Instagram Image Resizer
Resize any photo to 1080 × 1080 pixels for an Instagram post — cropped to fill, so nothing is squashed. Free, in your browser.
Runs in your browser — nothing is uploadedWhat size is an Instagram post?
1080 × 1080 pixels (1:1). Drop your photo here and it is resized to exactly that size: "Crop to fill" trims what doesn't fit so nothing is stretched, and you can keep the top, centre or bottom. The size list also has the 1080 × 1350 portrait post (4:5, which takes more space in the feed), the 1080 × 566 landscape post and the 1080 × 1920 story.
Image Resizer changes the pixel dimensions of an image — for example to fit a website banner, a social media post, a passport photo requirement or an upload form. Enter an exact width and height in pixels or scale by percentage.
The aspect ratio lock keeps proportions intact so images do not look stretched. Resizing happens in your browser.
When to use it
- Meeting exact size requirements on application and exam forms.
- Preparing images for social media posts and profile pictures.
- Making photos smaller before emailing or uploading.
- Creating thumbnails for websites and stores.
Tips for better results
- Keep the aspect ratio locked unless a form requires exact dimensions.
- Shrinking keeps images sharp; enlarging small images makes them blurry.
- Use Image Cropper first if you need a different shape, then resize.
How to use the Image Resizer
- Drop your image.
- Enter the target width and height in pixels or percent.
- Lock or unlock the aspect ratio, then click Resize and download.
Frequently asked questions
Will my photo be stretched?
No. "Crop to fill" keeps the proportions and trims the edges; "Fit inside" shows the whole photo with a border in the colour you choose. Only "Stretch" changes the proportions.
Any tips for this size?
Portrait 4:5 posts show bigger in the feed than square ones.
Is my photo uploaded?
No. It is resized by your browser on your device and never leaves it.
What does the aspect ratio lock do?
When locked, changing the width automatically updates the height (and vice versa) to keep the original proportions.
Is the file uploaded?
No. Resizing happens in your browser using the Canvas API.
Is there a file size limit?
The limit is shown in the drop area (typically 30–50 MB per image). It exists only to keep your browser responsive — the file is processed on your device and never uploaded. Very large photos are faster to process on a computer than on an older phone.
Will resizing reduce the file size?
Yes. Fewer pixels means a smaller file. For the smallest files, resize first and then compress.
