How much can I compress a JPG without losing quality?

JPEG quality of 75–85% is typically indistinguishable from the original on screen. Below 60%, compression artifacts become visible in areas of fine detail and smooth gradients.

What is JPEG quality and how does it work?

JPEG uses lossy compression. Quality % controls how much detail is discarded. Higher quality = larger file size. Lower quality = smaller file with more artifacts. Quality 80% is a widely accepted web standard.

Does FixTools keep the compressed image as JPG?

Yes. The compressed output is saved as a JPEG (.jpg) file.

Can I compress multiple JPG files at once?

Use the batch compress feature to upload and compress multiple JPGs simultaneously.

Is there a limit to how many JPGs I can compress?

No. FixTools is completely free with no usage limits.

What is the difference between JPG and JPEG?

JPG and JPEG are the same format. JPG is the shortened file extension used on older Windows systems (which required 3-letter extensions). They are interchangeable.

Can I compress a JPG on my phone?

Yes. FixTools works in mobile browsers on both iPhone and Android. No app download is needed.
