How to compress an image
Three steps, about ten seconds.
- 01
Add your image
Drop a JPG, PNG or WebP in the box above, or tap to choose one from your phone or computer.
- 02
Pick a target
Keep the best-quality default, or choose a size like "Under 100 KB" if a form has a limit.
- 03
Download
Check the new size and save the file. The original is never changed.
How a photo gets under 50 KB
For JPGs, the highest quality that still fits is found first, down to a floor of 35%. Only if that's not enough is the photo made smaller in pixels, a step at a time.
PNGs stay PNG: they're reduced to fewer colours first, then made smaller. For photos saved as PNG, switching the format to JPG keeps much more detail at 50 KB.
If the form also gives pixel dimensions, use Resize image, which sets the size and the 50 KB limit together.
Frequently asked questions
Why did my photo get smaller in pixels?
At 50 KB, lowering quality alone wasn't enough, so the image was scaled down until it fitted.
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.
