Images are the #1 cause of slow websites. A single unoptimized 5MB hero image can take 10 seconds to load on a 3G mobile connection, causing users to bounce instantly. Google also penalizes slow sites in search rankings.
The Image Compressor allows you to shrink image file sizes intelligently, often reducing them by 70-80% while keeping them crisp to the human eye.
Lossy vs Lossless Compression
Understanding the difference is key:
- Lossless: Removes metadata (EXIF date, camera model) and optimizes the internal coding without changing a single pixel. Savings: ~10-20%.
- Lossy: Intelligently removes color details that the human eye is bad at seeing (Quantization). Savings: ~70-90%.
Our tool uses smart lossy compression (like TinyPNG) to find the perfect balance.
Format Specifics
JPEG
Best for photos. Uses Discrete Cosine Transform (DCT). You can adjust the "Quality" slider (0-100). We recommend 80 for the web.
PNG
Best for logos and screenshots with text. Our tool converts 24-bit PNGs to indexed 8-bit PNGs where possible, massively reducing size.
WebP
The modern standard. Google developed WebP to replace both JPEG and PNG. It is typically 26% smaller than PNGs and 25-34% smaller than JPEGs.
Why Compress Locally?
Other tools ask you to upload your files to a server. This is slow and raises privacy concerns.
Our compressor uses browser-based logic (Canvas/WASM). Your 20MB raw photo is compressed right here on your laptop. It's faster, saves bandwidth, and is perfectly private.
