Check the new size and save the file. The original is never changed.
What 20 KB means for a photo
20 KB is a strict limit, common for signatures and small ID photos on application forms. A phone photo has to be scaled down to a few hundred pixels across to fit.
Signatures fit easily because they're mostly blank paper. Crop close around the signature first so the space goes to the ink, not the paper.
If the form gives exact dimensions as well, use Resize image, or the Signature preset for a 300 × 80 signature.
Frequently asked questions
Can a passport-style photo fit in 20 KB?
Yes, at a small size such as a few hundred pixels across. Check the result still shows the face clearly.
How do I reduce a photo from MB to KB?
Drop the photo in and pick a target like 100 KB or 50 KB. Quality is lowered first; if that isn't enough, the photo is made smaller in pixels until it fits.
Can I compress an image without losing quality?
At the default setting the difference isn't visible on screen. Very small targets like 20 KB do lower the quality, so check the before and after view.
Which formats can I compress?
JPG, PNG and WebP are saved in the same format. AVIF, GIF and BMP files are read too and saved as JPG or PNG.
