FAQ
Frequently asked
Is my image uploaded to a server?+
No — resizing happens entirely in your browser using the Canvas API.
Which formats can I output?+
PNG (lossless), JPG (lossy with quality slider), WebP (best compression).
Will resizing reduce quality?+
Downscaling with high-quality smoothing (which this tool uses) is nearly lossless. Upscaling above the original resolution will interpolate pixels.
