How is this different from placeholder.com or picsum.photos?

Both of those are remote services — you embed a URL and a CDN renders a PNG on the fly. That works until the service is slow, rate-limits you, gets blocked by your corporate firewall, or quietly disappears (which has happened to two popular placeholder hosts in the last three years). This tool renders locally in your browser using the Canvas 2D API, so there's no third-party dependency in your mockup — paste the PNG into Figma and it ships with the file. You also get WebP and custom hex colors, which placeholder.com does not.

Will my custom text or color choices be uploaded anywhere?

No. Every pixel is drawn by your browser's ` ` element and downloaded as a blob via `URL.createObjectURL`. The tool page makes zero network requests once it has loaded — open DevTools → Network → clear, then click "Download" and watch nothing fly across the wire. Safe for confidential project names, internal brand colors, or NDA mockup labels.

What's the largest image I can generate?

Width and height are each capped at 4000 px, which gives you a 16 megapixel canvas — large enough for retina hero images and print-size mockups. The hard ceiling is your browser's canvas memory limit (most desktop browsers crash beyond 16,384 px in either dimension). If you need 4K-by-4K, the download will be roughly 1–4 MB as PNG, 200–800 KB as JPG at quality 0.9, and 100–400 KB as WebP — same pixels, very different file sizes.

Why is the WebP file so much smaller than the PNG?

WebP uses modern lossy compression (VP8-derived) tuned for photographs and gradients; PNG uses lossless DEFLATE designed for screenshots and pixel art. For a flat-color placeholder with a single text label, WebP can hit 5–10× smaller than PNG while looking visually identical. Use WebP whenever the consumer is a browser (every modern one supports it natively); use PNG when you need to drop the file into older tools like legacy Photoshop or email clients that haven't caught up.

Can I batch-generate all the sizes my design system needs?

Yes — click the Standard Sizes bar at the top and the tool will download all five canonical sizes in sequence (Hero 1920×1080, OG 1200×630, Icon 512×512, Mobile 750×1334, Square 1080×1080). That covers the OpenGraph card, the app icon, the mobile hero, the desktop hero, and the social square in one click — the exact set most marketing landing pages and product pages need on day one. Each file inherits your current color and format settings.

Filling an OG card before the real hero art exists

You ship a landing page Monday but the designer's hero won't land until Thursday. Generate a 1200×630 placeholder in your brand's hex (say #0F172A on #38BDF8), label it "OG draft", and drop the PNG into your meta tags. The Twitter and Slack unfurls look intentional instead of broken, and you swap one file when the real art arrives.

Seeding a Figma frame stack with exact pixel dimensions

A designer building a 12-screen mobile flow needs every frame filled so stakeholders stop asking "is this blank on purpose?" Generate five 750×1334 placeholders with different labels ("Onboarding 1", "Onboarding 2"...), paste them in, and the prototype reads as deliberate. Each image carries its own dimension text so nobody mistakes a 9:16 for a 16:9.

Stress-testing a responsive grid with mixed aspect ratios

A front-end dev wiring a CSS grid wants to see how cards reflow when images are 512×512, 1920×1080, and 750×1334 all at once. Generate three placeholders in seconds, drop them into the grid, and watch where the layout breaks before any real photography exists. No Lorem Picsum rate limits, no flaky CDN during a demo.

Building offline demos that survive a dead conference WiFi

You're presenting a prototype at a venue with hostile WiFi. Remote placeholder URLs render gray boxes the moment the network drops. Bake local PNGs into the build instead: every image is a real file on disk, so the demo looks identical whether you have 100 Mbps or zero. Generate the set once, commit them, and never sweat the room's network again.

What this tool does

A 100% client-side placeholder image generator for designers, developers, and marketers who need throwaway pixels right now. Pick any width and height from 50 to 4000 px, choose a background and foreground color, set a custom label (or let it auto-fill the pixel dimensions like "1920×1080"), and download a PNG, JPG, or WebP. The live preview canvas updates the instant you tweak a knob — no debounce lag, no API call, no upload. One click on the Standard Sizes bar regenerates the five sizes every product ships: Hero (1920×1080), OG card (1200×630), Icon (512×512), Mobile portrait (750×1334), and Instagram square (1080×1080) — perfect for filling out a Figma mockup, a marketing brief, or a fresh Next.js project before the real art lands. Bytes never leave your tab; the only thing that hits the network is the file download you trigger.

Common pitfalls

Leaving the foreground and background colors too close (e.g.
Exporting JPG for a placeholder that has crisp text edges; JPG smears the label with artifacts. Use PNG or WebP for any image carrying a text label, and save JPG for photographic fills only.
Generating a 4000×4000 PNG when you only need a 600px card preview, then wondering why the file is 4 MB — match the pixel size to the slot it fills, since browsers scale down but never reclaim the wasted bytes.

Privacy

Everything runs in your browser tab. The width, height, colors, and any custom label you type are drawn onto a local `<canvas>` element and saved via a blob download — none of it is sent to a server, and none of it lands in the page URL unless you explicitly share a link. After the page loads it makes zero network requests, so confidential project names, internal brand hex codes, and NDA mockup labels stay entirely on your machine.
