Fit Modes Explained

Crop & Fill — Scales your image to fill the target frame completely and crops any overflow from the edges. Best for most social media posts where the full frame must be used. Fit & Pad — Scales your image to fit entirely within the frame and fills the remaining space with your chosen background color. Best for logos, product images, or when no cropping is acceptable. Stretch — Forces your image to fill the exact dimensions, which may distort the aspect ratio. Use only when the original and target ratios are similar.

Frequently Asked Questions

What is the best image size for Instagram posts?

Instagram supports multiple sizes. For feed posts, 1080×1080px (1:1 square) is the classic choice, but 1080×1350px (4:5 portrait) uses more feed space and typically achieves better organic reach. For Stories and Reels, use 1080×1920px (9:16 vertical).

What size should a YouTube thumbnail be?

YouTube recommends 1280×720px (16:9) for thumbnails with a maximum file size of 2MB. Our tool outputs at this exact resolution. Keep important text and faces in the centre — edges may be cropped on mobile and TV screens.

Is this image resizer completely free?

Yes, 100% free with no login, no watermarks, and no daily limits. Your images are processed entirely in your browser using Canvas API — they are never uploaded to any server.

What image formats are supported?

You can upload JPG, PNG, WebP, GIF, BMP, and most other common image formats. The output format is determined by platform standards — JPG for most photos and PNG for images requiring transparency (logos, LinkedIn icons).

What is the difference between Crop & Fill and Fit & Pad?

Crop & Fill scales your image to fill the frame completely and crops any overflow — best for most social posts. Fit & Pad scales your image to fit entirely within the frame and fills remaining space with your chosen background colour — best for logos or images where no cropping is acceptable.
