ConvertNest's Image Compressor uses the browser's native canvas rendering engine to compress image files.
This helps you fit images within attachment limits or speed up webpage loading times, while keeping files securely in your browser.
We support standard JPG, JPEG, and PNG files. For PNG uploads, they will be outputted as optimized JPEGs to achieve maximum compression sizes.
A quality level of 70% to 80% is the sweet spot. It provides significant size reduction (often 50% to 80% savings) with no visible quality loss.
No, never. The compression runs entirely in your local browser window. Your photos remain fully private.
