- What it does: saves your JPG as a PNG file. The picture looks the same; only the file type changes.
- When it helps: when something only accepts PNG, when you will edit and save an image many times, and for screenshots, text and graphics.
- What to expect: the PNG is usually bigger than the JPG, especially for photos.
- What it cannot do: it does not make a blurry or blocky JPG sharper, and it does not make the background transparent on its own.
The short answer
How do I convert JPG to PNG?
- Add your JPGs. Drag them into the box, or click it to choose files. Add more at any time with + Add More.
- Press Convert Images. Three files are converted at the same time, and each one shows its old and new size when it is done.
- Save the PNGs. Press Download under an image to save it on its own, or Download All (ZIP) to save every file in one ZIP.
Each PNG keeps the name of the original file. Press the X button to clear the list and start a new batch.
What is the difference between JPG and PNG?
JPG makes files small by leaving out fine detail that is hard to see. That works well for photos, but the lost detail is gone for good, and every time a JPG is edited and saved again it loses a little more. PNG stores the image without that kind of loss and can have transparent areas, but photos take much more space as PNG.
| Use JPG when | Use PNG when |
|---|---|
| You store or share photos | The image needs transparent areas |
| File size matters, such as for email | The image has text, lines or app screenshots |
| You post on social media | You will edit and save it many times |
| You send it as an attachment | It is a logo, icon or diagram |
| It goes on a website (or use WebP) | An app, form or game engine asks for PNG |
Problems this tool solves
- "The upload form says PNG only." Convert the JPG here and upload the PNG. The picture is the same, so the form accepts it.
- "My design app or game engine wants PNG files." Add the whole set of JPGs, convert them in one go and download a single ZIP.
- "The image gets worse every time I edit it." Convert to PNG once, do all your editing on the PNG, and only make a JPG at the very end if you need a small file. Saving a PNG again does not add new damage.
- "My screenshot was saved as a JPG and the text looks messy after each change." Work on a PNG copy, so arrows, notes and highlights you add stay crisp.
- "I want to remove the background." You do not need to convert first: the AI Background Remover accepts JPG and gives you a transparent PNG. For a logo or product on a plain background, use the Transparent Background Maker.
Does converting JPG to PNG improve quality?
No. When a JPG was first saved, some detail was thrown away, and converting cannot bring it back. Blur, blocky squares and colour smudges in the JPG are copied into the PNG exactly as they are. What PNG does is stop things from getting worse, because saving a PNG again does not compress it again.
One thing is specific to this converter: to keep files a sensible size, the PNG it writes is limited to at most 3,686 different colours. Screenshots, logos and graphics almost always use fewer, so they come out as an exact copy. Photos often use more, so smooth areas such as a clear sky can show faint steps of colour. If you need every colour of a photo kept, keep the JPG, or convert to WebP with the JPG to WebP tool.
Will the PNG have a transparent background?
No. A JPG has no transparent parts, so the PNG has the same solid background as the original. Converting only gives you a file type that can hold transparency later. To actually remove the background, use the AI Background Remover for photos of people, pets and products, or the Transparent Background Maker for a logo or object on a plain colour. Both give you a PNG with a see-through background.
Why is the PNG bigger than my JPG?
PNG keeps the image without throwing detail away, and photos are full of fine texture that PNG cannot shrink much. So a photo usually becomes several times larger as a PNG; the tool shows both sizes for each file. Screenshots and simple graphics grow much less, because large areas of flat colour compress well. If the bigger file is a problem, keep the JPG for sharing and use the PNG only where it is required.
What else the tool changes
- Quality: PNG is written at quality 0.9 where the format uses a quality setting. There is no slider on converter pages; use the Image Compressor if you want to choose the quality yourself.
- Size limits: images longer than 4096 px on either side are scaled down to 4096 px. If a converted file would be over 10 MB, it is reduced in steps until it fits.
- Batches: add several files; three are converted at a time. One file downloads directly, two or more come as a ZIP.
- Metadata: EXIF data (camera, date, GPS) and colour profiles are not carried into the new file.
Is it safe to convert private images here?
- Nothing is uploaded. Your browser reads the files from your device and converts them in a background worker in the page. The images never reach Image York or anyone else.
- Your originals stay as they are. The tool makes new PNG files and does not change your JPGs.
- Nothing is kept. The converted files exist only in the open tab and are gone when you close or reload it.
