LQIP Placeholder

Create tiny low-quality image placeholders (LQIP) with inline base64 data URIs for instant page rendering while full images load. Dramatically improves perceived loading performance for image-heavy web pages. Generated entirely on your self-hosted server.

Features

  • Generates tiny placeholders typically under 1KB in base64-encoded data URIs
  • Configurable output size and blur level for quality-size tradeoff control
  • Outputs ready-to-embed base64 data URI strings for direct HTML or CSS use
  • Preserves aspect ratio to prevent cumulative layout shift during loading
  • Batch generation for processing entire image directories at once

What you can do

  • Generating blur-up placeholder images for a lazy-loaded photo gallery website
  • Creating base64 LQIP strings for server-side rendered pages to eliminate layout shift
  • Producing thumbnail previews for a content management system image library

Frequently asked questions

How small are the generated placeholder images?
Placeholders are typically under 1KB as base64 strings, small enough to inline directly in HTML without meaningful page weight impact. Generation runs on your self-hosted SnapOtter server.
Can I control the blur level of the placeholder?
Yes, you can adjust the size and blur parameters to balance between a recognizable preview and minimal file size. All processing is local, so iterating on settings is instant and free.
What format is the output?
The output is a base64-encoded data URI string that you can embed directly in img src attributes or CSS background properties. Everything is generated on your own self-hosted server with no external dependencies.
