About the Image Resizer
Websites, job portals, social networks and email often reject images that are too large. This image resizer lets you set an exact width in pixels — with the height adjusted automatically to keep proportions — or scale the whole image by a percentage. Processing happens on your device using the browser’s built-in canvas, so even private photos and ID scans never leave your computer or phone.
How to use the Image Resizer
- Drag an image onto the box or click "Choose image". JPG, PNG, WebP, GIF and BMP are supported.
- Choose "By pixels" and enter a new width, or "By percentage" and enter a scale such as 50%.
- Keep "Keep aspect ratio" ticked to avoid stretching the picture.
- Click "Resize image", check the preview and the new file size, then download.
Common image sizes
Typical recommended dimensions (platforms change these occasionally):
- Instagram square post: 1080 × 1080 px.
- Full HD screen or YouTube thumbnail width: 1920 px / 1280 × 720 px.
- Website hero image: usually 1600–2000 px wide.
- Email attachments: 1200 px wide is plenty for viewing on screen.
Making images bigger
Enlarging an image cannot add detail that was not captured in the original — it only stretches the existing pixels, so the result looks softer. For best quality, start from the largest original you have and make it smaller.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser on your own device. Your files are never uploaded, so nobody else can see them, and nothing is kept after you close the page.
Will resizing reduce the quality?
Making an image smaller keeps it sharp. Choosing JPG or WebP with a quality of 85–90% is visually lossless for most photos.
Does it keep the photo’s EXIF data?
No. The browser redraws the image, so camera details and GPS location are removed. This is usually good for privacy.
Can I resize a GIF animation?
Only the first frame is kept. Animated GIFs are saved as a still image.
