Frequently asked questions
How do I reduce a photo to 100 KB?
Select your photo above. The size target is already set, so the tool immediately produces a JPG under 100 KB and shows the exact size before you download.
Will the photo lose quality?
The tool keeps the highest JPG quality that still fits under 100 KB. Only if that isn't enough does it reduce the pixel dimensions, and it tells you when it does.
Is my photo uploaded anywhere?
No. The resizing happens inside your browser and the image never leaves your device.
