Free Image Resizer & Compressor
Reduce image size for websites, social media, or email – no quality loss
Quick Resize (Basic)
Why Resize and Compress Images?
Large images slow down websites, take forever to email, and waste storage space. Our tools help you reduce image size while keeping acceptable quality. Use the basic resize tool above (works in your browser – no upload to server) or click advanced tools for more control.
Common Use Cases
- Website speed: Compress images to under 200KB for fast loading (Google rewards fast sites).
- Email attachments: Most email services block >25MB – compress to 1-2MB.
- Social media: Facebook, Instagram, WhatsApp automatically compress, but pre-compressing gives you control.
- E-commerce: Product photos need to be large enough to see details but small enough for fast browsing.
Recommended Image Sizes by Platform (2026)
- Website hero images: 1920×1080 pixels, file size under 300KB (WebP).
- Product thumbnails: 300×300 pixels, under 50KB.
- Email signatures: 300×100 pixels, under 20KB.
- WhatsApp status/profile: 500×500 pixels, under 100KB.
Lossy vs Lossless Compression – What to Choose?
Lossy (JPG, WebP): Removes some data to shrink file size. Best for photos where small quality loss is invisible. Lossless (PNG): Keeps all data – important for logos, screenshots, graphics with text. Our recommended compressor (iLoveIMG) lets you choose quality level.
Tips for Best Results
- Always keep original file before compressing.
- For web, use WebP format (30% smaller than JPG at same quality).
- Resize dimensions first (smaller width/height), then compress.
- Avoid multiple compressions – each re-compression reduces quality.
