Common Questions
How do I make an image file smaller?
Upload the image, lower the quality slider, optionally set a max width, then compress and compare the new file size.
Which format is best for smaller image files?
WEBP and JPG usually create smaller files. PNG is better when transparency or crisp graphics matter, but it may not shrink as much.
