Frequently asked questions
How do I reduce a photo to under 20KB?
Add your photo above. We keep the best JPG quality that lands under 20KB, and only shrink the picture if quality alone isn't enough. Add an exact width and height if your form asks for one.
Which pixel size should I use?
If the form gives a size in pixels, enter it as width and height — we'll crop the photo to fit, centred. If it only gives a file size, leave them empty.
What format is the result?
A JPG file, which almost every upload form accepts. PNG and WebP photos are converted with a white background.
Are my photos uploaded anywhere?
Nothing is uploaded. Your files are processed right here in your browser and never leave your device, so we never see them.
