Before you post
Ad image resizer.
Keep the whole message.
Resize one product ad to your chosen pixel width and height, or compare preset ratios. Move the crop, or fit the complete image on a plain background. Download the PNG you reviewed and a text record of the settings.
PNG, JPEG or WebP · up to 15 MB / 40 MP. The image is processed in this page and is not sent to Panelly. PNG exports use a cream background, including transparent source areas.
0% keeps the left or top edge; 100% keeps the right or bottom edge. A slider has no visible effect when that axis needs no crop.
Keep the story in frame.
Choose an image to compare the complete ad with a different canvas. Nothing is generated.
A geometry check, then your judgement
Four panels need four checks.
Read the opening, product detail, context and final action after changing the ratio. This tool crops or adds a plain background; it does not rearrange panels, restore hidden text or use AI to extend an image. A fit can make text smaller.
Ratios are generic working canvases, not platform upload specifications or safe zones. Check the actual placement preview in your publishing account. PNG output can change dimensions, encoding, metadata and pixels through scaling; keep the original file.
