How to use it
- Choose a static image.
- Set format, quality and maximum width, or an optional target size.
- Compress, inspect the preview and download the new copy.
Understand the size saving
- Input
- Illustrative original: 800 KiB; output: 200 KiB
- Result
- 600 KiB smaller; 75% saving
This is a size calculation, not a promise that every photo will compress by 75%. An already optimized image can become larger. Inspect fine text, faces and transparency in the output before using it. The size target is best effort.
Useful situations
- Fit a photo within an upload limit.
- Prepare a lighter image for a webpage or message.
Limits and supported formats
Static PNG, JPEG or WebP up to 10 MiB, 20 megapixels and 8192px per edge; output up to 4096px. No SVG, GIF, HEIC or animation. JPEG flattens transparency onto white. Browser colour conversion can vary; keep the original. A requested target is best-effort and explicitly reported if unreachable; negative savings means the output is larger.
Privacy
We do not store tool content or results. Optional usage events do not include files, filenames, text, passwords or QR contents. Reset when finished and save any output you need on your own device.
Questions about this tool
Can it always reach my target size?
No. Image detail, dimensions and format affect the result. Reduce dimensions or choose a lossy format and review quality; the tool never labels a larger result as a saving.
