Exactly 1280×720 pixels, the size YouTube asks a thumbnail to be
Processed in your browser. Nothing is uploaded. Updated on 25 Oct 2026.YouTube wants a thumbnail 1280 pixels wide and 720 tall, a plain sixteen by nine rectangle, and that preset is already selected here. A square screenshot dropped in loses the top and bottom to the centre crop, which is where most people put the title text, so look at the preview before downloading. Enlarging a small image to fill 1280 pixels adds pixels but no detail, and the tool says so when it happens.
Choose your image; the YouTube thumbnail preset is already selected at 1280×720 pixels, 16:9.
With Fill and crop, a square or tall image loses its top and bottom, so keep title text near the middle.
If the Output line says Enlarging adds pixels, not detail, the image is under 1280 wide and will look soft.
Press Resize, then Download the 1280×720 file and upload it as the video's thumbnail.
Resize Image changes the pixel size of JPG, PNG, WebP and iPhone HEIC photos and shows the result next to the original before you download it. Type a width or height, pick a percentage, or choose a preset, and the other side follows the photo's ratio unless you unlock it.
People use it to make a passport photo at 35×45 mm (413×531 pixels at 300 DPI) for Indian passport, visa and exam forms, to fit a picture to Instagram's square, portrait or story sizes, and to shrink a 12-megapixel phone photo down to something a website or email can handle. When a preset has a different shape from your photo, "Fill and crop" trims the centre so the output is exactly the size the form asks for.
Enlarging a small photo adds pixels but not detail, so keep enlargements under 200 percent when you can. Use Compress Image afterwards if a form also sets a file-size limit in KB, and Convert Image if you only need a different format.
The rest of the article, and all 7 questions about Resize Image, are on the Resize Image page.
Add the photo, open Presets and choose Passport photo (India). That sets 413 by 531 pixels, which is 35 by 45 mm at 300 DPI, the size most Indian passport, visa and exam portals ask for. Keep Fill and crop selected so the output is exactly that size, then download.
Fit inside keeps the whole photo and may leave one side shorter than the preset. Fill and crop makes the output exactly the preset size by trimming the centre. Stretch forces the size without cropping, which distorts the picture, so use it only for graphics.
File size in KB depends on both pixels and compression. Resize first to reduce the pixels, then use Compress Image with Target size mode to hit an exact KB limit.
Photo ka size badlein: type a width or height in pixels, drag the percentage, or open Presets and choose Passport photo (India), which sets 413 by 531 pixels. Fill and crop trims the centre so the output is exactly that size. Up to 20 images per batch, each 50 MB, capped at 10,000 pixels a side.
