JPG Compressor

JPG Compressor is focused on JPEG sources such as camera photos, exported photographs, scanned images, and other continuous-tone pictures where lossy compression is already part of the format. The current workflow keeps width and height unchanged, so the main decision is how aggressively to re-encode the image. This is useful when a photo looks correct but is too large for email, a website, an application form, or a document attachment.

Low, Medium, and High compression move progressively toward smaller output with a greater chance of visible artifacts. Fine texture, hair, text inside a photograph, gradients, and repeated edges can reveal stronger JPEG compression before broad smooth areas do. Use No compression only when the rest of the settings mean the original can remain unchanged. The optional Target KB field can guide the encoder toward a size goal, but not every photograph can reach every target without reducing dimensions.

The output format can stay aligned with the source or be changed to JPG, WebP, or PNG when the destination allows it. Choosing PNG for a photograph may increase file size because it changes the compression model rather than magically improving the source. WebP may be useful when modern web delivery is acceptable; explicit JPG is better when the recipient requires JPEG compatibility.

Compression happens in the browser. Use Compress Image Under 100KB or 200KB when a named upload limit is the main constraint. Use Image Resizer when reducing pixel dimensions is permitted and a substantially smaller photo is more important than preserving the original canvas.
