Quality resizing
Sharpness preserved
Downscaling happens in steps with high-quality smoothing to avoid a jagged look.
Proportions respected
The image fits within the desired dimensions without being distorted.
Format change
Save the result as JPG, PNG, or WebP depending on your needs.
Batch processing
Resize dozens of images to the same dimensions at once.
Change an image's size in pixels
Social networks, sales sites, résumés, and forms often require exact dimensions: 1080 × 1080 pixels for Instagram, 400 × 400 for a profile picture, 1920 pixels wide for a website. Enter the desired width and height: with “Keep proportions”, the image is adjusted without being distorted.
Resize by percentage
To quickly shrink a series of photos, choose a percentage: 50% halves the width and height, and cuts the file size by roughly four. You can also enlarge up to 200%, with an inevitable loss of sharpness for very small images.
Resize with no software to install
No need for Photoshop or Paint: resizing happens in your browser, on computer or mobile, and your images are never uploaded.
Frequently Asked Questions
Does resizing reduce the image's file size?
Yes: fewer pixels means a lighter file. To reduce the size further without changing the dimensions, use the “Compress Image” tool.
Will my image get distorted?
No, if “Keep proportions” is checked: the image fits within the chosen width and height without stretching.
Can I enlarge an image?
Yes, up to 200%. Note: enlarging a small image doesn't create detail, it will look somewhat blurry.
What size for Instagram?
1080 × 1080 pixels for a square post, 1080 × 1350 for a portrait, and 1080 × 1920 for a story.
