Reduce Image Size (KB/MB)
Reduce file size by compressing or converting images — right in your browser.
How to Reduce Image Size (KB/MB)
- Upload your image (or add multiple files).
- Adjust quality or switch output format (WebP often saves more).
- Download the optimized image(s).
Reduce file size without uploading
If you’re trying to hit a specific upload limit (for example 200 KB, 500 KB, or a few MB), compression is usually the fastest option. This tool runs on your device in the browser, so you can optimize images quickly and keep your files private.
Two ways to shrink images
You can reduce size by lowering quality (best for photos) and by converting formats. WebP often gives the best savings, while JPG is widely used for photos and PNG is ideal for graphics and transparency.
How to choose settings
Start at ~70–85% and compare the preview. If the result is still too large, lower the quality gradually. If you need better quality at a smaller size, try switching the output format to WebP.
Batch optimize multiple images
Add multiple files and use “Download All” to export the optimized versions. This is helpful when preparing galleries, product photos, or social media assets.
