Compress Image Online Free
Reduce image file size without losing quality. Adjustable compression levels from 1-100. Convert to WebP for even smaller files.
How to Compress Images
After uploading, add quality parameter to the image URL. Lower quality = smaller file size. Our compression uses smart algorithms to maintain visual quality while reducing file size.
Quality Level Guide
Best Quality
q_90 to q_100
Minimal compression. Best for printing or when quality is critical. ~10-20% size reduction.
Balanced
q_70 to q_85
Recommended for web. Good visual quality with significant size reduction. ~40-60% smaller.
Max Compression
q_40 to q_60
Maximum compression. Some quality loss visible. Good for thumbnails. ~70-80% smaller.
Compression Parameters
| Parameter | Description | Example |
|---|---|---|
q_ | Quality level 1-100 (default: 80) | q_70 |
f_webp | Convert to WebP for 25-35% smaller files | q_70,f_webp |
fl_progressive | Progressive JPEG (loads gradually) | q_70,fl_progressive |
w_ | Resize width (smaller = smaller file) | q_70,w_1200 |
Tips for Maximum Compression
- Use WebP format - Add
f_webpfor 25-35% smaller files with same quality - Resize large images - A 4000px image resized to 1200px is much smaller
- Combine parameters - Use
q_70,w_1200,f_webpfor maximum reduction - Test different levels - Start at q_70, go lower if file size still too big
Frequently Asked Questions
Typically 40-80% reduction depending on settings. Using q_70 usually gives 50% reduction. Adding WebP conversion can reduce another 25-35%.
Quality levels above 70 are virtually indistinguishable from the original for most images. Below 50, some artifacts may be visible, especially in gradients and fine details.
WebP offers the best compression for web. It's supported by all modern browsers. Use f_webp for photos. For images with transparency, WebP or PNG work well.
Maximum upload size is 50MB. After compression, there's no minimum - you can compress to any size using quality and resize parameters.
