Frequently asked questions
How do I convert HEIC to JPG?
Add your HEIC photo, keep JPG selected and press Convert & Download. The photo is converted in your browser, with no upload.
What happens to transparency when converting PNG to JPG?
JPG cannot be transparent, so empty areas become white. Keep PNG or choose WebP if you need transparency.
What is ICO used for?
ICO is the favicon format for websites and some Windows icons. Files are limited to 256 pixels on the longest side, so larger images are scaled down.
Should I use WebP or JPG?
WebP files are usually smaller and support transparency. JPG is accepted by the widest range of apps and sites.
Is it free?
Yes. It is free to use, with no sign-up and no watermark.
Are my photos uploaded anywhere?
No. HD Resizer runs entirely in your browser, so your images stay on your device. Nothing is sent to a server, and there is no account or watermark.
