How to resize an image
- Add your photos. Drop them on the box, choose them from your device, or paste with Ctrl+V. You can add as many as you like.
- Choose how to resize. Type a width or height, scale by a percentage, or pick a preset such as Instagram post.
- Download. Each photo shows its new size in pixels. Download them one by one or all together as a zip.
Pixels, percent or preset
Pixels sets an exact width or height. With proportions kept, each photo in a batch keeps its own shape, so a portrait and a landscape photo both come out 1200 px wide without being squashed. Untick it to force both sides, which stretches photos of a different shape. Switch the unit to cm or inches to size for print at a chosen DPI.
Percent scales every photo by the same amount. 50% halves both sides, which leaves a quarter of the pixels and usually a file around a quarter of the size.
Presets give the exact sizes social sites recommend. Crop to fill trims the edges from the centre so the result is exactly the preset size. Fit inside keeps the whole photo; tick the borders option to pad it to the exact size with a colour of your choice.

Tips for sharp results
Shrinking a large phone photo by a lot is done in halving steps, which keeps fine detail such as hair and text crisp instead of jagged. Enlarging is allowed, but each row warns you when a photo is being made bigger than the original.
For a size limit in KB rather than pixels, use the image compressor after resizing. To keep a see-through background, save as PNG or WebP; JPG fills transparent areas with the colour you pick.
Frequently asked questions
Are my photos uploaded?
No. Resizing happens inside your browser with its built-in image engine. The files never leave your device, and the page keeps working if you go offline after it loads.
How do I resize without stretching the photo?
Keep "Keep proportions" ticked and type only the width or the height; the other side follows the photo's shape. With a preset, choose Crop to fill to trim the edges or Fit inside to keep the whole picture.
Can I make a small image bigger?
Yes, but enlarging can't add detail that wasn't captured, so the result looks softer. The tool tells you when a photo is being enlarged and by how much. For printing, start from the original full-size photo if you have it.
What does resizing to centimetres or inches mean?
Screens only know pixels, so a physical size needs a resolution. At 300 pixels per inch, a 10 × 15 cm print needs 1181 × 1772 px. Pick cm or in, set the DPI your printer or form asks for, and the tool works out the pixels.
Does resizing keep the photo's location and camera details?
No. The new file contains only the picture, not the EXIF data such as GPS location, camera model or date. That's useful before sharing photos publicly.
