Common target widths
1080 px is the safe default for social posts and marketplace catalogue images. 1920 px suits full-width website banners. 800 px is plenty for in-article images, and 400 px covers most thumbnails and grid tiles.
If you are preparing images for a marketplace listing, check the seller panel's stated minimum — several Indian marketplaces reject catalogue images below 1000 px on the shorter side, which is a more common upload failure than file size.
Frequently asked questions
- Does resizing keep the aspect ratio?
- Yes. You set the width and the height is calculated from the original proportions, so images are never stretched or squashed.
- Can I make an image larger?
- You can, but upscaling cannot invent detail that is not in the original file — the result will look soft. For enlargement beyond about 150% of the original width, start from a higher-resolution source instead.
- Can I resize many images at once?
- Yes, up to 25 files per batch. Every image is resized to the same target width and you can download the whole set as a single ZIP.
