Add up to 30 JPG images (up to 50 MB each) and convert them to PNG, which stores every pixel losslessly so further edits and saves don't add new compression artifacts. You can also choose WebP or AVIF as the output. The conversion runs in your browser, and the results download one by one or as a ZIP.

PNG is the format to use when an image will be edited again, when it contains text or sharp graphics, or when you plan to add transparency later. This JPG to PNG converter turns your JPG files into PNG without uploading them.
How to convert JPG to PNG
- Add your JPG files by dragging them in or clicking to browse.
- Keep PNG as the output.
- Download the PNG files, or all of them as a ZIP.
Why convert JPG to PNG?
PNG compression is lossless, so the image you convert is stored exactly, and saving it again later won't degrade it. That makes PNG a good working copy for images you'll edit several times.
PNG also supports transparency through an alpha channel. A JPG has none, so the converted PNG starts fully opaque, but you can then cut out the background, for example with the background remover, and keep the result as a transparent PNG.
JPG vs PNG comparison
| Feature | JPG | PNG |
|---|---|---|
| Transparency | No | Yes |
| File size | Small | Larger |
| Compression | Lossy | Lossless |
| Best for | Photos, web images | Graphics, logos, screenshots |
| Repeated saving | Loses quality each time | No loss |
PNG for editing workflows
Each time you save a JPG, lossy compression runs again and artifacts build up. After several saves at quality 85, edges and gradients can look noticeably worse. Converting to PNG gives you a lossless master you can edit and save as often as you like. A common workflow is to edit in a lossless format and export JPG only as the last step for the web.
When lossless matters most
Screenshots, diagrams, interface mockups, infographics and anything with text benefit most. JPG struggles with sharp edges and flat colors, producing smudges around letters and lines. Converting to PNG stops further damage, although it can't remove artifacts the JPG already has. For crisp screenshots, save them as PNG from the start.
The transparency factor
Converting can't create transparency on its own, since the JPG has no transparency to carry over. What PNG adds is the ability to hold it. After converting, you can remove the background or make parts of the image transparent in an editor. Designers often do this with product photos and logos they want to place over other content.
File size reality check
Expect larger files. PNG keeps every pixel, while JPG gets its small size by discarding detail, so a photo can grow several times larger as a PNG. Images with flat colors, text and sharp edges grow less, because PNG compresses those areas well. If size becomes a problem, the PNG compressor can shrink the PNG losslessly, or you can use WebP lossless instead.
Who uses it
Graphic designers convert photos into PNG working copies and prepare graphics for transparency. Web developers convert interface images and icons. Content creators convert images they plan to edit for social media graphics.
Technical specifications
Input is JPG (JPEG), and output is PNG, WebP or AVIF. Each batch takes up to 30 files of up to 50 MB and 64 megapixels each. PNG output is lossless. Processing happens in your browser, and files are never uploaded or stored on a server.
Frequently Asked Questions
Why convert JPG to PNG?
PNG is lossless and supports transparency, which makes it better for graphics, logos, screenshots and images you will edit more than once.
Will the image quality improve when converting JPG to PNG?
No. PNG keeps the current quality and prevents further loss, but it can't restore detail the JPG compression already removed.
Can I convert multiple JPG files to PNG at once?
Yes. Add up to 30 JPG files, convert them in one go, and download them as a ZIP.
Is this JPG to PNG converter really free?
Yes. There are no fees, watermarks or sign-up.
Will the file size increase when converting JPG to PNG?
Yes, usually. PNG stores every pixel without loss, while JPG discards detail to stay small. Photos grow the most.
What's the maximum file size I can convert?
Each JPG can be up to 50 MB and 64 megapixels.
Can I add transparency to JPG images?
Not in this step, because a JPG has no transparent areas to keep. Convert it to PNG first, then remove the background with the background remover or an image editor to make parts transparent.
Should I edit images as PNG or JPG?
Edit in a lossless format such as PNG when you can, because it keeps its quality through repeated saves, while a JPG loses a little each time. Export to JPG at the end for the web or when file size matters.
Is PNG better than JPG for printing?
PNG avoids new compression artifacts, so it's a safe choice for printing graphics and screenshots. For photos, a high-quality JPG usually prints just as well. Some print shops ask for PDF or TIFF, so check their requirements.
