How to resize images for social media
Choose your image
Upload or drop a photo, graphic, or logo. You can also paste an image from your clipboard or load an image URL that allows browser access.
Pick sizes and adjust the fit
Choose a platform preset. Crop to fill the frame, or fit the whole image with padding. Drag the image to adjust each crop, or use the sliders. Include the sizes you want in your ZIP.
Download your resized images
Save the preview as PNG or JPG, or download your selected sizes together in a ZIP. Everything is processed in your browser.
Common social media image sizes
Start with these presets, then check the platform preview before publishing. Profile photos and banners can be cropped differently on phones and desktop.

|---|---|
| Instagram Feed Portrait | 1080 × 1350 |
| Instagram Feed Square | 1080 × 1080 |
| Instagram Story | 1080 × 1920 |
| Facebook News Feed | 1200 × 1200 |
| LinkedIn Personal Banner | 1584 × 396 |

| YouTube Thumbnail | 1280 × 720 |

Crop for impact. Fit to keep every detail.
Crop to fill works well for photos with room around the subject. Move the crop to keep faces, products, and text visible. Fit entire image is useful for logos and finished graphics where cutting an edge would lose information.
Neither mode stretches your image. PNG keeps transparent areas; JPG fills them with your chosen background color.

Common questions
Frequently asked questions
Is this social media image resizer free?
Yes. Resize and download images without an account, watermark, or credits. Your image is processed locally in your browser, with no upload to Krumzi's servers.
Which social media platforms can I resize images for?
Choose image presets for Instagram, Facebook, LinkedIn, X (Twitter), YouTube, TikTok, Pinterest, Discord, Bluesky, and Product Hunt. Presets cover posts, stories, covers, banners, thumbnails, and profile images. Video-cover presets export a still image, not a video.
How do I resize an image without cropping it?
Choose Fit entire image. The tool keeps the original proportions and adds padding to reach the target size. Use a solid background color, or select PNG with a transparent background for clear padding.
Can I download several social media sizes at once?
Yes. Choose a preset and check Include this size in ZIP. Repeat for each size you need, then use Download selected ZIP. Each size remembers its own crop position. Fit mode, background, and file format apply to the entire set.
Will resizing reduce image quality?
Resizing changes the number of pixels. A larger output cannot recover detail missing from a small original, so the tool warns when a preset enlarges your image. PNG avoids lossy compression; JPG uses high-quality compression for smaller photo files. Platforms may compress your upload again.
Which image files can I use?
Use PNG, JPG, WebP, GIF, or another image format your browser can open. Local files can be up to 20 MB, with a maximum of 32 megapixels and 16,384 pixels per side. Animated images export as a still frame. Download as PNG or JPG.
Why does an image URL fail to load?
Some sites block other websites from reading their images. Download the image first, then upload the file here. A URL should point directly to an image, not a webpage.
