How to Crop Screenshots for Social Media
SmarterSources' Screenshot Cropper makes it easy to crop any screenshot to the exact dimensions required by social media platforms. Everything runs in your browser — nothing is uploaded to any server, so your screenshots stay completely private.
Step 1: Upload Your Screenshot
Drag and drop a screenshot onto the tool, or click to browse your files. The tool supports PNG, JPG, WebP, GIF, and BMP formats — covering any screenshot format your device might use.
Step 2: Choose a Preset or Free Crop
Select one of the built-in social media presets to lock the crop area to the exact aspect ratio for that platform. Available presets include Instagram Post (1080×1080), Instagram Story and TikTok (1080×1920), YouTube Thumbnail (1280×720), Twitter/X Post (1200×675), Facebook Post (1200×630), and LinkedIn Post (1200×627). Choose "Free Crop" if you need a custom size.
Step 3: Adjust and Download
Drag the crop selection to position it over the part of your screenshot you want to keep. Resize it by dragging the corner or edge handles. The rule-of-thirds grid overlay helps you compose your crop. When you are satisfied, click "Crop & Download" to save the result.
Automatic Scaling to Platform Dimensions
When you use a social media preset, the cropped area is automatically scaled to the platform's recommended pixel dimensions. For example, if you select the YouTube Thumbnail preset and crop a region of your screenshot, the output file will be exactly 1280×720 pixels — ready to upload directly.
Privacy First
Your screenshots are processed entirely within your browser using the HTML5 Canvas API. No files are uploaded to any server. Your data never leaves your device.
Frequently Asked Questions
What social media presets are available?
The tool includes presets for Instagram Post (1080×1080), Instagram Story (1080×1920), TikTok (1080×1920), YouTube Thumbnail (1280×720), Twitter/X Post (1200×675), Facebook Post (1200×630), and LinkedIn Post (1200×627). You can also use Free Crop for any custom dimensions.
Does the tool upscale or downscale my screenshot?
When you use a social media preset, the cropped area is scaled to match the preset's exact pixel dimensions. If your selected area is smaller than the preset, it will be upscaled. If larger, it will be downscaled. For Free Crop, the output matches the exact pixels you selected — no scaling is applied.
What image formats are supported?
The Screenshot Cropper supports all common image formats: PNG, JPG/JPEG, WebP, GIF, and BMP. The output is saved in the same format as your original screenshot to preserve quality and transparency.
Is there a file size limit?
There is no artificial limit. Since all processing happens in your browser, the only constraint is your device's available memory. Most devices handle screenshots up to 50-100MB without any issues.
Can I crop the same screenshot multiple times with different presets?
Yes. After downloading a cropped version, simply select a different preset and adjust the crop area. You can download as many versions as you need without re-uploading the screenshot.
Will cropping reduce image quality?
The pixels within your selected crop area are preserved at their original quality. When a preset requires scaling, high-quality bicubic interpolation is used for the best possible result. Free Crop outputs the exact pixels with no quality loss at all.
