Choose the right dimensions
A photo intended for a screen rarely needs the full dimensions produced by a modern camera.
Resize, then compress
Resize close to the intended display size, then use moderate compression and compare the result with the original.
Common mistakes
Avoid enlarging a small photo, repeated re-encoding, and deleting the original before review.
Frequently asked questions
Should I resize or compress first?
Resize first when the dimensions are much larger than you need, then compress the resized copy.
Can file size drop without visible quality loss?
Often yes, especially when oversized dimensions or unnecessary metadata are removed.
Which format is best for photos?
JPG and WebP are commonly efficient for photos, while PNG is better suited to graphics and transparency.
