How to use this social image resizer
This free social image resizer works in three short steps. First, choose an image from your device, or drag and drop it onto the tool area. Second, choose a preset for the platform you need, or choose Custom and enter your own width and height. Third, choose Crop to fill or Fit inside, check the preview and the output dimensions, then use the Download button to save the resized image as PNG or JPG. Your image never leaves your browser: all resizing happens locally with canvas, so there is no upload, no storage, and no account.
Preset sizes
The presets cover the main platforms. YouTube: thumbnail 1280 by 720, channel art 2560 by 1440. Instagram: post 1080 by 1080, story and reel 1080 by 1920. Facebook: post 1200 by 630, cover 851 by 315. X: post 1600 by 900, header 1500 by 500. TikTok: video 1080 by 1920. LinkedIn: post 1200 by 627, cover 1584 by 396. If you need a different size, choose Custom and enter the width and height you need, and the tool will resize to exactly that size.
Crop to fill vs fit inside
Crop to fill, also called cover, fills the whole target size and crops the edges that do not fit. It is best when you need an exact size with no empty borders, such as a YouTube thumbnail or an Instagram post. Fit inside, also called contain, shows the whole image with no cropping, and adds a white background around it to fill the remaining space. It is best when you must not cut anything out, such as a logo or a photo with important detail near the edges. Try both modes on your image and choose the one that looks best for that platform.
Privacy and upscaling
Privacy is simple with this social image resizer: your image never leaves your browser. All resizing happens locally on your device with canvas, so there is no upload, no storage, and no account. No one else sees your image, and nothing is sent to a server. Upscaling is a different issue: if your image is smaller than the size you pick, the tool will still resize it, but the result can look blurry. Upscaling a small image can look blurry, so start from the largest image you have whenever you can, especially for large presets such as YouTube channel art or a LinkedIn cover.
Which format should I download?
Choose PNG for graphics and text, because PNG keeps sharp edges and text clear, and it supports transparency. Choose JPG for photos, because JPG files are smaller and photos do not need the sharp edges that PNG preserves. This tool offers both format buttons in the download format list, so you can switch before you download. If you are not sure, start with PNG for a logo, a graphic, or an image with text, and use JPG for a photograph that you want to keep small for sharing.
Frequently asked questions
Does my image leave my browser?
No, everything happens locally on your device. Your image never leaves your browser, and nothing is uploaded or stored.
Which size should I use for an Instagram post?
Use 1080 by 1080 for an Instagram post, which is the square preset in this tool.
What if my image is smaller than the size I pick?
The tool will still resize it, but upscaling a small image can look blurry. Start from the largest image you have for the best result.
Should I download PNG or JPG?
Use PNG for graphics and text, and JPG for photos. PNG keeps sharp edges, while JPG keeps photo files smaller.
Can I resize more than one image at a time?
One at a time in this version. Choose one image, resize it, download it, then choose the next image.
Tips for better results
Start with the largest, sharpest original you have, and avoid resizing the same image many times, because each resize can soften detail. Check the preview before you download, especially in Crop to fill mode, where the edges are cut off. If an important subject is near the edge, switch to Fit inside, or choose a preset that matches your image's shape more closely. For social posts, keep text large and simple, because small text can become hard to read after resizing and compression on the platform. Finally, keep a copy of your original image, so you can resize it again for a different platform without losing quality.
