Image Compressor questions

Short answers, then the practical details.

Which image formats can I compress?

The image compressor accepts valid JPG, PNG and WebP files and can export any of those formats. Choose up to 20 images, with a 100 MB batch limit and 50 MB per source. Output quality controls apply to JPG and WebP; PNG uses lossless pixel encoding. Output is capped at 16 megapixels and 8192 pixels per side, so larger sources may also be resized.

Why might a PNG not get smaller?

PNG does not use the same lossy quality setting as JPEG, so re-encoding an already efficient PNG may not reduce its size. Choose JPG or WebP when appropriate, or use a target-size tool that can reduce dimensions. The preview and actual byte size show the real result.

Does image compression preserve transparency?

PNG output preserves alpha transparency, and WebP can preserve it as well. JPG cannot store transparency, so transparent areas are filled with white. Choose the output format deliberately and inspect the preview before saving, especially for logos, cutouts or graphics intended to sit on a colored background.
