What compression can change
Lower quality settings can reduce bytes at the cost of image detail. WebP and JPEG respond to the quality slider; PNG uses lossless encoding and may stay large. Always inspect the result at a useful size before using it.
A target size is a goal, not a guarantee. Some files cannot reach it without changing dimensions or format, and an already efficient source can become larger after re-encoding.
Common questions
Does this keep embedded metadata?
Canvas export normally creates a fresh image without the source camera metadata. Keep your original if you need that information.
Are my images sent to a server?
No. The browser processes your selected files locally.
Want the steps behind the result?
Learn how image dimensions, formats and quality settings affect file size, and how to compare a compressed result without assuming smaller always means better.
