Convert JPG/JPEG images to PNG format entirely in your przeglądarka — your files never leave your device. Converting to PNG gives you a lossless format that won't degrade when edited repeatedly, making it the right choice when you plan to add przezroczysty backgrounds, perform further editing, or need lossless preservation for important images. While PNG files are larger than JPG, they support alpha przezroczystość and won't suffer generation loss from multiple save cycles.

Często Zadawane Pytania

Will converting JPG na PNG improve image quality?

No, it will not improve quality. PNG is a lossless format that preserves all pixel information currently in the JPG, but it cannot recover detail already lost to JPG kompresja. The main benefit of converting to PNG is preventing additional quality loss during future edits and enabling przezroczystość support.

Will I get a przezroczysty background after converting JPG na PNG?

Direct conversion does not automatically create przezroczystość — JPG itself has no kanał alfa. To get a przezroczysty background, convert to PNG first, then use an image editor or background removal tool to erase the background. PNG simply supports storing przezroczystość; the conversion alone doesn't create it.

Will the PNG file be larger than the original JPG?

Yes, typically 2-5x larger. JPG uses high-efficiency lossy kompresja, while PNG uses lossless kompresja. For the same photo, PNG files are significantly larger. If you don't need lossless quality or przezroczystość, stick with JPG.

Why convert JPG na PNG instead of just using JPG?

JPG is ideal for direct viewing, sharing, and wgrywanieing with broadest compatibility. But if you need to edit the image multiple times, add przezroczysty backgrounds, or use it as design source material, PNG is the better choice because repeated saves won't degrade quality.

Are my images wgrywanieed to a server? Is it private?

No wgrywanies. All processing happens locally in your przeglądarka via Web Workers. Your JPG files never leave your device. Processing personal photos and sensitive images is completely safe.

Is batch JPG na PNG conversion supported?

Currently one JPG is processed at a time to ensure local processing stability. Process files one by one for multiple conversions. Batch functionality may be added in future versions.

Can JPG photos from phones be converted?

Absolutely. JPG/JPEG files from phones, cameras, screenshot tools, and any other source all convert normally with no device restrictions.

I actually want smaller files — what should I convert to?

If you want smaller files rather than larger ones, consider converting to WebP using the [JPG to WebP](/image/jpg-to-webp/) tool. At equivalent quality, WebP is 25-35% smaller than JPG and works great for web use.
