JPG to PNG Converter
Convert JPG to PNG for a lossless copy with transparency support — or PNG to JPG for a smaller file. Free, up to 10 files at once, and it runs in your browser, so nothing is uploaded.
PNG is lossless — no quality setting needed. Transparency is preserved.
JPG or PNG — which should you use?
JPG compresses photographs into small files, which makes it the right choice for photos, camera images, and anywhere file size matters — like upload forms with a KB limit. The trade-off is that it is lossy and has no transparency.
PNG is lossless and supports a transparent background, so it is the right choice for logos, icons, screenshots, diagrams, and text — anything that must stay perfectly sharp or sit on a transparent layer. The trade-off is a larger file for photographs. Convert JPG to PNG when you need a lossless working copy or transparency; convert PNG to JPG when you need a smaller file and do not need transparency.

JPG to PNG — FAQ
How do I convert a JPG to PNG?
Choose 'JPG to PNG' above, upload your JPG (up to 10 at once), and download the PNG. PNG is lossless, so no quality is lost in the conversion — though note that converting a JPG to PNG cannot restore detail that JPG compression already removed.
How do I convert a PNG to JPG?
Choose 'PNG to JPG' above, upload your PNG, and download the JPG. JPG files are smaller, which is useful for photos and upload forms. Any transparent areas in the PNG are filled with white, since JPG does not support transparency.
Should I use JPG or PNG?
Use JPG for photographs and anywhere small file size matters — it compresses photos efficiently. Use PNG for logos, icons, screenshots, text, and any image that needs transparency or must stay perfectly sharp, since PNG is lossless and supports a transparent background.
Does converting JPG to PNG improve quality?
No. PNG is lossless, so it preserves exactly what is in the JPG — but it cannot add back detail that JPG compression already discarded. Converting to PNG gives you a lossless copy for further editing, not a higher-quality original.
Why is my PNG bigger than the JPG?
PNG is lossless and stores every pixel exactly, so for photographs it is usually much larger than the equivalent JPG. That is expected. If you need a smaller file for a photo, JPG is the better format.
What happens to a transparent PNG converted to JPG?
JPG does not support transparency, so any transparent areas are filled with white when converting PNG to JPG. If you need to keep transparency, keep the file as PNG or convert to WebP instead.
Is my image uploaded to a server?
No. This tool runs entirely inside your browser. Your images never leave your device, so nothing is uploaded anywhere.
