About the Image Resizer
Resize photos to the exact dimensions a website, passport form or social network asks for. Set a width and height in pixels or scale by a percentage; the aspect ratio is kept so your image is never stretched.
How to use it
- Add one or more images.
- Choose to resize by maximum pixels or by percentage.
- Download the resized images individually or as a ZIP.
Fit within a box, never stretched
Choose ‘Max px’ to fit each image inside a width and height while keeping its proportions. A 4000 × 3000 photo resized to fit 1200 × 1200 becomes 1200 × 900. Choose ‘%’ to scale by a percentage instead; 50% halves both sides and typically cuts the file size by around three quarters.
Common sizes
Website images usually need 1200–1920 px across. Instagram posts are 1080 px wide, Facebook and LinkedIn link images are 1200 × 630 px, and email signatures look best under 600 px wide. Passport and ID photo portals often state exact pixel dimensions; set both boxes to those values.
Quality tips
Shrinking an image keeps it sharp, but enlarging cannot add detail that wasn't captured, so upscaled images may look soft. Resize first, then compress, for the smallest files. Everything happens in your browser, so private photos stay on your device.
Frequently asked questions
Will my image be stretched?
No. The image is scaled to fit within the width and height you set while keeping its original proportions.
Can I make an image larger?
Yes, but enlarging cannot add detail, so the result may look soft.
Is there a file limit?
There is no fixed limit. Very large images use more memory, so older phones may be slower.
