What is a JPG Compressor?
A JPG compressor re-encodes a JPG photo at a lower quality setting to shrink its file size — JPG is already a compressed format, so a dedicated compressor squeezes further savings out of it in a controlled way, rather than a generic re-save. This is the tool to use when your JPGs need to hit a specific size limit for email, upload forms, or web pages, without noticeably harming how the photo looks.

Frequently Asked Questions
What's the difference between Compress JPG and Compress JPEG?▾
Nothing technically — JPG and JPEG are the same format with different file extensions. Both pages use the same compressor.
How much smaller will my JPG get?▾
It depends on the image and your chosen quality — photos with lots of detail typically compress less than simpler images at the same setting.
Can I batch-compress JPGs?▾
Yes, up to 20 at a time, each with its own result and download link, plus a "Download All as ZIP" option.
