Resize a photo for a social media format
Choose a JPG, PNG, WebP or HEIC image, enter the width and height you need, then download the resized file.
Your image never leaves your device. Resizing and encoding happen in this browser tab with the Canvas API. There is no upload, account, or server copy.

“Crop to fill” trims the edges evenly around the centre to reach the exact shape. “Fit entire image” keeps everything visible and adds white or transparent space.
Higher quality keeps more detail and usually creates a larger file.

Sizes and aspect ratios
Choose a size that matches the frame
Social platforms display the same image differently across feeds, profiles, and stories. Matching the main frame reduces unexpected cropping, but it cannot guarantee the same crop everywhere. These presets are practical starting points used by many publishing workflows, not permanent platform rules.
| Placement | Common pixels | Shape |
|---|---|---|
| Instagram square post | 1080 × 1080 | 1:1 |
| Instagram portrait post | 1080 × 1350 | 4:5 |
| Instagram story / Reel | 1080 × 1920 | 9:16 |
| Facebook feed image | 1200 × 630 | 1.91:1 |
| YouTube thumbnail | 1280 × 720 | 16:9 |
| X post image | 1600 × 900 | 16:9 |
| LinkedIn feed image | 1200 × 627 | 1.91:1 |
| Pinterest pin | 1000 × 1500 | 2:3 |
Crop or fit: choose deliberately
“Crop to fill” gives a centred, full-bleed image with no empty bars, but it may remove the top and bottom of a portrait or the sides of a landscape photo. “Fit entire image” preserves every part of the photo and adds space around it. For a portrait being placed into a wide banner, fit mode is usually safer. For a thumbnail where the subject is centred with room around it, crop mode often looks better.
The preview updates before you process the file, so check the subject’s face, text, and any logo near the edges. If you need a different crop position rather than a centre crop, the exam resizer includes draggable crop positioning, or you can crop in a photo editor first and then resize here.
Keep the file size sensible
Large pixel dimensions are not always necessary. A 1080-pixel image is usually sufficient for a feed post and loads faster than a 4000-pixel camera original. If a platform or upload form has a KB limit, resize first and then use the image compressor. For photographs, JPG is a reliable default; use PNG when sharp text, flat colours, or transparency matter.
Need a custom size instead? Open the image resizer. For the underlying concepts, read the guide to dimensions and aspect ratios.
Questions
Social media image resizing FAQ
How do I resize an image for social media without cropping the subject?
Choose a preset, then switch “Sizing mode” to “Fit entire image”. The whole photo remains visible and the tool adds space around it. If you need the frame completely filled, use “Crop to fill” and check the preview before downloading.
What size should an Instagram post be?
A common square target is 1080 × 1080 px, and a common portrait target is 1080 × 1350 px. These are useful starting points, not permanent platform rules. Instagram and other platforms can change recommended dimensions and cropping behaviour, so check the current guidance for important campaigns.
Why does a tall image get cut off in a square post?
A square frame and a tall photo have different aspect ratios. Filling the square means trimming the top, bottom, or sides. Use fit mode if the full image must remain visible, or use a portrait preset that better matches the photo.
Are the social media presets official platform specifications?
No. They are common pixel sizes used by many publishing workflows. Platforms can change crops, safe areas, and recommendations at any time. Use these presets as a practical starting point and verify critical dimensions in the platform’s current help documentation.
Can I resize a photo for social media privately?
Yes. The image is loaded, resized, and encoded in your browser. It is not uploaded to PhotoResize. Remember that uploading the finished image to a social network is a separate action governed by that network’s privacy policy.
Which format is best for social media?
JPG is widely accepted for photographs and keeps files smaller. PNG suits graphics with text, sharp edges, or transparency. WebP can be efficient, but check that the destination platform accepts it if you are uploading the file directly.
