Check the new size and save the file. The original is never changed.
Compressing to 100 KB
Most phone photos fit in 100 KB once they're scaled to a normal screen size, and still look clear. The tool keeps the highest quality that fits and only shrinks the picture if it has to.
Screenshots and graphics with large flat areas often get under 100 KB without being resized at all.
Need it smaller still? Try the 50 KB or 20 KB preset, or set your own target.
Frequently asked questions
Will a 100 KB photo look blurry?
Usually not at normal screen size. Zoomed in, very fine detail is softer than the original.
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.
