Why convert PNG to JPG?
PNG is the lossless workhorse of the web: every pixel survives compression, it supports full alpha transparency, and it is the right format for screenshots, logos, UI captures and anything with sharp edges or text. That fidelity has a cost — PNG files are routinely 5 to 10 times larger than an equivalent JPG.
That size becomes a problem the moment a file has to go somewhere. Job application portals, government forms, e-commerce listings, insurance claims and email attachments all enforce limits (often 2–5 MB) and many accept JPG but silently reject oversized PNGs. Social platforms and CMS pipelines recompress images anyway, so shipping a 25 MB PNG buys nothing.
ShiftRaw converts PNG to JPG entirely in your browser. Your browser already decodes PNG natively, so conversion is instant and pixel-honest: quality 92% is visually identical for photographs while typically cutting 70–90% of the file size. Transparent areas are flattened onto white, so cut-outs and logos keep the look you intended.
Best for: photographs, scans and any image headed for an upload form, email or a size-limited portal. Keep PNG when you need transparency or pixel-exact text and line art — for everything else, JPG at 92% is the sensible delivery format. Keep the original PNG as your master.
