Free Image Tools for Web Developers

Developer-focused image utilities for web performance optimization. Compress for Core Web Vitals, encode to Base64, generate favicons, create sprite sheets, and automate batch processing — all in your browser.

Recommended Tools for Developers

Image Compressor

Optimize images for web delivery — reduce LCP and improve Core Web Vitals scores.

Image to Base64

Convert small icons to data URIs to eliminate HTTP requests and reduce render-blocking.

Favicon Generator

Generate all required sizes (16px to 512px) plus Apple Touch Icon from one source image.

Sprite Sheet Generator

Combine multiple icons into a single image to reduce network requests.

OG Image Generator

Generate Open Graph images programmatically for dynamic pages and blog posts.

Format Converter

Convert to WebP/AVIF for modern format delivery with JPEG/PNG fallbacks.

File Type Detector

Detect actual image format from binary signature — debug mislabeled uploads.

Placeholder Generator

Create solid-color placeholders for layout development and wireframes.

QR Code Generator

Generate QR codes for app deep links, payment flows, or documentation.

Metadata Stripper

Strip EXIF data from user uploads for GDPR compliance and privacy.

Common Use Cases

  • •Compress all images in a build pipeline for production
  • •Convert to WebP/AVIF with fallback images for <picture> element
  • •Generate favicon package for new web projects
  • •Encode critical icons as Base64 data URIs
  • •Create CSS sprite sheets from icon libraries
  • •Strip EXIF/GPS metadata from user-uploaded images
  • •Detect and validate image file types on upload
  • •Generate OG images for blog posts and landing pages
  • •Create placeholder images for development mockups

Pro Tips for Developers

1Serve images in AVIF → WebP → JPEG order using <picture> for optimal compression
2Base64 encode only images under 10KB — larger ones are better served as separate files
3Always strip EXIF metadata from user uploads — GPS data is a privacy/GDPR liability
4Use progressive JPEG for above-the-fold hero images — perceived loading is much faster
5Generate favicons once during build, not on each request — cache the results
6Set explicit width/height on <img> tags to prevent CLS (Cumulative Layout Shift)

100% Private — No File Uploads

All tools process images entirely in your browser. Your files never leave your device — no server uploads, no data retention, no third-party access. Safe for client work, personal photos, and confidential content.
