FAQ
Frequently asked questions
How much smaller will my images get?
Photos usually shrink 50–80% and PNG graphics 60–90%. If a file is already optimal, Aimg keeps the original rather than making it bigger.
Does compressing remove EXIF and GPS data?
Yes. Re-encoding strips metadata such as GPS location and camera details, after applying the correct orientation.
Can I compress PNG without losing transparency?
Yes. PNGs are converted to an optimized palette PNG that keeps full alpha transparency.
Is Compress image on Aimg free?
Yes — completely free with no limits, no sign-up and no watermark. Your images are processed in your browser and never uploaded.
