Free Image Compressor

Need an image under an upload limit without making it look awful? Add your file, adjust the quality, preview the size change, and download a lighter version that still looks good.

Use the tool

Compress an image without ruining it

Start with moderate quality, compare the preview with the original, and lower it only until the file fits your real size limit.

Use the tool

Choose the source image

Upload a supported JPG, PNG, WebP, BMP, or AVIF file within the displayed size limits.

Set dimensions if needed

Enter a smaller width or height when the original contains more pixels than the destination can show.

Adjust format and quality

Preview a sensible output format and lower quality in small steps rather than making one extreme change.

Compare and download

Check dimensions, file size, and visible detail before saving the compressed copy.

Image compression examples for common uploads

The right settings depend on whether the image is a photograph, graphic, screenshot, or transparent asset.

Website photograph

Resize a 4,000-pixel camera image closer to its display width, then export as WebP or JPG at a balanced quality.

Transparent graphic

Keep PNG or choose a format that supports transparency when the background must remain clear.

Email attachment

Reduce both dimensions and quality until the file fits the attachment target while text and faces remain readable.

Choose the smallest file that still looks right

Resize before heavy compression

Removing pixels the destination cannot display often saves more space with less visible damage.

Photographs and graphics differ

Photos usually tolerate JPG or WebP compression, while logos and sharp interface captures may need different settings.

A result can be larger

Changing formats or using very high quality can produce a file larger than the source, and the comparison will say so.
