About the Image Compressor
Compress images free without uploading them anywhere. Drop in a JPG, PNG, or WebP, adjust the quality slider, and watch the file size shrink — often 60–90% smaller for photos — while comparing before/after sizes live. Smaller images mean faster pages, better Core Web Vitals, and emails that actually send. Because compression runs in your browser, private photos stay private.
How to use the Image Compressor
- 01Upload or drop an image.
- 02Pick an output format and adjust the quality slider.
- 03Compare the original and compressed file sizes.
- 04Download the smaller image.
Frequently asked questions
Are my images uploaded to a server?
No. Compression happens entirely in your browser using Canvas — your images never leave your device.
Which format gives the smallest file?
JPG and WebP compress photos far smaller than PNG. WebP usually wins on size at the same quality; PNG is best for graphics needing transparency.
How do I compress an image to 100KB?
Lower the quality slider until the shown output size dips under 100 KB — for large photos, converting to WebP or JPG first gets you most of the way.
