How Image Compressor works

Re-encode PNG, JPEG or WebP locally, with real output byte counts and optional format changes.

Steps

Choose an image, select an output format and quality, process it and inspect the preview before downloading.

Example to check

JPEG quality affects lossy compression; the PNG quality control is disabled because canvas PNG encoding does not use that setting.

Limits and review

Compression is not guaranteed to shrink a file. Larger outputs are labelled honestly. JPEG removes transparency using a white background. Images are limited to 50 MB, 16,384 pixels per side and 32 million pixels overall.

Where your data goes

Your selected files and entered content are processed in your browser. Processing does not upload them to a conversion, QR or AI API. The site serves the scripts, fonts and any OCR models needed for the task.

Practice: measure quality rather than guessing

Start with a detailed photograph and note the source dimensions and actual byte count. Export the image once as a JPEG at a moderate quality setting and once as a PNG. Look closely at sharp lines, text, hair and fine textures before selecting a version. The smaller export is not always the better one: readable detail and the destination's format requirements matter.

What can be lost?

Lossy compression can create ringing near sharp edges or blocking in flat regions. A browser export may also change metadata or color handling. Use a copy when preserving the exact original matters, and always check the final downloaded file in the intended app.
