It depends on the format you choose. Converting to PNG or BMP keeps the quality the same since they don't compress images. WebP gives you a smaller file with very similar quality. PDF just wraps your image into a document — no quality loss there either.
Go with JPG to WebP. WebP files are usually 25–35% smaller than JPGs, and they still look great on most modern browsers and apps. It's the easiest way to shrink your file without making it look worse.
Yes, all tools on this page support batch conversion. Just select multiple files at once and they'll all be converted together — no need to do them one by one.
Completely. Your files are processed directly in your browser and are never stored on our servers. Once the conversion is done, the files are gone — we don't keep copies of anything you upload.
Sometimes people or companies ask for documents in PDF format — like for forms, ID proofs, or printed materials. Converting your JPG to PDF makes it look more professional and ensures it prints or displays the same way on every device.
