To crop an image to a 16:9 aspect ratio for free, open the SammaPix Crop tool, select the 16:9 preset, drag the crop box over the part of the image you want to keep, and download.

Everything runs 100% in your browser — no upload, no signup, no watermark — and cropping removes only the pixels outside the frame, so there is no quality loss.
Open the SammaPix Crop tool and drop your image in. Supports JPEG, PNG, and WebP.
Choose the 16:9 ratio. The crop box locks to 16:9 — drag and resize it over the area you want to keep.

16:9 is an aspect ratio — these are the pixel sizes people most often export after cropping.
| Use | Pixels (W × H) |
|---|---|
| YouTube thumbnail | 1280 × 720 |
| Full HD video / slide | 1920 × 1080 |
| 4K frame | 3840 × 2160 |
16:9 is the native frame for YouTube, so crop your thumbnail to 16:9 before uploading to avoid black bars or auto-cropping.
Keep the key subject inside the central safe zone — YouTube overlays the duration badge in the bottom-right corner of the thumbnail.
For a 1080p slide or video frame, crop to 16:9 then export at exactly 1920×1080 px for pixel-perfect output.
If your source is a tall phone photo, you will lose top and bottom — reframe so the horizon and subject sit in the wider middle band.
Ready to crop?
Use the Crop tool to crop your image to 16:9, or browse all aspect ratios.
16:9 is an aspect ratio, not a fixed size. Common 16:9 resolutions are 1280×720 (HD), 1920×1080 (Full HD), and 3840×2160 (4K). Any width and height that divide to 1.778 is 16:9 — for example 1600×900.
Open the SammaPix crop tool, choose the 16:9 ratio, drag the crop box over the part of the image you want to keep, and export. For a thumbnail, target 1280×720 px — YouTube's recommended thumbnail size.
No. Cropping only removes pixels outside the frame — the pixels you keep are untouched, so there is no quality loss. Quality only drops if you then upscale the cropped result beyond its original resolution.
Use 16:9 for modern video, YouTube, and widescreen displays. Use 4:3 for older screens, classic photography, and some presentation templates. 16:9 is wider and more cinematic; 4:3 is taller and shows more vertical content.
Crop to 9:16
The full-screen vertical standard — perfect for Instagram Reels and Stories, TikTok, YouTube Shorts, and Snapchat (typically 1080×1920 px).
Crop to 1:1
The classic square — perfect for Instagram feed posts, profile pictures and avatars, album covers, and product thumbnails that display as a square.
Crop to 4:3
The classic standard — perfect for traditional photography, iPad and tablet screens, older monitors and TVs, and many presentation templates.
Crop to 21:9
The cinematic ultrawide format — perfect for film-style photos, ultrawide monitor wallpapers (3440×1440 px), and wide website hero banners.
