How to resize an image online in 4 steps
- Add your pictures. Drop them into the box above, or click it and pick files. You can add many at once.
- Choose a size. Tap a preset (like Blog cover or Pinterest), or type your own width and height in pixels. A pixel is one tiny dot of a picture — more pixels means a bigger, sharper image.
- Choose how it fits. Cover fills the whole size and trims the edges, Contain keeps the whole picture and fills the gaps with a background colour, and Stretch squeezes it to match exactly.
- Pick a format and press Resize. Your files are saved to your computer. If you resized several, they arrive together in one ZIP file.
Which format should you pick: JPEG, PNG or WebP?
- JPEG — best for photos. Small files that work everywhere.
- PNG — best for screenshots, logos and sharp text. Files are bigger, but nothing gets blurred.
- WebP — a newer format that makes files smaller than JPEG or PNG. Every modern browser can open it.
Only need to change the file type and keep the size? Use the Image Converter instead.

Questions people ask
Is this image resizer really free?
Yes. There is no account, no watermark and no daily limit. Open the page, drop your pictures in and resize.
Are my pictures uploaded anywhere?
No. The resizing happens inside your own browser, on your own computer. Your pictures never leave your device, so it is safe to use with private photos.
Will resizing make my picture blurry?
Making a picture smaller keeps it sharp. Making it bigger is different: the browser has to invent the extra pixels, so a small picture stretched very large can look soft. If you can, always start from your biggest original.
Can I resize many images at once?
Yes. Add as many pictures as you like, choose one size, and they are all resized in one go and downloaded together as a ZIP file.
What is the difference between resizing and compressing?
Resizing changes how many pixels a picture has (its width and height). Compressing makes the file smaller without changing those numbers. Saving a resized picture as JPEG or WebP usually makes the file smaller too.
