What this tool does

Choose an image, set the output format and an optional maximum file size, then compare the processed result with the original. A size limit is a target, not a promise of an exact byte count.

How to use it

Choose one image and review its original details.
Set the output format and maximum size, then process the image.
Check the actual bytes, pixels, format and preview before downloading.

Check the output

The file-size result is measured from the output Blob.
Check dimensions and format as well as the size result.
A passed maximum does not guarantee acceptance by another service.

Common reasons it may fail

Detailed images may need stronger lossy compression or fewer pixels.
PNG can be larger than JPG for photographs.
Device memory or browser decoding can limit very large inputs.

Real limitations

Compression can change visible quality.
The tool does not pad output to an exact size.
Normal image processing stays in browser memory.
