Built for real page-speed work
Image weight is still the single biggest reason pages load slowly. Our compressor re-encodes your photo through the browser's own Canvas pipeline and lets you drag the quality slider while watching the output size update live, so you can stop at the exact point where the file is small but the picture still looks right. Typical photography drops sixty to eighty percent before any visible change appears.
The resizer works to exact pixel dimensions with an optional aspect-ratio lock, which matters when a marketplace or an ad platform rejects anything that is not precisely 1200 by 628. Converting between JPG, PNG, BMP and PDF uses the same local pipeline, so a batch of twenty product shots is processed as fast as your CPU can draw them — there is no queue and no per-file upload.
