Logos and graphics
Flat colours and sharp edges look cleaner in PNG, which does not add the blotchy artefacts JPG can leave around text.
Convert JPG to PNG in bulk, free
Add up to 10 JPG photos and get PNG files back in seconds. They are converted inside your browser, so nothing is uploaded and there is no sign-up.
Each file can be up to 25 MB. When you are done, download them one by one or as a single ZIP.
Features
What you get
- Ten files at once
- Add a batch, convert it with one click, and download a ZIP. Each file can be up to 25 MB.
- Nothing uploaded
- The browser does the conversion on your own device, so your photos never reach a server.
- Every pixel kept
- PNG stores the image exactly as the JPG shows it. The picture is the same size and looks the same.
- Names kept
- holiday.jpg becomes holiday.png. If two files would end up with the same name, the second gets a number so neither is lost. You can also add your own text to the start or end of every name.
- Before and after
- Press Compare on a finished file and slide between the JPG and the PNG. Download one file, or a whole batch as a ZIP.
- Free
- No sign-up, no watermark, and no limit on how many batches you convert.
How it works
Convert in four steps
Add your JPGs
Choose files or drag them onto the page. .jpg and .jpeg both work.
Check the list
Each file shows its name, its size in pixels and its file size. Remove any you added by mistake.
Convert
Press the convert button. Each file shows its new PNG name and size when it is done.
Download
Save one PNG, or take the whole batch as a ZIP.
Uses
When PNG is the better format
Screenshots and diagrams
A screenshot saved as JPG can look fuzzy near letters. Converting it to PNG stops it getting worse each time it is edited and saved.
Design and print software
Some tools ask for PNG. Converting first saves a failed upload.
Starting a cut-out
PNG is the format that can hold a see-through background. Convert here, then remove the background in an editor.
JPG and PNG compared
| JPG | PNG | |
|---|---|---|
| Best for | Photos | Graphics, screenshots, logos |
| Compression | Lossy: detail is thrown away to save space | Lossless: nothing is thrown away |
| File size | Small | Larger, often several times bigger for photos |
| Transparency | No | Yes |
| Repeated saving | Loses a little quality each time | No loss |
Choose PNG when you need exact pixels or transparency. Choose JPG when small file size matters more. To go the other way, use the PNG to JPG converter.
How the conversion works
Your browser opens the JPG, draws it on a canvas at its original size, and saves that canvas as a PNG. All of this happens on your own computer. The file is never sent anywhere, which is why there is nothing to wait for besides the conversion itself.
Frequently Asked Questions (FAQ)
Add your JPG files, press convert and download the PNGs. PNG is lossless, so the PNG shows exactly what the JPG showed, at the same size in pixels. It cannot add back detail the JPG had already lost.
No. A JPG has no transparency, so the PNG is fully opaque. Converting only changes the format. To remove a background, open the PNG in an image editor.
JPG saves space by discarding detail, and PNG keeps everything. For photos a PNG is often several times bigger. If size matters, keep the JPG or use the image compressor.
Up to 10 files per batch, each up to 25 MB. There is no daily limit, so you can start another batch straight away.
No. The conversion runs in your browser on your own device, so your images never leave it.
Files named photo.jpg and photo.jpeg would both become photo.png. The converter keeps both by naming the second one photo-1.png.
Yes. Open More settings to shrink the longest side of big pictures, and to add text to the start or end of every file name. Your settings are remembered on this device for next time.
