Frequently Asked Questions
Can I crop images for specific social media platforms like Instagram, YouTube, and Facebook?
Yes. The tool includes one-click presets for Instagram Posts (1:1), Stories (9:16), YouTube Thumbnails (16:9), Facebook Banners, Twitter/X Headers, and LinkedIn posts, as well as custom aspect ratio locking.
Does cropping or resizing reduce my image quality?
No. The tool uses high-fidelity bicubic resampling through WebAssembly to preserve crispness when resizing and performs lossless pixel selection when cropping. You can also adjust the output quality slider up to 100%.
What is the difference between 'Fit', 'Fill', and 'Exact' resize modes?
'Exact' scales the image precisely to your specified width and height. 'Fit' scales the image to fit entirely within the box while preserving aspect ratio. 'Fill' scales the image to completely fill the dimensions, cropping any excess edges.
Are my photos uploaded to any server while cropping or resizing?
No. All cropping, canvas rendering, and resizing algorithms run 100% locally on your computer or phone using in-browser WebAssembly. Your photos never leave your device.
Can I convert the image format while resizing or cropping?
Yes! You can choose to keep the original image format or export directly to WebP, PNG, or JPG upon completing your crop or resize.
