Frequently asked questions
Is this converter free?
Yes, it is completely free. There is no signup, no watermark, and no limit on how many files you can convert.
Are my files uploaded to a server?
No. Smart Convert Pro runs entirely in your browser. Files are converted on your own device and never uploaded, so nothing is stored on a server or seen by anyone else.
What's the maximum file size?
Each image can be up to 25 MB. You can add multiple files to the queue and convert them in a single batch.
Does converting PNG to HEIC reduce quality?
The converter keeps the full resolution of your image. Any quality difference depends only on the nature of the HEIC format itself, not on the tool.
