Frequently asked questions
Which size do I need for the web?
1200–1600 px width is enough for most websites and social media. Smaller images load faster.
Can I enlarge an image?
Yes, but enlarging cannot add detail – the image becomes softer. Shrinking keeps it sharp.
How do I reduce the file size?
Reduce the pixel size and choose JPG or WebP with 70–85 % quality. For even smaller files use our image compressor.
