Frequently asked questions
How do I reduce an image's size in KB?
Lower the quality slider and compress. If it's still too large, resize the image to smaller dimensions first with our Image Resizer.

70–80% usually gives big savings with no visible difference for photos.
Can I compress PNG files?
Yes. PNGs are converted to WebP or JPG, which are much smaller.
