Image Compressor
Compress JPEG, PNG or WebP images toward a target file size. Optionally reduce dimensions, preview the result and download it without uploading the image.
About this tool
Set a target in KB and choose JPEG, WebP or PNG output. JPEG and WebP allow quality adjustment; PNG does not use the lossy quality setting. If the target cannot be met, the tool says so rather than presenting an oversized file as a success.
Frequently asked questions
What image sizes are supported?
Files up to 20 MB, 32 million pixels and 16,000 pixels on either side. Here 1 KB means 1,024 bytes.
Is the target size guaranteed?
No. Some images cannot meet a small target within the quality and dimension limits. The result clearly indicates whether the target was met.
What happens to transparency, animation and metadata?
JPEG uses a white background for transparent areas. This tool exports a static image and does not deliberately preserve EXIF metadata. Inspect the final file.
