Frequently Asked Questions
What is the best way to resize a JPEG for social media?↓
Use Cover fit mode and enter the platform's required dimensions. Instagram posts use 1080x1080, Twitter headers 1500x500, Facebook covers 820x312.
Does resizing JPEG reduce quality?↓
Slightly. JPEG is re-encoded when resized which may cause minor quality loss. Set quality to 90%+ to minimize any visible degradation.
Can I resize a JPEG without changing aspect ratio?↓
Yes. Enable the aspect ratio lock before entering dimensions. Change either width or height and the other value adjusts automatically.
How do I make a JPEG smaller for email?↓
Most email systems require images under 1MB. Resize to 1200px wide and use our compressor to reduce file size further if needed.
