How to resize an image
- Add your images (JPG, PNG, WEBP, HEIC…).
- Choose a percent, a width, a height or a ready-made size.
- Click Resize and download the result.
Websites, social networks and online forms often ask for an exact size: 1080×1080 for an Instagram post, 1200×630 for a Facebook link preview, 400×400 for a profile picture, or a 35×45 mm passport photo. This tool applies those sizes with nothing to install.
Scale by percent (50% halves both sides), set just the width or the height and keep the proportions, or force an exact width and height. When your picture's shape doesn't match the target, either keep the whole picture with white, black or transparent borders, or fill the frame by cropping the edges.
Small pictures are not enlarged by default, because upscaling makes them blurry — tick the option if you really need it. The passport preset gives a 413×531-pixel image, suited to a 35×45 mm print at 300 DPI; always check the exact rules of the office that asks for it.
You can resize up to 50 images at once. Files are processed in memory and deleted automatically after 30 minutes.
Frequently asked questions
How do I resize an image to an exact size in pixels?
Upload the image, type the width or height in pixels (the other side follows to keep the proportions, unless you unlock it), or pick a percentage or a preset such as Instagram or passport size, then download.
How do I resize a photo for Instagram?
Choose “Ready-made size”, then “Instagram square” (1080×1080) or “Instagram portrait” (1080×1350). Keep the white-borders option to show the whole photo.
Will my picture be stretched?
No. Proportions are always kept: the tool adds borders or crops the edges, as you choose, and never stretches the image.
Can I make a small picture bigger?
Yes, tick “Allow enlarging small pictures”. Bear in mind that an enlarged image looks less sharp.
Can I resize many photos at once?
Yes, up to 50 images with the same settings, free and without an account.
Does it work on my phone?
Yes, it runs in your phone's browser just like on a computer, including iPhone HEIC photos.
