Frequently Asked Questions
- How do I resize an image without losing quality?
- Enter your target width or height with aspect ratio locked. We use high-quality resampling (pica) to keep edges sharp when scaling down.
- Can I resize for social media?
- Yes. Set exact pixel dimensions for Instagram, Facebook, LinkedIn, or any platform, then optionally compress before downloading.
- Will resizing change the file format?
- You choose the output format. Resize first, then export as JPEG, PNG, or WebP with optional compression.
- Is there a maximum image size?
- You can resize images up to 50 MB. Very large files may take longer to process depending on your device.
