PNG, JPG, WebP · multiple files · up to 25MB each
Lower quality means smaller files. Settings apply to images compressed after you change them.
How to compress images online
Upload one or more images, pick an output format, and drag the quality slider until the size and look are right. Each file shows its before-and-after size and how much smaller it got, then you can download the optimized version.
Smaller images load faster, which improves user experience, SEO, and Core Web Vitals. Because everything runs locally in your browser, even large batches stay completely private.
Frequently asked questions
How much smaller will my images get?
It depends on the source and quality setting, but photos often shrink by 50–80% with little visible difference. Each result shows the exact before-and-after size so you can find the right balance.
Which format should I choose?
Choose JPG for maximum compatibility, or WebP for the smallest files. WebP typically compresses better than JPG at the same quality.
Does compressing reduce quality?
Lossy compression removes some detail, but at moderate-to-high quality the difference is usually imperceptible while the file gets much smaller. Use the slider to tune it to your needs.
Are my images uploaded anywhere?
No. All compression happens locally in your browser — your files never leave your device, so it's safe for private or sensitive images.
