How to convert between PNG and JPG
Upload a JPG or PNG, choose which format you want as output, and click "Convert & download." Converting to JPG lets you set a quality level (JPG is lossy but much smaller); converting to PNG keeps everything pixel-exact but produces a larger file. Note: JPG doesn't support transparency, so a transparent PNG converted to JPG gets a white background.
The two formats solve different problems: JPG's compression makes it the right default for photographs, where a small amount of quality loss is invisible but the file size savings are large; PNG's lossless, transparency-capable format is the right default for anything with flat colors, sharp edges, or text — screenshots, logos, diagrams — where JPG's compression tends to introduce visible smudging around edges.
Does converting PNG to JPG lose quality?
JPG uses lossy compression, so converting from PNG to JPG can introduce minor quality loss, especially on images with sharp text or transparency (transparency is filled with white). Converting JPG to PNG doesn't lose additional quality, but won't recover detail already lost in the original JPG.
When should I use PNG instead of JPG?
PNG is the better choice for screenshots, logos, graphics with sharp edges or text, and anything needing transparency — it's lossless, so edges stay crisp. JPG is better for photographs, where its much smaller file size matters more than the small amount of quality it trades away.
What happens to transparency when converting PNG to JPG?
JPG has no transparency support, so any transparent areas in the PNG are filled with white in the converted JPG.
Is my image uploaded anywhere?
No — conversion happens locally in your browser using the Canvas API. Your eyes only — we never get a look.
Can I convert multiple images at once?
Not currently — this tool converts one image at a time. For a batch of images that all need the same format change, repeat the process for each one.
What quality setting should I use when converting to JPG?
Around 80-90% keeps photos visually indistinguishable from the original while still shrinking the file meaningfully. Go lower (50-70%) if file size matters more than perfect quality, such as for a web thumbnail; stay above 90% only if the image will be printed or heavily zoomed into.
