Before/after sizes

JPG, PNG and WebP

All three common web formats are supported.

Supported formats

  • Input: JPG/JPEG, PNG or WebP, one file up to 20 MB
  • Output: compressed image in the same format as the original

Privacy and security

Compression runs on your device using the browser canvas. The image is re-encoded locally and downloaded from your browser — nothing is sent to a server.

Limitations

  • One image at a time, up to 20 MB.
  • PNG is lossless — big savings come mainly from re-encoding to JPG/WebP quality levels.
  • Higher compression visibly reduces quality; the slider is there so you choose the trade-off.

Frequently Asked Questions

Is it safe to compress my images here?

Yes. Your image never leaves your device — compression happens entirely in your browser using the Canvas API. Nothing is uploaded to a server.

Why doesn't the quality slider shrink my PNG much?

PNG is a lossless format, so it has no quality setting to trade away for size. For real PNG savings, choose 'Convert to JPG' or 'Convert to WebP' as the output format — both are lossy and compress dramatically better.

What quality level should I pick?

80–85% is usually indistinguishable from the original while cutting file size by half or more. Drop to 60% or below for much smaller files when quality matters less (e.g. thumbnails).

Will compression change my image dimensions?

No. Your image keeps its exact pixel dimensions — only how aggressively the data is encoded changes.

Do I need to install anything?

No. Everything runs in your browser with JavaScript. Drop in an image, adjust the slider, and download the compressed result.
