Steps to resize image for youtube thumbnail
- Add the picture. It stays in this tab while you resize image for youtube thumbnail.
- Confirm the frame is 1280 by 720 pixels. Cover is selected, lock aspect is on, and do not enlarge is off.
- Run the resize. Cover center-crops to that exact frame, and the pixels are resampled with Lanczos.
- Download the picture. If the subject sits in a corner, the crop may have cut it, so look before you submit the file.
How this target is applied
Cover center-crops to the exact 1280 by 720 pixel frame. The crop is centred, so the subject should sit in the middle. A square photo in this wide frame loses the top and bottom. A photo that is already this shape keeps more of the original.
Do not enlarge is turned off, so a smaller original can grow to 1280 by 720. The pixels are resampled with Lanczos. A shrink from a large photo stays clearer than a blow up. DPI is 0. The density note is not what makes this frame.
Why 1280 by 720 pixels
A YouTube thumbnail is a 1280 by 720 pixel frame, 16:9, the same shape as the player. This page opens there so the still fills the slot. Cover center-crops. Important text should sit in the centre, because the sides of a square drawing will be cut and the player may also cover a corner with a duration badge later. This tool only sets the pixels.
The page opens with those numbers, fit on cover, lock aspect on, and do not enlarge off.
What to expect from the crop
A large photo is center-cropped and resampled with Lanczos down to 1280 by 720. Edges outside the frame are gone. A small photo grows to the same frame because do not enlarge is off, and the growth looks softer.
Look at the download before you post it. Titles near an edge are the first thing cover removes.

Your file never leaves your device
Your picture is processed only in this browser and is never uploaded. The work runs in a Web Worker in this tab, using WebAssembly for the heavy parts, and the result comes back as a local blob. This site does not upload the file, store it, or log its name.
To verify: load the page, turn on airplane mode, and drop the file again. It still finishes. Or open DevTools, choose Network, and watch the run: there is no upload. The architecture is described on How it works.
Frequently asked questions
Will cover cut the picture at 1280 by 720?
Yes, when the original is not already 1280 by 720. Cover center-crops to the exact frame, keeping the centre and trimming the edges. Put the subject in the middle and check the download. The pixels are resampled with Lanczos. A matching wide photo loses less than a square one.
Can a smaller original grow?
Yes. Do not enlarge is turned off, so a smaller original can grow to 1280 by 720. The pixels are resampled with Lanczos. Growth looks softer than a shrink from a large photo, because new pixels are invented. Start from a larger file when the image will be viewed full width.
Is 1280 by 720 the thumbnail frame?
Yes. This page opens at 1280 by 720 for a YouTube thumbnail. Cover center-crops to that 16:9 frame. A square design loses the top and bottom, so keep titles near the centre. Do not enlarge is off, and the pixels are resampled with Lanczos.
Does DPI add pixels on this frame?
No. DPI is 0 on this preset, and a density note would not add pixels even if it were set. The frame is the pixel width and height only. This is a screen image. A print preset is the one that writes 300 DPI, and even that preset does not invent extra pixels.
What if I needed another size?
Type the other width and height before you run. This page opens on 1280 by 720 so that slot is ready. Lock aspect is on and fit is cover, which forces the exact frame rather than a picture floating inside it. Cover will crop again if the new shape does not match the photo.
