Social Media Image Resizer

Frequently Asked Questions

How are images resized to fit the target dimensions?

Images are center-cropped to match the target aspect ratio, then scaled to the exact pixel dimensions. This means content at the edges may be trimmed if the aspect ratio of your original image differs from the preset. For best results, start with an image that is already roughly the right aspect ratio.

Why are social media platforms so specific about image sizes?

Each platform has design constraints: feed layouts, compression algorithms, and display contexts that work best with specific aspect ratios and minimum resolutions. Using the correct size avoids automatic cropping by the platform, prevents blurry upscaling, and ensures your image looks sharp across devices.

Does this tool upload my image to a server?

No. Resizing happens entirely in your browser using the Canvas API. Your image never leaves your device.

Can I download the resized image as JPEG instead of PNG?

Currently all downloads are in PNG format. PNG is lossless and works for all use cases, though the file size will be larger than JPEG. You can convert the PNG to JPEG using an image converter tool if a smaller file size is needed.
