Free Online Image Optimizer — Optimize Images for Web
Optimize your images for web use with our free online image optimizer. Upload images to strip unnecessary metadata, resize to optimal web dimensions (max 2000px), and compress for faster page loading. Using WebAssembly-powered codecs, all processing happens locally in your browser — your images never leave your device. Perfect for web developers, bloggers, and anyone who wants faster-loading websites.
Upload one or more images to optimize for the web.
Configure optimization settings: metadata stripping, max dimension, and quality.
Download the optimized images individually or as a ZIP archive.
Tips for Optimizing Images
- Stripping metadata (EXIF, GPS) removes camera info and can reduce file size without affecting image quality.
- Setting a max dimension of 2000px is ideal for most websites — large enough for HD displays but much smaller than original camera files.
- WebP offers the best balance of quality and file size for web use, with broad browser support.
Frequently Asked Questions — Image Optimizer
Is the image optimizer free?
Yes, completely free. No registration, no hidden charges, and no file size limits. All optimization happens locally in your browser.
What does image optimization do?
Our tool: 1) Strips EXIF and GPS metadata from the image, 2) Resizes to your chosen max dimension (default 2000px), 3) Compresses at optimal quality using WebAssembly codecs.
Why should I strip metadata?
Image metadata (EXIF) contains camera settings, GPS coordinates, and software info — often several hundred KB of unnecessary data. Stripping it reduces file size and protects your privacy.
What is the recommended max dimension?
2000px on the longest side is recommended for most websites — it's sharp on Retina/HiDPI displays while being much smaller than typical camera resolutions (4000-6000px).
What image formats are supported?
Input: JPEG, PNG, WebP, AVIF, JPEG XL. Output: WebP (recommended), JPEG, or original format.
Can I optimize multiple images at once?
Yes, batch optimization is fully supported. Upload multiple images and optimize them all with the same settings.
Does optimization reduce image quality?
The tool uses 85% quality by default, which provides excellent visual quality while significantly reducing file size. Metadata stripping causes no quality loss.
