When to export an OG image
Use cover when the photo should fill the card (typical for a blog or product). Edges will be cropped. Use contain when you must keep the whole graphic — logos and screenshots — and accept white bars. You can change the quality slider the same way as Compress.
This is the same 1200×630 job as “OG image size” on social lists. It lives here so you can also pick JPG, PNG, or WebP. For a favicon pack, use Favicon. For Instagram or TikTok, use those size pages instead.
After download, compress if a CMS still has a cap. If you need to shift the crop or add a title, use Photasium then export 1200×630 here.

Tips
- Most link previews look sharper if faces sit near the centre before you cover-crop.
- PNG is larger. JPG at quality around 0.86 is enough for a share card.
- You can also start from the common sizes row on Resize.

FAQ
- Why 1200×630?
- It is the size most Open Graph and many iMessage previews expect. Other ratios get letterboxed or cropped by the app.
- Cover or contain?
- Cover fills the card and crops. Contain keeps the whole picture and may add white bars.
- Do you upload the photo?
- No. The export happens in this browser.
