Frequently asked questions
What is the difference between crop, fit, and stretch modes?+
Crop: scales the image to fill the target dimensions, then centre-crops any overflow — no letterbox, no distortion. Fit: scales to fit entirely within the target, adding padding/fill on edges. Stretch: ignores aspect ratio and distorts to fill exactly. Use crop for social media, fit for product thumbnails, and stretch rarely — it distorts subjects.
Can I resize to larger dimensions than the original?+
Yes, but this is upscaling — quality degrades based on how much you enlarge. For clean upscaling, use the AI Upscaler tool first (which reconstructs detail at 2×), then resize to your exact target dimensions.
What pixel dimensions does WordPress use for image sizes?+
WordPress generates several sizes on upload: thumbnail (150×150), medium (300×300 max), medium_large (768px wide), and large (1024×1024 max). Custom themes and plugins define additional sizes. Resize to your theme's exact media slot dimensions to prevent WordPress from re-cropping at an unexpected position.
