FAQ
Does this upload my image to a server?
No. The resize happens entirely in your browser using the HTML5 Canvas API. Your image data stays on your device.
What's the maximum image size I can resize?
Limited only by your browser's memory. Typical phones handle up to 8000×8000 pixels; desktops handle 16000×16000 or larger.
Will resizing reduce quality?
Downsizing produces sharp results with virtually no quality loss. Upsizing (e.g. taking a 1080p image to 4K) interpolates pixels and will look softer — for upsizing we recommend a dedicated AI upscaler like Upscayl.
Which format should I pick?
Use WebP for the best balance of quality and file size for both photos and graphics. Use JPG if you need maximum compatibility with older systems. Use PNG when you need transparency.
Can I resize multiple images at once?
This version handles one image at a time. Bulk-resize support is on the roadmap.
