Image Compressor
Compress JPG, PNG or WebP images, choose output format and quality, and optionally resize large images.
Why use this image compressor?
Use the image compressor to reduce photo and graphic file sizes before emailing, uploading to a website or sharing online. You can choose JPEG, WebP or PNG output, control quality and limit oversized images to a practical width.
Example
A 5 MB phone photo can be resized to 1920 px wide and exported as WebP or JPEG, often reducing transfer size substantially while keeping useful visual quality.
Important note
Compression is lossy for JPEG and WebP. PNG is better for graphics that need transparency. Always inspect the downloaded image before deleting the original.
How to use it
Start with the inputs shown above, review the assumptions or options, then generate the result. Where the tool creates a file, keep the original until you have opened and checked the downloaded output.
