Image Resizer & Cropper
Resize any image to exact pixel dimensions with a draggable crop frame. Everything runs in your browser — no upload, no account, no watermark.
PNG, JPG, or WebP
Resize to exact dimensions, not approximations
Type the width and height you need and position the crop frame over the part of the image that matters. The tool exports exactly those pixels — essential for platform specs like YouTube's 1280×720 thumbnail or square profile pictures.
Crop composition matters more than scaling
Most 'resize' jobs are really crop jobs: the source is the wrong aspect ratio. The draggable frame lets you choose what survives the crop — keep faces large and near the center, since thumbnails are mostly seen at small sizes.
Frequently asked questions
What size should a YouTube thumbnail be?
1280×720 pixels (16:9). YouTube requires at least 640 px wide and a file of 2 MB or less for standard thumbnails.
Does resizing reduce quality?
Scaling down keeps images sharp. Scaling up cannot add detail — start from the largest source you have.
Is my image uploaded?
No. Cropping and scaling run on a canvas in your browser; the file never leaves your device.
