How to resize an image for social media
Pick the destination first, then decide whether preserving the full image or filling the frame matters more.
01
Choose a preset
Select the platform and asset type. The exact pixel dimensions and aspect ratio update immediately.
02
Add one image or a batch
Drop browser-supported images into the tool. Processing starts locally on your device.
03
Review and download
Choose Crop to fill or Fit, select PNG or JPG, then download one file or a ZIP.
Crop to fill or Fit (pad)?
Crop to fill
Fills every pixel at the selected ratio. The tool uses a centered crop, so edge content may be removed.
Fit (pad)
Keeps the complete image inside the target canvas. Empty space can appear when ratios differ.
What the preset controls
- Pixel dimensions: every result uses the selected width and height.
- Aspect ratio: this determines the crop or padding needed to reach the target frame.
- Output format: PNG retains transparency; JPG generally creates smaller photographic files.
Images stay in your browser
Resize and batch export run on your device. The tool does not need to upload the selected image files to an image-processing server.
Image size and resizing FAQ
Does resizing crop my image?
Crop to fill uses a centered crop so the canvas is filled at the exact preset dimensions. Choose Fit (pad) when you need to preserve the full image without cropping.
Can I resize several images at once?
Yes. Add multiple browser-supported images, apply one preset and download individual files or one ZIP archive.
Should I choose PNG or JPG?
PNG preserves transparency and is useful for graphics. JPG is usually smaller for photos, but transparent areas are placed on white because JPEG has no alpha channel.
Are these dimensions official for every platform?
The source section identifies dimensions checked against stable first-party documentation. Other entries are practical presets and are not presented as mandatory platform rules.
Official sources and verification
These primary sources cover the platforms that publish stable image specifications. Other entries are maintained as practical presets and are deliberately not described as official requirements.
