Features

Production image fallbacks, not placeholder clip art.

fallback.pics gives teams URL-addressable infrastructure for every missing-image state: product cards, charts, avatars, gradients, blog thumbnails, skeleton loaders, blur previews, and broken-src recovery—cached at the edge like static assets.

Platform

Built for teams that cannot afford broken image states.

One URL replaces fragile placeholder assets across web, mobile, email, and CMS surfaces. Generate once, cache globally, and standardize fallback behavior in design systems and code review.

No key public GET routes
SVG + raster PNG, JPEG, WebP
10–5000px bounded dimensions
Immutable 1 year cache policy
Edge Cloudflare delivery
CORS browser-safe responses

URL-native API

Every fallback is a readable GET URL. No SDK, upload pipeline, or auth handshake for public routes.

/api/v1/800x450?text=Product

Deterministic output

Same URL always returns the same image. Safe to cache at the CDN, embed in emails, and review in PRs.

Cache-Control: immutable

Brand-safe controls

Path colors, labels, thumbnail themes, and preset behavior stay visible and versionable in your codebase.

/api/v1/800x450/18181B/FFFFFF?text=Acme

Broken-image recovery

Swap failed src values with dimension-matched fallbacks via onerror handlers or framework error boundaries.

onerror → fallback.pics URL

Presets

Preset routes for real product surfaces.

Each preset encodes layout, motion, data art, or decoration so you do not rebuild avatars, chart previews, thumbnail safe zones, or loader shimmer by hand. Click any card to open the live image.

Capabilities

Everything you need beyond width × height.

Multi-format delivery preview

Multi-format delivery

Default SVG for crisp UI. Append .png, .jpg, .jpeg, or .webp when raster output is required.

/api/v1/800x450.png?text=Raster
Blog thumbnail engine preview

Blog thumbnail engine

Generate OG-safe featured images from post titles with style, theme, and deterministic seed options.

/api/v1/thumbnail/1200x630?style=rings&theme=blue
Chart placeholders preview

Chart placeholders

Reserve analytics card space with bar, line, pie, area, donut, scatter, radar, and heatmap skeletons.

/api/v1/chart/bar/800x400
Gradient placeholders preview

Gradient placeholders

Use deterministic purple-to-blue gradients when a visual surface needs polish without custom assets.

/api/v1/gradient/800x450

CORS-enabled responses

Use fallbacks in canvas previews, design tools, and cross-origin dashboards without proxy workarounds.

Access-Control-Allow-Origin: *

Explicit API errors

Invalid dimensions and unknown paths return structured API errors—not homepage HTML—so monitoring stays clean.

400 Invalid dimensions

Performance

Fast enough to feel invisible in the UI.

Edge-first generation

Images are generated at the Cloudflare edge. Repeat requests behave like static assets, not application round-trips.

SVG-first defaults

Vector output stays tiny and sharp at any zoom. Raster formats are available when your pipeline requires bytes.

Long-lived caching

Deterministic URLs ship with immutable cache headers so product grids, emails, and CMS previews stay fast globally.

Privacy by design

No cookies, client SDK, or image uploads. Keep labels user-facing—avoid secrets or regulated data in URL text.

Operational tip: Match fallback dimensions to the final image slot, keep URLs deterministic for repeated states, and prefer SVG unless your pipeline requires raster bytes.

FAQ

Common feature questions.

What makes fallback.pics different from placeholder.com-style services?

fallback.pics is built as production infrastructure: preset routes for real product states, blog thumbnails, immutable caching, explicit API errors, and guides for broken-image recovery—not just dimension labels.

Do I need an API key?

No. Public GET routes under /api/v1 work without authentication. Enterprise deployments can add custom domains and support terms by agreement.

Which preset should I start with?

Use standard width×height for general slots, avatar for people, thumbnail for blog/OG art, chart for dashboard previews, gradient for branded media slots, skeleton or animated for loaders, and blur for progressive image reveals.

Can I use fallbacks in production emails and CMS fields?

Yes. Deterministic URLs cache globally and work anywhere an image URL is accepted—HTML, React, CSS background-image, Markdown, and rich text editors.

Standardize image fallbacks across your product.

Start with one high-traffic image slot, then expand into team conventions, showcase-approved URLs, and enterprise custom domains with support windows and SLA commitments by agreement.
