Which tool should you use?
- A form or site wants exact pixels, like 600 × 600: Bulk Image Resizer.
- The file is too heavy for email or an upload limit: Compress Image lowers the file size while keeping the same dimensions.
- You need a different format, like PNG to JPG or WebP: JPG PNG WebP Converter.
- You want bold text on a picture: Meme Generator.
Typical workflows
Resizing and compressing solve different problems. Resizing changes the number of pixels; compressing keeps the pixels but stores them more efficiently. A 4000-pixel phone photo going on a website usually needs both: resize it to the width it will be shown at, then compress. Converting a screenshot from PNG to JPG is often the quickest win of all, because PNG stores photos inefficiently.
Pictures are decoded and re-encoded by your browser on your own device, so private photos and ID scans stay with you.
Frequently asked questions
Is the location data in my photos kept?
Resizing and converting write a brand-new file without the original EXIF data, including GPS location. Compressing does the same, unless it can’t make the file smaller; then your original is kept unchanged.
Can I open HEIC photos from an iPhone?
Only in browsers that can display HEIC, such as Safari. In other browsers, set the iPhone camera to “Most Compatible” to save JPG instead.
