What the Image Compressor does
Make JPG, PNG and WebP images smaller for faster websites, email attachments and upload limits. The compressor re-encodes each image at the quality you choose and can also limit the longest side, which is often the biggest saving for photos straight from a phone camera.
Options
- Output format: JPG for maximum compatibility or WebP for smaller files with transparency.
- Quality (10–100); 70–80 is a good balance for photos.
- Limit longest side to shrink oversized photos at the same time.
Good to know
Already heavily compressed images may not get smaller; the result shows the new size so you can compare.
