Image Resizer Free — Resize & Crop Photos Online
Every website, social network and form seems to want a different photo size, and a picture that looks perfect on your phone can be rejected for being too large, too small or the wrong shape. This free image resizer fixes that in seconds, right in your browser. Upload a photo, type the exact width and height you need in pixels, and download the resized result as a PNG, JPG or WebP file. You can lock the aspect ratio so the picture never looks stretched, pick a ready-made preset for Instagram, YouTube, LinkedIn, Facebook or X, or crop the photo to fill the frame exactly. Your file stays in your browser the whole time: nothing is uploaded to a server, nothing is stored, and there is no account, no watermark and no limit on how many images you resize.

How to Use
- Upload your image. Click the drop zone and choose a JPG, PNG, WebP or GIF file, or drag the file straight into the box. The original size in pixels appears below the box.
- Choose a size. Pick a preset for Instagram, YouTube, LinkedIn, Facebook or X, or type your own width and height. With “Keep aspect ratio” ticked, changing the width updates the height automatically so the photo is never stretched.
- Pick a resize mode. Use Fit to keep the whole photo, Crop to fill to fill the frame exactly, or Stretch to force the exact size. In Crop to fill mode, use the crop position sliders to decide which part of the photo stays visible.
- Resize and download. Choose PNG, JPG or WebP, set the quality, then click Resize Image to see a preview and the new dimensions. Click Download Resized Image to save the finished file.
Worked Example
Take a holiday photo that is 2000 by 1500 pixels. First, resize it for Instagram: choose the Instagram preset, 1080 by 1080, with “Crop to fill” mode. The tool scales the photo so its shorter side fits the square, then crops the sides, giving you a 1080 by 1080 square that is exactly the size Instagram expects. If you move the horizontal crop slider to the left, the left side of the scene stays in the frame; move it right and the right side stays instead. Next, resize the same original for a LinkedIn post at 1200 by 627 pixels. Here the target is wider than the photo is tall, so “Crop to fill” scales the photo to 1200 pixels wide and trims a little from the top and bottom. In both cases the original file is untouched, and you can download each resized version separately. Resizing down from 2000 pixels to 1080 or 1200 keeps the picture looking sharp, because you are packing the same scene into fewer pixels.
Why Resize Images in Your Browser?
Most online image tools ask you to upload your photos to a remote server, where you have no control over how long they are kept or who can see them. That is a poor trade for a family photo, a passport picture or a client’s product shot. This tool does the resizing on your own device, inside your browser, so the image never travels over the internet at all. It is also faster for everyday jobs: there is no upload wait, no queue and no download link that expires. The only trade-off is that very large originals, such as a 40-megapixel camera file, may take a few seconds on an older phone, since your device is doing the work instead of a powerful server. For the photos most people resize, the result appears almost instantly.
Tips for a Clean Resized Photo
Always start from the largest original you have and resize down, never up: enlarging a small photo makes it soft, while shrinking a large one stays sharp. Keep the aspect ratio locked unless you genuinely want to change the shape of the picture, and use “Crop to fill” instead of stretching when the target shape is different from the original. Check the crop position before downloading, because a face near the edge of the frame can be cut off by an automatic centre crop. For photos, JPG at 85 to 90 percent quality is usually the best balance of size and sharpness; use PNG when you need exact colours or transparency, and WebP when you want the smallest file a modern browser can show.
Frequently Asked Questions
Is the image resizer really free?
Yes. Resizing and cropping images on this page is completely free, with no account, no sign-up and no watermark. You can resize as many images as you like.
Are my photos uploaded to a server?
No. Your image never leaves your browser. Resizing and cropping run entirely on your device, so your photos are never uploaded, stored or seen by anyone else.
What is the difference between fit and crop to fill?
Fit scales the whole photo into your chosen size without cutting anything off, so the result may have empty space on two sides if the shapes do not match. Crop to fill scales the photo until it covers the whole target size and trims the overflow, so the frame is completely filled but some edges are cut away.
Which size should I use for social media?
Use the presets on this page: 1080 by 1080 pixels for an Instagram square post, 1280 by 720 for a YouTube thumbnail, 1200 by 627 for LinkedIn, 1200 by 630 for Facebook and 1600 by 900 for X. Platforms change their recommendations from time to time, so check the platform if a post looks cropped.
Will resizing reduce the quality of my photo?
Making a photo smaller keeps it looking sharp, because the detail is packed into fewer pixels. Making a photo much larger than the original will look soft or blurry, because no new detail can be created. For the best result, start from the largest original you have and resize down, not up.
