Compress image, without the upload step
Large image files take longer to share, use more storage, and can slow down a page. This free image compressor redraws each selected picture in your browser and lets you choose the balance between visual detail and file size. JPEG is a practical choice for photographs; PNG is useful when sharp edges or transparency matter.
Add one image or a batch, set a quality level, and process the files locally. The result card shows the original and new file sizes so you can make an informed choice. There is no account, watermark, or upload queue. Your device does the work, and you download only the versions you want to keep.
The browser applies EXIF orientation while decoding and limits extremely large dimensions before encoding. Compression depends on image content, dimensions, format, and quality, so results vary. If you have a strict size requirement, use the under-100KB tool and check the final file size before attaching or publishing it.
Files are decoded and processed on your device. They are not uploaded to an ImageKit server, and the original files are never overwritten.

Frequently asked questions
Are my images uploaded?
Your image stays in this browser tab. Processing runs locally on your device; the image file is not sent to an ImageKit server.
Does compression reduce image quality?
Lossy compression removes some image data. Lower quality settings usually create smaller files, so compare the preview and size before downloading.
Which formats can I compress?
The tool accepts browser-readable images and produces JPEG output. Browser support for HEIC and other camera formats varies.
