Browse FileAbout Image Compressor
This tool compresses images directly in the browser using file reading, canvas drawing, and canvas export instead of uploading the file to a server.
When exporting through `canvas.toDataURL(type, quality)`, the quality value is relevant for JPEG and WebP output, while PNG does not use that quality parameter in the same way — PNG output stays lossless and preserves transparency.
Choosing the right settings
- Use JPG output for photos without transparency — it compresses best at 60-80% quality.
- Keep PNG for logos, icons, or screenshots that need a transparent background.
- WebP often gives smaller files than JPG at similar visual quality, if your use case supports it.
- Always preview the compressed result before downloading to confirm quality is acceptable for your use.
Frequently Asked Questions
No, all compression happens locally in your browser using the Canvas API. Images are never uploaded, keeping them private and making compression instant.
JPG and WebP compression is lossy, so higher compression reduces file size but can introduce minor quality loss. A quality setting of 70-85% usually balances size and quality well.
No, PNG is lossless and doesn't use a quality slider like JPG or WebP. It compresses by optimizing pixel data while preserving transparency, so size reduction is typically smaller than JPG.
For web use, 60-80% usually reduces file size significantly with minimal visible loss. For printing or archival purposes, use 85% or higher.
PNG uses lossless compression, so complex images with many colors compress less than simpler ones. Converting to JPG or WebP, if transparency isn't needed, usually gives much smaller files.
This tool supports images up to 10MB. Since compression happens in your browser, very large images may take a few extra seconds depending on your device.
