Image Optimization Best Practices

🖼 Choose the right format
Photos → JPEG/WebP. Graphics with flat colors/transparency → webp or lossless WebP.
📐 Resize before compressing
Shrinking dimensions first saves far more bytes than quality alone.
🧭 Respect orientation
Use EXIF-aware decoding to avoid sideways images from phones.
🔍 Check sharpness
If results look soft, try exact pixel sizes and avoid multiple re-encodes.

Technical Implementation

⚙️ Load & auto-rotate with EXIF
Ensure images respect original orientation metadata when processing.

🛠️ What this tool can do

  • Resize by width/height (keeps aspect ratio)
  • Compress JPEG/WebP with adjustable quality
  • Convert between webp • JPEG • WebP
  • Auto-rotate based on EXIF orientation
  • Batch multiple images (drag & drop)

All processing is local—no uploads. Great for privacy and speed.

📋 Inputs

  • Files: webp, JPEG, WebP (static)
  • Target size: max width/height or exact size
  • Quality: 1–100 (mapped to 0.01–1.0 for encoders)
  • Format: webp (lossless, alpha) • JPEG (lossy) • WebP (lossy/lossless)

⚙️ Output characteristics

  • Transparency: Keep alpha with webp/WebP; JPEG fills transparent areas with a background color
  • Color space: sRGB canvas output
  • Orientation: EXIF respected (auto-rotate) where supported

🎯 Contain vs. Cover

  • Contain: fit inside the box, no cropping (default)
  • Cover: fill the box entirely; crops overflow (good for thumbnails)

🧩 How to use

  • Drag & drop images or use Select Files.
  • Choose target size (e.g., 1600 px max width) and format (WebP/JPEG/webp).
  • Set quality (e.g., 80 for JPEG/WebP). webp ignores quality for lossless output.
  • Pick contain for safe fit or cover to crop-fill thumbnails.
  • Click Convert, then Download your optimized image(s).

💡 Tips

  • WebP often yields the smallest files with good quality.
  • For crisp UI assets, keep webp or use lossless WebP.
  • JPEG/WebP quality ~70–85 is a good balance for photos.
  • Match export size to your layout and device pixel ratio (e.g., 2× for retina).

Image Compressor – Frequently Asked Questions

Downscale width/height and use JPEG/WebP with a lower Quality setting, then download.

Export as JPEG, webp, or WebP. Quality applies only to JPEG/WebP.

Yes. Canvas export typically strips EXIF/metadata.

No. Everything happens in your browser; nothing is sent to a server.

webp is lossless, so there’s no quality/size trade-off exposed via the slider.
