How to compress an image online
- Drop the image you want to make smaller, or choose it from your device.
- Choose JPEG or WebP for the strongest compression, then lower quality until the preview still looks good.
- Compare the original and compressed sizes, then download the lighter file.
Tips for smaller image files
JPEG and WebP usually beat PNG for photographs. If the image is also very wide or tall, resize it first and then compress. Need a different format afterward? Convert the image to JPG, PNG, or WebP.
Frequently asked questions
What quality setting should I use?
Start around 70–85% for web photos. Lower the quality further only if you still need a smaller file and the preview remains acceptable.
Is WebP better than JPEG for compression?
WebP often produces a smaller file at a similar visual quality, especially for websites. JPEG remains the most compatible choice for older systems and many email clients.
Does image compression happen on my device?
Yes. This compressor runs in your browser, so the image does not need to be uploaded for standard compression.
