A few useful details
Crop or fit: which should I choose?
Crop fills the frame by trimming the edges. Use the position sliders to keep the subject in view. Fit keeps the whole picture and fills any empty space with a background color.
Which size works for my post?
Square, portrait and vertical are useful starting points. Placement requirements vary between platforms, so check the preview in the app before publishing. Custom dimensions let you match a specific requirement.
Will making a photo bigger improve it?
No. Enlarging adds pixels, not detail. Start with a large original and avoid enlarging small images when you can.
Can I adjust brightness, contrast and saturation?
Yes. Open Photo adjustments and move the sliders to lighten or darken the photo, change its contrast or adjust color intensity. Zero keeps the original setting; saturation at -100 makes the photo black and white. Reset adjustments clears only these three settings. All changes are applied to the downloaded image, entirely in your browser.
