All standard JPG and JPEG files are supported.
Output is a full-quality lossless PNG file, perfect for further editing.
Your images stay on your device for browser-side workflows. Privacy-aware conversion.
Key Takeaways
- JPG to PNG conversion is lossless from the JPG you start with, but it cannot recover detail already lost to JPG compression - always begin with your highest-quality source.
- Use PNG when you need transparency or crisp edges (logos, text, screenshots); keep JPG for photographs where smaller file size matters.
- This converter runs in your browser using the Canvas API, so the image is processed on your device, and you can convert several files in one batch.
- Expect the PNG to be noticeably larger than the JPG - that is normal for lossless format on photographic content.
When to Convert JPG to PNG
Use PNG for logos and graphics
PNG is ideal for logos, icons, and graphics with sharp edges or text. JPG compression creates visible artifacts around hard edges.
Use PNG when you need transparency
JPG does not support transparency. If you plan to use the image on a colored background or overlay it, convert to PNG first.
Quality limitation to know
Converting JPG to PNG does not recover quality lost during JPG compression. The PNG will be lossless from that point, but original artifacts remain. Always work from your highest-quality source file.
File size tradeoff
PNG files are typically 2-5x larger than equivalent JPG files for photos. For web images where transparency is not needed, keep the JPG format to reduce page load time.
How to Convert JPG to PNG
Select your JPG files
Drag and drop one or more JPG (or JPEG) images into the box above, or click Browse to pick them from your device. You can queue several files at once for batch conversion.
Convert in your browser
Press Convert. The conversion runs locally using your browser's Canvas API, so the image is processed on your own device - nothing is uploaded to a server for this workflow.
Download the PNG
Each converted PNG appears with its original and output size. Click Download to save it. PNG output is lossless, so the result preserves every pixel of the decoded JPG.
JPG vs PNG: What Changes
Both are image formats, but they are built for different jobs. This table shows what actually differs when you convert from JPG to PNG.
| Property | JPG (JPEG) | PNG |
|---|---|---|
| Compression | Lossy - discards detail to shrink size | Lossless - keeps every pixel |
| Transparency | Not supported | Full alpha transparency |
| Best for | Photographs, complex scenes | Logos, text, screenshots, sharp edges |
| Typical file size | Smaller | 2-5x larger for photos |
| Re-saving quality | Degrades each save | No further loss |
| Animation | No | No (use APNG/GIF) |
Should You Convert JPG to PNG?
Convert to PNG when...
You need a transparent background, the image has text or sharp edges, you will edit and re-save repeatedly, or a platform requires PNG (many app icons and logos do).
Keep it as JPG when...
The image is a photograph headed for the web or email, file size matters more than perfect fidelity, and you don't need transparency. PNG would only make it larger without visible benefit.
Important limitation
Converting JPG to PNG does not recover detail already lost to JPG compression. The PNG is lossless from that point forward, but existing artifacts remain - always start from the highest-quality JPG you have.
Batch tip
Converting a folder of JPGs? Drop them all in at once. Each file is processed independently in your browser, so a large batch won't upload anything or hit an account limit.
Common Problems and Fixes
The PNG is much larger than the JPG
That's expected. PNG is lossless, so photographic images become several times larger. If size matters and you don't need transparency, keep the JPG instead.
The image still looks blurry or blocky
Conversion can't add detail that isn't there. Blockiness comes from the original JPG compression. Re-export from the original source at higher quality before converting.
I wanted a transparent background
Converting a JPG to PNG does not create transparency - JPG has none to begin with, so the background stays solid. Use an image editor or a background remover to add transparency, then export as PNG.
My file won't load
Make sure the file is a real JPG/JPEG. Files renamed to .jpg but saved in another format may fail to decode. Re-save it as JPG from an image editor and try again.
Why Convert JPG to PNG?
PNG is a lossless image format that's ideal for images you plan to edit, screenshots, graphics with text, and designs with sharp edges. Converting JPG to PNG ensures no further quality loss when editing or re-saving the image.
Frequently Asked Questions
Why would I convert JPG to PNG?
You would convert JPG to PNG when you need to edit the image further and want to avoid additional quality loss from re-saving as JPG.
PNG is also needed when you want to add transparency to an image or combine it with other design elements.
For screenshots, logos, and icons, PNG produces sharper results than JPG.
Will PNG look better than JPG?
Converting JPG to PNG will not improve the quality of the original image. Any compression artifacts from the JPG will still be present in the PNG.
What PNG guarantees is that no additional quality loss occurs from that point forward.
For the best quality, always start from the original uncompressed source image.
Is PNG file size larger than JPG?
Yes. PNG is a lossless format and produces larger files than JPG, especially for photographs.
For photos intended for web use, JPG is almost always the better choice due to smaller file sizes.
For graphics, icons, and images with text, PNG is worth the larger file size for superior quality.
Is my data sent to a server?
No. All conversion happens in your browser using the HTML5 Canvas API.
Your images stay on your device for browser-side workflows. This is safe even for sensitive or private photos.
We do not store, log, or transmit any images you upload.
Can I convert PNG back to JPG?
Yes - use our PNG to JPG Converter to convert back.
You can choose the JPG quality level to balance file size and image quality.
Note that going from JPG to PNG to JPG will result in quality loss from both JPG compressions.
Does the PNG support transparency?
The PNG format supports transparency, but the converted image will not have transparent areas since JPG images don't have transparency data.
To create a PNG with transparency, use a background removal tool first.
Our Background Remover tool can remove the background, and the result can be saved as a transparent PNG.
Does it work with JPEG files (.jpeg extension)?
Yes. JPG and JPEG are the same format. Both .jpg and .jpeg file extensions are accepted.
The output PNG file will have the .png extension.
The conversion process is identical regardless of whether the input file has a .jpg or .jpeg extension.
Is there a file size limit?
There is no hard limit. The converter runs in your browser and is limited only by available memory.
Large photos (20MB+) convert in a few seconds on modern devices.
For very large image collections, consider using our batch Image Converter.
