About this tool
The og:image that link previews show on Facebook, LinkedIn, Slack, Discord, and iMessage is expected at 1200 × 630 (1.91:1); X prefers 2:1 for summary cards. Drop a screenshot or design and get a JPG at the exact size so nothing is cropped unpredictably by each platform.
Keep the file under about 300 KB so previews load instantly: run it through Compress Image if needed.

Questions
Fill or fit?
Fill crops the edges so the image covers the whole frame, which is right for photos. Fit keeps the whole image and pads the rest, which is right for logos and text.
Can I batch resize?
Yes. Drop several images and each is resized to the selected preset; download them one by one or as a ZIP.
Does it keep transparency?
PNG output keeps transparent areas; JPG output fills them with white. Pick the format that the platform accepts.
Is it free, are files uploaded, which browsers work: the general questions are answered once for the whole site.
