Frequently Asked Questions
How do I resize multiple images at once?
Simply select multiple images using the file picker or drag & drop. All images will be processed with the same settings for consistent results.
What makes your resizer better than others?
We use advanced Lanczos resampling algorithms, support 50+ formats including modern AVIF/WebP, offer social media presets, and process everything locally for maximum privacy and speed.
Can I resize images for social media?
Yes! We have built-in presets for Instagram posts/stories, Facebook covers, YouTube thumbnails, LinkedIn banners, Twitter headers, and more.
What output formats are available?
You can keep the original format or convert to JPEG, PNG, WebP, or AVIF. WebP and AVIF provide up to 50% smaller files with the same quality.
Will resizing affect image quality?
Our advanced algorithms preserve quality during downscaling. For upscaling, we use AI-enhanced interpolation that maintains sharpness better than basic methods.
Is there a file size limit?
No hard limits. Processing is limited only by your browser's available memory. Very large images (100MP+) may take longer to process.
Can I save my resize settings?
Currently, settings are maintained during your session. We're adding a preset save feature in the next update for workflow automation.
