Crop, resize or compress: preparing images for social media

An image can have the wrong shape, too many pixels or an oversized file. These are different problems. Cropping changes which part of a scene remains visible; resizing changes pixel dimensions; compression aims to reduce bytes. Conversion changes the file format. You do not always need all four operations.

For a coffee shop promotion, keep the original photograph and prepare a copy for each destination. Decide what must remain visible before changing the file: the cup, the drink name and the price. If cropping removes one of those details, a smaller file still communicates poorly.

Fitting the whole photograph inside the square while preserving its proportions produces a 1080 × 675 image. That leaves 405 pixels of vertical space: about 202.5 above and below when centered. Your chosen background fills that space. The entire photograph stays visible.

Filling the square scales the photograph to 1728 × 1080. There are 648 extra horizontal pixels: a centered crop removes 324 from each side. Move the framing toward the subject when necessary. These numbers describe this example, rather than a universal social network requirement.

Do not stretch 1600 × 1000 straight into 1080 × 1080 by scaling each axis differently: faces and cups will change shape. In the Antrapost resizer, compare fit and fill, reposition the crop and inspect the preview before downloading.

JPEG uses lossy compression and often suits photographs. PNG preserves the image without that loss and supports transparency, making it an option for a logo with a transparent background. WebP also supports transparency and either lossy or lossless compression. Choose based on the visible result and the formats your destination accepts.

Converting a blurry photo to PNG cannot restore detail. Converting a logo with a white background to PNG does not remove that background either. JPEG does not preserve transparency, so inspect the background color before converting a transparent asset. Keep the original to try alternatives without accumulating losses.

Start with the correct framing and sufficient dimensions for the intended use, then compare file sizes. Inspect text edges, gradients and product details when compressing. Raise the quality or change the format if you see blocks or halos.

Try exporting two versions at different quality settings. Open both at their intended viewing size and check whether you can distinguish them. Choose the smaller version that preserves what matters. If the new file is larger, keep the previous one: conversion and quality changes do not guarantee a smaller file.

Check the downloaded image on your phone. Can you read the price without zooming? Is the subject intact? Has the background changed? Review every variant rather than only the first. For a series, keep margins and text sizes consistent.

Antrapost image tools process the file in your browser. Downloading an image does not publish it to social media. Bring the reviewed version into the editor, select your accounts and check the destinations before confirming. Store the original separately for future adaptations.
