Image Compressor FAQ
Every completed result is measured against your chosen limit before download, so the file you save is already below the target size
To compress image to 20kb, enter 20 KB as the target. Our custom-built algorithm processes the image on your device and verifies that the completed file is below 20,000 bytes before download
It supports JPG, PNG, and WebP files. Set the target to 20 KB, select one or more images, and download each measured result separately or together in a ZIP
Yes. Enter 500 KB and select multiple JPG, PNG, or WebP files. Each image is measured separately, and the ZIP contains only results below 500,000 bytes
Image dimensions, visual detail, and source format influence the compression needed. Enter 150 KB and the tool automatically adapts the image to fit the selected limit
Yes. A strong reduction can lower encoder quality and pixel dimensions. Compare the result with the source before downloading it
A newly encoded successful result is below the selected target. If the original is already below the target, the original is kept and the tool does not claim a saving
Yes. Each result shows the original size, output size, and measured percentage change
No. Source images, full file names, target-size settings, decoded intermediate pixels, compressed images, and ZIP files remain on this device and are not uploaded for processing
Compression can be lossy and can reduce dimensions. Animation and metadata may not be preserved, browser encoding can change color or gamma, and large images or batches depend on available device memory
