Free Image Resizer

Yes. There is no account, no email, no watermark and no cap on how many images you resize. Use it for personal or commercial work as much as you like.

No. This is the main difference from most online resizers. Your image is decoded, resized and re-encoded inside your browser, on your own device. The file never leaves your computer or phone, which makes it safe for private photos, IDs and confidential images.

Pick the Pixels method, then type the width and height you need. If the lock is on, the height updates to keep the shape when you change the width, so the image is never stretched. Turn the lock off if you want to set both sides freely, and choose how it fills the new shape.

Leave the lock switched on. When you change one side, the other updates in proportion, so the image keeps its shape and nothing looks squashed. This is the default. If you deliberately want a different shape, turn the lock off and the fit options let you decide what happens to the extra space.

These decide what happens when the new size is a different shape from your image. Fit puts the whole image inside the new size and pads the gaps with a background colour. Fill scales the image up so it covers the whole size and crops the overflow. Stretch forces the image to the exact box, which can distort it. Fill is the usual choice for social media.

Yes. Choose the File size method and type a target in KB. The tool saves as JPG or WebP and searches for the quality that lands at or under your limit. If it still cannot get there at the lowest quality, it gently reduces the dimensions until it fits. It is handy for upload forms and email attachments that cap the size.

There are ready-made presets for social media (Instagram, Facebook, X, LinkedIn, Pinterest, YouTube and profile photos), for screens (HD, Full HD, 2K, 4K and favicons) and for print at 300 DPI (4 × 6, 5 × 7, 8 × 10, A4 and A5). Pick one and the width and height are filled in for you.

You can enlarge an image, but it cannot add detail that was not captured. Scaling up spreads the same pixels over a bigger area, so the result looks softer the more you push it. For a sharp large image you need a photo that already has enough pixels. Resizing down, on the other hand, keeps things crisp.

You can bring in JPG, PNG, WebP, GIF and BMP, and save as PNG, JPG or WebP, or keep the original format. PNG stays lossless and keeps transparency. JPG and WebP are smaller for photos, with a quality dial. When you save a transparent image as JPG, the see-through areas are filled with a background colour you choose.

Making an image smaller keeps it looking sharp and cuts the file size. The only quality loss comes from the format you save in: JPG and WebP trade a little detail for much smaller files, which you control with the quality slider. PNG is lossless, so it keeps every pixel but the files are larger.

No. It runs in any modern browser on a phone, tablet or computer. There is nothing to download or install, and it works the same on Windows, mac, Linux, Android and iOS.
