The passport-photograph ceiling. Almost every Indian application form that wants a face photo states 20–50 KB, and 50 KB is the common upper bound. This page opens the image compressor with the ceiling already set to 50 KB, so the only thing left to do is drop the picture in. The quality is searched rather than guessed at, and the resolution comes down only once quality on its own cannot reach the number. A head-and-shoulders photograph at the usual 200×230 or so is fine here and stays recognisable, which is the only thing the ceiling is really protecting.
This runs in your browser. The file is not uploaded, there is no account to create, and nothing is added to the document you download.
Also searched for: compress image to 50kb, reduce photo size to 50kb, compress jpg to 50kb, make image less than 50 KB. It is the same tool whichever way you found it.
Yes — 50 KB is what the forms themselves ask for, so a photo compressed to it is the photo they expect. What they also check is the pixel dimensions, and those are a separate requirement: crop the picture to the size the form states first, then compress, rather than the other way round.
Then you are told so rather than handed a file that misses the mark quietly. The smallest version the ladder reached is offered instead, with its real size next to it, and you are never given something larger than what you put in — if nothing beats your original, you get your original back.
It is handed straight back, untouched. The ceiling is the whole requirement and it is already met, so re-encoding it would only spend quality to make a file that was already acceptable slightly smaller.
Only the file, until it has to change the picture. JPEG quality comes down first, which throws away detail the eye is worst at noticing; the pixel dimensions only shrink once quality alone cannot reach the number, and the notes say when that happened and what the image ended up as.
No. The file is opened, changed and written by this browser tab — it is never sent to a server, so there is no queue to wait in and nothing to delete afterwards. Once the page has loaded you can turn the network off and the tool still works.
