Questions about ️ Image Compressor
Is the target size guaranteed?
No. It depends on the format and allowed dimensions. Unmet targets are explicitly marked. Change format or allow further resizing to try again. One KB here means 1024 bytes.
Is transparency preserved?
PNG and WebP preserve transparency; JPEG uses a white background. Animated images are not supported. Format conversion can increase file size, which is also reported.
What are the limits?
Up to 20 files, 20 MB per image, 100 MB per batch and 40 megapixels per image. The quality slider does not affect lossless PNG compression; reducing dimensions can still make it smaller.
Are images uploaded or stored?
Images are processed in your browser and not saved by the website. Download results before closing the page. The original is retained only when it meets the requested format, dimensions and size limit and is smaller than the encoded result.
