Frequently asked questions
What image size is best for YouTube thumbnails?+
A long edge of about 1280px keeps the image sharp on screen while staying light. This tool targets that width and a file under 300 KB so uploads are fast and never rejected.
Does it crop my photo?+
No — it scales the whole image down proportionally to 1280px and compresses it. Use a dedicated crop/resize tool first if you need an exact aspect ratio.
Is my photo private?+
Completely. The resize and compression run on your device; the image is never sent to a server.
Can I do several at once?+
Yes. Drop multiple files and download them together as a ZIP.
