Biggest savings
- Photos straight from a phone are often 3-6 MB; at 80% quality they drop to a fraction of that.

Frequently Asked Questions
How do I compress an image?
Choose or drop your images and move the quality slider. Each file shows its old and new size, so you can find the smallest size that still looks good. Download one by one or as a ZIP.
What quality should I use?
75-85% is usually invisible to the eye and cuts photos by half or more. Go lower for thumbnails; stay higher for printing.
Can I compress PNG files?
PNG is lossless, so the real savings come from saving as JPG (no transparency) or WebP (keeps transparency, very small).
I need an exact size like 100 KB. Which tool?
Use resize image in KB: you type the limit and it finds the best quality that fits automatically.
Are my images uploaded?
No. Compression runs in your browser.
