Resize Image for Instagram, YouTube & Social Media
Resize image for Instagram, YouTube, X, LinkedIn, Facebook and Pinterest by picking the platform instead of typing pixels. Choose Fill to crop to the exact frame or Fit to keep the whole photo and add bars in a colour you pick. A batch of photos comes back as one ZIP, and the photos never leave your device.

Formats
Batch-friendly: add many files and they are processed one after another — if one fails, the rest still finish.
How it runs
- WebAssembly codecs
- Images are encoded with Squoosh-grade codecs (MozJPEG, WebP, AVIF, OxiPNG, JPEG XL). Each codec loads only when you use it.
- GPU canvas
- Pixels are drawn and composited with the GPU-accelerated canvas.

Fill or Fit: what happens to a phone photo on each preset
Fill never adds bars but crops whatever does not match the platform’s shape; Fit never crops but adds bars. The table shows how much of an ordinary landscape phone photo (4:3) survives Fill, and how wide the bars are with Fit, for every preset in the list.
| Preset | Output size | Fill keeps | Fit adds |
|---|---|---|---|
| Instagram portrait post | 1080×1350 (4:5) | 60% | 540 px top and bottom in total |
| Instagram square post | 1080×1080 (1:1) | 75% | 270 px top and bottom in total |
| Instagram / Facebook Story | 1080×1920 (9:16) | 42% | 1110 px top and bottom in total |
| YouTube thumbnail | 1280×720 (16:9) | 75% | 320 px left and right in total |
| YouTube channel banner | 2560×1440 (16:9) | 75% | 640 px left and right in total |
| X / Twitter post | 1600×900 (16:9) | 75% | 400 px left and right in total |
| X / Twitter header | 1500×500 (3:1) | 44% | 833 px left and right in total |

What size should Instagram posts be?
For the feed, the image size for an Instagram post in this tool is 1080×1350 for portrait (4:5) and 1080×1080 for square (1:1). Portrait takes up the most height in the feed, so it is the default. Stories use 1080×1920 (9:16).
The profile grid shows a cropped preview of each post, so keep faces and text away from the edges even when the full post is the right size. A carousel looks tidiest when every slide uses the same preset.
What is the YouTube thumbnail size?
A YouTube thumbnail is 1280×720 pixels (16:9) and must be under 2 MB. This resizer saves JPG by default, which keeps a thumbnail of that size far below the limit. Channel banners are a separate preset at 2560×1440; YouTube shows a different slice of the banner on TVs, computers and phones, so keep logos and text in the middle.
Resize a photo for Instagram without cropping
Pick the preset, then choose Fit (pad). The whole photo is scaled to fit inside the frame and the empty space is filled with the Padding colour: white by default, or any colour you choose, such as black for a cinematic look or a shade that matches the photo. This is also how to post a wide landscape photo as a 4:5 post or a 9:16 story without losing either side.
To choose exactly what is cut instead, frame the photo first with the image cropper at 4:5 or 9:16, then resize it here.
Do you need to resize photos for Instagram?
Not strictly: every platform scales what you upload. But each one crops to its own shapes, and its automatic crop may not be the one you want. Preparing the exact size first means you decide what is kept, text stays where you put it, and a batch of product photos or a carousel comes out consistent. It also keeps uploads small, which helps on slow connections.
- Batch. One preset for a whole shoot, downloaded as one ZIP.
- JPG by default. Smaller than PNG for photos; switch Save as to PNG or WebP under Advanced settings when you need to.
- Private. Photos are resized by your browser; nothing is sent to a server, so unreleased product shots stay with you.
Tips & troubleshooting
Need a size that is not in the list, such as a WhatsApp profile picture or a custom banner? Use the image resizer with exact pixels.
For a round profile photo, make it square here and then use circle crop for a transparent PNG.
Several photos in one post? Build a 4:5 or 9:16 layout with the collage maker.
Resizing video for Reels or Shorts instead? The vertical video converter does the same job for clips.
Text on your image? Keep it inside the middle 80% of the frame so feed and grid previews do not cut it off.

Choose the Instagram preset and set Fit to Fit (pad). The whole photo is kept and bars in your padding colour fill the rest of the frame.

No. Your photos are processed by your own browser on your own device. There is no server that receives files, so nothing is uploaded, stored or shared. You can even switch to airplane mode once the page has loaded.
