Frequently asked questions

Does resizing reduce file size?

Yes, usually significantly. Halving the dimensions cuts the pixel count to a quarter, which dramatically reduces JPG and PNG file sizes. WebP often shrinks further than the equivalent JPG at the same visible quality.

Is the resampling high quality?

The browser canvas uses bicubic or bilinear interpolation depending on the platform. Results are sharp for downscales; large upscales naturally show softness or blockiness regardless of tool.

Are my images uploaded?

No. Resizing runs entirely with Canvas in your browser, so the file is never uploaded.

Can I batch resize multiple images at once?

Currently the tool resizes one image at a time. Batch mode is on the roadmap for a future release.
