HD Resizer is a free set of image tools: resize, crop, compress, convert, rotate, turn pictures into PDF, and make app icons and store screenshots. Everything runs in your web browser.
Private by design
When you add a picture, it is opened and changed on your own device. It is not uploaded to a server, so we never see it and cannot keep a copy. That also makes the tools fast, because there is no waiting for an upload.
What it can do
- Resize to exact pixels, a percentage, or ready-made sizes up to 8K, with drag and zoom to frame the picture.
- Compress to a quality or a maximum file size in KB.
- Convert between JPG, PNG, WebP and ICO, and open iPhone HEIC photos.
- Create PDFs from one or many images.
- Generate iOS and Android app icon sets and App Store or Google Play screenshot sizes.
Good to know
Making a small picture much bigger cannot add detail that was never there, so large enlargements look soft. Very large sizes may not work on phones, which have less memory than computers.
