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.
