Frequently Asked Questions
Is there a file size limit?
There's no strict limit, but very large images (20MB+) may be slow to process depending on your browser and device.
What image formats are supported?
We support JPG/JPEG, PNG, WebP, and GIF. The output format matches your input format.
Will resizing reduce image quality?
Enlarging images can reduce quality. For best results, resize to smaller dimensions. We use high-quality bicubic interpolation.
Are my images uploaded to a server?
No! All processing happens locally in your browser using the Canvas API. Your images never leave your device.
Can I resize multiple images at once?
Currently this tool processes one image at a time for best quality control. Batch processing may be added in the future.
