How to resize an Image:
1. Add your image. Drag a photo onto the box, tap it to choose a file from your device, or paste an image from your clipboard.
2. Choose how to set the new size.
- Percentage (%): Enter how much smaller you want the image. For example, 50% makes it half its original width and height.
- Dimensions (px): Type an exact width and height in pixels. Leave "Keep aspect ratio" checked so the photo isn't stretched.
3. Pick a format. JPG is best for photos, PNG keeps sharp edges and transparency, and WebP gives small files for websites.
4. Set the quality. For JPG and WebP, a lower quality makes a smaller file. Around 80-85% is a good balance.
5. Click "Resize image" to see a preview and the new file size.
6. Click "Download" to save the resized image to your device.
Image Resizing Tips:
- Making an image smaller in pixels is the quickest way to shrink its file size.
- For websites and blogs, a width of 1200-1920 px is plenty for most photos.
- For email, try 800-1280 px wide.
- Your original file is never changed. The resized copy is saved as a new file.
Frequently Asked Questions:
Are my photos uploaded anywhere?
No. Resizing happens entirely in your browser, so your photos never leave your device.
Is this image resizer free?
Yes. There's no sign-up, no watermark, and no limit on how many images you resize.
Why won't my iPhone photo open?
Most browsers can't read HEIC files. Convert the photo to JPG first, or set your iPhone's camera to "Most Compatible" under Settings > Camera > Formats.
What is the largest size I can make an image?
Up to 16,000 pixels on each side, though very large images may be slow on older phones.
Which format should I choose?
Use JPG for photos, PNG for graphics, logos and screenshots, and WebP when you want the smallest file for a website.
