Guides

Practical guidance for choosing formats, balancing quality and preparing images safely.

JPG or WebP: choose for the destination

A useful format depends on where your image will be viewed, not just on the smallest number of bytes.

Find a useful compression quality

Reduce weight carefully while checking the parts of an image that matter to your audience.

Fit or crop without stretching

Two images can have the same output dimensions and very different composition.

What metadata cleaning can and cannot do

A fresh export removes source metadata without making the visible image anonymous.

Keep transparency when converting images

Choose the output format deliberately so logos and graphics keep the intended background.

Image limits, storage and result recovery

Browser processing keeps files local, but it still needs memory and device storage.
