Image Compressor
Drop in a JPG, PNG or WebP image and shrink it right here. Everything runs on your device — nothing is uploaded.
Free online image compressor
Large images slow down websites, fill up inboxes and eat through storage. This compressor redraws your picture and re-encodes it at the quality you choose, letting you cut file size dramatically while keeping it looking good. Slide the quality control, switch between JPEG, WebP and PNG, and watch the savings update instantly before you download.
Your images never leave your device
Unlike most online compressors, this tool does all the work directly in your browser using the Canvas API. Your image is never uploaded to a server or stored anywhere — close the tab and it's gone.
Frequently asked questions
Are my images uploaded anywhere?
No. Compression happens entirely inside your browser on your own device. Nothing is sent to a server, so even private or sensitive images stay with you.
Which format should I choose?
JPEG is best for photos, WebP usually gives the smallest files at the same quality, and PNG keeps lossless quality but larger sizes. The quality slider affects JPEG and WebP; PNG ignores it.
Why did my file get bigger?
Re-encoding an already highly compressed image, or converting to PNG, can increase size. Try a lower quality setting or switch to WebP for the smallest result.
