Image formats and compression
JPG and WebP can trade a small amount of visual detail for a smaller file. PNG uses lossless compression, so its quality does not change with the quality control. If a same-format result would be larger, this tool keeps the original file instead.
A different job
Compression vs. resizing
Compression changes how image data is stored. Resizing changes the pixel dimensions. This tool keeps the original dimensions by default. If you need an exact width or height, use the Image Resizer.
Common questions
About image compression
Are my images uploaded?
No. Compression and format conversion run locally in your browser. The selected image files are not sent to HandyPebble or a third-party image service.
Will compression reduce image quality?
JPG and WebP compression can remove some detail. Balanced is a practical starting point, while Higher quality keeps more detail and usually makes a larger file. Always review important images before using them.
Why did my PNG not get smaller?
PNG compression is lossless, and some PNG files are already efficient. If a same-format result would be larger, the original file is kept. Converting a suitable image to WebP may make it smaller, but it changes the file format.
Does compression change the image dimensions?
Not by default. Dimensions change only when you choose a maximum dimension in Advanced settings. The image keeps its proportions and is never enlarged.
What happens to image metadata?
Newly encoded files usually omit embedded camera and location metadata. If the original file is kept because re-encoding would not make it smaller, its original metadata remains.
What happens to transparent areas when I choose JPG?
JPG does not support transparency. Transparent pixels are placed over the background color shown in Advanced settings, which is white by default.
Can I compress several images at once?
Yes. Every file uses one fixed settings snapshot for that run. Successful current results can be downloaded together as a ZIP, and one failed file does not cancel the rest.
