What is an Image Compressor?
An image compressor reduces an image’s file size — often significantly — while keeping visual quality close to the original. This is essential for website performance, since smaller images load faster, improve Core Web Vitals scores, and reduce bandwidth usage.
How to Use the Image Compressor
- Upload or drag and drop your image.
- Adjust the quality slider — lower values mean smaller files but more visible compression artifacts.
- Optionally set a maximum width to downscale large images (this often saves more space than quality reduction alone).
- Choose an output format, or keep the original, then click “Compress & Download.”
FAQs
How much can I reduce my image size without noticeable quality loss?
Most photos compress well at a quality setting of 0.6–0.8 with minimal visible difference. The biggest single factor in file size, though, is usually image dimensions — resizing a 4000px-wide photo down to 1920px (typical max display width) often reduces file size more than quality adjustment alone.
What’s the difference between this and the Image Converter tool?
The Image Converter focuses on changing file format (PNG ↔ JPG ↔ WebP). This Image Compressor focuses specifically on reducing file size through quality and dimension adjustments, and shows you exactly how much space you saved.
Why does my PNG not compress much even at low quality?
PNG is a lossless format — the quality slider has less effect on PNG files. For maximum size reduction on photos, converting to JPG or WebP alongside compression usually gives much better results than staying in PNG.
Does compressing an image affect its dimensions?
Only if you set a max width — otherwise dimensions stay the same and only file size (via compression quality) changes.
