Frequently Asked Questions

Making an image smaller may reduce quality slightly, but PixelSwift uses smart processing to keep the result as sharp as possible. Making an image larger can cause some blurriness — it's always best to start with a high-resolution original.
Scaling changes the overall dimensions of your entire image — making it larger or smaller while keeping all content visible. Cropping cuts away parts of the image to focus on a specific area. PixelSwift's resizer uses scaling to preserve your complete image.
Common sizes: Instagram post 1080×1080px, Instagram story 1080×1920px, Facebook cover 820×312px, Twitter/X header 1500×500px, LinkedIn banner 1584×396px. Use PixelSwift's quick presets to resize to these dimensions easily.
Yes. Enable 'Lock Aspect Ratio' (on by default) — when you change the width, the height adjusts automatically to maintain the original proportions. This prevents any stretching or squishing.
For printing photos, your image needs to be large enough — about 300 pixels per inch of print. For example, to print a standard 4×6 inch photo, you need at least a 1200×1800 pixel image. For screens and websites, smaller sizes work fine.
