Frequently asked questions

Short answers to the things people ask most about converting and compressing images.

Is this image converter free?
Yes. PicConverter is a completely free image converter and image compressor — no watermarks, no subscription, and no account required.
How do I convert JPG to PNG?
Open PicConverter, select your JPG, choose PNG as the output format, and export. You can convert a single image or a whole batch at once, in either direction.
Can I convert HEIC to JPG?
Yes. PicConverter turns HEIC iPhone photos into JPG or PNG so they open on any device.
Does compressing reduce image quality?
You choose the balance. Compress hard for the smallest file or keep quality high — the app shows you the size saved before you export.
