Predictable resizing without hidden uploads
Fit or exact
Fit mode keeps the original aspect ratio inside a bounding box. Exact mode uses both requested dimensions and may change the aspect ratio.
Batch without memory spikes
Files are decoded and encoded sequentially. Batch results are written into a local ZIP rather than keeping every decoded image alive.
No accidental enlargement
Smaller images remain at their original dimensions unless you explicitly allow upscaling.
New privacy-safe derivative
The export is newly encoded and does not copy embedded metadata. The selected source file is never mutated.
