Compress Image

How to compress an image

1. Drop your image on the box above, or click to choose it.
2. Pick JPEG or WebP for the output.
3. Move the quality slider until the size looks right.
4. Press Download to save the smaller image.

JPEG or WebP

The tool lets you pick the output format. JPEG works everywhere and is the safe choice for uploads and sharing. WebP makes smaller files at the same quality and is great for websites, but a few older programs cannot open it. If you are not sure, start with JPEG.

How quality affects size

The slider trades quality for size. Near the top, the image looks the same but the file shrinks a little. In the middle, the file drops a lot while still looking good on a screen. Down low, you get a tiny file with visible blur. A quality around 60 to 80 is a good balance for most photos.

When compression helps

Use it when a photo is too big to email, too heavy for a web page, or over an upload limit. Compression keeps the same width and height but stores the picture with less data. For a strict size target, try the tools that compress to a set number of kilobytes.

FAQ

Which format makes the smallest file?

WebP is usually smaller than JPEG at the same quality. JPEG is more widely supported. Pick based on where the image will go.

Does compressing change the image size on screen?

No. The width and height stay the same. Only the file size drops. To change the pixel size, use the resize tool.

What quality should I choose?

For most photos, 60 to 80 keeps them looking good while cutting the file a lot. Go higher for prints and lower for quick web use.

Can I compress a PNG here?

You can load a PNG, but it will be saved as JPEG or WebP. To keep it a PNG, use the compress PNG tool.

Are my images private?

Yes. Compression runs in your browser. Nothing is uploaded or saved.

Is this the same as an image size reducer?

Yes. An image compressor and an image size reducer do the same job: both reduce image file size by storing the picture with less data. This page also works as a photo compressor, since photos are where JPEG saves the most.

Can I make an image smaller without losing quality?

At quality 80 and above, most people cannot see any change, so you can reduce image size a long way without losing quality you would notice. To make an image smaller in a stronger way, lower the quality further and watch the preview until it stops looking good.
