Choose the output for its purpose
Use WebP for a modern website image with transparency, JPG for photos with a white background, and PNG when lossless rendered pixels matter. Keep originals because re-encoding can change metadata and color profiles.
Reduce dimensions or choose a region
The resizer fits images inside a requested box when proportions are locked; unlock it for exact shared dimensions. Crop coordinates refer to original pixels, even when the preview is smaller. Enlarging does not restore detail.
Check actual compression results
Quality and target-size compression create JPG or WebP. A missed target is explicitly marked and may need smaller dimensions. PNG Compressor offers lossless optimization or lossy RGB color reduction. Compare actual sizes and retain originals; on phones use smaller batches.
