How to use the Image Compressor
- Drag your image onto the drop zone, or click it to choose a file from your device.
- Move the Quality slider — lower values mean a smaller file but more visible compression.
- Compare the original and compressed size shown in the stats.
- Click "Download compressed image" to save the result.
How it works
Compression works by re-encoding the image as JPEG at a lower quality setting, which reduces file size by discarding some visual detail that's usually invisible at normal viewing sizes. For example, a 2 MB photo straight from a phone camera can often shrink to under 300 KB at 70% quality with no visible difference. Because the encoding runs on the browser's built-in Canvas API, the image is read into memory locally and never leaves your device — there's no upload step to skip.
Frequently asked questions
Is my image uploaded to a server?
No. The compression happens with the Canvas API directly in your browser tab. The image data never leaves your device.
What image formats are supported?
You can upload JPG, PNG, or WEBP. The compressed output is saved as a JPG.
Is there a file size limit?
No artificial limit is enforced — very large images may just take a moment longer to process, since your own device does the work.
