How do I reduce a photo to under 100KB?

Drop your file into the tool above. The compressor will automatically analyze the image and reduce its quality and dimensions until it fits comfortably under the 100KB limit.

Why is my image still larger than 100KB?

If your image contains extreme amounts of detail (like a dense forest or a crowd of people), compressing it to 100KB might require scaling down the physical width and height significantly.

Will compressing to 100KB make my photo blurry?

Generally, no. A 100KB limit provides plenty of data for a standard web image. Unless your original photo was a massive RAW file, the visual difference should be barely noticeable.

Which format is best for a 100KB image?

JPG is excellent for 100KB photographs. For images with sharp lines, text, or transparency, use WebP to avoid the "halo" artifacts that JPG introduces.
