Frequently asked questions

Can I upscale?+

Yes, but enlarging cannot add real detail and may look soft.

Do you store uploads?+

No uploads occur — processing stays on your device.

How do I resize an image to exact pixel dimensions for a banner?+

Open ToolVera’s image resizer, enter the target width and height, and download. Lock aspect ratio when you only know one side so the image does not stretch.

Will resizing reduce file size as much as compressing?+

Smaller dimensions usually shrink files, but format and quality matter more for photos. Resize to the display size first, then compress if you still need a lower byte count.
