What is the Image Compressor?

A browser-based image compressor that reduces file size by applying JPEG compression to your image. Adjust the quality slider to balance file size against visual quality. A before-and-after comparison shows exactly how much space you have saved. No upload required — all compression happens locally.

When would you use it?

Speeding up your website

Large image files are one of the main causes of slow page load times. Compress images before uploading them to your website to improve performance and SEO.

Reducing email attachment size

Compress a photo before attaching it to an email — most email providers have attachment size limits and large images cause problems.

Saving storage space

Compress a batch of photos before archiving them to save disk space without noticeably affecting visual quality.

Preparing images for social media

Compressed images upload faster and reduce data usage for mobile users viewing your posts.
