Resize image
Make pictures the width a website, a profile or a form asks for. Pick a width or type one; every image in the list gets it, the height follows the shape, and nothing leaves your device.
How to resize an image
- Pick the width: 1920, 1280, 800 or 400 pixels, or choose "width…" and type the pixels you need.
- Drop your images on the box, or click it to choose them. Each one is resized as it is added; the row shows the new pixel size.
- Save the images one by one, or all of them in a single ZIP file.
Questions
Are my files uploaded anywhere?
No. The conversion runs inside your browser, on your own computer or phone. Your files are never sent to a server, so nobody else can see them.
Is there a limit on how many files I can convert?
No daily limit and no sign-up. Drop as many files as you like; the only limit is your device's memory, so very large batches simply take longer.
Can I set the height too, or an exact size?
The height follows the picture's shape, so nothing is squashed. An exact width and height, like a square profile picture, needs cropping: use Crop image, which takes both.
Can a small picture be made bigger?
No. Enlarging adds no detail, it only blurs, so a picture already narrower than the width is kept as it is.
Which format do I get back?
The one you put in: a JPG stays JPG, a PNG stays PNG, a WebP stays WebP. iPhone HEIC photos come back as JPG, and GIF, BMP, AVIF and SVG files as PNG, because browsers can't write those formats.
Is the quality kept?
A PNG keeps every pixel. A JPG is saved again at high quality, so the change is hard to see, and its date taken and camera details are kept in the file.
