Turn one photo into every Bluesky size in seconds. Pick what must stay in the crop, then download one file or all of them.
Your photo is resized inside your browser. It is never uploaded to our servers.
Each size comes from the network's own help or spec pages, linked under its table, with the date we last checked it.
We found no size Bluesky recommends. A post holds up to 4 images, and each must stay under the file limit shown here, so the download is compressed until it fits.

No. The photo is read and resized by your own browser, and the files you download are made on your device. Only the list of sizes comes from our server.
From each network's own help or specification pages, linked under every table with the date we last checked them. Where a network publishes only limits (such as a width range), the sizes are marked as fitting those limits rather than recommended by the network.
Fill & crop covers the whole size with your photo and trims what does not fit, keeping the point you clicked in view. Fit whole photo keeps every part of the photo and fills the empty space with a border colour you choose.
It is free, with no account, no limit on photos and no watermark.
