Reduce an image's file size by re-encoding it as a JPEG at a quality level you choose — lower quality means a smaller file, at the cost of some visual detail. Processing happens locally on the HTML5 canvas, so images aren't uploaded anywhere. Select multiple images and AiFileStudio batches them into a ZIP.
A quality around 60-80 is usually a reasonable balance between file size and visual quality for photos; go lower if file size matters more than appearance.
Frequently Asked Questions
Does this resize my image too?
No — dimensions stay the same; only the compression quality changes. Use the Resize Image tool if you also want to change dimensions.
What quality setting should I use?
60-80 is a reasonable starting point for photos. Go lower for maximum size reduction if some quality loss is acceptable.
