Frequently asked questions
Choose “By target size” and enter the size in KB. The tool looks for the highest quality that fits; if even a reasonably low quality is not enough, it reduces the image dimensions and tells you.
PNG is a lossless format: the browser saves it again without removing detail, so the saving is usually small. For photos, switching to JPG or WebP reduces the size much more. If the result were larger than the original, the tool keeps the original and tells you.
No. Your own browser does the compression and the images are not sent to JapalTools or anyone else. Also, the compressed image is created anew without the original's metadata (such as EXIF), except when the original is kept because it was smaller.
