Best practices for image resizing
Resize images to the largest size you actually need. Smaller dimensions reduce file size and help pages load faster, while keeping aspect ratio prevents faces, products, and screenshots from looking stretched.
Često postavljana pitanja
Can I keep the original aspect ratio?
Yes. Turn on keep aspect ratio, then changing width or height automatically updates the other side.
Does resizing upload my image?
No. Your image stays in your browser and resizing runs locally.
Which output format should I use?
Use PNG for transparency, JPG for photos, and WebP when you want a smaller web-friendly file.
