Image Compress — Shrink Photos Without Visible Quality Loss
Compress a JPG, PNG or WebP image and cut its file size, often by 50-80%, with quality still good enough for web, email or messaging. The quality slider lets you find the sweet spot for your image.
Quality vs. size trade-off
At 90% quality the image looks identical but savings are small. 70-80% is the web sweet spot — huge size reduction, no visible degradation on photos. Below 50%, JPG artifacts start to show around edges.
Format matters
Photos compress best as JPG. Screenshots and line art compress best as PNG — JPG artifacts around text look terrible. For a modern balance, output WebP.
Frequently Asked Questions
Why is my PNG barely smaller after compression?
PNG is already lossless-compressed. To get big savings, convert screenshots of photos to JPG or WebP instead.
Does compression lose the image forever?
The output is compressed; your original stays on your device untouched.
Can I compress many images at once?
Yes — use the Batch Image Compress tool for that.
