or densify it into fabric. Because it is nothing but strokes, this style produces the smallest files of the six relative to how much surface it covers.

Halftone pattern generator

Halftone is the print shop's answer to gradients: a rotated screen of dots whose size carries the tone, exactly how newspapers and screen prints have rendered shading for a century. Each sheet gets a seeded sweep of light clouded with noise, so the dots swell into shadow on one side and dissolve into open paper on the other — a gradient with zero gradient elements in the file. Set the screen angle in 45° steps (45° is the classic), tighten the screen with Density, and push the Hand slider to loosen press-perfect rows into hand-stippled texture. The whole plate is one ink — or one accent color — in a single compact path, so even a dense screen stays light and recolors with one edit. Try the Benday and Pressroom styles in the gallery for ready-made looks.

Quad-tree panel backgrounds

Quad Tree splits the canvas the way image compression does: divide into four, then keep dividing where the seed says to, and fill each cell with a flat panel of ink. The result is an uneven mosaic — dense clusters of small dark panes opening into large quiet ones, with a hair of paper grout between them and a single accent panel anchoring the busiest corner. Density sets how deep the subdivision runs; the Hand slider loosens the panel edges from ruled-straight to drawn-by-hand. Pure rectangles, so the files stay small and recolor with one edit. Try the Mosaic and Precinct gallery styles.

Animated SVG backgrounds, no JavaScript

Waves and Contours carry an Animate toggle: the strata drift in slow parallax, the line field breathes. The motion is pure CSS keyframes written into the SVG itself — no JavaScript, no GIF, no runtime library — so the export is still one small .svg file that animates wherever it is inlined. It honors the visitor's prefers-reduced-motion setting and holds still for anyone who opts out, and the drift is seeded exactly like the geometry: the same permalink always reproduces the same motion. Open in CodePen drops the animated background into a ready-made hero section, prefilled and unsaved, to remix.

Where to use these backgrounds

Hero sections and landing pages

Pick a canvas preset that matches the slot — desktop hero, full HD, social card, square or story — and keep density low if a headline sits on top. The Ink palette is deliberately quiet under typography, and the transparent-background option lets the artwork float over your own brand color. The readout under the preview measures the artwork's actual pixels and reports worst-case WCAG contrast for dark and light headline text, so you know a background is text-safe before it ships — AA needs 4.5:1.

How to set an SVG background in CSS

Press Copy CSS and the whole image lands in your stylesheet as a data URI — one paste, zero extra requests:

.hero {
  background-image: url("data:image/svg+xml,…");
  background-size: cover;
}

Or download the .svg file and reference it like any image — background-image: url('/img/background.svg'), in an <img> tag, or inlined straight into the HTML.

Figma, Slack, Notion and Docs

Copy PNG puts the raster straight on your clipboard — paste it into Figma, Slack, Notion or Google Docs without touching a file. Even better for Figma: press Copy SVG and paste — Figma converts the markup into fully editable vector layers, flat fills and all, ready to recolor per layer.

Slides, social cards and print

The PNG export rasterizes the artwork client-side at 1× or 2× of the chosen canvas (up to ~16 megapixels; the filename states the exact pixel size) — crisp enough for decks, Open Graph images and short-run print. Because the output is flat ink rather than gradient blends, it survives cheap printing and photocopying the way etchings always have.

License: free for commercial use, no attribution

Everything this tool generates is yours, outright. Each background is produced on your machine from your seed — we never see it, store it or watermark it. Use it in personal and commercial projects, for clients, in products, on merch, with no attribution and no account, forever. The only carve-out: don't repackage the raw outputs into a stock collection or a competing generator. That's the whole license.
