What to know before you start
Resize to match the use case
A photo for email or a form rarely needs more than 1200-1600px width. Reducing dimensions alongside quality gives the biggest size savings.
Choose a modern format
Converting to WebP can reduce size by 25-35% compared to JPEG at the same quality, which helps when the target size is strict.

How much can I reduce a photo's file size?
Most phone photos can be reduced 60-90% by combining quality and dimension adjustments while still looking great on screens.
Will reducing file size make the photo blurry?
Moderate quality reduction (70-80%) is usually invisible. Blur only appears with very aggressive settings or heavy upscaling.
