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.
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.
Standard
/api/v1/800x450?text=Product+Image Dimensioned placeholders for cards, grids, and missing product media.
Thumbnail
/api/v1/thumbnail/1200x630?text=Blog+Post+Title&style=soft Featured-image style art with safe-zone decoration, themes, and category pills.
Avatar
/api/v1/avatar/128?text=JD Circular initials for users, teams, org logos, and comment authors.
Square
/api/v1/square/400?text=Tile Square tiles for ecommerce grids, collections, and inventory slots.
Banner
/api/v1/banner/1200x400?text=Campaign Wide hero banners for campaigns, docs headers, and landing previews.
Skeleton
/api/v1/skeleton/640x360 Static skeleton blocks that preserve layout while async media resolves.
Animated
/api/v1/animated/skeleton/640x360 Shimmer, pulse, wave, gradient, and dot motion for loading states.
Chart
/api/v1/chart/line/800x500 Dashboard-ready chart art for reports, metrics cards, and analytics previews.
Gradient
/api/v1/gradient/800x450 Static brand gradients for polished empty media, cards, and hero slots.
Blur
/api/v1/blur/800x450 Soft blurred placeholders before high-resolution media arrives.
Pattern
/api/v1/ai/800x450?context=saas&mood=minimal Deterministic decorative backgrounds with optional context and mood.
Capabilities
Everything you need beyond width × height.
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
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
Reserve analytics card space with bar, line, pie, area, donut, scatter, radar, and heatmap skeletons.
/api/v1/chart/bar/800x400 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.

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.
