HELP & ANSWERS

Frequently asked questions

What size does this YouTube preset create?+

The selected preset uses 1080 × 1920 px (9:16). You can enter custom pixel dimensions instead; platform recommendations can change, so check the latest publishing guidance.

Will the image be cropped to fit?+

Choose “Crop to fill” to trim edges, “Fit inside” to keep the full image with possible margins, or “Stretch” to change its proportions.

Can resizing make a small image sharper?+

No. Increasing pixel dimensions cannot recreate detail missing from the source image. Start with the largest clear original you have.
