How it works
Image Compressor re-checks the output before download. Each file in a batch is independent. If compression does not save size, the original bytes are kept.
- 01Add a supported PNG, JPG, WebP, AVIF file. The real type is checked before Image Compressor runs, not only the extension.
- 02Use the controls that belong to this task: Quality, Width, Height. Files over the stated limits are rejected.
- 03Check size, format and page or pixel counts on the result before downloading. Compression tasks keep the original when they do not save space.
