Acerca de la herramienta JPG a PNG
This converter turns a JPG (JPEG) photo into a PNG file. The practical reason to do this: PNG is a lossless format. A JPG loses a little quality every time it is edited and re-saved, while a PNG can be opened, edited and saved repeatedly with zero degradation - which is why designers convert to PNG before retouching, annotating or compositing an image. PNG is also the format many tools, CMSs and print workflows require for logos, screenshots and graphics with text. Note the honest trade-off: converting cannot restore detail the JPG compression already discarded, and PNG files are usually larger than the source JPG because nothing is being thrown away.

JPG vs. PNG: which format for what
JPG is best for photographs going to the web or email: small files, and the quality loss is invisible for one-time viewing.
PNG is best for screenshots, logos, charts, text-heavy images, and any image that will be edited again - its lossless compression keeps sharp edges crisp.
If file size matters more than anything (page speed, email limits), consider WebP via the WebP Converter: it beats both JPG and PNG on size for most images.
Preguntas frecuentes
Why convert JPG to PNG at all?
PNG is lossless, so the image survives repeated editing and saving without degrading. Convert before retouching or annotating a JPG, or when a website, tool or print shop specifically requires PNG.
Will converting to PNG improve my image quality?
No. Conversion preserves the image exactly as it is but cannot recover detail that JPG compression already removed. It prevents further quality loss; it does not undo past loss.
Will the PNG be transparent?
No. JPG has no transparency, so there is nothing to carry over - the PNG will have the same solid background as the JPG. To make the background transparent, use the Background Remover tool instead.
Why is my PNG file larger than the JPG?
JPG achieves small files by discarding detail; PNG keeps everything, so photos in particular grow in size. That is the normal cost of a lossless format.
Can I convert multiple JPG files?
Convertir them one at a time - each conversion takes a few seconds and the download appears on the same page.
